OPENROWSET and csv file

January 8, 2020, 6:43 pm

All,

The link shows how to create a format file using BCP. This assumes that the data is always extracted from a SQLServer table.

We receive lot of csv files from our business partners for which we cannot generate the format file and we plan to use them using OPENROWSET with the csv files being placed in Azure Blob Storage. Does anyone know how to generate the format file for a given csv file other than creating one manually?

In the below script, I manually created the format file currency.fmt for the csv data file currency.csv

Thanks,

rgn

 CREATE EXTERNAL DATA SOURCE pocBlobStorage
WITH (	TYPE = BLOB_STORAGE, 
		LOCATION = 'https://eventhubstore.blob.core.windows.net/datasets', 
		CREDENTIAL= sqlblob);

-- 2.4. Query remote file 
SELECT *
FROM OPENROWSET(BULK 'currency.csv',
				DATA_SOURCE = 'pocBlobStorage',
				FORMATFILE='currency.fmt',
				FIRSTROW=2,
				FORMATFILE_DATA_SOURCE = 'pocBlobStorage') as D
Inner Join [dbo].[State] C
On C.[id] = D.CurrencyKey

Agent job failing with string or binary data truncated, proc runs successful from SSMS

have a monthly sql agent job that executes a stored proc and it started failing a month ago with string or binary data would be truncated error. It has been running for years with no issues, no server changes or db changes related to this process for years. I restore the database and log files to a dev machine to get back to the point in time when the failure happens and the proc runs successful from SSMS. I have dealt with these errors in the past by putting a timestamp on the table being updated to locate the row, but since the proc runs I can't seem to find what is wrong. Is it something in the agent job itself possibly? I set the agent job up on the dev machine and it runs successfully. The proc is not complex, it is doing some value calculations, I don't see anywhere a string length could exceed any of the variables. 

Any ideas would be appreciated

Problem with XML parser memory leak

December 24, 2019, 1:02 am
$

We're using xml parameters to send a collection of data to stored procedure.
Typical (little simplified) use case would look like:

DECLARE @Values varchar(max) = '<Root><S>1</S><S>2</S><S>3</S></Root>', @h int
DECLARE @Val TABLE(ID smallint)

EXEC    sp_xml_preparedocument @h OUTPUT, @Values
INSERT INTO @Val(ID)
SELECT DISTINCT ID FROM OpenXML(@h,'Root/S',8)  WITH (ID smallint 'text()')
EXEC sp_xml_removedocument @h

SELECT * FROM @Val

We know we have to properly "pair" sp_xml_preparedocument /sp_xml_removedocument to avoid memory leaks.
Normally, our server works for months without any problems.

(I have to use external image because your portal is giving me "Body text cannot contain images or links until we are able to verify your account." error message)    https://imgpile.com/i/I5kAUR

At some point in time we're able to observe a constant growth of xml parser memory usage.
Our system still works, but it appears as if no document is being properly "removed", so our memory
usage graph begins to steadily grow.

(I have to use external image because your portal is giving me "Body text cannot contain images or links until we are able to verify your account." error message)    https://imgpile.com/i/I5kLYg

In the graph above 1.5K represents 1500MB. The only way to stop this endless growth is to restart
SQL Server service. After that it starts working just fine.

Is there a way to reclaim back all memory (some kind of overall xml parser memory "reset") without
rebooting the whole service?
Since our stored procedures are running pretty quickly (few seconds max.) is there a way to reclaim
all memory allocated by sp_xml_preparedocument which execution moment is older then some predefined time
(that would simply deallocate all "old" memory used by "old" xml documents)?

Any help would be very useful.

We're using version: Microsoft SQL Server 2014 (SP3-CU4) (KB4500181) - 12.0.6329.1 (X64)   Jul 20 2019 21:42:29   Copyright (c) Microsoft Corporation Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200: )

We also had identical problem with SQL Server 2012.

Indexes are not used

We have massive performance issues with a SQL Server. The system is fast in the morning and will be slow in the afternoon.
It could be determined that indexes over several tables are no longer used from a certain point in time and therefore table / index scans were executed, which burden the whole system.
The statistics are up-to-date, index fragmentation is low (-1%).
Only after all indexes are recreated will the better execution plan be selected again.
That happened yesterday and the day before yesterday.
The problem is expected to re-appear today.
A SQL Server 13.0.4001.0 is used.

Restore from SQL managed instance

January 10, 2020, 3:50 am

Hi all,

With the recent updates to SQL server 2019 versions we have encountered an issue with the version compatibility to Azure managed instance SQL versions.

I am getting this error message when trying to restore a backup file created from a DB on the managed instance - 

database was backed up on a server running version 15.00.2000. That version is incompatible with this server, which is running version 15.00.4003. Either restore the database on a server that supports the backup, or use a backup that is compatible with this server.

On the local server i have the latest CU1 installed and still it is not working although the version is higher.

The DBs are from an older instance so mostly compatibility level 110 (SQL server 2012).

Unfortunately the Data-tier export is also failing due to different reasons so i cant use that approach until fixing those.

Any idea on how to complete a restore with the new versions?

Before Azure went to version 15.00.2000 the normal restore process on the SSMS went without any issues when restoring the bak file.

Any help would be appreciated.

Thanks in advance

SQL database VSS differential backup API returns huge partial range when no data changed

January 27, 2017, 12:43 pm

I am calling VSS APIs to do a differential backup on a database (mdf file is ~16GB, log is ~15GB), which runs on SQL server 2014 sp 1. The partial range returned by IVssComponent::GetPartialFile() shows ~5GB data change in total, but I did not do any modification operations (insert, delete, etc) on the db after a full backup (which happened ~10min before). The native differential backup shows only ~2MB data backed up. The db has no index.

The partial ranges are small when the db file is small (< 8GB), that makes sense. For a large db, how the differential range is so big?

SQL Server 2017 CU18 Python Update Failure

We keep receiving the error of "Unable to connect to remote server" when trying to run the Python portion of the CU18 update for SQL Server 2017.  I've copied all CAB files over to the server, and specify the directory they are in each time the update is run.

This server is offline and my team does not want to open this up to the internet.  Has anyone else experienced the issue with this update and found a work around without simply opening it up to the internet?

I'm retrieving the CAB files from this link:  https://docs.microsoft.com/en-us/sql/advanced-analytics/install/sql-ml-cab-downloads?view=sql-server-2017  It does not have any CAB files for CU 17 or 18 yet, so I'm using what is listed for CU16.

We are on RSetup.exe version: 9.2.0.58.  

Here's a short section of the log in RSetup from one of my attempts.  I've specified the file location before this run, and previously, I'd tried simply copying the files to this location, but that still failed with the same "Unable to connect to the remote server" error.
