Referencing resultset field in procedure

Hi folks,

I have a procedure that has a step where it performs a simple SQL to return a single value from a table.  In this case returning a simple timestamp field in nvarchar format;

myStamp = select theTime from MYSCHEMA.TABLE where condition = 'x'

If I debug my procedure I can see my variable myStamp as a table type and I can right click on the variable to see the results of the table.  The table contains 1 row with the value '20140508133257'.

But now I want to reference this value later on inside the same procedure however I can't figure out the syntax.  I tried this for example;

searchStamp NVARCHAR(45) := '';

myStamp = select theTime from MYSCHEMA.TABLE where condition = 'x';

searchStamp = myStamp.theTime;

How can I reference the single field in the single row of my resultset so i can use it further on in my procedure?  If I were looping through a cursor I would do this with something like current_row.theTime but in this case I'm avoiding a cursor.

Thanks!
