Where can I find prepared SQL statements (sp_prepare) in the system tables/views?

September 26, 2018, 10:31 am
$
0
0

Environment: SQL Server 2014 on Windows Server 2012 R2.

Our application uses hibernate and the jTDS JDBC driver, so we are (by default) getting generated SQL statements coming through as sp_prepare and sp_execute.  Sometimes, I am able to find the prepared queries in the cache, but sometimes I'm not.  By cache, I mean sys.dm_exec_query_stats and sys._dm_exec_cached_plans.  What's strange is that even if they seem to be gone from the cache, the prepared statements execute successfully.  I'm wondering if there is some other location where I could consistently see/find the prepared statements, hopefully by their integer handle?

Thank you,

-Peter

I set up an extended events session collecting the blocked process report.

Unfortunately I found that the <inputbuf> element in the XML report is truncated in the blocked/blocking process elements.

Is there a way to circumvent this truncation?

Thanks in advance

SQL Server 2016: Alter in-memory table throwing error during parallel execution

September 27, 2018, 7:50 am

Hello,

We ran into a weird issue with the SQL Server 2016 environment, our Application Upgrade is failing, that was handling the "Alter Table" to add a new column, for one of the in-memory tables.

In our SQL Server Instance, we have ~10 same application databases. When we run the upgrade sequentially one after another, it succeeds without any issues. 

But we are getting the below error when we try to upgrade all the DB's in parallel (to save time). Historically we haven't had any issues with the parallel upgrades (of course there's no parameter of In-Memory tables then).

"A user transaction that accesses memory optimized tables or natively compiled modules cannot access more than one user database or databases model and msdb, and it cannot write to master"

This is kind of a blocker for us, and any help in steps to resolve this, would help.

Thanks a lot.

Regds,

Kumar

Thanks, Kumar

Installing Visual Studio 2010 and SQL Server 2012 on Win7 X64 machine

Hello There, I am troubled installing SQL Server 2012 and Visual Studio 2010 on my development PC. 

If I install the SQL Server first and then the Visual Studio, it installs, but neither the Visual Studio nor the SQL Server Management Studio runs, claiming: Not all components of VS2010 are upgraded to SP1, and it provides a link where to download it.

When I browse to the link, it says that the address is not working now. It is permanently moved.

When I try to install SP1 from VS10SP1-KB2736182, it fails saying "Installation is blocked due to issues on your computer ... ". 

When I try to install SP1 from VS10SP1-KB983509 which I get from the SQL Server installation media, it starts and fails (rolls back)

If I install visual studio first, and then try to install SQL Server,  it say that Prior Visual Studio installation requires updates and the installation wizard doesn't progress anymore.

In the mean time, re-installed windows and then installed VS first, then applied VS10SP1-KB2736182, and then VS10SP1-KB983509. SQL Server 2012 installation wizard still claims that I need to apply updates to VS2010.

Are these two softwares not compatible with each other?

What is really happening?

Please Help, Help

Can you execute an extend stored proc from 64 bit sql 2008 r2 to access 32 bit windows 2000 machine

I realize all this is all bad, all legacy stuff which is the current production landscape I am trying to eliminate one step at a time. To get to more current hardware we are moving from a SQL 2000 machine to a SQL 2008 R2 machine and we have an issue with an extend proc not seeming to work. The proc was upgraded from a 32 bit dll to a 64 bit dll written in c++. The code does a number of things on the windows 2000 client which is 32 bit using windows sockets. My question is it regarding the 64 bit to 32 bit, since the call is from a 64 bit machine is this even possible? I am not the developer here and have no experience with using windows sockets which is what this DLL is doing.

handle text qualifier in bulk import xml format file

September 24, 2018, 2:25 pm

I have a csv file that I need to bulk import using an xml format file . I cannot use SSIS since I will have hundreds of csv files all different and already have the table metadata . I figured should be simpler to script format files based on the table schema ex:

Csv file is

"column 1","column 2","column 3","column 4","column 5","column 6"

"John","Doe","fieldJohn","valJohn","2.45","1"

"Mary","Jay","fieldMary","valMary","2.45","1"

"Roger","Moore","fieldRoger","valRoger","2.45","1"

Can generate an xml format file from table running bcp however this will not handle the “ for the text qualifiers before and after every column value but just the comma, how do I add the “ text qualifier before and after in the xml format file? even worse the import is incorrect if there are commas inside the column value . I cannot change the source export.

Thank you,

Hi I am on challenging work migrating Oracle 11 database to SQL Server 2016. This is One:one. Exactly same tables,views,etc should be in SQL Server.  I am explore how best I should do.  source database has following object types.  I have following analysis on Oracle

index 2010

tabes 2101

Views 334

LOB  100

Store procedures 200

Functions 201

Data base size is 600GB, I found some of the tables have over million records.

Task to do:

1. Any migration tool  recommend any.

2. Does it able to migrate BLOB data type data?

3. Its not practical to create tables with relative data types on SQL Server side. Tool would be best .Any suggestions .

4. Any method on system cut over, apply  change data to reduce down time of the system .

I am not sure SSMA(Migration Assistant ) is capable to handle large DBs and migrating BLOB, special   objects as well

Many thanks for golden advise

I am  configuring auto fresh process on SQL server 2016 from production to test env. users, permission are different to prod and test.

What I need to do before refresh backup the existing test env. users accounts, permissions and re-run permissions back to newly refresh DBs.

I found a note from google and looks similar to my requirement and save permmsions on master DB. Its a great one. but , grants fail when its exist or something wrong with the script.

How do you calculate free space that will be needed for a large table and where must the space exist?

Choices of reindex are:

Alter index all on TblName1 rebuild with (fillfactor = 95, online=on)    so not using Tempdb to sort.

Or


Table information from sp_spaceused:

namerows            reserved data          index_sizeunused
tblname1   1076099840 757502152 KB566286752 KB172174904 KB     19040496 KB

I am getting a strange problem at SQL instance (Version Microsoft SQL Server 2008 R2 (SP3-GDR) (KB4057113)). Server restart unexpectedly with following error:

Error: 3316, Severity: 21, State: 2. During undo of a logged operation in database 'tempdb', an error occurred at log record ID (14236:17637:199). The row was not found. Restore the database from a full backup, or repair the database.

 Error: 3314, Severity: 21, State: 4. During undoing of a logged operation in database 'tempdb', an error occurred at log record ID (14236:17637:199). Typically, the specific failure is logged previously as an error in the Windows Event Log service. Restore the database or file from a backup, or repair the database.

 Error: 3449, Severity: 21, State: 1.SQL Server must shut down in order to recover a database (database ID 2). The database is either a user database that could not be shut down or a system database. Restart SQL Server. If the database fails to recover after another startup, repair or restore the database.

After restart it runs for some time (few minutes or hours) and again restart with same error. There are no errors when DBCC CHECKDB is run on system databases.

Changing location of tempdb files and and recreating it in new location also doesn't work.

Am I missing something? Please suggest.

Hello, we had a application performance issue few days ago. The SQL version is 2008R2 with latest service pack. We are trying to get the root cause of the issue, but unable to get the root cause. The SQL Server error logs or the windows logs didn't capture much, so wondering where else we can look for the root cause. Any pointers would be helpful. Thanks.
