Thiết lập lược đồ Oracle 11g R2 :

CREATE TABLE tbl ( "mod", "floor", "Remaining Counts", CountType ) AS
          SELECT 'dz-P-1A', 1,    37, 'CycleCount' FROM DUAL
UNION ALL SELECT 'dz-P-1D', 1,   321, 'CycleCount' FROM DUAL
UNION ALL SELECT 'dz-P-1T', 1,    16, 'CycleCount' FROM DUAL
UNION ALL SELECT 'dz-P-2A', 2,    25, 'CycleCount' FROM DUAL
UNION ALL SELECT 'dz-R-1T', 1,  3318, 'CycleCount' FROM DUAL
UNION ALL SELECT 'dz-P-1A', 1,  6351, 'SimpleBinCount' FROM DUAL
UNION ALL SELECT 'dz-P-1D', 1,   121, 'SimpleBinCount' FROM DUAL
UNION ALL SELECT 'dz-P-2A', 2, 12638, 'SimpleBinCount' FROM DUAL
UNION ALL SELECT 'dz-R-1F', 1,    68, 'SimpleBinCount' FROM DUAL
UNION ALL SELECT 'dz-R-1O', 1,    47, 'SimpleBinCount' FROM DUAL
UNION ALL SELECT 'dz-R-1T', 1,  2051, 'SimpleBinCount' FROM DUAL;

Truy vấn 1 :

PIVOT sử dụng SUM( CASE ... ) tuyên bố:

SELECT CountType,
       SUM( CASE "mod" WHEN 'dz-P-1A' THEN "Remaining Counts" END ) AS "P-1-A",
       SUM( CASE "mod" WHEN 'dz-P-2A' THEN "Remaining Counts" END ) AS "P-2-A",
       SUM( CASE "mod" WHEN 'dz-R-1T' THEN "Remaining Counts" END ) AS "R-1-T",
       SUM( CASE "mod" WHEN 'dz-R-1F' THEN "Remaining Counts" END ) AS "R-1-F",
       SUM( CASE "mod" WHEN 'dz-R-1O' THEN "Remaining Counts" END ) AS "R-1-O",
       SUM( CASE "mod" WHEN 'dz-P-1B' THEN "Remaining Counts" END ) AS "P-1-B",
       SUM( CASE "mod" WHEN 'dz-P-1D' THEN "Remaining Counts" END ) AS "P-1-D"
FROM   tbl
GROUP BY CountType

Kết quả :

|      COUNTTYPE | P-1-A | P-2-A | R-1-T |  R-1-F |  R-1-O |  P-1-B | P-1-D |
|----------------|-------|-------|-------|--------|--------|--------|-------|
| SimpleBinCount |  6351 | 12638 |  2051 |     68 |     47 | (null) |   121 |
|     CycleCount |    37 |    25 |  3318 | (null) | (null) | (null) |   321 |

Truy vấn 2 :

Sử dụng chuyển vị PIVOT:

SELECT * FROM (
   SELECT SUBSTR( "mod", 4 ) AS "mod",
          "Remaining Counts",
          CountType
   FROM   tbl t
)
PIVOT
(
   SUM("Remaining Counts")
   FOR "mod" IN ( 'P-1A', 'P-2A', 'R-1T', 'R-1F', 'R-1O', 'P-1B', 'P-1D' )
)

Kết quả :

|      COUNTTYPE | 'P-1A' | 'P-2A' | 'R-1T' | 'R-1F' | 'R-1O' | 'P-1B' | 'P-1D' |
|----------------|--------|--------|--------|--------|--------|--------|--------|
| SimpleBinCount |   6351 |  12638 |   2051 |     68 |     47 | (null) |    121 |
|     CycleCount |     37 |     25 |   3318 | (null) | (null) | (null) |    321 |
