oracle – 从sql脚本返回值到shell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？

#!/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
