...gridview database update with datetime field not working
For some reason when the updatecommand runs my two datetime fields aren't entered into the database (a NULL value is). I can't figure out why.I think the problem is from the StartDate and EndDate, though no error is thrown, so it's hard to debug. The EventName and EventLocation get's updated properly, but the StartDate and EndDate get set to NULL Here is my SP:ALTER PROCEDURE dbo.spAdminInEvents @EventName varchar(200), @EventLocation varchar(250), @StartDate datetime, @EndDate datetimeA...TClientDataset and Calculated field problem (Delphi XE3)

I recently bought Delphi 2010 having moved from Lazarus/FPC, I used lazarus with Zeoslib package to use single file Sqlite databases in my apps and it worked great.
Having bought Delphi 2010 PRO the current Zeoslib does not support delphi 2010, so I am looking to embed a database in my apps that does not require any additional files installing on the end users computer except maybe a dll file with the executable.
My question is does delphi ship with anything similar to what I have described above, or can anyone recommend a freeware component that will function with Delphi 2010.
