Oracle Query: Two/Multiple simple IF condition blocks in the same SQL file not executing

Question

The SQL file contains Two simple IF conditions, but it is not executing in TOAD:

IF (SELECT COUNT(COLUMNNAME1) FROM TABLENAME1 WHERE COLUMNNAME1 = 'UNIQUEID1') > 0)
BEGIN
(UPDATE QUERY1)
END;

IF (SELECT COUNT(COLUMNNAME1) FROM TABLENAME1 WHERE COLUMNNAME1 = 'UNIQUEID2') > 0)
BEGIN
(UPDATE QUERY2)
END;

But these are individually executing successfully, please let me know if the query is missing something.

Executed successfully and IF condition passes to update the table in the database

Answer 1

Should be more like this:

BEGIN        
    IF (SELECT COUNT(COLUMNNAME1) FROM TABLENAME1 
         WHERE COLUMNNAME1 = 'UNIQUEID1') > 0 THEN
        UPDATE QUERY1;
    END IF;

    IF (SELECT COUNT(COLUMNNAME1) FROM TABLENAME1 
         WHERE COLUMNNAME1 = 'UNIQUEID2') > 0 THEN
        UPDATE QUERY2;
    END IF;
END;

You may want to commit your changes somewhere in this script, too.
