Hi All,
I am inserting a value into a table, Before inserting i am checking that record already exists or not in the target table, If its existsing i am making an entry into errorlog table and set the output parameter to 'errorlog' . This is inside the cursor, as il be passing multiple values. Next is I have separate query to get the new record which is not in the target table. Using EXCEPT i get the new record and i insert into a main table. after insertion i set output as 'success'.
Here while executing the procedure i pass a duplicate value and a new value. As it is in cursor,first it will insert into errorlog and set output parameter as 'errorlog' .Next it will insert a new record into main table and set output parameter as 'Success'. So on completion of the execution of the procedure i get output as success.
But i should get as errorlog. I should get success only on no errors in the procedure. How i can i achieve this? Please help me.
Below is my code
IF NOT EXISTS(SELECT Beginmilepost,BeginTrackName,Endmilepost,EndTrackName
