Interface DeleteQuery<R extends Record>

Type Parameters:

R - The record type of the table being deleted from

All Superinterfaces:

Attachable, AttachableQueryPart, AutoCloseable, ConditionProvider, Delete<R>, Flow.Publisher<Integer>, Publisher<Integer>, org.reactivestreams.Publisher<Integer>, Query, QueryPart, RowCountQuery, Serializable, Statement

public interface DeleteQuery<R extends Record>
extends ConditionProvider, Delete<R>

A DELETE statement (model API).

This type is the model API representation of a Delete statement, which can be mutated after creation. The advantage of this API compared to the DSL API is a more simple approach to writing dynamic SQL.

Instances can be created using DSLContext.deleteQuery(Table).

setReturning

@Support({AURORA_POSTGRES,COCKROACHDB,DB2,FIREBIRD,MARIADB_10_1,ORACLE,POSTGRES})
void setReturning()

See Also:

getReturnedRecords()

getReturnedRecord

@Nullable
@Support({AURORA_POSTGRES,COCKROACHDB,DB2,FIREBIRD,MARIADB_10_1,ORACLE,POSTGRES})
R getReturnedRecord()

The record holding returned values as specified by any of the setReturning() methods.

If the DELETE statement returns several records, this is the same as calling getReturnedRecords().get(0)

This implemented differently for every dialect:

• Firebird and Postgres have native support for DELETE .. RETURNING clauses

Returns:

The returned value as specified by any of the setReturning() methods. This may return null in case jOOQ could not retrieve any generated keys from the JDBC driver.

See Also:

getReturnedRecords()

getReturnedRecords

@NotNull
@Support({AURORA_POSTGRES,COCKROACHDB,DB2,FIREBIRD,MARIADB_10_1,ORACLE,POSTGRES})
@NotNull Result<R> getReturnedRecords()

The records holding returned values as specified by any of the setReturning() methods.

If the DELETE statement returns several records, this is the same as calling getReturnedRecords().get(0)

This implemented differently for every dialect:

• Firebird and Postgres have native support for DELETE .. RETURNING clauses

Returns:

The returned values as specified by any of the setReturning() methods. Note:

• Not all databases / JDBC drivers support returning several values on multi-row inserts!
• This may return an empty Result in case jOOQ could not retrieve any generated keys from the JDBC driver.
