系統(tǒng)中有前臺(tái)服務(wù)器和后臺(tái)服務(wù)器，前臺(tái)的銷(xiāo)售數(shù)據(jù)是直接傳到前臺(tái)服務(wù)器的，而后臺(tái)是通過(guò)作業(yè)定時(shí)從前臺(tái)獲取銷(xiāo)售記錄的。分析原因：

1 后臺(tái)定時(shí)執(zhí)行沒(méi)有執(zhí)行，由于數(shù)據(jù)庫(kù)的代理服務(wù)沒(méi)有啟動(dòng)或者人為的將作業(yè)停了，導(dǎo)致后臺(tái)定時(shí)執(zhí)行沒(méi)有執(zhí)行；處理辦法，啟動(dòng)作業(yè)，開(kāi)啟數(shù)據(jù)庫(kù)代理的服務(wù)

2 銷(xiāo)售拆分問(wèn)題：銷(xiāo)售數(shù)據(jù)傳到后臺(tái)后，系統(tǒng)會(huì)進(jìn)行拆分，拆分完成后，才會(huì)在相關(guān)報(bào)表中體現(xiàn)，才會(huì)真正算銷(xiāo)售。銷(xiāo)售拆分出錯(cuò)是絕大多少銷(xiāo)售沒(méi)有傳到后臺(tái)的原因。導(dǎo)致這樣的情況一般有下面幾個(gè)情況 1、有人修改tb_trans_status，導(dǎo)致記錄已拆分記錄錯(cuò)誤處理辦法：修改 tb_trans_status中銷(xiāo)售拆分的id,可以找最大tb_o_sg.c_identity；2、前臺(tái)硬件故障，銷(xiāo)售重復(fù)傳送，特征：tb_o_sale.c_guid重復(fù)處理辦法：刪除重復(fù)的c_guid；3、商品后臺(tái)不存在，這個(gè)一般由于后臺(tái)刪除商品后，沒(méi)有及時(shí)傳到前臺(tái)，前臺(tái)正好做了銷(xiāo)售，處理辦法：刪除改流水，用正確的商品編碼銷(xiāo)售；4、商品在一個(gè)門(mén)店存在2個(gè)部門(mén)，銷(xiāo)售拆分時(shí)不知道是哪個(gè)部門(mén)算哪個(gè)部門(mén)的銷(xiāo)售，處理辦法：刪除錯(cuò)誤的部門(mén)。

輔助查詢語(yǔ)句：

/*tb_o_sale.c_guid重復(fù)*/

select * from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='銷(xiāo)售分拆')
and exists (select * from tb_o_sg (nolock) where tb_o_sale.c_guid=tb_o_sg.c_guid)

/*一個(gè)商品在一個(gè)門(mén)店存在2個(gè)部門(mén)*/

select c_store_id,c_gcode,COUNT(*) as c_count
from(
select tb_o_sale.c_gcode,tb_gdsstore.c_store_id,tb_gdsstore.c_adno
from tb_o_sale(nolock),tb_gdsstore(nolock)
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='銷(xiāo)售分拆')
and tb_o_sale.c_gcode=tb_gdsstore.c_gcode
group by tb_o_sale.c_gcode,tb_gdsstore.c_store_id,tb_gdsstore.c_adno
)a
group by c_store_id,c_gcode
having COUNT(*)>1

/*商品編碼后臺(tái)不存在*/

select * from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='銷(xiāo)售分拆')
and not exists (select * from tb_gds (nolock) where tb_o_sale.c_gcode=tb_gds.c_gcode)

and c_flag='G'

[此貼子已經(jīng)被作者于2010-12-12 21:10:19編輯過(guò)]

還有一種：

select c_guid from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='銷(xiāo)售分拆')
group by c_guid

having count(*)>1

還有一種情況，沒(méi)有可用的資源了，比方磁盤(pán)空間或者內(nèi)存設(shè)置過(guò)低或者本身服務(wù)器內(nèi)存就比較小

導(dǎo)致服務(wù)被終止，傳輸無(wú)法運(yùn)行，我這出現(xiàn)過(guò)類(lèi)似的問(wèn)題

處理方法：

1 先將數(shù)據(jù)做好備份

2 刪除重復(fù)數(shù)據(jù)

3 觀察作業(yè)是否成功

以/*tb_o_sale.c_guid重復(fù)*/為例：

第一步：

select * into tb_o_sale_20110815

from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='銷(xiāo)售分拆')
and exists (select * from tb_o_sg (nolock) where tb_o_sale.c_guid=tb_o_sg.c_guid)

第二步：

delete from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='銷(xiāo)售分拆')
and exists (select * from tb_o_sg (nolock) where tb_o_sale.c_guid=tb_o_sg.c_guid)

第三步：

查看作業(yè)是否成功，實(shí)時(shí)銷(xiāo)售監(jiān)察是否正確

如果不想讓錯(cuò)誤數(shù)據(jù)影響當(dāng)天銷(xiāo)售，可以建立作業(yè)，將錯(cuò)誤數(shù)據(jù)做好備份，讓剩余數(shù)據(jù)正常拆分，建議一天晚上執(zhí)行一次
