@Support SelectForUpdateStep<R> limit(int numberOfRows)
LIMIT
clause to the query.
If there is no LIMIT
or TOP
clause in your
RDBMS, this may be simulated with a ROW_NUMBER()
window
function and nested SELECT
statements.
@Support(value={CUBRID,DB2,DERBY,FIREBIRD,H2,HSQLDB,MARIADB,MYSQL,ORACLE,POSTGRES,SQLITE,SQLSERVER,SYBASE}) SelectForUpdateStep<R> limit(Param<Integer> numberOfRows)
LIMIT
clause to the query using named parameters.
Note that some dialects do not support bind values at all in
LIMIT
or TOP
clauses!
If there is no LIMIT
or TOP
clause in your
RDBMS, or the LIMIT
or TOP
clause does not
support bind values, this may be simulated with a
ROW_NUMBER()
window function and nested SELECT
statements.
