SQL 服務器存儲過程，遍歷表並獲取值？

Question

在下面顯示的代碼中，我遍歷一個表（在本例中為學科表）並想將記錄添加到另一個表中，我對此很陌生

如何從這些表中檢索插入命令的值？

CREATE PROCEDURE cdisc 
    -- check disciplines
AS
BEGIN
    DECLARE test CURSOR FAST_FORWARD FOR
        SELECT * 
        FROM tbl_portfolio 
        WHERE show = 'Ja' ;

    WHILE @@FETCH_STATUS = 0
    BEGIN
        DECLARE disc CURSOR FAST_FORWARD FOR 
            SELECT * 
            FROM disciplines;

        WHILE @@fetch_status = 0
        BEGIN
            INSERT INTO ProjectDisciplines (Proj_id, discipline_ID) 
            VALUES (disc!ID, test!id)
        END 

        CLOSE disc
        DEALLOCATE disc
    END

    CLOSE test
    DEALLOCATE test
END
