【Answer】
This transposition involves grouping and alignment. It’s easy to do it in SPL:
| A |
|
| 1 |
=connect(“demo”) |
| 2 |
=A1.query(“SELECT *FROM tb2”) |
| 3 |
=A2.group(USERID).new(USERID,(t=~.align@s([“hair”,“weight”],TYPE).(DESCR))(3):type,t(1):hair,t(2):weight) |
A2’s data:
Result of executing A3:
A1: Connect to the database;
A2: Retrieve the data;
A3: First group and align data, and then perform the transposition.
