使sql匹配bash ksh（AIX）oracle数据库中的数据

Question

我想通过外壳检查sqlplus命令的两个输出是否匹配。因此，我循环执行，直到捕获到该输出的变量相等为止，然后结束循环，然后执行下一组指令。

以下提到的循环均未按预期运行。

我希望实时获取testSeq和expectedSeq的数据，然后进行比较以检查数据，如果它们相等，请退出并进行下一步。

testSeq=`sqlplus -S user/xxxxxxxxx@${primary} << EOF
set heading off feedback off pagesize 0 verify off echo off numwidth 15 
select max(ARCHIVED_SEQ#) from v\\$ARCHIVE_DEST_STATUS;
EOF`

expectedSeq=`sqlplus -S user/xxxxxxxxx@${DR}<< EOF
set heading off feedback off pagesize 0 verify off echo off numwidth 15 
select max(APPLIED_SEQ#) from V\\$ARCHIVE_DEST_STATUS;
EOF`
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

while (true)
    do
    while do;

    testSeq=`sqlplus -S user/xxxxxxxxx@${primary} << EOF
    set heading off feedback off pagesize 0 verify off echo off numwidth 15 
    select max(ARCHIVED_SEQ#) from v\\$ARCHIVE_DEST_STATUS;
    EOF`

    expectedSeq=`sqlplus -S user/xxxxxxxxx@${DR}<< EOF
    set heading off feedback off pagesize 0 verify off echo off numwidth 15 
    select max(APPLIED_SEQ#) from V\\$ARCHIVE_DEST_STATUS;
    EOF`

       if [[ "$testSeq" != "$expectedSeq" ]] 
       then
       echo "$DR sync is in Progress." | mailx -s "$DR Refresh update" [email protected]
       else
       sleep 20
    echo "$DR is in sync with ${PRIMARY} and ready to be switched to Snapshot DR" | mailx -s "$DR Refresh update" [email protected]
    done

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

    while [[ "$testSeq" != "$expectedSeq" ]]; do
    echo "$DR sync is in Progress." | mailx -s "$DR Refresh update" [email protected]

    sleep 20

    done
    echo "$DR is in sync with ${PRIMARY} and ready to be switched to Snapshot DR" | mailx -s "$DR Refresh update" [email protected]


+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

until [ "$expectedSeq" -eq "$testSeq" ]; do
echo "$DR sync is in Progress." | mailx -s "$DR Refresh update" [email protected]
sleep 5 
if [ $? -eq 0 ]; then
break
fi
done
echo "$DR is in sync with ${PRIMARY} and ready to be switched to Snapshot DR" | mailx -s "$DR Refresh update" [email protected]

感谢所有帮助。在此先感谢

这应该与bash一起使用，我没有测试ksh：

expectedSeq=`sqlplus -S user/xxxxxxxxx@${DR} <<EOF
set heading off feedback off pagesize 0 verify off echo off numwidth 15 
select max(APPLIED_SEQ#) from V\\$ARCHIVE_DEST_STATUS;
EOF`
testSeq=

while [[ $testSeq != $expectedSeq ]]; do
    if [[ -n testSeq ]]; then
        echo "$DR sync is in Progress."
        sleep 20
    fi
    testSeq=`sqlplus -S user/xxxxxxxxx@${primary} <<EOF
set heading off feedback off pagesize 0 verify off echo off numwidth 15 
select max(ARCHIVED_SEQ#) from V\\$ARCHIVE_DEST_STATUS;
EOF`
    # todo: handle failures
done
echo "$DR is in sync with ${primary} and ready to be switched to Snapshot DR"

可以在循环外定义期望的输出，只要该表在此过程中没有变化。您应该为grepping输出中的错误做好准备，以防查询失败。
