Sql 使用子查询的查询表达式中出现语法错误

我遇到以下错误：-

SELECT
(
SELECT Sum(tbl_allTransactions.transAmount) AS SumOftransAmount
FROM tbl_allTransactions
WHERE (((tbl_allTransactions.[transType])='Expense')) OR (((tbl_allTransactions.[transType])='Budget') AND ((tbl_allTransactions.[transMonth])=[@transMonth]))
GROUP BY tbl_allTransactions.transMonth
,

SELECT Sum(tbl_allTransactions.transAmount) AS SumOftransAmount
FROM tbl_allTransactions
WHERE (((tbl_allTransactions.[transType])='Expense')) OR (((tbl_allTransactions.[transType])='Budget') AND ((tbl_allTransactions.[transMonth])=[@transMonth]))
GROUP BY tbl_allTransactions.transMonth
)

FROM tbl_allTransactions WHERE (((tbl_allTransactions.[userID])=[@userID]))

原始代码在第一个子查询中缺少右括号。通过将transType条件语句从2条语句合并为1条语句，代码也得到了简化。为了提高可读性，去掉了额外的括号。还将列别名添加到每个子查询的输出中。因为两个查询都呈现相同的数据，所以第二列称为SumOftransAmount2

当我运行单个子查询时，它工作正常，但当我执行两个子查询时，如上面给出的错误。你能共享错误文本吗？我如何共享错误快照？复制并粘贴错误消息到你的帖子@AishwarCNigamSystem.Data.OleDb.OLEDBEException 0x80040E14查询表达式“选择Sumtbl_allTransactions.transAmount作为tbl_allTransactions中tbl_allTransactions的交易金额之和，其中tbl_allTransactions.[transType]='Expense'或tbl_allTransactions.[transType]='Budget'和tbl_allTransactions.[transMonth]=[@transMonth]GROUP]。在System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandlingOleDbHResult hr中，在System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResulttagDBPARAMS dbParams中，对象和RealTureSturt在Stase.Dela.
