I am using Microsoft SQL Server 2008.
I have a table that looks something like this:
|======================================================|
| RespondentId | QuestionId | AnswerValue | ColumnName |
|======================================================|
| P123 | 1 | Y | CanBathe |
|------------------------------------------------------|
| P123 | 2 | 3 | TimesADay |
|------------------------------------------------------|
| P123 | 3 | 1.00 | SoapPrice |
|------------------------------------------------------|
| P465 | 1 | Y | CanBathe |
|------------------------------------------------------|
| P465 | 2 | 1 | TimesADay |
|------------------------------------------------------|
| P465 | 3 | 0.99 | SoapPrice |
|------------------------------------------------------|
| P901 | 1 | N | CanBathe |
|------------------------------------------------------|
| P901 | 2 | 0 | TimesADay |
|------------------------------------------------------|
| P901 | 3 | 0.00 | SoapPrice |
|------------------------------------------------------|
I would like to flip the rows to be columns so that this table looks like this:
|=================================================|
| RespondentId | CanBathe | TimesADay | SoapPrice |
|=================================================|
| P123 | Y | 3 | 1.00 |
|-------------------------------------------------|
| P465 | Y | 1 | 0.99 |
|-------------------------------------------------|
| P901 | N | 0 | 0.00 |
|-------------------------------------------------|
(the example data here is arbitrarily made up, so its silly)
The source table is a temp table with approximately 70,000 rows.
What SQL would I need to write to do this?
Update
- I don't even know if PIVOT is the right way to go.
- I don't know what column to PIVOT on.
- The documentation mentions
<aggregation function>and<column being aggregated>and I don't want to aggregate anything.
Thanks in advance.
