Error: relation with OID 22938 does not exist

[Shree111]

I am having some problems understanding how the temp tables work in PG. I have a relatively lengthy function I am creating that makes frequent use of temporary tables.

I am dropping and recreating the temp tables on each run. If I run the procedure the first time via psql it seems to run fine. If I try to immediately run it again I get the following message:

Error: relation with OID 22938 does not exist

The query it is running is the following:

Select Into sTableName TableName From tmp_tblJoin Where ID = 1;

Nothing special about it other than "tmp_tblJoi n" is defined as a temporary table.

I do understand what is happening (I think). There is a stale pointer to the previous instance of the temp table (that no longer exists) which is causing the function to blow up. My question is how to I stop it from storing the OID of the old reference.

plz help me out.........

Maybe try to define a variable a set it to temporary table name. Then execute a dynamic query using your variable as table name. Understand?

i have done according to ur suggestion....b ut identifier is going to be truncated.

declare

stmt text:="(i have written query here)";

begin

execute stmt;

end;

it is going to be splitting that declared query.......

whats the solution for this????
