Hello,

How to read and write spatial data from/into the PostgreSQL or Oracle databases?
Is there something like asString for the geometry ?

Hello,

The GEOMETRY type is a PostgreSQL and Oracle server-specific types and it cannot be brought to UniDAC. Therefore in UniDAC you can work with such field types only as with strings. For example, to record data to a Point field, you can use the following code:

Code: Select all

  UniQuery1.FieldByName('f_point').AsString := '(2,3)';
