- If you want to do multiple COUNT(), in multiple tables, and output them in a single SELECT statement with each COUNT being a column; you can use a SQL query like this:

Code: Select all

SELECT
  (SELECT COUNT(*) FROM table_1 WHERE some_condition) AS nrc1,
  (SELECT COUNT(*) FROM table_1 WHERE other_condition) AS nrc2,
  (SELECT COUNT(*) FROM table_2 WHERE some_condition) AS nrc3
FROM table_1 LIMIT 1

- Outputs:

Code: Select all

nrc1 | nrc2 | nrc3
 123 |  78  | 589
