【问题描述】：

我正在使用这段代码，一旦我运行它，我得到 。我不知道代码中的哪些地方需要更改或不正确。你能帮我解决它吗？

CurrentDb.Execute "UPDATE WORKED_HOURS " & _
" set EMPLOYEE_ID=" & `enter code here`Me.cboEmployeeID & _
", SET FIRST_NAME='" & Me.FIRST_NAME & "'" & _
", SET LAST_NAME='" & Me.LAST_NAME & "'" & _
", Set WORK_ORDER_NO='" & Me.cboWorkOrderNo & "'" & _
", SET PROJECT_TITLE='" & Me.txtProjectTitle & "'" & _
", SET WORKED_DATE='" & Me.txtWorkedDate & "'" & _
", SET TIME_STARTED='" & Me.txtTimeStarted & "'" & _
", SET TIME_FINISHED='" & Me.txtTimeFinished & "'" & _
", SET WEEK_ENDING='" & Me.txtWeekEnding & "'" & _
" where EMPLOYEE_ID=" & Me.cboEmployeeID.Tag

【问题讨论】：

在您的第二行...enter code here 是什么意思？复制到您的 SO 问题时这是一个错误吗？您可能应该尝试搜索运行时错误 3314 并查看它发生的原因并首先尝试。

更新 SQL 语句应该只保留 一个 SET 命令。用逗号分隔每个表达式，用引号将字符串括起来，用井号括起来日期等。最好使用参数化。

【参考方案1】：

您（还）需要正确格式化您的日期和时间值。

一种方法是应用此功能。用法见内联 cmets：

' Converts a value of any type to its string representation.
' The function can be concatenated into an SQL expression as is
' without any delimiters or leading/trailing white-space.
'
' Examples:
'   SQL = "Select * From TableTest Where [Amount]>" & CSql(12.5) & "And [DueDate]<" & CSql(Date) & ""
'   SQL -> Select * From TableTest Where [Amount]> 12.5 And [DueDate]< #2016/01/30 00:00:00#
'
'   SQL = "Insert Into TableTest ( [Street] ) Values (" & CSql(" ") & ")"
'   SQL -> Insert Into TableTest ( [Street] ) Values ( Null )
'
' Trims text variables for leading/trailing Space and secures single quotes.
' Replaces zero length strings with Null.
' Formats date/time variables as safe string expressions.
' Uses Str to format decimal values to string expressions.
' Returns Null for values that cannot be expressed with a string expression.

【参考方案2】：

几乎每一种 SQL 方言中的更新语句都不允许使用多个 SET 命令，而只允许一个包含多个用逗号分隔的表达式的命令。考虑这样做并根据数据类型用引号 (strings)、井号 (dates) 或空字符 (integer) 正确括起来：

CurrentDb.Execute "UPDATE WORKED_HOURS " _
         & "  SET EMPLOYEE_ID=" & Me.cboEmployeeID _
         & "  , FIRST_NAME='" & Me.FIRST_NAME & "'" _
         & "  , LAST_NAME='" & Me.LAST_NAME & "'" _
         & "  , WORK_ORDER_NO='" & Me.cboWorkOrderNo & "'" _
         & "  , PROJECT_TITLE='" & Me.txtProjectTitle & "'" _
         & "  , WORKED_DATE=#" & Me.txtWorkedDate & "#" _
         & "  , TIME_STARTED=#" & Me.txtTimeStarted & "#" _
         & "  , TIME_FINISHED=#" & Me.txtTimeFinished & "#" _
         & "  , WEEK_ENDING=#" & Me.txtWeekEnding & "#" _
         & "  WHERE EMPLOYEE_ID=" & Me.cboEmployeeID.Tag

但为了获得最佳实践，请考虑使用参数化的 querydef，它甚至可以避免所需的引号或井号。 Jet/ACE SQL 允许使用PARAMETERS 子句声明参数。

Dim qdef As querydef

strSQL = "PARAMETERS [EMPLOYEE_ID] Integer, [FIRST_NAME] Text(255)," _
          & " [LAST_NAME] Text(255), [WORK_ORDER_NO] Text(255)," _
          & " [PROJECT_TITLE] Text(255), [WORKED_DATE] Datetime," _
          & " [TIME_STARTED] Datetime, [TIME_FINISHED] Datetime," _ 
          & " [WEEK_ENDING] Datetime;" 
          & " UPDATE WORKED_HOURS " _
          & " SET EMPLOYEE_ID = [EMPLOYEE_ID]" _
          & "  , FIRST_NAME = [FIRST_NAME]" _
          & "  , LAST_NAME = [LAST_NAME] " _
          & "  , WORK_ORDER_NO = [WORK_ORDER_NO] " _
          & "  , PROJECT_TITLE = [PROJECT_TITLE]" _
          & "  , WORKED_DATE = [WORKED_DATE]" _
          & "  , TIME_STARTED = [TIME_STARTED]" _
          & "  , TIME_FINISHED = [TIME_FINISHED]" _
          & "  , WEEK_ENDING = [WEEK_ENDING]" _
          & "  WHERE EMPLOYEE_ID = [EMPLOYEE_ID]"

Set qdef = Currentdb.CreateQueryDef("", strSQL)

qdef!EMPLOYEE_ID = Me.cboEmployeeID
qdef!FIRST_NAME =  Me.FIRST_NAME
qdef!LAST_NAME = Me.LAST_NAME
qdef!WORK_ORDER_NO = Me.cboWorkOrderNo
qdef!PROJECT_TITLE = Me.txtProjectTitle
qdef!WORKED_DATE = Me.txtWorkedDate
qdef!TIME_STARTED = Me.txtTimeStarted
qdef!TIME_FINISHED = Me.txtTimeFinished 
qdef!WEEK_ENDING = Me.txtWeekEnding

qdef.Execute

Set qdef = Nothing
