James,
SELECT Table1.*, Table2.Name ;
    FROM Table1 LEFT JOIN Table2 ;
    ON Table1.Comp_no = Table2.Comp_no ;
    INTO CURSOR TableTemp
This will give you all records in Table1. The ones with a match in Table2 will have the Name filled in, the others will have .NULL. in that field. If you don't want the nulls, you can use NVL(Table2.Name, SPACE(30)) AS Name.

Another way is to use:
SELECT Table1.*, ;
    LOOKUP(Table2.Name, Table1.Comp_no, Table2.Comp_no, [Comp_no]) ;
    FROM Table1 ;
    INTO CURSOR TableTemp
