I need to create an SQL query to insert some data into a table

  • 0

I need to create an SQL query to insert some data into a table based on the results of a SELECT query into a local variable. My DB platform is MySQL 5.1, but I don’t think that should make a difference here. Basically, what I want to do is:

SELECT id INTO var_name FROM table1 WHERE some_column='something' LIMIT 1; INSERT INTO table2 (`number`) VALUES (@var_name);

I can’t get past the first statement, though, as I get the error ‘Undeclared variable var_name’. I’ve also tried putting the statement in a BEGIN/END block, and a stored procedure, but then I encounter other errors which state only that there is an error on the SELECT line. What am I doing wrong?
