Method Detail

activationKind

int activationKind()

Specified by:

activationKind in class StatementNode

generate

public void generate(ActivationClassBuilder acb,
                     MethodBuilder mb)
              throws StandardException

Generic generate code for all Misc statements that need activations.

Overrides:

generate in class QueryTreeNode

Parameters:

acb - The ActivationClassBuilder for the class being built

mb - the method for the execute() method to be built

Returns:

A compiled expression returning the RepCreatePublicationResultSet

Throws:

StandardException - Thrown on error

needsSavepoint

public boolean needsSavepoint()

Returns whether or not this Statement requires a set/clear savepoint around its execution. The following statement "types" do not require them: Cursor - unnecessary and won't work in a read only environment Xact - savepoint will get blown away underneath us during commit/rollback

Overrides:

needsSavepoint in class QueryTreeNode

Returns:

boolean Whether or not this Statement requires a set/clear savepoint
