SQL WHERE column = everything
For anyone who NEEDS the column name in the query for whatever reason (probably dynamic SQL), a nice alternative would be SELECT * FROM table WHERE column = column
This is very similar to WHERE 1=1, however it includes the column name, which my solution required, and maybe a few others will require as well.
SELECT * FROM table
If you're generating SQL dynamically, it's
SELECT * FROM table WHERE 1=1
The 1=1 placeholder allows you to return all records, or substitute an actual condition if you're returning a subset or need additional conditional statements.

Why would someone use WHERE 1=1 AND <conditions> in a SQL clause?
Your question allow three intrepretations:
- You don't care about the column: drop the it from the where clause (or drop the where clause alltogether, if this was the only subclause)
- You want the column to be set, bit you don't care to what: Use
WHERE column IS NOT nULL - You want a search, that can also display all records from a simple SQL template:
SELECT * FROM table WHERE column LIKE '%$searchterm%'
