Question

Can you please guide me to the equivalent to this query in Oracle:

SELECT SQL_CALC_FOUND_ROWS * FROM tableName 

SELECT FOUND_ROWS() as cnt

Thanks

Answer 1

The query retrieves all rows from tableName, and then retrieves the number of rows in tableName. Doing that with SQL_CALC_FOUND_ROWS is just a performance optimization: it saves you from doing two queries.

If performance is not an issue, an equivalent for Oracle would be:

SELECT * FROM tableName 
SELECT count(*) from tableName

If you are in a position to rewrite the client, you could do both in one query:

SELECT  *
,       (SELECT count(*) from tableName) as totalRows
FROM    tableName
