以下是一个示例代码，可用于编写SQL存储过程，实现传入两个值列表，从表中查找其组合并返回数组。

创建示例表：

CREATE TABLE combinations ( id INT NOT NULL, value1 VARCHAR(50) NOT NULL, value2 VARCHAR(50) NOT NULL, result VARCHAR(50) NOT NULL, PRIMARY KEY (id) );

插入示例数据：

INSERT INTO combinations (id, value1, value2, result) VALUES (1, 'A', '1', "Result 1"), (2, 'A', '2', "Result 2"), (3, 'B', '1', "Result 3"), (4, 'B', '2', "Result 4");

编写存储过程：

CREATE PROCEDURE get_combination_results (IN value1_list VARCHAR(255), IN value2_list VARCHAR(255), OUT result_list TEXT) BEGIN DECLARE separator CHAR(1) DEFAULT ','; DECLARE value1 VARCHAR(50); DECLARE value2 VARCHAR(50); DECLARE result TEXT DEFAULT '';

-- 在值列表中查找所有值的组合 WHILE LOCATE(separator, value1_list) > 0 AND LOCATE(separator, value2_list) > 0 DO SET value1 = SUBSTRING(value1_list, 1, LOCATE(separator, value1_list) - 1); SET value1_list = SUBSTRING(value1_list, LOCATE(separator, value1_list) + 1); WHILE LOCATE(separator, value2_list) > 0 DO SET value2 = SUBSTRING(value2_list, 1, LOCATE(separator, value2_list) - 1); SET value2_list = SUBSTRING(value2_list, LOCATE(separator, value2_list) + 1); -- 查询组合并将结果拼接到结果列表中 SELECT result INTO result_list FROM combinations WHERE value1 = value1 AND value2 = value2; SET result_list = CONCAT(result_list, ',', result); END WHILE; END WHILE;

--
