[英]Use a database value in SQLPLUS as a parameter to a batch file
I need to run a batch file and pass in a database value. 我需要运行批处理文件并传入数据库值。 Depending on the day, a different value needs to be passed into the DOS command. 根据日期,需要将不同的值传递到DOS命令。 This particular business rule is defined in a view in the database. 此特定业务规则在数据库的视图中定义。
Our primary scheduling tool is datastage which runs scripts in SQLPLUS, so this is my preferred method for schedules activities. 我们的主要调度工具是在SQLPLUS中运行脚本的数据存储,因此这是我首选的调度活动方法。 I could also run a batch file directly taht calls SQLPLUS and gets a value, but there is much more hassle setting it up so I'd prefer not to. 我也可以直接运行一个批处理文件,直接调用SQLPLUS并获取一个值,但是设置它会有更多的麻烦,所以我不想这样做。
I'm a SQLPLUS amateur. 我是一个SQLPLUS业余爱好者。
The SQL script I'm passing into SQLPLUS is below. 我传入SQLPLUS的SQL脚本如下。 The problem I'm having is it's passing in :sTriggerName, not the value of it. 我遇到的问题是传入:sTriggerName,而不是它的值。
set echo on
set feedback on
set termout on
VAR sTriggerName VARCHAR2(100)
SELECT TRIGGERNAME INTO :sTriggerName
FROM SCHEMA.VIEW
WHERE CALENDAR_DATE = TRUNC(SYSDATE) AND ROWNUM < 2;
/
HOST "E:\CallScheduleTrigger.CMD :sTriggerName."
quit
In the example above I am using a bind variable. 在上面的例子中,我使用的是绑定变量。

To load aa database value into a substitution variable called sTriggerName
将数据库值加载到名为sTriggerName
的替换变量中
COLUMN TRIGGERNAME new_value sTriggerName
SELECT TRIGGERNAME FROM SCHEMA.VIEW WHERE CALENDAR_DATE = TRUNC(SYSDATE) AND ROWNUM < 2;
To use this substitution variable in a host command (ie as a parameter to a batch file): 要在主机命令中使用此替换变量(即作为批处理文件的参数):
HOST "E:\CallScheduleTrigger.CMD &sTriggerName"
