Post your question to a community of 469,923 developers. It's quick & easy.

Insert ... Select...

I am new to mysql and would appreciate someone helping me out with this
converting this statement from postgresql to mysql.

INSERT INTO ossurjoinquestions SELECT *, RANDOM() as random_sort,
trunc(1144355460, 0) as instanceid FROM ossurcommonquestions WHERE tid =
'3';

So far I have

INSERT INTO ossurjoinquestions( tid, question, ans1, ans2, ans3, ans4, ans5,
corans, image_path, random_sort, instanceid )
SELECT tid, question, ans1, ans2, ans3, ans4, ans5, corans, image_path
FROM ossurcommonquestions
WHERE tid = '3'

What I am not sure how to do is add RAND() as random_sort or trunc($var,0)
as instanceid.

Thank you for any help.

RAND() is the MySQL equivalent of PostgreSQL's RANDOM() function.
TRUNCATE() is the MySQL equivalent of PostgreSQL's TRUNC() function.

See the documentation on the respective web sites:
http://www.postgresql.org/docs/8.1/i...ions-math.html
http://dev.mysql.com/doc/refman/5.0/...functions.html
