- Parameters:

-- Throws:

Method Detail
-
getNewDocument
public static SQLDocument getNewDocument(ExpressionContext exprContext)
This static method simplifies the creation of an SQL Document and allows us to embedd the complexity of creating / handling the dtmIdent inside the document. This type of method may better placed inside the DTMDocument code
-
getExpressionContext
public ExpressionContext getExpressionContext()
Return the context used to build this document
-
execute
public void execute(XConnection xconn, SQLQueryParser query) throws java.sql.SQLException
- Throws:
java.sql.SQLException
-
skip
public void skip(int value)
Push the record set forward value rows. Used to help in SQL pagination.- Parameters:
value
-
-
hasErrors
public boolean hasErrors()
Used by the XConnection to determine if the Document should handle the document differently.
-
close
public void close(boolean flushConnPool)
Close down any resources used by this document. If an SQL Error occure while the document was being accessed, the SQL Connection used to create this document will be released to the Connection Pool on error. This allows the COnnection Pool to give special attention to any connection that may be in a errored state.
-
documentRegistration
public void documentRegistration()
Description copied from class:DTMDefaultBase
A dummy routine to satisify the abstract interface. If the DTM implememtation that extends the default base requires notification of registration, they can override this method.- Specified by:
documentRegistration
in interfaceDTM
- Overrides:
documentRegistration
in classDTMDefaultBase
-
documentRelease
public void documentRelease()
Description copied from class:DTMDefaultBase
A dummy routine to satisify the abstract interface. If the DTM implememtation that extends the default base requires notification when the document is being released, they can override this method- Specified by:
documentRelease
in interfaceDTM
- Overrides:
documentRelease
in classDTMDefaultBase
-
checkWarnings
public java.sql.SQLWarning checkWarnings()
