Question

When I run the code below inside phpmyadmin I get an error “Undefined Variable tmpportfolio”

what is the problem?

SQL:

CREATE TEMPORARY TABLE tmpportfolio (p_name VARCHAR(255),portfolio_id INT UNSIGNED NOT NULL);

SELECT p_name, portfolio_id INTO tmpportfolio
    FROM portfolio
    WHERE parent_portfolio_id IS NULL
    AND portfolio_id NOT IN
        (
           SELECT x.parent_portfolio_id
           FROM portfolio x
           WHERE x.parent_portfolio_id IS NOT NULL
        )
    AND account_id = 1

SELECT * FROM tmpportfolio;

Answer 1

Just join first two SQL statement in one CREATE TABLE … SELECT statment:

CREATE TABLE tmpportfolio SELECT p_name, portfolio_id FROM portfolio
    WHERE parent_portfolio_id IS NULL
    AND portfolio_id NOT IN
        (
           SELECT x.parent_portfolio_id
           FROM portfolio x
           WHERE x.parent_portfolio_id IS NOT NULL
        )
    AND account_id = 1

SELECT * FROM tmpportfolio;
