I am a first time user of Squirrel SQL client for Oracle DB.

When I am executing the below queries it is not popping up with a user input dialog box, instead just displaying empty rows

Query

Select * from employees e 
Where e.id in ('&emp_id');

The same query when executed in SQL Developer gives an user input dialog pop up.

Tried with = and other minor tweaks, nothing has worked for me

I don't use Squirrel SQL, but - from my point of view - your code doesn't work because the engine searches for ID values that are equal to string, literally '&emp_id'.

If you want to be prompted for a parameter value, try colon:

select * from employees e where e.id = :emp_id;
                                       -------
                                       this

You used IN; that's OK as long as you enter a single value for a parameter. If you planned to use several values (e.g. comma-separated list of values), that won't work just because. There's a way to do it - for example, you'd split those values into rows and use them as a subquery, but - that's beyond your current problem. First try to make it work with a single value passed as a parameter.

Squirrel SQL does not support input prompts in the way that SQL Developer does. One way to achieve similar functionality would be to use a prepared statement instead of a prompt.

You can do this by replacing the prompt with a bind variable, like this:

Select * from employees e Where e.id = ?

Then, when you run the query, Squirrel SQL will prompt you to enter the value for the bind variable (in this case, the value of emp_id). This will be done in a separate window in Squirrel.
