ResultSet
interface ResultSet : Wrapper, AutoCloseable
java.sql.ResultSet |
A table of data representing a database result set, which is usually generated by executing a statement that queries the database.
A ResultSet
object maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The next
method moves the cursor to the next row, and because it returns false
when there are no more rows in the ResultSet
object, it can be used in a while
loop to iterate through the result set.
A default ResultSet
object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce ResultSet
objects that are scrollable and/or updatable. The following code fragment, in which con
is a valid Connection
object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See ResultSet
fields for other options.
Statement stmt = con.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE); ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2"); // rs will be scrollable, will not show changes made by others, // and will be updatableThe
ResultSet
interface provides getter methods (getBoolean
, getLong
, and so on) for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.
For the getter methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the getter method and returns a suitable Java value. The JDBC specification has a table showing the allowable mappings from SQL types to Java types that can be used by the ResultSet
getter methods.
Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQL AS clause.
A set of updater methods were added to this interface in the JDBC 2.0 API (JavaTM 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.
The updater methods may be used in two ways:
- to update a column value in the current row. In a scrollable
ResultSet
object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates theNAME
column in the fifth row of theResultSet
objectrs
and then uses the methodupdateRow
to update the data source table from whichrs
was derived.rs.absolute(5); // moves the cursor to the fifth row of rs rs.updateString("NAME", "AINSWORTH"); // updates the // <code>NAME</code>column of row 5 to be <code>AINSWORTH</code>rs.updateRow(); // updates the row in the data source
- to insert column values into the insert row. An updatable
ResultSet
object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it intors
and into the data source table using the methodinsertRow
.rs.moveToInsertRow(); // moves cursor to the insert row rs.updateString(1, "AINSWORTH"); // updates the // first column of the insert row to be <code>AINSWORTH</code>rs.updateInt(2,35); // updates the second column to be <code>35</code>rs.updateBoolean(3, true); // updates the third column to <code>true</code>rs.insertRow(); rs.moveToCurrentRow();
A ResultSet
object is automatically closed when the Statement
object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.
The number, types and properties of a ResultSet
object's columns are provided by the ResultSetMetaData
object returned by the ResultSet.getMetaData
method.

Public methods
absolute
abstract fun absolute(row: Int): Boolean
Moves the cursor to the given row number in this ResultSet
object.
If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.
If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method absolute(-1)
positions the cursor on the last row; calling the method absolute(-2)
moves the cursor to the next-to-last row, and so on.
If the row number specified is zero, the cursor is moved to before the first row.
An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.
Note: Calling absolute(1)
is the same as calling first()
. Calling absolute(-1)
is the same as calling last()
.
Parameters | |
---|---|
row |
Int: the number of the row to which the cursor should move. A value of zero indicates that the cursor will be positioned before the first row; a positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set |
Return | |
---|---|
Boolean |
true if the cursor is moved to a position in this ResultSet object; false if the cursor is before the first row or after the last row |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
afterLast
abstract fun afterLast(): Unit
Moves the cursor to the end of this ResultSet
object, just after the last row. This method has no effect if the result set contains no rows.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
beforeFirst
abstract fun beforeFirst(): Unit
Moves the cursor to the front of this ResultSet
object, just before the first row. This method has no effect if the result set contains no rows.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
cancelRowUpdates
abstract fun cancelRowUpdates(): Unit
Cancels the updates made to the current row in this ResultSet
object. This method may be called after calling an updater method(s) and before calling the method updateRow
to roll back the updates made to a row. If no updates have been made or updateRow
has already been called, this method has no effect.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set; the result set concurrency is CONCUR_READ_ONLY or if this method is called when the cursor is on the insert row |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
clearWarnings
abstract fun clearWarnings(): Unit
Clears all warnings reported on this ResultSet
object. After this method is called, the method getWarnings
returns null
until a new warning is reported for this ResultSet
object.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs or this method is called on a closed result set |
close
abstract fun close(): Unit
Releases this ResultSet
object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.
The closing of a ResultSet
object does not close the Blob
, Clob
or NClob
objects created by the ResultSet
. Blob
, Clob
or NClob
objects remain valid for at least the duration of the transaction in which they are creataed, unless their free
method is invoked.
When a ResultSet
is closed, any ResultSetMetaData
instances that were created by calling the getMetaData
method remain accessible.
Note: A ResultSet
object is automatically closed by the Statement
object that generated it when that Statement
object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.
Calling the method close
on a ResultSet
object that is already closed is a no-op.
Exceptions | |
---|---|
java.lang.Exception |
if this resource cannot be closed |
java.sql.SQLException |
if a database access error occurs |
deleteRow
abstract fun deleteRow(): Unit
Deletes the current row from this ResultSet
object and from the underlying database. This method cannot be called when the cursor is on the insert row.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; the result set concurrency is CONCUR_READ_ONLY ; this method is called on a closed result set or if this method is called when the cursor is on the insert row |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
findColumn
abstract fun findColumn(columnLabel: String!): Int
Maps the given ResultSet
column label to its ResultSet
column index.
Parameters | |

getObject
abstract fun getObject(columnIndex: Int): Any!
Gets the value of the designated column in the current row of this ResultSet
object as an Object
in the Java programming language.
This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL
, the driver returns a Java null
.
This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of method getObject
is extended to materialize data of SQL user-defined types.
If Connection.getTypeMap
does not throw a SQLFeatureNotSupportedException
, then when a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap())
. If Connection.getTypeMap
does throw a SQLFeatureNotSupportedException

isLast
abstract fun isLast(): Boolean
Retrieves whether the cursor is on the last row of this ResultSet
object. Note: Calling the method isLast
may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.
Note: Support for the isLast
method is optional for ResultSet
s with a result set type of TYPE_FORWARD_ONLY
Return | |
---|---|
Boolean |
true if the cursor is on the last row; false otherwise |

last
abstract fun last(): Boolean
Moves the cursor to the last row in this ResultSet
object.
Return | |
---|---|
Boolean |
true if the cursor is on a valid row; false if there are no rows in the result set |
Exceptions | |
---|---|

moveToCurrentRow
abstract fun moveToCurrentRow(): Unit
Moves the cursor to the remembered cursor position, usually the current row. This method has no effect if the cursor is not on the insert row.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set concurrency is CONCUR_READ_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
moveToInsertRow
abstract fun moveToInsertRow(): Unit
Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updater methods prior to inserting the row into the result set. Only the updater, getter, and insertRow
methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow
. An updater method must be called before a getter method can be called on a column value.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set concurrency is CONCUR_READ_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
next
abstract fun next(): Boolean
Moves the cursor froward one row from its current position. A ResultSet
cursor is initially positioned before the first row; the first call to the method next
makes the first row the current row; the second call makes the second row the current row, and so on.
When a call to the next
method returns false
, the cursor is positioned after the last row. Any invocation of a ResultSet
method which requires a current row will result in a SQLException
being thrown. If the result set type is TYPE_FORWARD_ONLY
, it is vendor specified whether their JDBC driver implementation will return false
or throw an SQLException
on a subsequent call to next
.
If an input stream is open for the current row, a call to the method next
will implicitly close it. A ResultSet
object's warning chain is cleared when a new row is read.
Return | |
---|---|
Boolean |
true if the new current row is valid; false if there are no more rows |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs or this method is called on a closed result set |
previous
abstract fun previous(): Boolean
Moves the cursor to the previous row in this ResultSet
object.
When a call to the previous
method returns false
, the cursor is positioned before the first row. Any invocation of a ResultSet
method which requires a current row will result in a SQLException
being thrown.
If an input stream is open for the current row, a call to the method previous
will implicitly close it. A ResultSet
object's warning change is cleared when a new row is read.
Return | |
---|---|
Boolean |
true if the cursor is now positioned on a valid row; false if the cursor is positioned before the first row |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
refreshRow
abstract fun refreshRow(): Unit
Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.
The refreshRow
method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow
when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.
All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow
is called after calling an updater method, but before calling the method updateRow
, then the updates made to the row are lost. Calling the method refreshRow
frequently will likely slow performance.
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set; the result set type is TYPE_FORWARD_ONLY or if this method is called when the cursor is on the insert row |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method or this method is not supported for the specified result set type and result set concurrency. |
relative
abstract fun relative(rows: Int): Boolean
Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling relative(0)
is valid, but does not change the cursor position.
Note: Calling the method relative(1)
is identical to calling the method next()
and calling the method relative(-1)
is identical to calling the method previous()
.
Parameters | |
---|---|
rows |
Int: an int specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward |
Return | |
---|---|
Boolean |
true if the cursor is on a row; false otherwise |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
rowDeleted
abstract fun rowDeleted(): Boolean
Retrieves whether a row has been deleted. A deleted row may leave a visible "hole" in a result set. This method can be used to detect holes in a result set. The value returned depends on whether or not this ResultSet
object can detect deletions.
Note: Support for the rowDeleted
method is optional with a result set concurrency of CONCUR_READ_ONLY
Return | |
---|---|
Boolean |
true if the current row is detected to have been deleted by the owner or another; false otherwise |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs or this method is called on a closed result set |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
rowInserted
abstract fun rowInserted(): Boolean
Retrieves whether the current row has had an insertion. The value returned depends on whether or not this ResultSet
object can detect visible inserts.
Note: Support for the rowInserted
method is optional with a result set concurrency of CONCUR_READ_ONLY
Return | |
---|---|
Boolean |
true if the current row is detected to have been inserted; false otherwise |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs or this method is called on a closed result set |
java.sql.SQLFeatureNotSupportedException |
if the JDBC driver does not support this method |
rowUpdated
abstract fun rowUpdated(): Boolean
Retrieves whether the current row has been updated. The value returned depends on whether or not the result set can detect updates.
Note: Support for the rowUpdated
method is optional with a result set concurrency of CONCUR_READ_ONLY
Return | |
---|---|
Boolean |
true if the current row is detected to have been visibly updated by the owner or another; false otherwise |
Exceptions | |
---|---|

Int: an int specifying the suggested fetch direction; one of ResultSet.FETCH_FORWARD , ResultSet.FETCH_REVERSE , or ResultSet.FETCH_UNKNOWN |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY and the fetch direction is not FETCH_FORWARD |
setFetchSize
abstract fun setFetchSize(rows: Int): Unit
Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for this ResultSet
object. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. The default value is set by the Statement
object that created the result set. The fetch size may be changed at any time.
Parameters | |
---|---|
rows |
Int: the number of rows to fetch |
Exceptions | |
---|---|
java.sql.SQLException |
if a database access error occurs; this method is called on a closed result set or the condition rows >= 0 is not satisfied |
