我想在使用之前将 ksh shell 变量作为整数传递给 sqlplus 或将变量转换为数字。这是我编写的代码(不起作用):
echo
echo "Enter the day of run (1,2,3,..,N ) :" | tee -a $sqllog
read day
typeset -i first_range
if [ $day -eq 1 ]; then
first_range=5000
elif [[ $day -eq 2 ]]; then
first_range=105000
elif [[ $day -eq 3 ]]; then
first_range=205000
elif [[ $day -eq 4 ]]; then
first_range=305000
elif [[ $day -eq 5 ]]; then
first_range=405000
elif [[ $day -eq 6 ]]; then
first_range=505000
elif [[ $day -eq 7 ]]; then
first_range=605000
fi
echo "first_range value : ${first_range}" | tee -a $sqllog
{
sqlplus -S ${SF_PSTN_CONN_STRING} << EOF
alter session enable parallel DML;
--alter session set db_file_multiblock_read_count=128;
alter session enable parallel query;
set heading off
set verify off
set echo off
set pages 0
set timi on
set lines 300
set trimspool on
# Drop table TMP_DAILY_PSTN_CMP_11035
drop table TMP_DAILY_PSTN_CMP_11035;
# Create TMP Table TMP_DAILY_PSTN_CMP_11035 from TMP_OA_PSTN_CMP_11035
Create table TMP_DAILY_PSTN_CMP_11035 (
ACTION_OBJID NUMBER,
CONTRACT_OBJID NUMBER,
STATUS varchar2(40),
UPDATE_DATE DATE
)
partition by range(ACTION_OBJID)(
partition p1 values less than (${first_range})) NOLOGGING parallel;
prompt the day of run is $day;
begin
for k in 2..200
loop
execute immediate
'alter table TMP_DAILY_PSTN_CMP_11035 add partition p'||k||' values less than ('||${first_range}+(k*5000)||')';
end loop;
end;
/
我得到的错误是:
Enter the day of run (1,2,3,..,N ) :
2
first_range value : 105000
Session altered.
Session altered.
Table dropped.
Elapsed: 00:00:00.03
Table created.

the day of run is 2
begin

我该如何解决这个问题,即将字符转换为数字,甚至typeset -i
似乎不起作用。将变量传递给 sqlplus 很容易,很多问题都涉及到它,但我特别想传递一个整数值并使用它
编辑:我正在使用 oracle 10g db。
