BlackListDay.ctl:

LOAD DATA
INFILE '${DATAFILE}'                                   ---------数据文件，即txt文件
badfile 'ct_blacklistday_info.bad'
Append INTO TABLE fujz_blacklist_temp       -----表名
FIELDS TERMINATED BY '|'                             ------数据用|分割
TRAILING NULLCOLS
(
  ID_TYPE, 							------表中字段
  ID_ICCID, 
  OP_TIME "to_date(:OP_TIME,'YYYY-MM-DDHH24:MI:SS')"

DATAFILE35="$HOME/work/fujza/BLACK35_201211.txt"

export DATAFILE35
sqlldr ${DBNAME}/${DBPWD}@${SID} log=${HOME}/work/fujza/BlackListDay2.log control=${HOME}/work/fujza/BlackListDay35.ctl streamsize=25600000
	echo "sqlldr2 end"
export DATAFILE
sqlldr ${DBNAME}/${DBPWD}@${SID} log=${HOME}/work/fujza/BlackListDay.log control=${HOME}/work/fujza/BlackListDay.ctl streamsize=25600000
