Sliding certain records to the end of a run of the same date (3 answers)

Closed 2 years ago.

For example, I have a table in Oracle db where the values in a column are:

A
B
C
D

I would like to fetch the following output from the table(here, B,C,D are in alphabetical order and A is put to the last):

B
C
D
A

Note: They have a unique key with the column if that helps.

回答1:

Have a case expression in the ORDER BY to put A rows at the end:

order by case when columnname = 'A' then 1 else 0 end, columnname
