如何在 sql 脚本中传递 20100201 的参数?我每次都需要更改此日期格式.

How can I pass a parameter for 20100201 in side the sql script? I need to change every time this date format.

如何调用这个 sql 脚本并通过将日期作为参数在 unix 中运行它?所以每次运行时都应该修改脚本中的日期.

How can I call this sql script and run it in unix by passing date as parameter? So that date in the script should be modified in every run.

推荐答案

SQL*Plus 使用 &1, &2... &n 来访问参数.

SQL*Plus uses &1, &2... &n to access the parameters.

假设您有以下脚本 test.sql:

SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off

你可以这样调用这个脚本，例如:

you could call this script like this for example:

$ sqlplus login/pw @test Hello World!

在 UNIX 脚本中，您通常会像这样调用 SQL 脚本:

In a UNIX script you would usually call a SQL script like this:

sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF

这样其他会话的ps
