Why does an almost 8 year old driver function while theĮxamining and altering potentially dozens (or hundreds) of queries and procedure result sets to convert any "varchar/nvarchar(max)" to "xxx(8000)" is not a pretty alternative.When using the "SQL Server" ODBC driver values queried from NVARCHAR(max) columns are returned correctly. The new-and-hotness ODBC Driver 13 for SQL Server (2015.131.4413.46 dated ) does not. The old-and-busted SQL Server driver (.17514 dated 2) worked perfectly. The results are: SQL Error: String data, right truncationĬhange the definition from varchar(max) to col_value varchar(8000) and the output is $DB->Sql($sql) & &Abend($DB,"exec ODBCTest") Select rnum, col_value from a Perl program roughly like this use Win32::ODBC If I have a stored procedure like so CREATE procedure as Lots of existing Perl executables (don't laugh - it works) that use ODBC to access our database.

We're in the process of upgrading to the newer drivers because we require TLS 1.2 support. The OP is referencing "ODBC Driver 13 for SQL Server" and the article only talks about "SQL Server Native Client". Unless I'm missing something obvious (always possible), that link does not talk about the ODBC driver in question.

What say you internet - any ideas on how to resolve this? Some might also suggest using OLE or some other data access mechanism in C# which doesn't really work either since we're seeing this in our unmananged C++codebase and I was just able to easily duplicate the behaviour in C#. Schema isn't an appealing alternative either. Staying with the older driver isn't an option as we're trying to move away from that driver since it does not support TLS 1.2. Obvious answers are to stay with the "SQL Server" driver and change the column to a non (max) type. I am only seeing this issue with drivers other than the ancient "SQL Server" driver. If I change the select statement to cast sValue as NVARCHAR(8000) everything works fine. When inside the sName block the field.name and field.value are correct. When inside the sValue block the field.name is correct, field.value in my case usually contains "\0\0\0\0–\0\0\0_GLOBAL" Rs.Open("SELECT, FROM WHERE = '_GLOBAL_:SerialNumber'", conn, CursorTypeEnum.adOpenStatic, LockTypeEnum.adLockReadOnly, 0) 0 (X64)ĪDODB.Recordset rs = new ADODB.Recordset()

Here is the kicker though - the garbage string that is returned is the correct length for what should have been returned.Ĭ# Code (Referencing Interop.ADODB - Microsoft ActiveX Data Objects 2.8 Library) ADODB.Connection conn = new ADODB.Connection() Ĭonn.Open("DSN=MyDatabaseDsn") // using "ODBC Driver 11 for SQL Server" (Also tried the V13 driver) pointing to an Microsoft SQL Server 2014 (SP1-CU13) (KB4019099). When querying values from this table the value for the sValue column will either be blank or contain what appears to be an uninitialized memory buffer. The table contains a row with a name of '_GLOBAL_:SerialNumber' and a value of '123456789012345' IDENTITY(1,1) NOT NULL,  (150) NOT NULL,  (max) NOT NULL We have a database with a table that has a structure as follows

I've tried this on two different Windows 10 Systems so I'm pretty sure it's not an environmental issue. When using "ODBC Driver 11 for SQL Server" (Also tried the V13 driver) I get garbage chars or what appears to be uninitialized When using the "SQL Server" ODBC driver values queried from NVARCHAR(max) columns are returned correctly.
