Microsoft OLEDB Provider for SQL , DateTime2 is added as DateTime - sql-server

I am using SSL from now on so I moved from the integrated SQL OLEDB (MDAC) to the Microsoft OLE DB Driver for SQL Server.
And I was hoping that suddenly datetime2(7) would work. But unfortunately I only get datetime back, and the Nanoseconds are gone. Is this expected?
Example: 2022-03-11 07:39:53.86286
Delphi with MSOLEDBSQL19.1 2022-03-11 07:39:59 ( .86286 is not present )
I used FormatDateTime('dd.MM.yyyy hh:nn:ss.zzzzz',ADOQuery1Lastmodzeit.Value)
11.03.2022 07:39:53.862, but still wonder why the 86 is cut off.
So now at least I have something.
Even though ADOQUERY returns datetime2(5) as datetime. If I set the displayproperty of ADOQUERY Field to dd.mm.yyyy HH:nn:ss.zzzzz then I get the same 11.03.2022 07:39:53.862. Now I only wonder why is the rest cut off?

Best way to handle time formats from SQL Server in Access front end

I've migrated a database formerly in Access to SQL Server and am now rebuilding my Access front end to work with that SQL Server back end using a DSN-less link. I'm running into issues with new data entry in my time field. The error I get is ODBC--update on a linked table...failed. [Microsoft][ODBC Driver 17 for SQL Server]Invalid character value for cast specification (#0). I'm assuming this has to do with the way Access converts the data into short text from SQL Server, where it is a time(0) data type.
My question is what is the best way to handle "time" data to work in both Access and SQL Server? Ideally users would enter data in Access simply as something like "0130" where this means "1 hour and 30 minutes" (we never record seconds). And ideally the data in SQL Server would be formatted in some sort of time or datetime/datetime2 format.
I'm in a position to modify the formatting or code of the Access front end or the SQL Server back end (or both)--what's the cleanest way to go about this?
The best way is to user data type DateTime in SQL Server. Any ODBC driver will read and write that from Access as native DateTime of VBA.
If you must use DateTime2 in SQL Server, you must install and use one of the never ODBC drivers, not the "SQL Server" ODBC driver that comes with Windows as it cannot read the microsecond resolution of DateTime2.
You should never use the other date/time data types of SQL Server: Time and Short Date

On SSMS, ODBC linked server queries show unicode text data

In SSMS I'm connected to an Intersystems Cache database using ODBC driver and linked server When I fetch data using a SQL query like
SELECT Text FROM OPENQUERY([ODBC_CACHE_DB],'SELECT TOP 100 Text FROM cls.Actions')
IN SSMS it gives results but it gives ? for arabic characters like
"18:29:00 [Mohamad] ????? ??? ?? ??? ??? ?????? ????? ? 18:30:30 [Customer] Hi Sirius is jai"
how could get arabic texts ?
note: I can read and write arabic text with using nvarchar data type
Had a similar issue. My setup was a linked server setup between MSSQL 2012 cluster and Intersystems Cache 2009.x using MS OLE ODBC provider.
My observations below:
Convert/Cast on the column with nvarchar datatype did not work -- as in it shows the ???? (This is on SSMS)
When using 3rd Party DB management tools such as Database.net and WinSQL, I was able to see the correct characters.
Playing around with the ODBC driver's Unicode SQL Types function only intermittently helped show the correct characters.
The solution:
Enable Unicode SQL Types function on the ODBC driver
Make changes to the test sql query that is being executed on the Intersystems Cache db. If you keep executing the same query, the output is cached for sometime (not sure how long exactly).
In my case, the sql server cluster was not under my control and took a few days to play around with the different variations.

Unable to retrieve varchar(max) fields using VB6 ADO on SQL Server with ODBC 13 drivers

We have a VB6 application using ADO and needed to update the SQL Server ODBC drivers to handle TLS 1.2 compliancy. I am able to query a varchar(max) field using the original {SQL Server} driver, but any newer ODBC driver will not return varchar(max) fields (13, 11, SQL Native Client 11, 10, etc.). All the other fields field types return fine with newer drivers, except the varchar(max).
I am setting my database connection string as follows:
PROVIDER=MSDASQL;Driver={ODBC Driver 13 for SQL Server};Server=server;DATABASE=dbname;UID=user;PWD=password;DataTypeCompatibility=80;MARS Connection=True;
Then executing the ADO recordset using:
Set recordset1 = gsSQLConn.Execute(strSQL, recordsaffected, adCmdText)
The SQL is
SELECT TABLE.NOTES AS [Value] From TABLE WHERE (((TABLE.NOTES) Is Not Null) AND ((TABLE.TABLE_ID)=#####))
where ##### is a valid integer ID for the table.
The return value shows as:
2 à
and is type 200 (adVarChar).
I am at a loss on this one, and not sure why I cannot get the newer ODBC drivers to read the varchar(max) fields. I did look into the SQLGetData function, but not quite sure how to get it working for my scenario, or even if it's necessary.

SSIS - SQL Server datetimeoffset(0) destination column recognized as DT_WSTR

We get data delivered to us in a flat file. A date column we want to store in a destination column called DWValidFrom has the following format:
2017-02-06T22:07:09Z
In SSIS using a Flat File Connection Manager, I set the datatype of said column to DT_DBTIMESTAMPOFFSET. It correctly shows us when checking the data in the Columns and Preview pages of the Connection Manager.
In SQL Server, I created the destination table, and defined the DWValidFrom column as datetimeoffset(0):
[DWValidFrom] [datetimeoffset](0) NOT NULL,
When I attempt to set the mappings in the OLE DB Destination object, which has been set to the SQL Server table in question, SSIS won't have it, and throws the following error:
The OLE DB provider used by the OLE DB adapter cannot convert between types "DT_DBTIMESTAMPOFFSET" and "DT_WSTR" for "DWValidFrom".
Suspecting something off with my regional settings, I issued the following query in Management Studio to ensure the format of the date wouldn't change:
SELECT CAST('2017-02-06T22:07:09Z' AS datetimeoffset(0))
This yielded the following result:
2017-02-06 22:07:09 +00:00
Why is SSIS not recognizing the column's proper data type? I do not have any other conversions or expressions set, so I'm confused as to why SSIS won't allow me to push a valid datetimeoffset.
We're using SQL Server 2014, Visual Studio 2015.
Thanks.
This sounds like the OLEDB source metadata is out of sync with the changes you made on the flat file connection manager. The quickest fix it would be to recreate the OLEDB source, but don't do that quite yet.
SSIS is not going to like that standard ISO format for the date. If you remove the "T" in the middle and the "Z" at the end it be ok. i.e.
2017-02-06 22:07:09
Because of this conversion issue in SSIS, the connection manager will probably fail in converting the string to datetimeoffset. So you will need to configure it as a string and then fix it's value in a derived column:
(DT_DBTIMESTAMPOFFSET, 0) REPLACE(REPLACE( [DWValidFrom] , "T", " " ), "Z", "")
Hope that helps,

The issue seemed to be that the OLEDB destination does not recognize datetimeoffset as a valid column format. Despite everything working in SQL Server and SSIS pushing a datetime that would be perfectly valid, the OLEDB destination wouldn't have any of it.
I considered using a SQL Server destination, but because the target server is a different server than the one we develop on, that wasn't an option either.
The fix for us was to instead format the columns using datetime as a datatype, which causes us to loose the timezone info, but because all of the dates were UTC, we really don't miss any data.
Quick Answer: Set DataTypeCompatibility to 0
I noticed in Connection Manager for my SQL Server Native Client 11.0 (OLEDB) connection, clicking on "All", then under the SQLNCLI11.1 section there's a value DataTypeCompatibility which was set to "80". 80 is code for SQL Server 2000 compatibility, well before they introduced TimeStampOffset (or in my case DT_DBDATE and DT_DBTIME2 types). I tried setting compatibility to 130, then 100, but "Test Connection" failed.
At https://learn.microsoft.com/en-us/sql/relational-databases/native-client/applications/using-connection-string-keywords-with-sql-server-native-client?view=sql-server-2017 there's a table, specifying information about this value
DataTypeCompatibility SSPROP_INIT_DATATYPECOMPATIBILITY Specifies the mode of data type handling to use. Recognized values are "0" for provider data types and "80" for SQL Server 2000 data types.
Changing the value to 0, then refreshing all of my connections using the OLEDB connection manager seems to have done the trick - now all my database's types are recognized rather than forcing it to nvarchar/DT_WSTR

linked server problem at sql server while connecting to oracle dbms

I have created a linked-server definition according to the article at :
http://www.ideaexcursion.com/2009/01/05/connecting-to-oracle-from-sql-server/
My aim is to transfer rows to tables at Oracle 11gR2.
After creating linked server, whenever I try to select a table using a query like :
SELECT *
FROM [192.168.1.188]..[ESIPARIS].[T_ERROR_LOG]
I get the error below :
Msg 7356, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "192.168.1.188"
supplied inconsistent metadata for a column. The column "EVENT_OBJECT"
(compile-time ordinal 2) of object ""ESIPARIS"."T_ERROR_LOG"" was reported
to have a "LENGTH" of 50 at compile time and 100 at run time.
One more thing is that it duplicates field names whenever a select statment is prepared by "Sql Server Management Studio", some fields are duplicated as below :
SELECT [EVENT_DATE]
,[EVENT_DATE]
,[EVENT_DATE]
,[EVENT_DATE]
,[EVENT_OBJECT]
,[EVENT_OBJECT]
,[EVENT_OBJECT]
,[EVENT_OBJECT]
,[MESSAGE]
,[MESSAGE]
,[MESSAGE]
,[MESSAGE]
,[EVENT_ID]
FROM [192.168.1.188]..[ESIPARIS].[T_ERROR_LOG]
I would be very happy to hear from you about any ideas, thank you for your concern,

There are a number of scenarios which might throw this error:
your distributed query in SQL Server references a view with an underlying table in Oracle with a primary key column created in a certain way, Find out more
there's a bug when the querying a view with numeric columns. Find out more
it may be a problem with driver incompatibility, such as using the MS OleDB driver instead of the one Oracle provides.
If it isn't the driver one possible workaround is to use OPENQUERY. Otherwise. this support note contains general information on troubleshooting linked server and Oracle.
(This problem is a fairly generic one, so it turned out that the actual resolution was none of the things I suggested. I'm incorporating #kayhanyüksel's solution in the body of this response for the sake of completeness.)
Solved it with changes at listener and tnsnames. We are now able to connect from SQL Server to Oracle 11gR2 (running on 64 bit Red Hat Enterprise Linux 5.4 ) and vice versa. Documents followed are
- Making a Connection from Oracle to SQL Server
- The Oracle Gateways documentation
I had the same problem: The column ...... was reported
to have a "LENGTH" of 50 at compile time and 100 at run time. and duplicate column names when selected.
while i was trying to run a query in MS SQL from an ORACLE 11g database
I used the follownig type of query and it worked !
DECLARE #TSQL varchar(8000)
SELECT #TSQL = 'SELECT * FROM OPENQUERY(MyLinkedServer,''SELECT * FROM TableName'')'
EXEC (#TSQL)
where MyLinkedServer is the name of the linked server and
TableName is the name of the table.
here you have the link to the article that helped me: http://support.microsoft.com/kb/314520
Old thread but it may be useful to someone.
When I recently encountered this error, using as provider the MS OleDB driver instead of the Oracle OleDB provider solved the problem.
I have the same issue with 11g client but it was disappeared with client version 12 which works for me is using OPENQUERY and to_char with the field that makes problem.
I confirm that SQL management studio (no matter what version) gives many duplicated field. The only installing of last driver version we can have consistent queries. I hope it can be useful for you!
