Hi,

Just upgraded from SDAC v7.3.16 to v8.0.3. System Windows 10, Delphi 10 Seattle prof.
I've got 2 problems, the main problem is the result of a select in the ClientDataSet with v8.0.3. With v8.0.3 the result is totally different (v7.3.16 is correct) and is a mess. The only thing I've changed is the version of SDAC en recompiled the application. The query is the same. If I go back to v7.3.16 the result is correct. I can't solve this problem with Data Type Mapping, it looks like some results are shaken. What can cause the differences in the results (see below)?

The second problem is with a database field numeric(9,0) which is a persistent field in Delphi type TFloadField. A number like 90031403 with v8.0.3 is shown as 4,5036030633582E16 (see the field RELDOSNR below). So I've tried Data Type Mapping, but then I've to redefine the persistent field in the code which then becomes a TIntegerField. I can solve that but why is this different in v8.0.3 ?

N.B. I've tried v8.0.2 too and it seems that both problems do not exists with v7.3.16 and v8.0.2 so it looks the problem is only in v8.0.3.

Result 7.3.16 and 8.0.2:

In order for us to investigate the issue, please send us a small sample demonstrating the issue, as well as the scripts to create tables.

Today, after the release of v8.0.4, I de-installed v8.0.2 and tried v8.0.4. The results now are correct. After this, I installed v8.0.3 again and the problem I reported still exists. I went back to v8.0.4 and the problem I reported is solved. The only thing I've changed is just the version of SDAC and did a recompile to notice the differences.

This issue can be closed, but something was certainly wrong in v8.0.3.

Glad to see that the issue was resolved.
