mysql - MySql 中的分隔符错误

Question

我正在使用以下 sql:

DELIMITER $$

DROP PROCEDURE IF EXISTS `get_auto_increment_settings`$$

CREATE PROCEDURE `get_auto_increment_settings`()
BEGIN   
    select @@global.auto_increment_offset as 'offset', @@global.auto_increment_increment as 'increment' ;

END $$
DELIMITER ;

我将它存储在 db_auto_increment_settings_procedure.sql 中，当我尝试从 ant 执行它时，我遇到了以下错误:

[sql] Executing resource: /mysql/install/db_auto_increment_settings_procedure.sql
[sql] Failed to execute:  DELIMITER
[sql] com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: 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 'DELIMITER' at line 1
[sql] Failed to execute:  DELIMITER ;
[sql] com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: 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 'DELIMITER' at line 1

Answer 1

分隔符仅供 mysql 客户端使用(不用于 API、驱动程序...等)。
所以，它不会起作用。

查看您的错误消息:-

[sql] Executing resource: /mysql/install/db_auto_increment_settings_procedure.sql  
[sql] Failed to execute:  DELIMITER

很确定这将在 linux 系统中工作

mysql -u root -pxxx -h yyy < YOUR_SQL.sql

如果适用，您只需使用 mysql 客户端手动创建存储过程，
并且是一个简单的解决方案。

如果需要动态创建，
