Table name – firms

SELECT Firm, SUM(IF(sex='man',1,0)) AS Man, SUM(IF(sex='woman',1,0)) AS Woman FROM firms GROUP BY Firm;

The following table shows the required storage and range for each of the integer types.

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants.

With one argument:

SELECT * FROM tbl LIMIT 10;     # Retrieve first 10 rows

With one argument, the value specifies the number of rows to return from the beginning of the result set.

With two arguments:

SELECT * FROM tbl LIMIT 2,20;  # Retrieve rows from 3 to 22

With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1).
