how find minimum of list stored in cell? can udf, feels overkill. min function pyspark.sql.functions works on groups (that result of groupby). min_ = udf(lambda inarr: min(inarr), integertype()) mydataframewithmin = mydataframe.withcolumn('min_value', min_(f.col('position_list'))) if imported pyspark.sql.functions , python's min covered, can still access __builtins__ prefix, example: min_ = udf(lambda inarr: __builtins__.min(inarr), integertype())

here's situation. i'm non-dba user in oracle database. such, have ddl , dml privileges own schema, can create, drop, update, etc tables in own schema. so let's write script creates , updates tables in own schema (let's call schema user1). when day comes leave company , need pass script on replacement (let's user2), how do if script works user1? user2 have go through script , replace references of user1 user2? point being i'd script work regardless user runs without having tinker it. first, if it's production script creates tables application , manipulates it's data, shouldn't run own user, dedicated production user. regardless, if you're running script in own schema, doesn't need explicitly reference it. remove references schema, , objects created under user running it, meaning user can run own account (assuming has basic dml/ddl permissions script requires).

i have array of planes (non infinite planes => finite dimensions) in array: plane *plane = [[plane alloc] initwithanchor: (arplaneanchor *)anchor]; [self.planes setobject:plane forkey:anchor.identifier]; (plane object heritates scnnode , has arplaneanchor *anchor , scnplane *planegeometry properties) how find planes of array planes hit hittest @ point of screen ? thanks ! i use categorybitmask , set example 3 (=11b). set categorybitmask option in hit test 2 (=10b). way nodes second bit of categroy 1 returned.
