Constructor Detail

NotProcessResultJPAQueryCallback

public NotProcessResultJPAQueryCallback(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 NotProcessResultJPAQueryCallback.setCountRecordsQueryStatement(java.lang.String) (in this case, it will be ignored).

NotProcessResultJPAQueryCallback

public NotProcessResultJPAQueryCallback(java.lang.String queryStmt,
                                        java.lang.String countArgument,
                                        java.lang.String orderBy)

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

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 NotProcessResultJPAQueryCallback.setCountRecordsQueryStatement(java.lang.String) (in this case, it will be ignored).

orderBy - column that will be added to the 'ORDER BY' clause of JP QL query statement

NotProcessResultJPAQueryCallback

public NotProcessResultJPAQueryCallback(java.lang.String queryStmt,
                                        java.lang.String countArgument,
                                        java.lang.String orderBy,
                                        boolean ascending)

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

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.

orderBy - column that will be added to the 'ORDER BY' clause of JP QL query statement

ascending - if sorted by ascending order
