mysql使用命令行执行存储过程

编写存储过程sql

以给brand表添加phone字段为例:

DROP PROCEDURE  IF EXISTS UpdateColum;
CREATE PROCEDURE UpdateColum()
BEGIN

SELECT database() INTO @dbName;
	
	
SET @tablename = 'brand';
SET @column_name = 'phone';
SELECT 
	CONCAT(
		'select count(*) into @colName from information_schema.columns where table_name = ''',
		@tablename,
		''' and column_name = ''',
		@column_name,
		''' and table_schema=''', 
		@dbName,
		''';'
		) 
INTO 
	@ckstring;

PREPARE SQLStr1 FROM @ckstring;
EXECUTE SQLStr1;
DEALLOCATE PREPARE SQLStr1; 
 
IF @colName = 0 THEN 
    ALTER TABLE 
		brand 
	ADD 
		phone varchar(255) NOT NULL DEFAULT '';
END IF;

END;


CALL UpdateColum();
DROP PROCEDURE  IF EXISTS UpdateColum;

命令行方式执行存储过程

执行以下命令:

    命令1: 选择操作的数据库
 user  dbname ;
命令2:修改行分割符

delimiter ;;

命令3:执行sql文件

source /root/xxx.sql

命令4:恢复行分割符

delimiter ;
