来自UPDATE语句的运行时错误3144

Question

CurrentDb.Execute "UPDATE Transaction SET receipt_id=" & txtreceipt_id & ", tdate=" & txttdate & ",total_cost=" & txttotal_cost & ",total_disc=" & txttotal_disc & " WHERE receipt_id=" & txtreceipt_id & " "

我得到运行时3144语法错误。似乎无法找到错误。

Answer 1

所以看起来语法稍微有点......可能有助于将代码分成几部分......我无法测试此解决方案但是尝试这个（这完全取决于数据类型） ：

CurrentDb.Execute "UPDATE Transaction " & _
" SET receipt_id = '" & txtreceipt_id & "'" & _
", tdate = "  & txttdate & "" & _
", total_cost = " & txttotal_cost & "" & _
", total_disc = " & txttotal_disc & "" & _
" WHERE receipt_id = '" & txtreceipt_id & "'"

如果txreceipt_id是一个数字，请尝试：

CurrentDb.Execute "UPDATE Transaction " & _
" SET receipt_id = " & txtreceipt_id & "" & _
", tdate = " & txttdate & "" & _
", total_cost = " & txttotal_cost & "" & _
", total_disc = " & txttotal_disc & "" & _
" WHERE receipt_id = " & txtreceipt_id & ""

Answer 2

考虑使用带有MS Access“parameterized query的QueryDefs来准确指定绑定值的数据类型，并避免连接和引用包装，这会使代码难以维护。根据{{​​1}}子句中的需要调整以下类型（在Access SQL中符合）。

SQL （仅保存为MS Access存储查询一次）

PARAMETERS

VBA （将值动态绑定到参数占位符）

PARAMETERS [txtreceipt_id_PARAM] LONG, [txttdate_PARAM] DATE,
           [txttotal_cost_PARAM] DOUBLE, [txttotal_disc_PARAM] DOUBLE;
UPDATE [Transaction] 
SET receipt_id = [txtreceipt_id_PARAM], 
    tdate = [txttdate_PARAM],
    total_cost = [txttotal_cost_PARAM], 
    total_disc = [txttotal_disc_PARAM]
WHERE receipt_id = [txtreceipt_id_PARAM];
