Re: Retrieving a numeric series from a SELECT
Hi, Fellows! Sorry for my poor english. Thats why I can explain myself properly. :- ) What I really want is a calculate column with consecutive numbers from n to m, where n can be any number, and m depending on the result of the WHERE clause. I need to print pay orders for students, this pay orders use a consecutive control number, the criteria to select students use to be variable. Example: SELECT colnum, id, name FROM students WHERE status='OK' (4 rows selected) or SELECT colnum, id, name FROM students WHERE grade=1 (230 rows selected) colnum must be the same number that is printed in the pay order. The next pay order on the printer is 15000, then colnum of the first row of the SELECT must be 15100, the next row 15001, and so on. you get it? I remember that the sample i saw in this SQL list only used a SELECT statement without a table, or whitout a memory variable. it was only a SELECT something, and it returns a consecutive serie from 1 to 100.

Re: Retrieving a numeric series from a SELECT
Hi, If you have a table with at least the number of rows that you want in your series you can do this. Set @Colnum := 0; Select @Colnum := @colnum+1 as colnum from tablename limit (number of rows required); set @column := 0; If you want a series starting from a value other than 1, initialize colnum value to one less than required starting value.

Do you mean you want to specify a beginning and ending number and generate a series containing all the numbers from the beginning to the end? Or something else?
