我正面临一个问题，我希望在表格中看到一个字段的总和。
select sum(ve.[Cost Posted to G_L]) CPGL, sum(ve.[Expected Cost Posted to G_L]) ECPGL from [ICTL | HYDERABAD$Value Entry] ve
left join [ICTL | HYDERABAD$G_L - Item Ledger Relation] glr on
ve.[Entry No_] = glr.[Value Entry No_]
left join [ICTL | HYDERABAD$G_L Entry] ge on
glr.[G_L Entry No_] = ge.[Entry No_]
left join [ICTL | HYDERABAD$G_L Account] ga on
ge.[G_L Account No_] = ga.No_
where ga.No_ = '200610' and ve.[Posting Date] < '03-01-2017'
group by ga.No_
以下是示例 表ve
Entry No. | CPGL | ECPGL | Posting Date
1 10 0 01-02-2017
