Oracle transform table from row to column

Question

I have a query:

select vrec, valnum, valte from val_tb where  
recd in (select recd from rectb where setd = 17)
AND (vid = 3 OR vid = 26 OR vid = 28);

For the results above, I get:

vrec      valnum       valte
98945823  NULL         Total
98945823  NULL         06001
98945823  16.57        NULL 
98945824  NULL         Total
98945824  NULL         06005
98945824  0.36         NULL 

I want to transform it to get:

98945823    06001   Total   16.57
98945824    06005   Total   0.36

i.e. combine results by vrec.

Is it possible to do this using Oracle SQL?

One way to differentiate between valte values can be checking if string contains only digits or not (poor solution but should work):

WITH cte( vrec,valnum, valte) AS
(
  SELECT 98945823 AS vrec,   NULL AS valnum,'Total' AS valte FROM dual
  UNION ALL SELECT 98945823, NULL,  '06001'      FROM dual
  UNION ALL SELECT 98945823, 16.57,  NULL        FROM dual
  UNION ALL SELECT 98945824, NULL,  'Total'      FROM dual
  UNION ALL SELECT 98945824, NULL,  '06005'      FROM dual
  UNION ALL SELECT 98945824, 0.36,  NULL         FROM dual
)
SELECT 
    vrec
   ,MAX(CASE WHEN REGEXP_LIKE(valte, '^[[:digit:]]*$') THEN valte ELSE NULL END)
   ,MAX(CASE WHEN NOT REGEXP_LIKE(valte, '^[[:digit:]]*$') THEN valte ELSE NULL END)
   ,MAX(valnum)
FROM cte
GROUP BY vrec;

Output:

╔═══════════╦═══════════════╦═══════════════╦═════════════╗
║   VREC    ║ MAX(CASE...)  ║ MAX(CASE...)  ║ MAX(VALNUM) ║
╠═══════════╬═══════════════╬═══════════════╬═════════════╣
║ 98945823  ║        06001  ║ Total         ║ 16.57       ║
║ 98945824  ║        06005  ║ Total         ║ 0.36        ║
╚═══════════╩═══════════════╩═══════════════╩═════════════╝

For your case exchange cte hardcoded values with:

select vrec, valnum, valte from val_tb where  
recd in (select recd from rectb where setd = 17)
AND (vid = 3 OR vid = 26 OR vid = 28);

Your data structure is very poor, so this solution is just workaround. You should really change underlying structure.
