Question

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

Answer 1

考虑到您的问题只涉及bash，您有以下错误：

1 - 你会为此做什么：

startdate=...
set startdate=...

2 - 你的语法在bash中的赋值是错误的;你不应该有空格：

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

3 - for循环的这种语法错误;猜你想要一个while循环：

for ($startdate <= $enddate)  *wrong*
do ...
done

while (( $startdate <= $enddate )); do
    ...
done

4 - 你对此有何期待：

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

您可能会尝试按1 day减少$ startdate的值，因为您需要执行此操作：

startdate=$(date -d $startdate' -1 days' +"%y-%m-%d")
