Error: column "host" does not exist
Hello,
I am working with 8.1.4 pgsql as my database backend. I have a function
written in plpgsql language, that queries a particular table as below,
select host from table_host where ip_address = ip_array[i] and port =
port_array[i];
The query is running in a for loop. I see ip_array and port_array
getting populated with correct values during the execution.
The error I see is,
ERROR: column "host" does not exist
CONTEXT: SQL statement "SELECT host"
PL/pgSQL function "sp_get_ip_data" line 286 at raise
throu psql, I can select the table_host fine.
column "host" is a primary key here.
I dont understand why I see the "column does not exist" error; any idea ?
cheers
Mayuresh
IS there any name clash with a function argument?

Not sure, but host is a reserved word, see:

No. there are no name clashes.
I actually changed the names in posted text a bit. The arguments,
declared variables and column names, all have their unique prefixes.
Thanks

Please post is possible the code (DDL and function).
Otherwise it'd be much more difficult.
And if you change the names, please check whether the error is still there.

That list says that HOST is reserved in SQL:1999, but not in PostgreSQL.
