Question

我查看了类似的问题，但似乎没有一个能帮助我解决我得到的错误。

以下是我要创建的程序：

CREATE PROCEDURE replaceFieldTextTo (IN v_string_from VARCHAR(255), IN v_string_to VARCHAR(255))
BEGIN
  DECLARE done INT DEFAULT FALSE;
  DECLARE table_name_value VARCHAR(64);
  DECLARE column_name_value VARCHAR(64);
  DECLARE cursor_fields CURSOR FOR SELECT TABLE_NAME, COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME LIKE 'field_%_value';
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

  OPEN cursor_fields;

  ColumnList: LOOP
    FETCH cursor_fields INTO table_name_value, column_name_value;

    IF done THEN 
      Leave ColumnList;
    END IF;

    SET @sql = CONCAT('UPDATE ', table_name_value, ' SET ', column_name_value, ' = replace(', column_name_value, ', "', v_string_from, '", "', v_string_to ,'"');

    PREPARE stmt FROM @sql;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
  END LOOP;

  CLOSE cursor_fields;
END;

语句本身创建得很好。但是调用它会导致错误。

基本上我想在多个表中查找和替换文本，但我得到：

mysql> CALL replaceFieldTextTo("http://dev.mywebsite.org","/");
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

我没有真正看到这个问题。我在mysql控制台中使用delimiter //和delimiter ;之后将其作为前缀。

ERROR 1064（42000）第1行的MySQL存储过程错误？
