我有shell脚本调用以下sql脚本：
INSERT INTO SEMANTIC.COUNT_STATISTICS (...);
UPDATE SEMANTIC.COUNT_STATISTICS
SET PRNCT_CHANGE = 1.1;
--want to store result of this bellow select statement in model_count variable
select PRNCT_CHANGE
FROM SEMANTIC.COUNT_STATISTICS
WHERE model = '&MY_MODEL'
AND NEW_DATE = (
select max(NEW_DATE)
from SEMANTIC.COUNT_STATISTICS
where MODEL = '&MY_MODEL'
);
现在,如何将此PERCENTAGE_NUMBER变量返回到我的shell脚本？
我的shell脚本如下：
#!/bin/bash # # setup oracle,java,and d2rq environment . /etc/profile.d/oracle.sh . /etc/profile.d/java.sh . /etc/profile.d/d2rq.sh cd /opt/D2RQ model_count=$(sqlplus user/pass @count.sql 'MODEL') if ["$model_count" > 0]; then echo "percentage count is positive" else echo "its negative"
我想将最后一个SELECT语句结果存储到shell脚本中的model_count变量中.
谁知道为什么不工作？
使用bash函数的bash示例(注意！数据库操作系统身份验证“/”)
原文链接：https://www.f2er.com/oracle/205664.html#!/bin/bash
get_count () {
sqlplus -s / <<!
set heading off
set Feedback off
set pages 0
select count(*) from all_objects where object_type = '$1';
!
}
count=$(get_count $1)
echo $count
if [ "$count" -gt 0 ]; then
echo "is greater than zero"
else
echo "is less or equal to zero"
fi
~/tmp/ $./count.sh INDEX
2922
is greater than zero
~/tmp/ $./count.sh TABLE
1911
is greater than zero
~/tmp/ $./count.sh FUNCTION
226
is greater than zero
~/tmp/ $./count.sh "SUPEROBJECT"
0
is less or equal to zero
