SQLiteQueryBuilder

Kotlin |Java

public class SQLiteQueryBuilder
extends Object

java.lang.Object
↳	android.database.sqlite.SQLiteQueryBuilder

This is a convenience class that helps build SQL queries to be sent to SQLiteDatabase objects.

This class is often used to compose a SQL query from client-supplied fragments. Best practice to protect against invalid or illegal SQL is to set the following:

setStrict(boolean) true.
setProjectionMap(Map) with the list of queryable columns.
setStrictColumns(boolean) true.
setStrictGrammar(boolean) true.

appendWhere

Added in API level 1

public void appendWhere (CharSequence inWhere)

Append a chunk to the WHERE clause of the query. All chunks appended are surrounded by parenthesis and ANDed with the selection passed to query(SQLiteDatabase, String, String, String, String, String, String). The final WHERE clause looks like:

WHERE (<append chunk 1><append chunk2>) AND (<query() selection parameter>)

Parameters
`inWhere`	`CharSequence`: the chunk of text to append to the `WHERE` clause. This value cannot be `null`.

appendWhereEscapeString

Added in API level 1

public void appendWhereEscapeString (String inWhere)

Append a chunk to the WHERE clause of the query. All chunks appended are surrounded by parenthesis and ANDed with the selection passed to query(SQLiteDatabase, String, String, String, String, String, String). The final WHERE clause looks like:

WHERE (<append chunk 1><append chunk2>) AND (<query() selection parameter>)

Parameters
`inWhere`	`String`: the chunk of text to append to the `WHERE` clause. it will be escaped to avoid SQL injection attacks This value cannot be `null`.

appendWhereStandalone

Added in API level 29

public void appendWhereStandalone (CharSequence inWhere)

Add a standalone chunk to the WHERE clause of this query.

This method differs from appendWhere(java.lang.CharSequence) in that it automatically appends AND to any existing WHERE clause already under construction before appending the given standalone expression wrapped in parentheses.

Parameters
`inWhere`	`CharSequence`: the standalone expression to append to the `WHERE` clause. It will be wrapped in parentheses when it's appended. This value cannot be `null`.

Construct a SELECT statement suitable for use in a group of SELECT statements that will be joined through UNION operators in buildUnionQuery.

Parameters
`typeDiscriminatorColumn`	`String`: the name of the result column whose cells will contain the name of the table from which each row was drawn.
`unionColumns`	`String`: the names of the columns to appear in the result. This may include columns that do not appear in the table this `SELECT` is querying (i.e. mTables), but that do appear in one of the other tables in the `UNION` query that we are constructing.
`columnsPresentInTable`	`Set`: a Set of the names of the columns that appear in this table (i.e. in the table whose name is mTables). Since columns in unionColumns include columns that appear only in other tables, we use this array to distinguish which ones actually are present. Other columns will have NULL values for results from this subquery.
`computedColumnsOffset`	`int`: all columns in unionColumns before this index are included under the assumption that they're computed and therefore won't appear in columnsPresentInTable, e.g. "date * 1000 as normalized_date"

setCursorFactory

Added in API level 1

public void setCursorFactory (SQLiteDatabase.CursorFactory factory)

Sets the cursor factory to be used for the query. You can use one factory for all queries on a database but it is normally easier to specify the factory when doing this query.

Parameters
`factory`	`SQLiteDatabase.CursorFactory`: the factory to use. This value may be `null`.

setDistinct

Added in API level 1

public void setDistinct (boolean distinct)

Mark the query as DISTINCT.

Parameters
`distinct`	`boolean`: if true the query is `DISTINCT`, otherwise it isn't

setProjectionGreylist

Added in API level 30

public void setProjectionGreylist (Collection<Pattern> projectionGreylist)

Sets a projection greylist of columns that will be allowed through, even when setStrict(boolean) is enabled. This provides a way for abusive custom columns like COUNT(*) to continue working.

Parameters
`projectionGreylist`	`Collection`: This value may be `null`.

setProjectionMap

Added in API level 1

public void setProjectionMap (Map<String, String> columnMap)

Sets the projection map for the query. The projection map maps from column names that the caller passes into query to database column names. This is useful for renaming columns as well as disambiguating column names when doing joins. For example you could map "name" to "people.name". If a projection map is set it must contain all column names the user may request, even if the key and value are the same.

Parameters
`columnMap`	`Map`: maps from the user column names to the database column names This value may be `null`.

setStrict

Added in API level 14

public void setStrict (boolean strict)

When set, the selection is verified against malicious arguments. When using this class to create a statement using buildQueryString(boolean, java.lang.String, java.lang.String[], java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String), non-numeric limits will raise an exception. If a projection map is specified, fields not in that map will be ignored. If this class is used to execute the statement directly using query(android.database.sqlite.SQLiteDatabase, java.lang.String[], java.lang.String, java.lang.String[], java.lang.String, java.lang.String, java.lang.String) or query(android.database.sqlite.SQLiteDatabase, java.lang.String[], java.lang.String, java.lang.String[], java.lang.String, java.lang.String, java.lang.String, java.lang.String), additionally also parenthesis escaping selection are caught. To summarize: To get maximum protection against malicious third party apps (for example content provider consumers), make sure to do the following:

Set this value to true
Use a projection map
Use one of the query overloads instead of getting the statement as a sql string

This feature is disabled by default on each newly constructed SQLiteQueryBuilder and needs to be manually enabled.

Parameters
`strict`	`boolean`

setStrictColumns

Added in API level 30

public void setStrictColumns (boolean strictColumns)

When enabled, verify that all projections and ContentValues only contain valid columns as defined by setProjectionMap(java.util.Map).

This enforcement applies to insert(SQLiteDatabase, ContentValues), query(SQLiteDatabase, String, String, String, String, String, String), and update(SQLiteDatabase, ContentValues, String, String) operations. Any enforcement failures will throw an IllegalArgumentException.

This feature is disabled by default on each newly constructed SQLiteQueryBuilder and needs to be manually enabled.

Parameters
`strictColumns`	`boolean`

setStrictGrammar

Added in API level 30

public void setStrictGrammar (boolean strictGrammar)

When enabled, verify that all untrusted SQL conforms to a restricted SQL grammar. Here are the restrictions applied:

In WHERE and HAVING clauses: subqueries, raising, and windowing terms are rejected.
In GROUP BY clauses: only valid columns are allowed.
In ORDER BY clauses: only valid columns, collation, and ordering terms are allowed.
In LIMIT clauses: only numerical values and offset terms are allowed.

All column references must be valid as defined by setProjectionMap(java.util.Map).

This enforcement applies to query(SQLiteDatabase, String, String, String, String, String, String), update(SQLiteDatabase, ContentValues, String, String) and delete(SQLiteDatabase, String, String) operations. This enforcement does not apply to trusted inputs, such as those provided by appendWhere(CharSequence). Any enforcement failures will throw an IllegalArgumentException.

This feature is disabled by default on each newly constructed SQLiteQueryBuilder and needs to be manually enabled.

Parameters
`strictGrammar`	`boolean`

setTables

Added in API level 1

public void setTables (String inTables)

Sets the list of tables to query. Multiple tables can be specified to perform a join. For example: setTables("foo, bar") setTables("foo LEFT OUTER JOIN bar ON (foo.id = bar.foo_id)")

Parameters
`inTables`	`String`: the list of tables to query on This value may be `null`.

update

Added in API level 29

public int update (SQLiteDatabase db, 
                ContentValues values, 
                String selection, 
                String[] selectionArgs)

Perform an update by combining all current settings and the information passed into this method.

Parameters
`db`	`SQLiteDatabase`: the database to update on This value cannot be `null`.
`values`	`ContentValues`: This value cannot be `null`.
`selection`	`String`: A filter declaring which rows to return, formatted as an SQL `WHERE` clause (excluding the `WHERE` itself). Passing null will return all rows for the given URL.
`selectionArgs`	`String`: You may include ?s in selection, which will be replaced by the values from selectionArgs, in order that they appear in the selection. The values will be bound as Strings. This value may be `null`.

Returns
`int`	the number of rows updated
