mysql中实现字符串分割sp_split

 

sp_split :

DELIMITER $$

CREATE DEFINER = 'test_user'@'%'
PROCEDURE sp_split (IN p_str varchar(2000), IN p_split varchar(50), p_table_insert varchar(50), p_col_insert varchar(50))
BEGIN
  IF p_str > '' THEN
    WHILE (INSTR(p_str, p_split) <> 0) DO
      SET @value = SUBSTRING(p_str, 1, INSTR(p_str, p_split) - 1);
      SET @sql = CONCAT('INSERT ', p_table_insert, '(', p_col_insert, ') VALUES (?)');
      PREPARE stmt FROM @sql;
      EXECUTE stmt USING @value;
      SET p_str = INSERT(p_str, 1, INSTR(p_str, p_split), '');
    END WHILE;
    SET @value = p_str;
    SET @sql = CONCAT('INSERT ', p_table_insert, '(', p_col_insert, ') VALUES (?)');
    PREPARE stmt FROM @sql;
    EXECUTE stmt USING @value;
    DEALLOCATE PREPARE stmt;
  END IF;
END
$$

DELIMITER ;

 

e.g.

 

 

CREATE TEMPORARY TABLE IF NOT EXISTS tmp_stock (stock_id int);
TRUNCATE TABLE tmp_ou;
  CALL sp_split(p_ouid_list,',','tmp_ou','ou_id');
