Hi Sim
 
Thanks for your response. I had it working from a previous post by Adam Tomjack.
<snip>

-- A list of tables:

SELECT schemaname, tablename FROM pg_tables;

-- Returns true if a table exists:

SELECT count(*)>0 FROM pg_tables

WHERE schemaname='...' AND tablename='...'

</snip>
 
 
Your response does not work for me. Perhaps you can explain the posted command
 
<snip>
* from pg_class where relkind='r' and relname=your_tablename
</snip>

Hi

Hate to ask, but it isnt obvious to me from the documentation.
How do I perform a query in pgplsql, to check it a table exists of a particular name.

Thanks in advance

Kind Regards,
Shaun Clements
