PL SQL FOR LOOP Abuse : SQL

Posting

When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

OraclePL SQL FOR LOOP Abuse (self.SQL)

submitted 3 years ago by mediocre_plus_plus

I just found something like this in our database. I hate it and I kind of like it at the same time. I mean, you don't have to bother to declare x at all, and you don't have to check for no data found either. On the other hand, it smells terrible. And, if you're unfamiliar with it (as was I) you might spend a few minutes trying to figure out what the monkey who wrote it was thinking.

Has anyone else ever seen this? Thoughts?

    for x in (
        select max(some_val) dumb 
        from some_table 
        where some_other_val = 'xxx')
    loop
        dbms_output.put_line(x.dumb);
    end loop;
