public class TExitStmt
extends TCustomSqlStatement

The EXIT statement exits a loop and transfers control to the end of the loop. The EXIT statement has two forms: the unconditional EXIT and the conditional EXIT WHEN.

Method Details

setExitlabelName

public void setExitlabelName(TObjectName exitlabelName)

getExitlabelName

public TObjectName getExitlabelName()

getWhenCondition

public TExpression getWhenCondition()
