    Delphi 10.4, FireDac, StartTransaction causes ODBC error.

    I did suspect that, i.e. a transaction left open on Form1 causing a problem on Form2. Turned out to not be the case. Like Michael said, there was a stored procedure returning a result set but was executed with ExecProc.

    Michael, You are exactly right. I went back through all the stored procedures and found one which returns a result set. It's not used, but it is present. Thank you for the tip! 👍

    Delphi 10.4, FireDac, StartTransaction causes ODBC error.

    That's a good thing to check, but it isn't the case here. The only code executed before the StartTransaction is the non-database releated. I did find the situation causing the error, but I don't know why. I have one form open to a record. I open another form, a different form, and open it to the same record in same table. When StartTransaction fires, there's an error. When I close Form1, StartTransaction fires no error. My first suspension was an event alerter on Form1 causing an issue, but Form2 has not performed any CRUD yet when the error is raised. Also, execution never hits the event alerter's event when Form2 performs its action. As a workaround, I'll probably shove all the Delphi logic into a stored procedure & avoid StartTransaction.

  5. Here is a user experience answer to your technical question. Why pull in a few thousand records into a grid? "The user is looking for a record." If the user is finding a needle in a haystack, why make the haystack so large? Provide a search facility to narrow down the results. No user is going to read thousands of records in a single pull. On the technical question, narrow down if it's the grid or dataset. Disconnect the grid. Perform navigations in code, i.e. First, Last, Next, etc. Time it using TStopWatch. Reasonable speed? How does the speed change using a local vs TCP/IP connection? Verify setup using this info... https://docwiki.embarcadero.com/RADStudio/Sydney/en/Connect_to_Firebird_(FireDAC)

    Remote Debugging w/FireDAC & SQL Server

    Good info. Nice to know the facility exists. It would not have helped here. If the connection timeout is 30 seconds & failing, retrying at the same value would results in continuous failures. The fix is to allow more connection time in a remote debug environment. I've never needed retries before as connections are always stable where I've worked. Outside remote debugging, the client machine connects to the server in less than a second in this case.

    Remote Debugging w/FireDAC & SQL Server

    The 2nd link seemed helpful. There's no retry for FireDAC I know, but I did increase the LoginTImeout to 300 seconds. I didn't think it would be a problem since I'm connected via broadband, but I guess connecting was just outside the default 30 second timeout. Thanks.
  11. Remote debugging is working fine except for when the app tries to connect to the database server. When trying to open the TFDConnection, the following error occurs: First chance exception at $75F125F2. Exception class EMSSQLNativeException with message '[FireDAC][Phys][ODBC][Microsoft][SQL Server Native Client 11.0]Unable to complete login process due to delay in opening server connection'. The app connects without an issue when run on the remote machine from the scratch directory. Are there special preparations I need to take to enable remote debugging with FireDAC & SQL Server?

    ERD tool needed!

    Context Database Designer. https://www.contextsoft.com/products/designer/index.php Affordable. However, not upgraded since 2018. Not sure that matters. Idera's Aqua Data Studio has a modeler along with DB admin and DB development. Comes with Delphi Architect or as standalone. https://www.aquafold.com/aquadatastudio Tried DbSchema. It's okay & cheap but wouldn't recommend. DataGrip has some modeling abilities. Achilles heal is performance with large databases, like Great Plain Dynamics database.

    Remote desktop friendly

    I was working with a project over RDP using 10.4.1. My usual session was to connect, do work, and disconnect (not logoff). When I reconnected in a subsequent session, the IDE would very slowly redraw itself onto the screen. It's much better with 10.4.2 from start and while working.
  14. I saw this opportunity pop up. They're located in Abilene, Texas U.S. and write software for the oil & gas industry. The ad says open to remote work. I'd guess U.S. only. https://www.indeed.com/viewjob?jk=dd95941bac348323
  15. Using Delphi 10.4.1 w/connection transaction level set to dirty read. When I execute a stored procedure, which also executes set trans iso level to uncommitted, the stored procedure doesn't see an update performed in the app. Here is the outline of events -- FDCon.StartTrans FDDataSet.FieldX.AsInteger := 12 FDDataSet.Post FDStoredProc.Exec ... Here the stored proc selects FieldX and see it as null, not 12. Why? FDCon.Commit I want the stored procedure to see the uncommitted values posted by the app. EDIT: Cancel request. Turns out to be a stored procedure bug.
