EXECUTE of a 'create table' string is not happening

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm passing a tablename and two columnnames into a function so that I can SELECT Records in a FOR LOOP using 'fixed' field names.
Using the passed params I construct the create table command and then alter the names of two columns.

When I 'build' the function and then run my query to use the function w/ a different offset it works the first time.
The first time ONLY.  But actually it doesn't work, it just doesn't error the first run.
Subsequent runs tell me that relation ######## doesn't exist, at the FOR...LOOP line, after ALTERing the table.

I build the string and it's good:
CREATE TABLE temp_gentokenstable AS SELECT businessid, publicname FROM businesscontact ORDER BY businessid OFFSET 200000 LIMIT 10000 ;

I'm forced to use v7.4.

If this is a known error, can I (with the version  ; ^)  ) get around it?

Ultimately I need to FOR..LOOP through through records and the table and cols will change.  Any suggestions???

THANKS!
