BCD Overflow

Postby evandro.abreu » Mon 23 Mar 2015 13:51

Hello, is taking place the following error: BCD Overflow.
The error occurs when the following line:

vlTotal: = QATPR.fieldbyname.('vl_fixado').AsFloat;

EnableBCD is true.
Driver version 3.5.7
Delphi 7
PostgreSQL 9.1

How do I correct this problem?


P.S. Translation by Google Translator.

The 'BCD Overflow' error message can occur when the value retrieved from the database exceeds a limitation for the TBcd type in Delphi 7. For example, when the number of digits in such BCD value exceeds 32 (in PostgreSQL - numeric(33,1)). In such cases, the error is generated by Delphi - and we can't affect this behavior.

Please specify the data type you are using for the 'vl_fixado' field in PostgreSQL.
