DB change of account
Our database jobs, such as full database backups, transaction log backups, system database backups, Reorg job , Update stats and few DB related jobs and task scheduler jobs for housekeeping the trace files , are owned by one of our SQL DB account, which also has DB and SQL server admin privileges . Without disrupting the above-mentioned job schedules, we would like to remove the DB admin & SQL admin privileges for that account . I.e, let this account be used only schedule SQL agents job purpose . Could you please help me obtain information from support how to convert that account without impact of DB operations ?
SQL Server does not reduce the size of MDF and LDF
I am a SQL Server 2017 user, I deleted a table that had too many records, but after the delete process, the size of the MDF and LDF files did not decrease, but increased. I have shrunk the file but the file size remains the same. What should I do to change the file size?
Parameterize OLE DB Destination?
I have a large number of tables to backfill and I was hoping to automate this process with a package parameter instead of creating a dataflow for each table (see screenshot below). Package parameter like 'tbl_a, tbl_b, tbl_c' Followed by an Execute Script that splits this string into an Array. The array would then be enumated in a Foreach loop container. 3a. SQL command from enumerated variable would be fed into an OLE DB Source SQL Command 'Select * from tbl_a', 'Select * from tbl_b', etc. 3b. Table name or view name variable in OLE Destination would be given different table names 'tbl_a' , 'tbl_bl', tbl_c' through the enumerated variables Where it fails is when tbl_a, tbl_b is enumarated into OLE DB Destination Error: 0xC020201B at Data Flow Task, OLE DB Destination [2]: The number of input columns for OLE DB Destination.Inputs[OLE DB Destination Input] cannot be zero. Error: 0xC004706B at Data Flow Task, SSIS.Pipeline: "OLE DB Destination" failed validation and returned validation status "VS_ISBROKEN". Is there a way to parameterize OLE DB Destination? Is there a way to avoid need column mappings or somehow query all the columns from the OLE DB Source to feed into OLE DB Destination? Each table is different and mapping the columns for one backfill would completely blow up the next backfill in the batch. Is there another Task I can use in place of OLE DB Destination that can be preceded by OLE DB Source? Thanks in advance
SQL 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!

Current SQL Server Certifications
Hello, I had a couple Microsoft certifications many years ago and am interested in getting re-certified in SQL Server. I looked on learning.microsoft.com but couldn't find any certification options. Am I looking in the right place? Does Microsoft still offer SQL Server certifications? Thanks, Brett
