MS-Access - 您尝试执行不包含指定聚合函数的查询，还有其他任何解决方案吗？

Question

 SQL = "TRANSFORM FIRST(a.TimeStamp1) "
 SQL = SQL & "SELECT a.DealName, DealList.SettlementDate "
 SQL = SQL & "FROM DealList, DealStepLog a INNER JOIN DealStepMasterData b on b.StepName = a.DealStep "
 SQL = SQL & "WHERE b.StepClassification = 'Compliance' "
 SQL = SQL & "GROUP BY DealName "
 SQL = SQL & "PIVOT dealStep "

我知道我必须在GROUP BY部分放置'SettlementDate'，但我不想按settlementDate，任何其他选项进行分组？

Answer 1

然后你必须使用其中一个聚合函数，例如其中一个：

First(SettlementDate)
Last(SettlementDate)
Max(SettlementDate)
Avg(SettlementDate)
Min(SettlementDate)
