[英]How to pass a variable to sqlplus in a bash script
I have a script like below. 我有一个如下的脚本。 My goal is write to a log file terminating with the current date and time as filename and spool to the file:
我的目标是写入一个以当前日期和时间作为文件名结尾的日志文件,并假脱机到该文件:
#!/bin/bash
year=`date +%Y`
month=`date +%m`
day=`date +%d`
prefixe=$month$day$year
logfile="/home/oracle/logs/exec_proc_daily_20_"$prefixe.log
sqlplus / "as sysdba" <<EOF
spool on
spool $logfile
execute Proc_RFC_MAJ_MV_ITIN;
execute Proc_RFC_MAJ_MV_REFGEO;
commit;
quit
EOF
When I execute the script, the spool $logfile
gives an error. 当我执行脚本时,
spool $logfile
给出错误。 No log is created. 没有日志创建。 But it works when I use something like
spool exec_proc_daily_2o.log
. 但是当我使用
spool exec_proc_daily_2o.log
类的东西时,它可以工作。 Why is the variable $logfile
not replace. 为什么变量
$logfile
不被替换。
After doing alot of digging, I found the solution to the problem. 经过大量挖掘之后,我找到了解决问题的方法。 On the line
sqlplus / "as sysdba" <<EOF
, I passed the variable like this sqlplus / as sysdba <<EOF >$logfile
. 在
sqlplus / "as sysdba" <<EOF
,我传递了像sqlplus / as sysdba <<EOF >$logfile
这样的变量。 So the complete code should be: 因此完整的代码应为:
#!/bin/bash
year=`date +%Y`
month=`date +%m`
day=`date +%d`
prefixe=$month$day$year
logfile="/home/oracle/logs/exec_proc_daily_20_"$prefixe.log
sqlplus / "as sysdba" <<EOF >$logfile
spool on
spool $logfile
execute Proc_RFC_MAJ_MV_ITIN;
execute Proc_RFC_MAJ_MV_REFGEO;
commit;
quit
EOF
[Edited with working example] Pass a variable to sqlplus: [使用工作示例进行编辑]将变量传递给sqlplus:
demo.sh 演示
export myvar1="hello"
export myvar2=123
sqlplus "/ as sysdba" @demo.sql $myvar1 $myvar2
echo "---shell is complete---"
demo.sql 演示程序
select 'first variable is &1 and second is &2'
from dual;
exit
@Beege answer works in Linux env. @Beege答案在Linux环境中有效。 I have made few changes as I don't I like to refer to &1 and &2 in SQL script everywhere.
我所做的更改很少,因为我不想在所有地方都在SQL脚本中引用&1和&2。
myvar1="hello"
myvar2=123
sqlplus username/password@SID @oracle_variabling_passing.sql $myvar1 $myvar2
echo "---shell is complete---"
oracle_variabling_passing.sql: oracle_variabling_passing.sql:
define first_var=&1
define second_var=&2
select 'first variable is &&first_var and second is &&second_var'
from dual;
exit
