Method Detail

activationKind

int activationKind()

Specified by:

activationKind in class StatementNode

isAtomic

public boolean isAtomic()

COMMIT and ROLLBACK are allowed to commit and rollback, duh.

Overrides:

isAtomic in class StatementNode

Returns:

false

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 StatementNode

Returns:

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