if you have more than one pnid, you should use perl or php. then use a loop to
manage each pnid query, then send it to the server, and use it's result.
another simpler solution :
mysql> create table sql as select concat('vt_',pnid) tbl from vt_parition where
pnid regexp ('^[0-9]{

Many thanks to everybody who tried to help me!

I need to do the following:
Get one or more than one "pnid" from vt_partition and then make queries to the
"vt_pni
Hello,
You forgot a parenthesis in the regexp function.
Second, if you construct your query with prepared statements, you can do it :

mysql> select concat('vt_',pnid) into @tbl from vt_parition where pnid regexp
('^[0-9]{11}$') ;
mysql>

Have you looked at this page of the manual?
http://dev.mysql.com/doc/mysql/en/string-comparison-functions.html

You might find that LIKE or STRCMP() work better than REGEXP for your
requirements.
