Nanodbc now supports nvarchar max and varchar max. Leave a Reply Cancel reply Comment. Seems to me it's an abject breakage of the "S" in SQL. Mus 6, 22 22 gold badges 77 77 silver badges bronze badges. So, mzuba, how generically do we know that the underlying DBMS believes a field to be "large"?
The documentation does not indicate a fixed cutoff, so it is not only specific to SQL Server, but also perhaps instance-specific meaning what is "large" on one server may not be large on another.
I dont't know if we can find out which fields are 'large'. This is a workaround and not a solution. Either 'All' or an integer number. The default value is 'All'. It also supports the input of 'all', 'ALL' and etc.

For numeric data types, the fractional part of the number was truncated. For time, timestamp, and interval data types containing a time component, the fractional portion of the time was truncated.
The data value of a column in the result set cannot be converted to the C data type specified by the argument TargetType. DM The specified column was bound. DM The number of the specified column was less than or equal to the number of the highest bound column. The communication link between the driver and the data source to which the driver was connected failed before the function completed processing.
Returning the numeric value as numeric or string for the column would have caused the whole as opposed to fractional part of the number to be truncated. For more information, see Appendix D: Data Types. The character column in the result set was bound to a C date, time, or timestamp structure, and the value in the column was an invalid date, time, or timestamp, respectively.
Assigning from an exact numeric or interval SQL type to an interval C type caused a loss of significant digits in the leading field. When returning data to an interval C type, there was no representation of the value of the SQL type in the interval C type. A character column in the result set was returned to a character C buffer, and the column contained a character for which there was no representation in the character set of the buffer.
The C type was an exact or approximate numeric, a datetime, or an interval data type; the SQL type of the column was a character data type; and the value in the column was not a valid literal of the bound C type. The driver was unable to allocate memory required to support execution or completion of the function. The column name is correct and indeed a record with 'xyz' value exists. The record is getting fetched too! But I'm having this particular error while trying to retrieve a couple of fields with rs.
The order of columns in the table is same as the order in which I'm retrieving them. And I'm not facing any problem retrieving another field which has width of characters.
I'll be very grateful indeed if someone can help me out of this particular problem Cheers, mates! MsoNormal, li. MsoNormal, div. MsoPlainText, li. MsoPlainText, div. Would a scenario like 3 be possible locally? I've scoured a bit for details about the interactions between and bit databases and data components and the details still seem very sketchy, so any help is appreciated. If yes what is the syntax? Questioncan u create a compound primary key and if yes what is the syntax?
Please excuse me from asking basic questions? I have an ODBC 3. When anerror occurs, I'd like to be able to determine whether the error isserious enough that the database connection has been lost, so I canhave the application try to reconnect automatically.
My understandingis that any error of severity 20 or above includes a broken connection,but I'm having difficulty retrieving the error severity through ODBC. Also, as a test, I stopped the database while my application is stillrunning, and the first error I received had a native error code of There is no 55 error in the sysmessages table, so I'm confused as towhat the severity of the error is.
Can anyone shed some light on why Iwould be receiving an error code that is not in the sysmessages table,and where I might be able to find more information about the error? Thanks in advance,Abram. I have no idea what caused it? I did try to dbcc reindex but it failed reporting that can't create index because of duplicate in primary index key????
Please show me a way to fix this. Thanks Dave. And really I don't know what can I do to prevent such problems. I know how to fix it with a dbreindex, but it blocks the production during several minutes, and we have to restart the whole plant Hello experts.
Excuse my SQL newbie status. I didn't entirely know what I was doing so I was using Crystal Reports 11 as an "application layer" pulling against a stored procedure. Well I guess ODBC connections don't support temp table output from stored procedures, or at least I don't know how to do it. So I've rewritten my stored procedure so it inputs and outputs data using BCP, rather than just sending a simple select query.
My problem is that I cannot get CR to add the stored procedure back in to the report. How do I find it and close it? This is my crusial question. Less crucial but helpful: How do I write an SP so it can be called from a report program like CR and will return its result set to the application? What's a good, simple "application layer" I can use if I'm doing all the logic in native SQL stored procedures?
