TSdfDataSet is a database component that implements text-based TDataSet in SDF format.
Schema
Record structure is derived from:
- Schema property if assigned. Schema is TStringList so you can use for example:
SDFDataSet1.Schema.CommaText := '"Field1=10","Field2=500"'; or SDFDataSet1.Schema.Append('<Field>=<Size>');
Where <Field> is FieldName and <Size> is size of TStringField which will be created
- First line of text file if property FirstLineAsSchema is set to true
