EDataMappingError Value is out of range: 0

Hi,
what does such exception mean?

It references a very normal TFloatField, without any constraints...

callstack:

Code: Select all

btw. i'm using such data type mapping setting

DataTypeMap.AddDBTypeRule(msReal, ftFloat);

and the field is a real field (defined in query like "(cast 0 as float(15))" )

Hello,

We can't reproduce the issue. The "select cast(0 as float(15)) as test" command is executed with no errors on the latest SDAC version 7.2.10. Please specify the SDAC version and the version of IDE and SQL Server.
