 Hello,

1. look for the 'Local SQL Help' file in the Delphi/Help directory;

2. you can add records to a TQuery data set only if the TQuery.RequestLive property is True and your query statement meets some syntax requirements; in the Delphi Help look for 'TQuery', and follow for 'Requesting a live result set'.

HTH, julio

hi
10x 4 the answer but stile i have problem ...
you wrote "query statement meets some syntax requirements; in the Delphi Help look for 'TQuery', and follow for 'Requesting a live result set'"
i dont understand how to do it ,
to be more specific - i execute and Tquery , now i have a dataset that i want to add a record using (for example) the Tquery append command (not the sql append  command )
even if i set the RequestLive to True i recive a read only  Error message;
if u can deliver me an answer & example its would be great !
10x any way

Ok, would you mind posting here your query statement?
This could make me able to tell what exactely is the problem.

BTW, here are the syntax requirements:

--//--
Restrictions on live queries

Single table queries or views are updateable provided that:

There are no JOINs, UNIONs, INTERSECTs, or MINUS operations.
There is no DISTINCT key word in the SELECT.
There are no aggregate operations.
The table referenced in the FROM clause is either an updateable base table or an updateable view.
There is no GROUP BY or HAVING clause.
There are no subqueries.
Any ORDER BY clause can be satisfied with an index.
