BREAK exits the current WHILE loop. If the current WHILE loop is nested inside another, BREAK exits only the current loop, and control is given to the next statement in the outer loop.
BREAK is usually inside an IF statement.
Examples
Example for SQL Server
Imagine a table where a value is expected when another antecedent process is completed:
WHILE (1=1)
BEGIN
IF EXISTS (SELECT*FROM##MyTempTable WHERE EventCode = 'Done')BEGIN
BREAK; -- 'Done' row has finally been inserted and detected, so end this loop.
END
PRINT N'The other process is not yet done.'; -- Re-confirm the non-done status to the console.
WAITFOR DELAY '00:01:30'; -- Sleep for 90 seconds.
END
Example for Azure Synapse dedicated SQL pool
DECLARE @sleeptimesec int=1;
DECLARE @startingtime datetime2(2) = getdate();
PRINT N'Sleeping for '+ CAST(@sleeptimesec asvarchar(5)) +' seconds'
WHILE (1=1)
BEGIN
PRINT N'Sleeping.';
PRINT datediff(s, getdate(), @startingtime)
IF datediff(s, getdate(), @startingtime) <-@sleeptimesec
BEGIN
PRINT 'We have finished waiting.';
BREAK;
END
