Hi,
I am running the below query. Table has 21 million records. I get an Out Of
Memory error after a while.(from both pgadmin and psql). Can someone review DB
parameters given below.
select t.*,g.column,a.column from
gk_staging g, transaction t,account a
where
g.accountcodeis not null AND
g.accountcode::text <> '' AND
length(g.accountcode)=13 AND
g.closeid::text=t.transactionid::text AND
subsrting(g.accountcode::text,8)=a.mask_code::text
Below are system parameters.
shared_buffers=3GB
work_mem=2GB
effective_cache_size=10GB
maintenance_work_mem=1GB
max_connections=250
I am unable to paste explain plan here due to security concerns.
You have not provided schema, explain-output nor the error-message.
Without this it's pretty much guess-work...
