Re: BUG #18774: Not the required output of the query used in the function(delete_from_table1) in postgresql9.4

Hello Sir,

Thanks for the reply,

as per the documentation, following query execute successfully :

EXECUTE 'SELECT count(*) FROM '
|| quote_ident(tabname)
|| ' WHERE inserted_by = $1 AND inserted <= $2'
INTO c
USING checked_user, checked_date;

HERE, $1 and $2 are strings and its values are substituted in the
query. Please clarify, may be i am missing something.

Regards,

Rajni Bobal
