        case1 <wenzhouwww>: [TD-11804]  test case for elapsed function :

        this test case is for aggregate function elapsed , elapsed function can only used for the timestamp primary key column (ts) ,
        it has two input parameters,  the first parameter is necessary, basic SQL as follow:

        ===================================================================================================================================
        SELECT ELAPSED(field_name[, time_unit]) FROM { tb_name | stb_name } [WHERE clause] [INTERVAL(interval [, offset]) [SLIDING sliding]];
        ===================================================================================================================================

        elapsed function can acting on ordinary tables and super tables , notice that this function is related to the timeline.
        If it acts on a super table , it must be group by tbname . by the way ,this function support nested query.

        The scenarios covered by the test cases are as follows:

        ====================================================================================================================================

        case: select * from table|stable[group by tbname]|regular_table

        case:select elapsed(ts) from table|stable where clause interval (units) [fill(LINEAR,NEXT,PREV,VALUE,NULL)] [group by tbname] order [by ts desc asc|desc];

        case:select elapsed(ts) , elapsed(ts,unit_time1)*regular_num1 , elapsed(ts,unit_time1)+regular_num2 from table|stable where clause interval (units) [fill(LINEAR,NEXT,PREV,VALUE,NULL)] [group by tbname] order [by ts desc asc|desc];

        //mixup with all functions only once query (it's different with nest query)
        case:select elapsed(ts), count(*), avg(col), twa(col), irate(col), sum(col), stddev(col), leastsquares(col, 1, 1),min(col), max(col), first(col), last(col), percentile(col, 20), apercentile(col, 30), last_row(col), spread(col)from table|stable where clause interval (units)  [fill(LINEAR,NEXT,PREV,VALUE,NULL)] [group by tbname] order [by ts desc asc|desc];

        //mixup with ordinary col
        case:select ts ,elapsed(ts)*10 ,col+5 from table|stable where clause interval (units) [fill(LINEAR,NEXT,PREV,VALUE,NULL)] [group by tbname] order [by ts desc asc|desc];

        //nest query
        case:select elapsed(ts) from (select elapsed(ts), count(*), avg(col), twa(col), irate(col), sum(col), stddev(col), leastsquares(col, 1, 1),min(col), max(col), first(col), last(col), percentile(col, 20), apercentile(col, 30), last_row(col), spread(col)from table|stable where clause interval (units)  [fill(LINEAR,NEXT,PREV,VALUE,NULL)] [group by tbname] order [by ts desc asc|desc]) where clause interval (units)  [fill(LINEAR,NEXT,PREV,VALUE,NULL)] [group by tbname] order [by ts desc asc|desc];

        //clause about filter condition
        case:select  elapsed(ts) from table|stable[group by tbname] where [ts|col|tag >|<|=|>=|<=|=|<>|!= value] | [between ... and ...] |[in] |[is null|not null] interval (unit_time) ;
        case:select  elapsed(ts) from table|stable[group by tbname] where clause1 and clause 2 and clause3  interval (unit_time)  ;

        //JOIN query
        case:select elapsed(ts) from TABLE1 as tb1 , TABLE2 as tb2 where join_condition [TABLE1 and TABLE2 can be stable|table|sub_table|empty_table]

        //UNION ALL query
       case:select elapsed(ts) from TABLE1 union all select elapsed(ts) from TABLE2 [TABLE1 and TABLE2 can be stable|table|sub_table|empty_table]

        // Window aggregation

        case:select elapsed(ts) from t1 where  clause session(ts, time_units) ;
        case:select elapsed(ts) from t1 where  clause state_window(regular_nums);

        // Continuous query
        case:create table select elapsed(ts)  ,avg(col) from (select elapsed(ts) ts_inter ,avg(col) col from stable|table interval (unit_time) [fill(LINEAR,NEXT,PREV,VALUE,NULL)][group by tbname])  interval (unit_time) [fill(LINEAR,NEXT,PREV,VALUE,NULL) sliding(unit_time_windows);
