Then, I will convert the MS Access front end to cross platform(windows, Mac, Google and Linux with compatibility with Android and IOS. I don't know what language to use for this front end. I am a self taught developer and I know that I am not the best or fastest and would have to learn the language. What language would you recommend and why?
SQL Server Express
On my Windows 10 PCs I have been using for many years a third party application (Veeam Agent for Microsoft Windows) that used to depend on Microsoft SQL Server Express. SQL Server Express was installed during Veeam Agent installation. The latest release of Veeam Agent does not use anymore SQL Express, so I could uninstall it if not used by other applications. Given that I have lots of applications on my PCs, how can I check that none uses SQL Express before uninstalling it? RegardsSQL Server Agent is not starting after in place upgrade of SQL server from 2012 to 2019
SQL Server Agent is not starting after in place upgrade of SQL server from 2012 to 2019 I have done in place upgrade of SQL server from SQL 2012 Standard Edition (64-bit) SP4 to Microsoft SQL Server 2019 (RTM) - 15.0.2000.5 (X 64) Sep 24 2019 13:48:23 Copyright (C) 2019 Microsoft Corporation Standard Edition (64-bit) on Windows Server 2019 Datacenter 10.0 <X 64> (Build 17763: ) (Hypervisor). But after upgradation, sql server agent is in stopped state. I have tried with Local system account also but still no luck. Error in windows event logs is SQLServerAgent could not be started (reason: SQLServerAgent cannot start because the msdb database is read-only). I have checked and confirm that msdb database is not in read only state. Can someone help me to resolve this issue.Executing SQL trigger doesn't work if triggering events are generated by Azure Data Factory
Good day everyone, I have an issue getting data from Azure Data Factory into SQL. My original solution of using power automate was stymied by the combination of a mysteriously slow Stored Procedure when running it from Power Automate vs SSMS and the hard coded 2 minute timeout in flows. So my next idea was to run the SP from a trigger whenever records are inserted into a staging table from data factory using Copy Data action. *The trigger works fine when adding records in SSMS *The Data Factory pipeline successfully inserts rows into the staging table *After successful inserts from DF, the trigger in SQL on that staging table does not fire. Is this a bug? How can I work around this? And finally, is there a better way that doesn't involve deploying more services/licenses? Edit: To clarify what I' masking about. Key scenario I am attempting is in bold above. However, I have just decided to run the SP from Data Factory and pay the fees to run it. I don't have any more time to waste trying to troubleshoot.
