我在目录 / tmp / SQL_QUERY 中有一个脚本说 sql_result.sh ，它只是在同一个位置调用sql脚本并执行sql命令。 代码：
sqlplus -S $MY_UN/$MY_PW@$MY_DB <<!
set serveroutput on;
@/tmp/SQL_QUERY/sql_file1
quit
!
但是，如果我在该目录中说了2个SQL文件 sql_file1.sql 和 sql_file1.sql_new 。我的unix脚本会选择哪个sql脚本？怎么样和为什么？

答案 0 :(得分：0)
简答：通常sql_file1.sql
默认扩展名为.SQL，如@ file_name[.ext]
Represents the script you wish to run. If you omit ext, SQL*Plus assumes the default
command-file extension (normally SQL). For information on changing the default extension,
see the SUFFIX variable of the SET command.
中所述：
SET正如它所说，您可以使用Sets the default file extension that SQL*Plus uses in commands that refer to scripts. SUFFIX does not control extensions for spool files.
Example
To change the default command-file extension from the default, .SQL to .UFI, enter
SET SUFFIX UFI
If you then enter
@EXAMPLE
SQL*Plus will look for a file named EXAMPLE.UFI instead of EXAMPLE.SQL.
命令更改使用的扩展名，或者您可以在脚本中明确指定扩展名。
