Как сделать динамический стержень в Oracle PL SQL

У меня есть ниже запрос: И я хочу, чтобы сделать эту ось динамика в процедурахКак сделать динамический стержень в Oracle PL SQL

Изменение прок как ниже

  BEGIN 
      -- Use another variable and initialize with count(*) from prev_month (say totalCount) 
      -- Initialize another counter say curCount = 0 
      -- 
      FOR x IN (select time_stamp from prev_month) 

      LOOP 
       -- increment curCount. If curCount = totalCount 
       -- then use 
       -- l_query := l_query|| REPLACE (' TO_DATE(''$X$'',''yyyymmdd'') as DAY_$X$_TOTAL ','$X$',x.time_stamp); --your code without comma at the end. 
       -- else 
       l_query := l_query|| REPLACE (' TO_DATE(''$X$'',''yyyymmdd'') as DAY_$X$_TOTAL, ','$X$',x.time_stamp); 
       -- end if. 
      END LOOP;

EDIT: Точный синтаксис

  BEGIN 
       curCount := 0; 
       SELECT COUNT (*) INTO o_count FROM prev_month; 
       FOR x IN (select time_stamp from prev_month) 

       LOOP 
        curCount := curCount +1; -- increment curCount. 
        IF curCount = o_count THEN 
         l_query :=l_query|| REPLACE (' TO_DATE(''$X$'',''yyyymmdd'') as DAY_$X$_TOTAL ','$X$',x.time_stamp); 
        else 
         l_query := l_query|| REPLACE (' TO_DATE(''$X$'',''yyyymmdd'') as DAY_$X$_TOTAL, ','$X$',x.time_stamp);

Привет @ Utsav, я пробовал ваши предложения, но все тот же результат: BEGIN curCount: = 0; SELECT COUNT (*) INTO o_count FROM prev_month; ДЛЯ х В (ВЫБРАТЬ ИЗ time_stamp prev_month) LOOP ЕСЛИ curCount = o_count ТОГДА l_query: = l_query || REPLACE ('TO_DATE (' '$ X $' ',' 'yyyymmdd' ') как DAY_ $ X $ _TOTAL', '$ X $', x.time_stamp); ELSE l_query: = l_query || REPLACE ('TO_DATE (' '$ X $' ',' 'yyyymmdd' ') как DAY_ $ X $ _TOTAL,', '$ X $', x.time_stamp); END IF; END LOOP; l_query: = l_query || ')) ORDER BY aggregator, country'; END; –

Попробуйте добавить 2 разных dbms_output.put_line в условие if и else в цикле и повторить разные значения. Затем мы можем проверить правильность нашей логики. – Utsav

Привет @Utsav, я снова попробовал ваше предложение, если у меня в dbms_output.put_line нет результата, а в моем другом - тот же результат. Есть ли предложения? У меня нет другой идеи. Благодарю. –

Или используйте RTRIM:

  CREATE OR REPLACE PROCEDURE intl_sms_aggr (p_cursor IN OUT SYS_REFCURSOR) 
      AS 
       l_query LONG := 'SELECT * FROM ( SELECT tcsd AS Aggregator, 
           country, 
           SUM (COUNT) AS total, 
           COUNT (dest_addr) AS bnum, 
           time_stamp 
          FROM t_raw_intl_sms_aggr 
         GROUP BY tcsd, 
           COUNT, 
           country, 
           time_stamp 
         ORDER BY tcsd, 
           COUNT, 
           country, 
           time_stamp) PIVOT (SUM (total) AS total, 
               COUNT (bnum) AS bnum_total 
              FOR time_stamp 
              IN ('; 
      BEGIN 
       FOR x IN (select time_stamp from prev_month) 
       LOOP 
        l_query := l_query|| REPLACE (' TO_DATE(''$X$'',''yyyymmdd'') as DAY_$X$_TOTAL, ','$X$',x.time_stamp); 

       END LOOP; 
       l_uqery := RTRIM(l_query,','); 

       l_query := l_query || ')) ORDER BY aggregator, country'; 

       -- OPEN p_cursor FOR l_query; 
            DBMS_OUTPUT.put_line ('query: ' || l_query);
