BUG #: 351486 (SHILOH_BUGS)
Using the SQL Distributed Management Objects (DMO) BulkCopy object to import data into a SQL Server table that contains a column with a space embedded in the column name may fail with no rows copied.
By default, the BulkCopy object uses a second connection which does not inherit properties, such as QuotedIdentifiers, from the original connection.
To resolve this problem, obtain the latest service pack for SQL Server 2000. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
INF: How to Obtain the Latest SQL Server 2000 Service Pack
You can work around this problem in the following ways:
- Make sure that the SQL-DMO BulkCopy object reuses the existing connection by setting the UseExistingConnection property to True.
- Remove the embedded space in the column name.
Microsoft has confirmed that this is a problem in SQL Server 2000. This problem was first corrected in SQL Server 2000 Service Pack 1.
Steps to Reproduce Behavior
- Create the source and destination SQL Server tables in the sample Northwind database:
create table BulkCopyFrom ( c1 int)gocreate table BulkCopyTo ( [c1 copy] int )goinsert BulkCopyFrom values (1)
- Use the following Microsoft Visual Basic/SQL-DMO code to demonstrate the problem:
This code results in 0 rows imported into the destination table BulkCopyTo.
Public Sub Main()On Error GoTo ErrHandlerDim server As New SQLDMO.SQLServerDim blk As New SQLDMO.BulkCopyDim db As SQLDMO.DatabaseDim tblSrc As SQLDMO.TableDim tblDst As SQLDMO.TableDim lRowsExported As LongDim lRowsImported As Longserver.LoginSecure = Trueserver.EnableBcp = Trueserver.Connect "." 'Uses the default SQL Server instanceserver.QuotedIdentifier = TrueSet db = server.Databases("northwind")Set tblSrc = db.Tables("BulkCopyFrom")Set tblDst = db.Tables("BulkCopyTo")'blk.UseExistingConnection = True 'Uncomment this line to reuse connectionblk.DataFilePath = "C:\TEMP\exported.dat"blk.ErrorFilePath = "C:\TEMP\exported.err"blk.LogFilePath = "C:\TEMP\exported.log"blk.DataFileType = SQLDMODataFile_NativeFormatblk.UseBulkCopyOption = Trueblk.IncludeIdentityValues = Trueblk.SetCodePage SQLDMOBCP_RAWlRowsExported = tblSrc.ExportData(blk)MsgBox "Exported " & lRowsExported & " rows"blk.ErrorFilePath = "C:\TEMP\imported.err"blk.LogFilePath = "C:\TEMP\imported.log"lRowsImported = tblDst.ImportData(blk)MsgBox "Imported " & lRowsImported & " rows"server.DisConnectSet blk = NothingSet server = NothingExit SubErrHandler:MsgBox "Error " & Err.Number & vbclr & Err.DescriptionResume NextEnd Sub
To work around the problem, uncomment the code line to reuse the existing connection.
