Sybase ASA中几个非常有用的存储过程

Sybase ASA中几个非常有用的存储过程

以下过程非常实用:    

1. Send UDP包到指定地址：

sa_send_udp

CALL sa_send_udp( '10.25.99.196', 2345', 'This is a test' );

2. 获取当前系统中活跃的事务列表：

call sa_transactions( )

3. 有用的tsql 环境设置

CREATE PROCEDURE dbo.sp_tsql_environment()

BEGIN

    IF db_property( 'IQStore' ) = 'Off' THEN

        -- SQL Anywhere datastore

        SET TEMPORARY OPTION close_on_endtrans='OFF';

    END IF;

    SET TEMPORARY OPTION ansinull='OFF';

    SET TEMPORARY OPTION tsql_variables='ON';

    SET TEMPORARY OPTION ansi_blanks='ON';

    SET TEMPORARY OPTION chained='OFF';

    SET TEMPORARY OPTION quoted_identifier='OFF';

    SET TEMPORARY OPTION allow_nulls_by_default='OFF';

    SET TEMPORARY OPTION on_tsql_error='CONTINUE';

    SET TEMPORARY OPTION isolation_level='1';

    SET TEMPORARY OPTION date_format='YYYY-MM-DD';

    SET TEMPORARY OPTION timestamp_format='YYYY-MM-DD HH:NN:SS.SSS';

    SET TEMPORARY OPTION time_format='HH:NN:SS.SSS';

    SET TEMPORARY OPTION date_order='MDY';

    SET TEMPORARY OPTION escape_character='OFF';

END

4. 执行操作系统命令

xp_cmdshell system procedure 

Carries out an operating system command from a procedure.

xp_cmdshell( 'dir > c: emp.txt', 'no_output' )

5. 读取写入文件

xp_read_file

xp_write_file

6. 获取某一个表的 DDL语句

sa_get_table_definition system procedure 

select row_value from sa_split_list( sa_get_table_definition('DBA', 'ttt'), char(10));

row_value

CREATE TABLE "DBA"."ttt" (

    "abc"                            timestamp NULL

)

;

7. 发送邮件

CALL xp_startsmtp( smtp_sender = 'xxx@163.com', smtp_server='smtp.163.com', smtp_port='25',

timeout=240, smtp_auth_username='iihero', smtp_auth_password='***');

CALL xp_sendmail( recipient='xxxx@gmail.com',

      subject='New Pricing');

call xp_stopmail();
