Method Detail

setSource

public void setSource(java.lang.String txt)

set the statement text

getConstantAction

public ConstantAction getConstantAction()

Get the Execution constants. This routine is called at Execution time.

getSavedObject

public java.lang.Object getSavedObject(int objectNum)

Get a saved object by number. This is called during execution to access objects created at compile time. These are meant to be read-only at run time.

getSavedObjects

public java.lang.Object[] getSavedObjects()

Get all the saved objects. Used for stored prepared statements.

getCursorInfo

public java.lang.Object getCursorInfo()

Get the saved cursor info. Used for stored prepared statements.

getActivationClass

public org.apache.derby.iapi.services.loader.GeneratedClass getActivationClass()
                                                                        throws org.apache.derby.iapi.error.StandardException

Get the class generated for this prepared statement. Used to confirm compatability with auxilary structures.

finish

public void finish(org.apache.derby.iapi.sql.conn.LanguageConnectionContext lcc)

Mark the statement as unusable, i.e. the system is finished with it and no one should be able to use it.

needsSavepoint

public boolean needsSavepoint()

Does this statement need a savpoint

getClone

public ExecPreparedStatement getClone()
                               throws org.apache.derby.iapi.error.StandardException

public int getUpdateMode()

the update mode of the cursor

getTargetTable

public ExecCursorTableReference getTargetTable()

the target table of the cursor

getTargetColumns

public org.apache.derby.iapi.sql.ResultColumnDescriptor[] getTargetColumns()
