外壳脚本中的意外错误："Unexpected keyword `from` " 。无法找到错误

Question

我已经编写了一个shell脚本，该脚本将连接数据库并检索记录。但当我对它进行优化时，它会给我一个错误：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：

incno=$1;
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"`

                #ctcode=`echo ${tcode} | grep -oE [[:digit:]] | wc -l`
                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 ${SCRIPTNOTPROCESSED}
                        exit;   
                    else
                        count=$(expr $count + 1)
                        echo "Record No:${count} ${pcode}:${tcode}" >>${log_file}
                    fi;
                else
                    echo "Problem with product code or tac code. Check log file for errors"
                    echo "Record No:${count} ${pcode}:${tcode}:" >>${log_file}
                    mv ${SCRIPTINPUT}/$INP ${SCRIPTNOTPROCESSED}
                    exit;
                fi;
            done <${INP}   #end file reading while loop
            echo "Script excution succeeded" >>${log_file}
            echo "${count} records inserted"
            echo "Script excution succeeded";
    done #end outer for loop
else
    echo "No csv files found in input directory. -TAC script has not been run."
fi;

Answer 1

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;`

或包括显式换行

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

Answer 2

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。解决您问题的可行方法是使用heredoc。

你可以做一些类似的事情：

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