Hi, Is this what you are trying to do? postgres=# select * from (select count(*) from people ) p, (select firstname from people)p2; count | firstname -------+----------- 5 | Mary 5 | Mary 5 | John 5 | John 5 | Jacob (5 rows) I do not know about the performance impact of such a query (cartesian join) Regards, Jayadevan
From: "Snyder, James" <jsnyd...@harris.com> To: <pgsql-sql@postgresql.org> Date: 26/03/2010 03:21 Subject: [SQL] SQL syntax rowcount value as an extra column in the result set Sent by: pgsql-sql-ow...@postgresql.org Hello I’m using PostgreSQL (8.4.701) and Java (jdbc, postgresql-8.4-701.jdbc4.jar) to connect to the database. My question is: what is the SQL syntax for PostgreSQL to achieve the following: I want to receive the rowcount along with the rest of a result set. For example, let’s say the following query returns select first_name from people; first_name ========= Mary Sue Joe and the following query returns the value select count(*)as ROWCOUNT from people; ROWCOUNT ========== 3 3 What I’m looking for is the output as ROWCOUNT , first_name ===================== 3 , Mary 3 , Sue 3 , Joe so I can use JDBC (snip-it) as follows: resultSet.getInt(“ROWCOUNT”) resultSet.getString(“first_name”) On a side note, Oracle allows the following syntax to achieve the above: select count(*) over () as ROWCOUNT , first_name from people Thanks,Jim DISCLAIMER: "The information in this e-mail and any attachment is intended only for the person to whom it is addressed and may contain confidential and/or privileged material.
