Symptom
You have a data set in the form of
- Column names = A,B,C,D
- Row Values are P or Q
A | B | C | D |
P | Q | Q | P |
Q | P | Q | Q |
P | P | Q | Q |
You want to change the data set to appear with summaries of P and Q for each column, in the form of
- Column names = Column,PTotal,QTotal
- Row values are A-D, and Sum
Column | PTotal | QTotal |
A |
2 | 1 |
B | 2 | 1 |
C | 0 | 3 |
D | 1 | 2 |
Resolution
On the original dataset, use a query that summarizes each column, and then performs a union of all, into one data set.
*Note that the syntax below will not work in all databases, so you would need to do a little research to find equivalent syntax for your version/type
SELECT `A` as [Column],
PTotal = CASE ColumnA
When ColumnA = 'P' then 1
Else 0
END
QTotal = CASE ColumnA
When ColumnA = 'Q' then 1
Else 0
END
FROM Table
UNION ALL
SELECT `B` as [Column],
PTotal = CASE ColumnB
When ColumnB = 'P' then 1
Else 0
END
QTotal = CASE ColumnB
When ColumnB = 'Q' then 1
Else 0
END
FROM Table
UNION ALL
SELECT `C` as [Column],
PTotal = CASE ColumnC
When ColumnC = 'P' then 1
Else 0
END
QTotal = CASE ColumnC
When ColumnC = 'Q' then 1
Else 0
END
FROM Table
UNION ALL
SELECT `D` as [Column],
PTotal = CASE ColumnD
When ColumnD = 'P' then 1
Else 0
END
QTotal = CASE ColumnD
When ColumnD = 'Q' then 1
Else 0
END
FROM Table
