in reply to DBI don't fetch my data...or at least not all records

Hi, perhaps you should try 'SELECT 'foo' and see what happens. ( no DUAL in MSSQL...). Regards, Karl.

Update: I think it is not a bad idea to check your connection with a simple query.

    Hi thanks for trying to help out. Well the connection works fine, as stated bofore if I use the same connection towards another table in the same db, with the same user it works. I have also checked permission on the table and there are no strange permissions and I use trused user on both ODBC and when connection via enteprise manager. But in enterprise manager I get a result

      Update:

      Yes, but do you fetch a result if you say SELECT 'foo'? Please feel free to provide more information about what you want to do. I then can try to repeat this with my MSSQL...

      I could not repeat it (i'm using SQL Server Native Client 10.0):

      SELECT * FROM FXSpots; ID LHSCurrencyID RHSCurrencyID TenorID BBTicker WMRic C +orrespondingSpotID 6 1 1 1 foo bar 1 7 1 1 1 foo bar 1 8 1 1 1 foo bar 1 9 1 1 1 foo bar 1 10 1 1 1 foo bar 1 11 1 1 1 foo bar 1 12 1 1 1 foo bar 1
      #!c:/perl/bin/perl.exe use DBI; my $dbh = DBI->connect("dbi:ODBC:Market_Data_prod", "karl", "secret"); my ( $bbt, $wmr ); my $sql = 'select BBTicker, WMRic from FXSpots where id = 10'; # i can + get all.. my $sth = $dbh->prepare($sql); $sth->execute() || die "ERROR Unable to execute sql statment $sql...+" +; $sth->bind_columns( \$bbt, \$wmr ); $sth->fetch; # print ("BBticker = $bbt WMRic = "); # ...you missed $wmr print("BBticker = $bbt WMRic = $wmr"); __END__ C:\Dokumente und Einstellungen\karl\Desktop\market_data>market_data.pl BBticker = foo WMRic = bar

      Sorry that i could not help, Regards, Karl

        Yepp select 'foo' works like a charm. The failing table looks like this
        USE [Market_Data_prod] GO /****** Object: Table [dbo].[FXSpots] Script Date: 11/20/2012 19:4 +6:58 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[FXSpots]( [ID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL, [LHSCurrencyID] [int] NOT NULL, [RHSCurrencyID] [int] NOT NULL, [TenorID] [int] NOT NULL, [BBTicker] [nvarchar](50) NOT NULL, [WMRic] [nvarchar](50) NULL, [CorrespondingSpotID] [int] NULL, CONSTRAINT [PK_FXSpots] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY + = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 9 +0) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[FXSpots] WITH NOCHECK ADD CONSTRAINT [FK_FXSpots_ +Currencies] FOREIGN KEY([LHSCurrencyID]) REFERENCES [dbo].[Currencies] ([ID]) GO ALTER TABLE [dbo].[FXSpots] CHECK CONSTRAINT [FK_FXSpots_Currencies] GO ALTER TABLE [dbo].[FXSpots] WITH CHECK ADD CONSTRAINT [FK_FXSpots_Cu +rrencies1] FOREIGN KEY([RHSCurrencyID]) REFERENCES [dbo].[Currencies] ([ID]) GO ALTER TABLE [dbo].[FXSpots] CHECK CONSTRAINT [FK_FXSpots_Currencies1] GO
        and the working table looks like this:
        USE [Market_Data_prod] GO /****** Object: Table [dbo].[Indices] Script Date: 11/20/2012 19:4 +8:20 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[Indices]( [ID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL, [Description] [nvarchar](500) NOT NULL, [CurrencyID] [int] NOT NULL, [BBTicker] [nvarchar](50) NULL, [CRBTicker] [nvarchar](50) NULL, [ReutersRic] [nvarchar](50) NULL, [CloseTime] [datetime] NULL, CONSTRAINT [PK_EquityIndices] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY + = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 9 +0) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[Indices] WITH NOCHECK ADD CONSTRAINT [FK_EquityIn +dices_Currencies] FOREIGN KEY([CurrencyID]) REFERENCES [dbo].[Currencies] ([ID]) GO ALTER TABLE [dbo].[Indices] CHECK CONSTRAINT [FK_EquityIndices_Currenc +ies] GO
        thanks for the nice effort. However I think it's very strange that you get a result and I don't, hmm very annoying. Anyway thanks once again, I don't have the time to spend more time on this issue ritht now I will do some stuff manually and if I need to access more of that data I will look at it again. Cheers Pär
