Hi to all ,
first of all i'm really sorry because of my awful English .

When I export dataset to a report, on the Links tab of the Database Expert, the tables are automatically linked on several fields. i want to display just 2 field from different type of tables I give a error , and when i clear the links the error remove. I'm trying to figure out but I can not ,I check all of links and everything is OK ,I did it in version 8 and it was worked perfectly .
Any help would be greatly appreciated.

please help me .

Thank you.

The links between tables have to have the same data type.  The only way I have heard to get around this (depending on your database) is to create a command and do a data conversion on one of the fields for the link (i.e., INNER JOIN sometable on CAST(somefield as INT) = anotherfield).  I have never tried this (never needed to).
