Question

I’ve a SP that contains multiple update and insert queries. If any of the query gives the error, does execution move to next statement? For example,

CREATE PROCEDURE Test()
AS
BEGIN
    INSERT INTO SomeTable VALUES (1, 2, 3)
    UPDATE SomeTable SET X = 4 WHERE Y = 5
END

In above example, if INSERT statement throws the error, would execution move to next UPDATE statement?

Answer 1

It depends on the error severity. From severity 19 and up, the batch gets aborted:

Indicates that a nonconfigurable Database Engine limit has been
exceeded and the current batch process has been terminated. Error
messages with a severity level of 19 or higher stop the execution of
the current batch.

However note that if the code above runs within a BEGIN TRY/BEGIN CATCH block (or is called from such a block) then errors with severity 10-18 cause the control flow to jump to the catch block (which is not the same as saying that the execution got aborted) and thus the next statement will not be executed.

In addition the XACT_ABORT setting also causes the current transaction to rollback and the current batch to abort.
