Hello,

i would like to know if this is correct or wrong my if loop condition is as follows
IF Student IS NULL AND is_error IS NULL THEN
where Student and is_error is char(20) Data type. the above condition is not true or is it true.

Thanks

"IF" checks for a condition - it is not a loop. Maybe you want to have a loop, look at the FOR, WHILE, and LOOP statements.

Other than that, I don't understand your question. Syntactically, the condition is correct - you are only missing the code in the THEN branch and an END IF.
