Hi All. I'm using Firedac to connect my VCL Application with SQLServer. Since some weeks, I have strange Lock on tables. I have a FDQuery whit a simple "Select * from MyTable". I show the result with a DBGrid (a simple DBGrid). Another User opens a form with a FDQuery: "Select * from MyTable where ID = 1". The FDQuery is in Cached Update. When the user POST the data, the application of the user that has the first form whit the DBGrid, freeze. And also the user that has posted the data will be freezed. An important think is that the table on DB has 2 triggers that fire when the table has changed and that makes computation on field of the table. I have created a T-SQL function that gives to me information about lock: the dataset that are opened for that table are in the list. There is something that I need to do to prevent this error? Thanks, Flavio
I am using Delphi 10.2 and I have been given a database to connect to and I have no control over its name. It is in the format xxxx.yyyy and when I create the connection definition, all is good and I can connect. I am specifying the database as xxxx.yyyy and setting the other various parameters appropriately (the same as I do for other databases). I can use the SQL tool in the connection editor to query the tables just fine. I create a simple TFDQuery consisting of a basic "select * from table" and when I attempt to run it, I am told that database xxxx is not in the list of valid servers and it should be added to sys.servers using sp_addlinkedserver. Clearly, what Firedac is passing to SQL server leads SQL server to interpret the xxxx as a server name. I have tried "select * from tablename", "select * from dbo.tablename", "select * from [xxxx.yyyy].tablename", "select * from [xxxx.yyyy].dbo.tablename" and other variations and still it refuses to work. I am setting no specific values for the components - I create the definition in the data explorer, test that it connects, test that I can use the "SQL script" tab to run various SQL statements. I then drag one of the tables onto the form designer (a quick test) and try to run the query and it fails with the message: "Could not find server 'xxxx' in sys.servers. Verify that the correct server name was specified. If necessary, execute the stored procedure sp_addlinked server to add the server to sys.servers". I have tried removing the database name from the connection definition, in the hope that the default database has been set - this does not work. Any suggestions, please? I am unable to request that the database name be changed.
