Hi,
I have taken a backup of Database A from Server A1 then I restored this Database with name B on Server B1, now the application is working fine with Database A on Server A1 but not working with Database B on Server B1, I have checked the users, I have the users and I have given access to the users when it didn't work I have dropped the User which is connecting from Web application and recreated that user and granted the same permissions it had previously on this Database but still I am not able to use the application.
Here is the error that I am getting:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Any help would be greatly helpful thanks in advance.
Thanks,
Abdul Aleem

It's nothing to do with the database - your code can't connect to SQL Server.
- Check the name and instance name in your connection string.
- Check that SQL Server on server B1 is configured to allow remote connections.
- If you're using the Express version, check that the SQL Browser service is running on server B1.
- Using the SQL Server Configuration Manager on server B1, check under "SQL Server Network Configuration" that there is at least one enabled protocol;
- Using the SQL Server Configuration Manager on the client, check under "SQL Native Client Configuration" (both 64- and 32-bit) that at least one of the server protocols from B1 is enabled;
- Check any firewalls between the client and the server;

Yeah that's true I messed up connection string, thanks my friend.

Hello All,
We have job set up on a newly built server, windows 2012, with sql server 2012.
We have a job set up to run everyday. The first day the job ran look 7 hours. Slowly, over one months time it has creeped up to 8 hours now.
We are puzzled as to why this steady increase in time. WE have confirmed with our network folks no other job/process is running on the viritual server at the same time.
Looked at the event viewer, nothing to report. Is there any other place i could view the logs to get a better insight?
thanks!

Perhaps, in SQL Server Logs?
|

Would the logs files be in the following location:
\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Log
|
|
|
|
|
It seems to be correct.
My Logs are in C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log
Alternatively you can see the log in SSMS under Object Explorer -> Management -> SQL Server Logs

What is the nature of this job? Does it create records ? Or read the data? How big is this database ? How are many disks are installed on the server? How are they being used by the database engine? Are the Operating System and database files on different disks?
On the database server from a command prompt type "perfmon" to bring up the Performance Monitoring Utility. You want to add a counter for Logical disk / Avg Disk Queue Length (All disks) Look at the graph while the job is running, if you see high activity on one disk and low activity on another disk, you may want to consider moving some DB files around.
Here are a couple of things to consider:
1) Count the number of rows in the tables involved. Check these values daily, weekly, monthly.
2) Identify the tables that are growing.
3) Are there indexes on these tables? Check the fragmentation of the indexes. Possible create new indexes or revise existing ones.
NOTE: Be careful when adding indexes, it may help your one job, but have a negative impact on the rest of the system.
With the limited information given, I'm giving you some basic areas to investigate. I'll be glad to help you.

Hi ,
I have A nvarchar value Like This =id1-1,2 ; id2-1,3 ; .......i want return the nvarchar value with replace of id1,id2 values(i have a table id,value)

Do you ask about using CAST or/and CONVERT?
Or what did you mean?

I ned to convert below DB2 query to SQL
SUBSTR(xmlserialize(xmlagg(xmltext(CONCAT( ', ',DEL.COVERAGE_CODE))) as VARCHAR(1024)), 3) as COVERAGE_CODE
I am not able to get equivalents of xml related things in SQL. Any help would be appreciated

For that specific query, there are various equivalent methods in SQL:

STUFF
(
(
SELECT ', ' + DEL2.COVERAGE_CODE
FROM YourTable As DEL2
WHERE DEL2.GroupingField = DEL.GroupingField
FOR XML PATH(''), TYPE
).value('.', 'varchar(max)'),
1, 2, ''
)
Or, if you're using SQL 2017, you can use the new STRING_AGG function:
STRING_AGG (Transact-SQL) | Microsoft Docs[^]
STRING_AGG(DEL.COVERAGE_CODE, ', ')

Just a random question since I already have a different solution but I had the following situation.
I have a table with a billion rows (actually probably about 1.1 billion.)
I was trying to span the table, read every row and do an analysis.
Certainly couldn't load the entire table. I was using a paged query (limit/count). Each page took about 90 minutes for the query itself. So not really something that was going to allow me to do much analysis.
Any other ideas on spanning it or speeding it up?
At one point I was even considering just dumping it and writing an app to do the analysis outside of the database. That was about the only other solution I had.
The database was MySQL (AWS Aurora actually).
The relevant parts of the table were as follows and the id has a primary key. (I didn't design the table.)
Table T
id char(22)
RefId1 char(22)
RefId2 char(22)
...
|
|
|
|
|
The obvious question is: What kind of analysis?

Since I needed to span the database not sure how that matters unless you would perhaps suggest random sampling.
But in this case I needed to validate that the ids in each row did in fact match my expectations of what they were pointing to.

I think that is critical, the design of your analysis is the driving factor and is going to be the one area you can gain the most benefit from optimization.

Ok.
Per the OP table looks like the following
Table T
id char(22)
RefId1 char(22)
RefId2 char(22)
I need to do the following
1. Verify that RefId1 and RefId2 are in a different table either in that order (1,2) or (2,1)
2. Report if neither or only one id is found.
3. Report if more than one match is found
4. If found report if a different column (not documented above) is same as in the second table.
The second table also has a billion rows.
Both tables have indexes on the id, and the two other columns documented above.

oh that is ugly - the 1,2 - 2,1 is going to cost you.
Can you do it in a couple of steps, inner join on the 2 layouts and eliminate them from the process, possibly even move the non matching records into another table for your reporting analysis (one assumes the majority have valid matching records).

Yep - not my design.
Mycroft Holmes wrote: Can you do it in a couple of steps, inner join on the 2 layouts and eliminate them from the process,
I suspect that join between the two tables will return on the order of a billion rows. Either because there are very few rows that are not matched or there are zero. I am only expecting the first because with legacy data orphans might occur.
Mycroft Holmes wrote: possibly even move the non matching records
I have to find them first. Once I find them I don't consider the analysis to be a problem. Actually for those that do not match I consider it likely they are orphans.

Split it into groups by taking the first 1 or 2 characters, process each set independently.
Getting desperate here as I'm running out of ideas.

Also an interesting idea.
For base 64 encoding that would give approximately 244000 per query(2 characters0 and, per the other comment, it should be fast enough to use that a page.
The only limitation there would be if the values were not uniformly distributed.
