DefaultJPAQueryCallback

public DefaultJPAQueryCallback(java.lang.String queryStmt,
                               java.lang.String countArgument)

Please note, since version 1.3.2, this construct adds another argument countArgument to fix a design defect not complying with the JPA specification. So if you upgrade from previous versions, you may find a compilation error.

Parameters:

queryStmt - JP QL (Java Persistence Query Language) query statement

countArgument - to query the total number of records, the "SELECT COUNT([countArgument]) FROM ..." statement (generated based on the query statement) needs to be executed. As specified by JPA Specification, the COUNT function takes either an identification variable or a path expression as its argument. This argument will be used as the COUNT function's argument. This argument can not be null or empty, unless the property countRecordsQueryStatement is set explicitly by calling the method DefaultJPAQueryCallback.setCountRecordsQueryStatement(java.lang.String) (in this case, it will be ignored).
