Azure Synapse SQL does not support the the use of TABLE variable. Therefore a workaround is to use Temporary Tables in SqlDW. If we run the below statement in Synapse SQL then it willa throw syntax error as below:
/*Standard use on TABLE Variable*/
DECLARE @tblExclude TABLE ([ColumnName] sysname NOT NULL);
Msg 103010, Level 16, State 1, Line 1
Parse error at line: 1, column: 21: Incorrect syntax near 'T
Alternative solution to achive the same goal as Table Variable in SqlDW / Synapse SQL is to use temp tables as below:
IF OBJECT_ID('tempdb..#tblExclude') IS NOT NULL
DROP TABLE #tblExclude
CREATE TABLE #tblExclude ([ColumnName] SYSNAME NOT NULL)
