如何通过 sql plus 从命令行发出单个命令?
使用 SQL Plus，您可以从命令行运行带有@"运算符的脚本，如下所示:
Using SQL Plus, you can run a script with the "@" operator from the command line, as in:
c:>sqlplus username/password@databasename @"c:my_script.sql"
但是是否可以只运行具有类似语法的单个命令，而不需要一个完整的单独脚本文件?如:
But is it possible to just run a single command with a similar syntax, without a whole separate script file? As in:
c:>sqlplus username/password@databasename @execute some_procedure
我对这个很感兴趣，因为我想写一个批处理文件，只执行一个命令，而不生成一堆两行.sql"文件.
I am interested in this because I want to write a batch file that simply executes a command, without generating a bunch of two-line ".sql" files.
推荐答案
我能够通过将 SQL 查询通过管道传输到 SQL*Plus 来运行它:
I'm able to run an SQL query by piping it to SQL*Plus:
@echo select count(*) from table; | sqlplus username/password@database
给予
@echo execute some_procedure | sqlplus username/password@databasename
试一试.
