Question

In a SQL query like this:

SELECT *
FROM MyTable
WHERE x = 5;

is it possible to modify the WHERE condition so that SELECT looks for every value of x? Something like (wrong syntax):

SELECT *
FROM MyTable
WHERE x = ANY_VALUE;

The reason behind this question is that I have to parse and modify some SQL queries through some C++ code I am writing. I know in this case I could just remove or comment the whole WHERE condition, but this is a simplification.

Thank you.

In cases like this, you normally would do something like this:

SELECT *
FROM MyTable
WHERE x = SOME_VALUE OR 1 = 1;

SOME_VALUE is arbitrary, it can be anything matching the type of the column, because the WHERE clause will always be true because of the second part.
