Topic: Difference STGeomFromText from STPointFromText
Kind time of days!
At once I apologize for probably incorrect questions - I the beginner.
There are some methods creating an element geography (STGeomFromText, STPointFromText...).
As write on sites, method STPointFromText creates elements geography from the text on input:
SELECT @geo1 = geometry:: STGeomFromText (' POINT (3 4) ', 0).
1. Here a question, we like as transfer not the text, and object of type POINT or for what we then write "POINT ()"?
2. And why we then use STGeomFromText, instead of STPointFromText?
3. And here still write that STPointFromText creates an element geography Point from the text on input. An element geography Point, it that any subtype of type geography? Than they differ?
