data type conversion - How to convert an Oracle column value of datatype SDO_GEOMETRY to String which has ST_IsValid=false -


is there function or way convert sdo_geometry datatype string in oracle ?

get_wkt() doesn't work sdo_geometry not formed (st_isvalid=false).

the best way write own oracle function my_get_wkt(), use as

update my_table set my_col = my_get_wkt(params);

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
