以下sql代码将插入文本文件中，作为input.txt的输入：

insert into t_agg_sgsn_gprs_usage

select

served_imsi as imsi,

served_msisdn as msisdn,

NVL(cell_identity,'-1') as cell_id,

NVL(trim(to_char(location_area_code,'99999999')),'UNKNOWN'),

substr(served_imei,1,8) tac_code,

to_char(to_timestamp(record_opening_time,'YYYYMMDDHH24MISS'),'YYYYMMDD')

as call_dt,

'ajay' as loaded_dt,

count(1) as cdr_count,

sum(data_volume_uplink) as uploaded_data_volume,

sum(data_volume_downlink) as downloaded_data_volume,

case

when substr(imsi,6,2)='65'

then substr(imsi,1,9)

else substr(imsi,1,5)

end imsi_prefix

from

t_cdrc_sgsn_pdp_18

where loaded_dt LIKE 'ajay%' AND trim(served_imsi) != ''

AND trim(served_msisdn) != '' AND trim(served_imei) != ''

group by imsi, msisdn, tac_code, cell_id, location_area_code, call_dt;

我正在编写一个unix脚本，它应该为输出提供加1的日期，并附加到一个sql文件(changer.sql)，直到指定的日期。

insert into t_agg_sgsn_gprs_usage

select

served_imsi as imsi,

served_msisdn as msisdn,

NVL(cell_identity,'-1') as cell_id,

NVL(trim(to_char(location_area_code,'99999999')),'UNKNOWN'),

substr(served_imei,1,8) tac_code,

to_char(to_timestamp(record_opening_time,'YYYYMMDDHH24MISS'),'YYYYMMDD') as call_dt,

'2012-10-17' as loaded_dt,

count(1) as cdr_count,

sum(data_volume_uplink) as uploaded_data_volume,

sum(data_volume_downlink) as downloaded_data_volume,

case when substr(imsi,6,2)='65' then substr(imsi,1,9) else substr(imsi,1,5) end imsi_prefix

from

t_cdrc_sgsn_pdp_18

where loaded_dt LIKE '2012-10-17%' AND trim(served_imsi) != '' AND trim(served_msisdn) != '' AND trim(served_imei) != ''

group by imsi, msisdn, tac_code, cell_id, location_area_code, call_dt;

insert into t_agg_sgsn_gprs_usage

select

served_imsi as imsi,

served_msisdn as msisdn,

NVL(cell_identity,'-1') as cell_id,

NVL(trim(to_char(location_area_code,'99999999')),'UNKNOWN'),

substr(served_imei,1,8) tac_code,

to_char(to_timestamp(record_opening_time,'YYYYMMDDHH24MISS'),'YYYYMMDD') as call_dt,

'2012-10-18' as loaded_dt,

count(1) as cdr_count,

sum(data_volume_uplink) as uploaded_data_volume,

sum(data_volume_downlink) as downloaded_data_volume,

case when substr(imsi,6,2)='65' then substr(imsi,1,9) else substr(imsi,1,5) end imsi_prefix

from

t_cdrc_sgsn_pdp_18

where loaded_dt LIKE '2012-10-18%' AND trim(served_imsi) != '' AND trim(served_msisdn) != '' AND trim(served_imei) != ''

group by imsi, msisdn, tac_code, cell_id, location_area_code, call_dt;

继续递增并附加到changer.sql文件中，直到指定的结束日期。

以下是我到目前为止的情况，但仍未产生预期的结果：

startdate = `date +"%y-%m-%d"`

set startdate = 2012-10-17

enddate = `date “+%y-%m-%d`

set enddate = 2012-12-22

for($startdate <= $enddate)

do

for file in $(grep -il "ajay" input.txt)

do

sed -e "s/ajay/$startdate/ig" $file >> changer.sql

done

$startdate --startdate="-1 days ago"

done
