无法通过 shell 执行 .sql 来生成 csv 文件答案

【问题标题】：Unable to geneate csv file from by executing .sql through shell无法通过 shell 执行 .sql 来生成 csv 文件

【问题描述】：

我正在尝试通过调用 .sql 文件来生成 csv。问题在于执行时正在创建一个空文件。对数据库运行 sql 会返回记录。抱歉，如果这个问题已经得到解答，但我无法找到任何解决我问题的答案。

FILE="CASE.csv"
export dest_loc=/dest/loc
export LOGFILE=$LOG/100.$NOW_TS.log
echo "$0 started at $(date +"%Y-%m-%d:%H:%M:%S")" > ${LOGFILE}
sqlplus -s $DB_LOGIN<<EOSQL>>${LOGFILE}
SET echo OFF
SET feedback OFF    
SET sqlprompt ''    
SET TERMOUT OFF
SET UNDERLINE OFF
SET trimspool ON
SET trimout ON
SET SQLBLANKLINES ON
SET PAGESIZE 50000
SET COLSEP "|"
SET LINESIZE 650
SPOOL $dest_loc/$FILE
@$SRC/sql_to_run.sql
SPOOL OFF
EOSQL
echo "\nChecking for ORACLE errors..."                            >> ${LOGFILE}
grep 'ORA-' $LOGFILE                                              >> ${LOGFILE}
rc=$?
if [ ${rc} = 0 ];
then
   echo "\nThere has been an ORACLE error. RC = $RC"   >> ${LOGFILE}
   echo "\n$0 ended at $(date +"%Y-%m-%d:%H:%M:%S")"   >> ${LOGFILE}
   echo "####################################"  >> ${LOGFILE}
   exit 2
else 
   echo "\nNo ORACLE errors found."   >> ${LOGFILE}
fi

捕获的日志文件

./100.sh 开始于 2021-10-20:20:14:22 检查 ORACLE 错误... 未发现 ORACLE 错误。

【解决方案1】：

csv 文件为空的原因可能是因为您有一个未捕获的错误。 sqlplus 是一个二进制程序，因此它将始终以 0 退出，除非您使用 whenever sqlerror 和 whenever oserror 来捕获执行中产生的异常，无论是由于数据库错误还是操作系统问题。

12c 之前

FILE="CASE.csv"
export dest_loc=/dest/loc
export LOGFILE=$LOG/100.$NOW_TS.log
echo "$0 started at $(date +"%Y-%m-%d:%H:%M:%S")" > ${LOGFILE}
sqlplus -s $DB_LOGIN << EOSQL >> ${LOGFILE}
WHENEVER SQLERROR EXIT FAILURE;
WHENEVER OSERROR EXIT FAILURE;
SET echo OFF
SET feedback OFF    
SET sqlprompt ''    
SET TERMOUT OFF
SET UNDERLINE OFF
SET trimspool ON
SET trimout ON
SET SQLBLANKLINES ON
SET PAGESIZE 50000
SET COLSEP "|"
SET LINESIZE 650
SPOOL $dest_loc/$FILE
@$SRC/sql_to_run.sql
SPOOL OFF
EOSQL
rc=$?
if [ ${rc} -ne 0 ];
then
   echo "\nThere has been an ORACLE error. RC = $RC"   >> ${LOGFILE}
   echo "\n$0 ended at $(date +"%Y-%m-%d:%H:%M:%S")"   >> ${LOGFILE}
   echo "####################################"  >> ${LOGFILE}
   exit 2
else 
   echo "\nNo ORACLE errors found."   >> ${LOGFILE}
fi

12c 或更高

如果您在此版本中，您可能希望使用功能set markup csv 来生成文件。

FILE="CASE.csv"
export dest_loc=/dest/loc
export LOGFILE=$LOG/100.$NOW_TS.log
echo "$0 started at $(date +"%Y-%m-%d:%H:%M:%S")" > ${LOGFILE}
sqlplus -s $DB_LOGIN << EOSQL >> ${LOGFILE}
WHENEVER SQLERROR EXIT FAILURE;
WHENEVER OSERROR EXIT FAILURE;
SET echo OFF
SET feedback OFF    
SET SQLBLANKLINES ON
SET PAGESIZE 50000
SET LINESIZE 650
SET TERMOUT OFF
SET MARKUP CSV ON DELIMITER "|"
SPOOL $dest_loc/$FILE
@$SRC/sql_to_run.sql
SPOOL OFF
EOSQL
rc=$?
if [ ${rc} -ne 0 ];
then
   echo "\nThere has been an ORACLE error. RC = $RC"   >> ${LOGFILE}
   echo "\n$0 ended at $(date +"%Y-%m-%d:%H:%M:%S")"   >> ${LOGFILE}
   echo "##########################################"   >> ${LOGFILE}
   exit 2;
else 
   echo "\nNo ORACLE errors found."   >> ${LOGFILE}
fi
