countRowsStmt -

getQueryStatement

public java.lang.String getQueryStatement()

Description copied from interface: QueryCallback

Query statement(e.g. sql for JDBC and queryString for Hibernate)

Specified by:

getQueryStatement in interface QueryCallback

Returns:

getCountRecordsQueryStatement

public java.lang.String getCountRecordsQueryStatement()

Description copied from interface: QueryCallback

Query statement to count total records. If this property is not provided, the corresponding QueryTemplate will do some auto translation to generate the "count query statement" based on "queryStatement" property and related persistence technology or database provides (e.g. the way of translation is different between Hibernate and JDBC, Oracle and DB2).

public QueryOrder getQueryOrder()

Description copied from interface: QueryCallback

Order information used by query statement

Specified by:

getQueryOrder in interface QueryCallback

Returns:

setQueryOrder

public void setQueryOrder(QueryOrder aOrder)

Description copied from interface: QueryCallback

Set order information used by query statement

Specified by:

setQueryOrder in interface QueryCallback
