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 ?

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

update my_table set my_col = my_get_wkt(params);
