Question

我在shell脚本中有动态控制文件，如下所示

`echo 'LOAD DATA' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'APPEND' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'INTO TABLE TJX_SCR_UPLOAD_HEADER' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'WHEN FILE_RECORD_DESCRIPTOR = ' \'FHEAD\'  >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'FIELDS TERMINATED BY ","' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'TRAILING NULLCOLS' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo '(' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'FILE_RECORD_DESCRIPTOR   position(1),' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'LINE_NO                  FILLER,' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'SCHEDULE_NO              ,' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'SCHEDULE_DATE_TIME       date' \'YYYYMMDD\' ',' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'UPLD_TIME_STAMP          sysdate,' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'SEQ_NO                   "' ${exec_seq} '",' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'FILENAME                 CONSTANT ' \'$FILENAME\'  ',' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo 'STATUS                   CONSTANT "UPLOADED"' >> $CTL_DIR/tjx_sc_req_upld.ctl
   echo ')' >> $CTL_DIR/tjx_sc_req_upld.ctl`

使用上面的代码，shell脚本也运行正常。但是当我在OPTIONALLY ENCLOSED BY '"'旁边添加fields terminated by时，如下所示

echo 'FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' ' >> $CTL_DIR/tjx_sc_req_upld.ctl

我收到语法错误

./tjx_sc_req_upld.ksh: line 109: syntax error at line 216: `(`' unexpected

当我删除可选的封闭时我不会收到错误。

你最终得到了无与伦比的报价。您需要进行一些转义才能获得文字单引号：

echo 'FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '\''"'\'' ' >> $CTL_DIR/tjx_sc_req_upld.ctl

您可以切换引号，使其不那么难看：

echo "FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' " >> $CTL_DIR/tjx_sc_req_upld.ctl

sqlldr错误，可选择用'''括起来
