Question

I have a database table with a few thousand entries. A part of the entries (~20%) have been entered with a fully capitalized strings in the ‘name’ column.

Example:

id | name
---------
1 | THOMAS GOLDENBERG
2 | Henry Samuel
3 | GIL DOFT
4 | HARRY CRAFT
5 | Susan Etwall
6 | Carl Cooper

How would an SQL query look like that selects all entries with a fully capitalized string in the name column? (i.e. in the example: those with the ID 1,3,4)

Answer 1

In MySQL it would be:

SELECT id FROM table WHERE name = UPPER(name);

I think this would work the same way in SQL Server, DB2 and Postgres.
