采用SHELL，通过SQLLOAD导入一定格式的txt文件至数据库中
1。 准备工作，window中可直接通过sqlload直接导入文件，linux下，需要有sqlload的相关软件。
2。 SQL脚本（MID_DFDZ.ctl）
LOAD DATA
INTO TABLE MID_T0_TRANS
truncate
FIELDS TERMINATED BY '|'
(
stldate,
merno,
termno,
pan,
transamt,
refno,
termssn,
batno,
transdate,
workdate,
fee
)
3.shell脚本（getDFDZ.sh）
#!/bin/bash
if [ $# -lt 2 ]
then
echo "miss arguments"
exit -1
fi
#parameters

SEQ_NO=$2
