Question

I have two tables in my MySQL database (table1 and table 2). I want to write a SQL query that outputs some summary stats in a nicely formatted report.

Let’s for an example consider a first SQL query that takes the users over 57 year of age from the first table

SELECT count(*) AS OlderThank57
FROM table1
WHERE age >57

And from the second table we want to get the number of users that are female

SELECT count(*) AS FemaleUsers
FROM table2
WHERE gender = "female"

Now I want to have an output like the following

Number of Felame users from table 2: 514
Number of users over the age of 57 from table 1: 918

What is the best way of generating such a report?

Answer 1

I would offer to expand one level from Adrian’s answer… return as two separate fields so you could place them separately in a report, or align / format the number, etc

SELECT 'Number of Female users from table 2:' as Msg, 
       count(*) as Entries
  FROM table1
  WHERE age >57
UNION ALL
SELECT 'Number of users over the age of 57 from table 1:' as Msg, 
       count(*) as Entries
  FROM table2
  WHERE gender = "female"

You might have to force both “Msg” columns to the same padded length, otherwise one might get truncated. Again, just another option…
