odbc

问题 I'm trying to reader values from a System.Data.Odbc.OdbcDataReader. The problem with it is that it simply doesn't work. When I try to get a value from an existing column (field), it throws an exception. In my cae, FieldCount is 8 , but, for instance, a if I invoke reader.IsDBNull(4), it throws. For values column ids from 0 to 2, it retrieves the correct value. But reader[3] to reader[7], an exception is thrown with no information of what happened. Even worse, this code (GetName) also throws

问题 Couple of years using this site is as an invaluable resource, but first time posting.

问题 I have a problem where I need to search for a value in a ODBC which is a reserved word. So: SELECT * FROM Customer WHERE AccountNumber = 'Sum' In this case, 'Sum' is a reserved word and so I get a syntax error. In access the error is "The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect" Is there a way I can search for such a string? 回答1: Parameterise the string you wish to use as part of the WHERE clause and as I had

问题 I have put in the following code to sum up the values in POLIN.Qtyremn and OELIN.Otyord. It almost works, but instead of just summing the values, it is multiplying the quantities by four and adding them. I think this is being caused by the joins and it is calling the value four times and then adding them. SELECT POLIN.Itemkey, POLIN.Description, POLIN.Location, INLOC.Qtyonhand, Sum(POLIN.Qtyremn), Sum(OELIN.Qtyord) FROM X.dbo.INLOC INLOC, X.dbo.OELIN OELIN, X.dbo.POLIN POLIN WHERE INLOC

问题 I'm working on getting an ODBC connection in place but would like some assistance in making sure the setup is correct. I'm also hoping I can get some help in writing the PHP code to verify the connection to the DB is working. On a Windows Server 2008 R2 machine, I browse to C:\Windows\SysWOW64 and run odbcad32. (This is where I start getting confused...most pages I've looked at give pretty basic information for this.) The DB is a MS Access file. Which tab do I choose...User DSN...System DSN..

问题 I am using OdbcConnection class to connect to an external database. As a part of this process, I am also trying to handle the various exceptions thrown by this class (OdbcException). I find that the OdbcException contains a list called Errors which has multiple OdbcErrors. If I provide wrong credentials, I am able to get the access denied error but they are repeated twice in the errors list. The Errors list contains two errors but they are not unique. At the user end I see : ERROR [HY000]
