Hi, we discovered that queries on sys.dm_db_index_usage_stats are getting very slowly when the sql server is running for a longer time without restart. The execution time is up to 30 seconds for the following query: SELECT object_name(object_id) objectName, last_user_update FROM sys.dm_db_index_usage_stats WHERE database_id=db_id() We get the following query plan: The Actual Rows in LOGINDEXSTATS are about 2 million. We found 2 similiar cases by searching the internet: https://stackoverflow.com/questions/52165370/query-against-sys-tables-sys-dm-db-index-usage-stats-slow https://www.linkedin.com/pulse/sql-server-2014-object-dependencies-dmvdmf-slow-andrea-bruschetta We tested the workaround (UPDATE STATISTICS sys.*** WITH FULLSCAN;) without success. How can we increase performance without restarting the database? Regards Dominik36Views0likes0CommentsWhy is SQL Server only storing 4000 characters in an NVARCHAR(MAX) column?
Hi Guys, I'm trying to insert a string with 10,000 plain characters (just repeated 'A's) into a column defined as NVARCHAR(MAX) in SQL Server. But LEN(Content) always returns 4000, not 10,000. I’ve verified that the column is NVARCHAR(MAX) and used the N prefix for Unicode. Still, the data seems to be truncated. What could be causing this? Is there something I'm missing in how SQL Server handles large strings? Tried this: CREATE TABLE LargeTextExample ( Id INT PRIMARY KEY IDENTITY(1,1), Content NVARCHAR(MAX) ); DECLARE @LongText NVARCHAR(MAX); SET @LongText = REPLICATE(N'A', 10000); INSERT INTO LargeTextExample (Content) VALUES (@LongText); SELECT LEN(Content) AS CharacterCount FROM LargeTextExample; Thanks, TusharSolved105Views0likes2CommentsSSMS 21/22 Error Upload BACPAC file to Azure Storage

I have the following (unusual) task: I need my T-SQL procedure to somehow call a VBA script. The VBA should copy all content of a certain sheet of an input Excel file into a certain sheet of an output Excel file. The physical full path of the input Excel file is available only in the T-SQL procedure. Therefore, the procedure should somehow pass the file path into the VBA script. How can I do that?69Views0likes1Commentadding computed column to MS SQL
would like to check how to add a computed column with the following requirement Column value will be C-yyyyMMdd-0001 where date will be from the CreatedDate column in the same table. 0001 is an auto-incremental value based on when the record is inserted on the same day eg, the first record added on 23/08/2025, the computed column will be C-20250823-0001. As the table may already contain existing data, a SQL script may also be necessary to update this new column with the correct value.113Views0likes3CommentsSQL Server - SOS_SCHEDULER_YIELD and Unbalanced NUMA Node Usage
Hi everyone, we've faced an unusual behavior on our SQL Server and would like to understand the cause and how to manage it properly. Our DB Server is a physical server with 64 cores (128 logical CPUs) and 4 NUMA nodes. During a peak in application requests/session, we noticed a significant increase in SOS_SCHEDULER_YIELD waits, with an unusual distribution of CPU load: only 2 NUMA nodes were heavily saturated, while the others remained underutilized. Our main questions are: At what point does SQL Server assign the execution NUMA node to a session/process? During connection establishment? When the statement starts executing? If processor affinity is left at its default setting (not manually configured at the instance level), what metrics can we monitor to better understand and manage this behavior? Any insights or experiences with similar cases would be greatly appreciated. Thanks in advance!218Views1like3CommentsSQL Server Config Manager Error "MMC could not create the snap-in"
Hi, I have seen this error elsewhere online. I have gone to mmc to enable the snap in and I still have had no fix. My computer is running Windows Server 2022, SQL Server Express 2022, and SSMS. I have reinstalled, repaired, and all of the other tricks. Help!Solved4.1KViews0likes4CommentsTable
Hello everyone, I have a problem. Our products are dimension-dependent (width / height) and the prices are stored in a table [Costinformation]. The grid table is in the Pricetable column. Rows are separated with CRLF and the individual columns with Tab. Table [Costinformation] Mandant Code Text Category Pricetable 1 4711 Product Table 1 Window 1 4712 Product Table 2 Door Example Pricetable-Column W / H 100 200 300 400 100 10,00 20,00 30,00 40,00 200 20,00 30,00 40,00 50,00 300 30,00 40,00 50,00 60,00 400 40,00 50,00 60,00 70,00 Now it is so that there are always price adjustments. In 100% of cases, this is in percentage terms. This means that the prices in the grid table have to be extrapolated. I need a solution so that I no longer have to do this manually. Can it be done directly via an SQL statement? Example: Product Table 1 --> price + 5% Produkt Table 2 --> price + 3 % I hope it is understandable. My English is not so good. I can also provide an example table. Thank you very much for you help. Greetings from Germany CharlyStellaSolved347Views0likes10Comments
