How to resolve the issue of SQL Server not allowing to save changes?

There could be several reasons why SQL Server does not allow changes to be saved:

1. Insufficient permissions: You may not have enough authority to make changes. Please ensure you have the necessary permissions to perform the desired actions.
2. Table is locked: If other users or processes are currently using the table, it may be locked and not available for changes. Please ensure there are no other users accessing or modifying the table.
3. Issue with transactions: If changes are made within a transaction and the transaction is not properly committed or rolled back, it may result in the changes not being saved. Please make sure to use transactions correctly and properly commit or rollback them.

One possible way to solve these issues could be:

1. Check permissions: Connect to SQL Server using login credentials with sufficient permissions, or contact the system administrator to obtain the necessary permissions.
2. Check for locks: Use the sys.dm_tran_locks view or the sp_who2 stored procedure to see if there are any other sessions locking the table. If there are locks, you can either wait for them to be released or contact a user with sufficient permissions to resolve the locking issue.
3. Check transactions: Ensure proper use of transactions by using BEGIN TRANSACTION, COMMIT, or ROLLBACK statements. If there are any transactions that have not been committed or rolled back, use the COMMIT or ROLLBACK statements to complete or rollback the transaction.

If the above methods still do not solve the problem, please provide more detailed information so that we can better assist you in resolving the issue.
