Query SQL Server table with RowVersion - sql-server

Question

I am querying SQL Server from VBA using ADODB. All of my tables have RowVersion (timestamp/varbinary) columns. Since VBA doesn't support the varbinary type, I convert the RowVersion to a string from a SQL Server function. A simple query will look like:
sql = "SELECT NameValueListID, dbo.RowVersionToString(RowVersion) AS RowVersion FROM NameValueLists WHERE NameValueListID=1
To get the data onto a sheet, I first tried range.CopyFromRecordset. This worked until I included the above function in the sql call. Adding the RowVersionToString function caused the recordset to return what seems like a random set of data - less rows than excepted and fewer column than I asked for. Never could figure that one out. I then used rs.GetRows which returned the expected data and I could use range.value = rsData successfully. Below is a sample call that works.
Private Sub Test_Scratch()
Dim rs As ADODB.Recordset
Dim sqlCmd As New ADODB.Command
Dim sqlConnection As ADODB.Connection
Dim sql As String
Dim rsData() As Variant
Set sqlConnection = New ADODB.Connection
sqlConnection.Open ModSQL.GetConnectionStringByStage(wsSetup.Range("suAppStage"))
sql = "SELECT NameValueListID, dbo.RowVersionToString(RowVersion) AS RowVersion FROM NameValueLists WHERE NameValueListID=1"
Set sqlCmd.ActiveConnection = sqlConnection
sqlCmd.CommandText = sql
Set rs = sqlCmd.Execute
rs.MoveFirst
rsData = rs.GetRows
End Sub
I then added a second varbinary column to the query (it's not a RowVersion but is of the same type). So the sql will look like:
sql = "SELECT NameValueListID, dbo.RowVersionToString(RowVersion) AS RowVersion, dbo.RowVersionToString(LastItemRowVersion) AS LastItemRowVersion FROM NameValueLists WHERE NameValueListID=1
After the call, the recordset rs has all the data, but rsData has "Empty" for the first varbinary column. The order doesn't matter. Only the last varbinary column has a value, the other is always "Empty" in the rsData array.

I guess,more could anser your question if you showed your code of user function RowVersionToString.What is the definition of argument of RowVersionToString?It might be that the argument "RowVersion" was interpreted to a data type not but a colmun name.
sql = "SELECT NameValueListID, dbo.RowVersionToString(NameValueLists.RowVersion) AS RowVersion, dbo.RowVersionToString(LastItemRowVersion) AS LastItemRowVersion FROM NameValueLists WHERE NameValueListID=1
