Difference between SDO_CONTAINS and SDO_RELATE with MASK=CONTAINS?

What is the difference between following oracle spatial query? Does both function return same result? I am confused with MASK=CONTAINS

SDO_CONTAINS (col1_geometry,col2_geometry )='TRUE'
SDO_RELATE (col1_geometry,col2_geometry ,'MASK=CONTAINS')='TRUE'
Solution

  • They are exactly the same. SDO_CONTAINS is just simpler to write.
