Totaling Cash Values with Date Filtering in SQL

As you mentioned, you have a SQL statement that calculates the total cash for each unique transaction ID using the following line:

select sum(cash) from Table a where a.branch = p.branch and a.transID = p.transID) TotalCash

To modify this statement to only total cash values that have a value date within the last month, you can update it in the following way:

select SUM(CASE WHEN ValueDate > @startMonthDate THEN cash ELSE 0 END)
from Table a where a.branch = p.branch and a.transID = p.transID) TotalMonthCash

SUM()

• Performance Optimization:
• As a side note, if the performance of your query becomes an issue, consider rewriting it using a JOIN and小組而不是依賴子查詢。這可能會改善執行時間。
