Store sql query in variable

[qlikuser22]

Hi 

I have a select statement written in SQL. 

I want help to store the query result in a variable and use the variable in another SQL query. Please help me if there is any solution. 

Example:

Let abc = select * from table;

SQL select * from table where a =  (§abc);
