hello,

I'm having a problem in dynamically differentiating boolean fields from integer fields in Oracle.

Usually boolean fields are of type integer(1) in Oracle.
My question is : how can I retreive, using ODAC, the field size from the field type when it is integer(1) ?

Once I can get the size value of the integer type, I can easily differentiate between integer and boolean.

Thanks for your help.

You can use GetDataType, GetFieldScale and GetFieldPrecision methods of your DataSet object to retrieve such info.
For example:

Code: Select all

var
 i : integer;
 FieldName : string;
begin
with OraQuery1 do
  for i := 0 to FieldCount-1 do begin
    FieldName := Fields[i].FieldName;
    if (GetDataType(FieldName) = dtInteger) and (GetFieldScale(FieldName) = 0) and
       (GetFieldPrecision(FieldName) = 1) then
      ;//It's your boolean field
  end;
end;
