SQL代码不工作，未知错误

Question

我已经写了一段代码：

CREATE PROCEDURE test() 
BEGIN 
    DECLARE 
    ok INT default FALSE; 
    curs_r1 CURSOR FOR SELECT * FROM t WHERE (b > 1 and b < 3) and (c < 2); 
    curs_r2 CURSOR FOR SELECT * FROM t WHERE (a = 1) and (b > 2); 
    CONTINUE HANDLER FOR NOT FOUND SET ok = TRUE; 


    SET ok = False; 
    DROP TABLE IF EXISTS t; 
    CREATE TABLE IF NOT EXISTS t (
    id int, 
    a int, 
    b int, 
    c int 
); 
    DROP TABLE IF EXISTS res; 
    CREATE TABLE IF NOT EXISTS res (
    id int not null unique, 
    score float 
); 

    insert into t values (0,1,2,3), (1,1,3,2), (2,3,2,1); 

    -------------------------------------------- 
    OPEN curs_r1; 
    SET score_r1 = 0.5; 
    REPEAT 
    FETCH curs_r1 INTO 
    id, a, b, c; 
    INSERT IGNORE INTO res VALUES (id, score_r1); 
    UNTIL ok END REPEAT; 
    CLOSE curs_r1; 

    -------------------------------------------- 
    SET ok = FALSE; 

    OPEN curs_r2; 
    SET score_r2 = 0.25; 
    REPEAT 
    FETCH curs_r2 INTO 
    id, a, b, c; 
    INSERT IGNORE INTO res VALUES (id, score_r2); 
    UNTIL ok END REPEAT; 
    CLOSE curs_r2; 



    SELECT * FROM res; 
END 

但这产生类似的错误太多：

Error: near line 1: near "PROCEDURE": syntax Error

Error: near line 5: near "curs_r1": syntax Error

Error: near line 6: near "curs_r2": syntax Error

Error: near line 7: near "CONTINUE": syntax Error

Error: near line 45: near "UNTIL": syntax Error

没有人有根源的想法请？

非常感谢你提前。

以上，其中固定的错误（感谢你达尔文的第一个线索），这里是新的一段代码：

DELIMITER $$ 
DROP PROCEDURE IF EXISTS test; 
CREATE PROCEDURE test() 
BEGIN 
    DECLARE ok INT default FALSE; 
    DECLARE score_r1 FLOAT default 0.5; 
    DECLARE score_r2 FLOAT default 0.25; 
    DECLARE id, a, b, c INT; 
    DECLARE curs_r1 CURSOR FOR SELECT * FROM t WHERE (b > 1 and b < 3) and (c < 2); 
    DECLARE curs_r2 CURSOR FOR SELECT * FROM t WHERE (a = 1) and (b > 2); 
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET ok = TRUE; 

    SET ok = False; 
    DROP TABLE IF EXISTS t; 
    CREATE TABLE IF NOT EXISTS t (
    id int, 
    a int, 
    b int, 
    c int 
); 
    DROP TABLE IF EXISTS res; 
    CREATE TABLE IF NOT EXISTS res (
    id int not null unique, 
    score float 
); 

    insert into t values (0,1,2,3), (1,1,3,2), (2,3,2,1); 

    OPEN curs_r1; 
    OPEN curs_r2; 

    REPEAT 
    FETCH curs_r1 INTO id, a, b, c; 
    INSERT IGNORE INTO res VALUES (id, score_r1); 
    UNTIL ok END REPEAT; 
    CLOSE curs_r1; 

    SET ok = FALSE; 


    REPEAT 
    FETCH curs_r2 INTO id, a, b, c; 
    INSERT IGNORE INTO res VALUES (id, score_r2); 
    UNTIL ok END REPEAT; 
    CLOSE curs_r2; 

    SELECT * FROM res; 
END; 
$$ 
DELIMITER ; 

输出

，我期待看到两行编号= 2和id = 1 但我只有一行ID = 0和得分= 0.5

我在这里错过了什么？ 非常感谢你

Answer 1

所以，基本上你会得到每条语句的错误信息。为了建立从mysql客户端程序，您必须DELIMITER指令内包围整个CREATE声明，就像这样：

DELIMITER $$ 
CREATE PROCEDURE test() 
    BEGIN 
    ... --code body goes here 
    END; 
$$ 
DELIMITER ; 

你做你的代码有许多其他错误，但这样做解决了第一个。
