Bash shell脚本中出现意外错误：“意外关键字`from`”。找不到错误

我已经编写了一个shell脚本，它将连接数据库并检索记录。但是当我超过它时，它给我的错误是：Unexpected关键字from。有人能告诉我我犯了什么错误吗？ 我所做的代码如下所示：

if test ${#incno} -lt 6 
then
    echo "Please provide 6 digit incident no";
    echo "TAC script has not been run";
    exit;
fi; 

cd ${SCRIPTINPUT}
if test -e *.csv 
then
    #cd ${SCRIPTINPUT}      
    for f in *.csv
    do
        dos2unix $f $f # To remove control M characters in the input file
        echo " $f - Control M characters removed sucessfully " >> input.log
    done
    echo " Control M characters present in all files in input folder has been removed " >>input.log


    cd ${SCRIPTINPUT}
    for INP in *.csv
    do  
        log_file="${SCRIPTLOG}/${INP}.log"
        # To check if input file for Taccode or Not
        cd ${SCRIPTINPUT}

            echo "Taccode to be executed for the file $INP"
            count=0;
            while read line
            do
                pcode=`echo $line | cut -d "," -f "1"`
                tcode=`echo $line | cut -d "," -f "2"`

                cpcode=${#pcode}

                if test $cpcode -eq 5 
                then
                    DBRESULT=`sqlplus sprint2/sh3rl0ck@SPRXP03 

                    select * from mytable where productcode='10130' AND taccode='35710100';
                    quit;`

                    echo "Hello $count:$pcode:$tcode:$DBRESULT"

                    #here the database result should be checked for errors

                    if test $? -ne 0
                    then
                        echo "Query execution failed.Check ${log_file} file for errors!"
                        mv ${SCRIPTINPUT}/$INP ${SCRIPTNOTPROCESSED}

                    else
                        count=$(expr $count + 1)
                        echo "Record No:${count} ${pcode}:${tcode}" >>${log_file}
                    fi;
                else
                    echo "Problem with product code or tac code. Check log file for errors"

我认为您需要将sqlplus命令全部放在一行上

DBRESULT=`sqlplus sprint2/sh3rl0ck@SPRXP03 select * from mytable where productcode='10130' AND taccode='35710100'; quit;`

或包含显式换行符

DBRESULT=`sqlplus sprint2/sh3rl0ck@SPRXP03 \
    select * from mytable where productcode='10130' AND taccode='35710100'; \
    quit;`

Oracle sqlplus不支持内联sql语句。它唯一的命令行支持是使用@运行sql脚本。解决问题的可行方法是使用heredoc

您可以执行以下操作：

DBRESULT=$(sqlplus sprint2/sh3rl0ck@SPRXP03 <<-SQL
    select * from mytable where productcode='10130' AND taccode='35710100';
    exit;
SQL

将脚本粘贴到将有助于指出错误的来源，尽管实际的错误消息并不完全是真实的。我删掉了看起来明显的复制/粘贴错误。请检查编辑以确保我没有删除任何重要内容。我还希望警告您明确检查$？，或多次将cd放入同一目录。不过，这些主要是风格上的问题。此外，您需要用反斜杠转义*或者更好地正确引用SQL。另外，强烈建议使用$command而不是'command'，这是一个很好的理由。建议不错。代码正在运行。您能告诉我是否有任何方法建立持久性数据库连接吗。激发多个查询，然后关闭一个连接？有一种方法可以使用两个管道。这比你想象的要简单得多。
