execute

@Beta
default Result execute(CqnSelect select,
                       Iterable<Map<String,Object>> valueSets)

Executes a CqnSelect statement as batch with the given named parameter values. Named parameters are required either in the where clause, or in one infix filter of the from clause. If the number of entries in valueSets is larger than the default batch size, the select statement is executed multiple times and the result sets are combined, in this case order by clauses are not supported and an exception is thrown.

Parameters:

select - the CQN select statement to be executed

valueSets - the named parameter value sets

Returns:

the Result of the batch select

execute

@Beta
Result execute(CqnSelect select,
               Iterable<Map<String,Object>> valueSets,
               int maxBatchSize)

Executes a CqnSelect statement as batch with the given named parameter values. Named parameters are required either in the where clause, or in one infix filter of the from clause. If the number of entries in valueSets is larger than maxBatchSize, the select statement is executed multiple times and the result sets are combined, in this case order by clauses are not supported and an exception is thrown.

Parameters:

select - the CQN select statement to be executed

valueSets - the named parameter value sets

maxBatchSize - the maximum batch size

Returns:

the Result of the batch select

execute
