我遇到以下链接:
http://www.informit.com/guides/content.aspx?g=sqlServer&seqnum=135
在其中,他们列出了相对简单的代码以查询Excel VBA的SQL数据库。
' Declare the QueryTable object
Dim qt As QueryTable
' Set up the SQL Statement
sqlstring = "select au_fname, au_lname from authors"
' Set up the connection string, reference an ODBC connection
' There are several ways to do this
' Leave the name and password blank for NT authentication
connstring = _
"ODBC;DSN=pubs;UID=;PWD=;Database=pubs"
' Now implement the connection, run the query, and add
' the results to the spreadsheet starting at row A1
With ActiveSheet.QueryTables.Add(Connection:=connstring, Destination:=Range("A1"), Sql:=sqlstring)
.Refresh
End With
'Save and close the macro, and run it from the same menu you accessed in step 2.
这很好。但是,我希望能够将一个值作为变量撤回,而不是将其倾倒为Excel。
有人可以帮我吗?我已经尝试寻找Excel VBA SQL教程,但是看来我发现的一半代码不起作用(也许是因为我不够理解它)。
解决方案
您可以使用ADO,例如:
''Reference: Microsft ActiveX Data Objects x.x Library
Dim cmd As New ADODB.Command
Dim cn As New ADODB.Connection
Dim param1 As New ADODB.Parameter
Dim rs As ADODB.Recordset
With cn
.Provider = "SQLOLEDB"
''See also http://connectionsstrings.com
.ConnectionString = "Data Source=Server;Initial Catalog=test;Trusted_Connection=Yes"
.Open
End With
Set param1 = cmd.CreateParameter("@SiteID", adBigInt, adParamInput)
param1.Value = 1
cmd.Parameters.Append param1
With cmd
.ActiveConnection = cn
''Stored procedure
.CommandText = "spSiteInformation_Retrieve"
.CommandType = adCmdStoredProc
Set rs = .Execute
End With
For Each f In rs.Fields
Debug.Print f.Name; " "; f
Next
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
