Question

I have to make

SELECT column1,column2
INTO OUTFILE 'out_1.csv'
FROM table1
WHERE column1.name = '1'

SELECT column1,column2
INTO OUTFILE 'out_2.csv'
FROM table1
WHERE column1.name = '2'

SELECT column1,column2
INTO OUTFILE 'out_3.csv'
FROM table1
WHERE column1.name = '3'

and so on…
I thought it was a good idea to do something like:

SELECT column1,column2
INTO OUTFILE 'out_$1.csv'
FROM table1
WHERE column1.name = $1

and pass the parrameter $1 through a UNIX shell script. But maybe there’s a better way.
There is a SQL “native” way to iterate through a range from 1 to 40?

Answer 1

Sure. You can create a stored procedure and use LOOP or WHILE.
