我有一个Excel表,想要更新第12列Excel引用的SQL Server表记录的日期值(使用getdate函数)。
我的代码如下,但我看到了:
运行时错误3001参数类型错误或超出可接受的范围或彼此冲突。
在SQL表中,MODIFIEDDATE字段是datetime类型,MAINREF字段是整数类型。
Private Sub CommandButton2_Click()
Dim conn2 As New ADODB.Connection
Dim rst2 As New ADODB.Recordset
Dim j As Integer
conn2.ConnectionString = "Provider=SQLOLEDB.1;Password=abc;Persist Security Info=True;User ID=sa;Initial Catalog=logodb;Data Source=A3650;Use Procedure for Prepare=1;Auto"
conn2.Open
For j = 0 To 1900
If Sayfa1.Cells(j + 4, 12) = "" Then
Sayfa1.Cells(j + 4, 13) = "empty"
Else
rst2.Open "UPDATE T_015 SET MODIFIEDDATE=GETDATE() WHERE MAINREF='" & Sayfa1.Cells(j + 4, 12) & "'", conn, 1, 3
rst2.Close
End If
Next j
End Sub
我尝试更改SQL查询,如(CInt(cell.value))
rst2.Open "UPDATE T_015 SET MODIFIEDDATE=GETDATE() WHERE MAINREF='" & CInt(Sayfa1.Cells(j + 4, 12)) & "'", conn, 1, 3
但是,它没有用。
答案 0 :(得分:0)
ADODB.Recordset对象不应用于UPDATE查询。直接从ADODB.Connection
执行SQL语句Dim conn2 As New ADODB.Connection
conn2.ConnectionString = "Provider=SQLNCLI11;Server=MYSERVER;Database=TMP;UID=sa;password=abc;"
conn2.Open
conn2.Execute "UPDATE T_015 SET MODIFIEDDATE=GETDATE() WHERE MAINREF=1"

有两种方法可以满足您的要求,似乎您正在混合这两种方式。
一种方法是一次更新一个记录,为此,您可以使用Connection
对象,或者更优选地使用Command
对象。我说最好是因为参数化命令是一种更健壮的SQL执行方式。如果您打算使用SQL,那么您可能应该阅读它。你这样做的方式如下:
Public Sub ParameterisedProcedure()
Dim conn As ADODB.Connection
Dim cmd As ADODB.Command
Dim prm As ADODB.Parameter
Dim v As Variant
Dim j As Integer
'Read the sheet data
v = Sayfa1.Range("L4", "M1904").Value2
'Open the database connection
Set conn = New ADODB.Connection
conn.ConnectionString = "Provider=SQLOLEDB.1;" & _
"Password=abc;" & _
"Persist Security Info=True;" & _
"User ID=sa;" & _
"Initial Catalog=logodb;" & _
"Data Source=A3650;" & _
"Use Procedure for Prepare=1;" & _
"Auto"
conn.Open
'Loop through the values to update records
For j = 1 To UBound(v, 1)
If IsEmpty(v(j, 1)) Then
v(j, 2) = "empty"
Else
'Create the parameterised command
Set cmd = New ADODB.Command
cmd.ActiveConnection = conn
cmd.CommandType = adCmdText
cmd.CommandText = "UPDATE T_015 " & _
"SET MODIFIEDDATE=? " & _
"WHERE MAINREF=?"
prm = cmd.CreateParameter(Type:=adDate, Value:=Now)
cmd.Parameters.Append prm
prm = cmd.CreateParameter(Type:=adInteger, Value:=v(j, 1))
cmd.Parameters.Append prm
cmd.Execute
End If
Next
'Write the updated values
Sayfa1.Range("L4", "M1904").Value = v
'Close the database
Set prm = Nothing
Set cmd = Nothing
conn.Close
End Sub
另一种方法是使用Transactions
,你确实会使用Recordset
(就像你已经完成的那样)。在这种情况下,我建议这是更好的方法,因为一次执行一个命令(如上面的代码)是非常慢的。更快捷的方法是在一个事务中提交所有更新。与参数化命令一样,输入SQL命令文本的恶意字符串也是安全的。代码如下所示:
Public Sub TransactionProcedure()
Dim conn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim cmdText As String
Dim v As Variant
Dim j As Integer
'Read the sheet data
v = Sayfa1.Range("L4", "M1904").Value2
'Open the database connection
Set conn = New ADODB.Connection
conn.ConnectionString = "Provider=SQLOLEDB.1;" & _
"Password=abc;" & _
"Persist Security Info=True;" & _
"User ID=sa;" & _
"Initial Catalog=logodb;" & _
"Data Source=A3650;" & _
"Use Procedure for Prepare=1;" & _
"Auto"
conn.Open
'Retrieve the data
Set rs = New ADODB.Recordset
cmdText = "SELECT * FROM T_015"
rs.Open cmdText, conn, adOpenStatic, adLockReadOnly, adCmdText
'Loop through the values to update the recordset
On Error GoTo EH
conn.BeginTrans
For j = 1 To UBound(v, 1)
If IsEmpty(v(j, 1)) Then
v(j, 2) = "empty"
Else
'Find and update the record
rs.Find "MAINREF=" & CStr(v(j, 1))
If Not rs.EOF Then
rs!ModifiedDate = Now
rs.Update
End If
End If
Next
conn.CommitTrans
'Write the updated values
Sayfa1.Range("L4", "M1904").Value = v
'Close the database
rs.Close
conn.Close
Exit Sub
EH:
conn.RollbackTrans
Sayfa1.Range("L4", "M1904").Value = v
rs.Close
conn.Close
MsgBox Err.Description
End Sub
