Question

I got a table of ids from 1 to 1000. How can I select to rows from my table and insert the result in to two variables that I declare?

Some thing like this:

Select from table1 where id = 1 or id = 27 into var1, var2

Answer 1

You can do that, but you need to confirm to the following two limitations:

1. The result set must contain exactly one row
2. The row must contain exactly two columns

See this:

SELECT 'foo', 4 FROM DUAL INTO @a, @b;

SELECT @a, @b;
+------+------+
| @a   | @b   |
+------+------+
| foo  |    4 |
+------+------+

And also possible:

SELECT MIN(id), MAX(Population) FROM world.City INTO @min_id, @max_pop;

SELECT name, population FROM world.Country LIMIT 1 INTO @name, @pop;
