Question

我有以下bash脚本，应该用当前日期调用sqlplus。

#!/bin/bash

DATE='date +%F'

sqlplus -s << EOF1
DB_username/DB_password
set heading off
exec PLSQL_PROCEDURE('$DATE', '-30','someString','/home/outputFolder');
exit
EOF1

exit

但我得到以下错误 - 它肯定不会评估date命令：

BEGIN PLSQL_PROCEDURE('date +%F', '-30', 'someString', '/home/outputFolder'); END;

ERROR at line 1:
ORA-01841: (full) year must be between -4713 and +9999, and not be 0
ORA-06512: at "DataBaseName.PLSQL_PROCEDURE", line 19
ORA-06512: at line 1

如何修复它以便它传递当前日期，就像这样？

PLSQL_PROCEDURE('2013-03-14', '-30', 'someString', '/home/outputFolder');

请改为尝试：

#!/bin/sh

DATE=$(date +%F) # note the $( ) form

sqlplus -s  << EOF1
DB_username/DB_password
set heading off
exec PLSQL_PROCEDURE('$DATE', '-30','someString','/home/outputFolder');
exit
EOF1

您应该了解命令替换：$(foo bar)导致命令'foo'以参数'bar'执行，$(..)将被<{1}}替换EM>输出。见http://mywiki.wooledge.org/BashFAQ/002

将日期从bash脚本中传递到sqlplus命令
