explain differences between two different updates
To sum it up: The first approach (parameterized query/prepared statement) is best, because it is easy: automagical quoting and formatting of the parameters can be more efficient: the DBMS may optimize avoids fetching and storing the resultset (@Ansgar) scales better: would work for many records without change guards against SQL-Injection...
Glimpse ADO “ExecuteReaderAsync()” does not respond
c#,.net,async-await,ado,glimpse
This: var result = cmd.ExecuteReaderAsync().Result; Is causing your code to deadlock. I'm assuming you're running an app which passes around a synchronization context (UI, ASP.NET, Universal App or such). This is why you shouldn't block on async code To get around this, you'll have to make your method async Task...
Delphi ADO : Locate with dataset filter on bug
The problem with TCustomADODataSet.Locate is that it's internally using Recordset.Clone and trying to locate a record in the cloned recordset, without setting the filter to the cloned recordset (see ADODB TCustomADODataSet.LocateRecord). From the Remarks in the docs: The Filter property of the original Recordset, if any, will not be applied...

ExecSQL is only used for SQL statements that don't return a recordset, and to determine the results you use RowsAffected. For SELECT statements (which return a recordset), you use Open or set Active to true. Also, count is a reserved word in most SQL dialects (as in SELECT Count(*) FROM...
How to GROUP BY in groups of N rows?
SQL tables are inherently unordered, so I assume that you want to order by mydate descending. You can enumerate the rows using variables, use arithmetic to define the groups, and then get the average: select avg(age) from (select t.*, (@rn := @rn + 1) as seqnum from table t cross...
