Populating a table from two other tables

I need to populate a table named "TargetTable". The data to populate the table
will come from two different tables. One named Table1 and another named Table2 .
I need to tage the FUAD_ITS_CLERK_ID data from Table1 and the PSUS_USER_NUM
value from Table2 and put it into the target table. I am just lost when it comes to
figuring out the query for this. I know how to join the two tables, but not how to get
the end result of populating TargetTable. Can someone help me?


Table1 -- Spreadsheet
PSUS_USER_ID     FUAD_ITS_CLERK_ID    

s611581          CRAB                
c611689               LEXY                
y657888          MUNC                


Table2 -- SMT_ADMN_PSUS_PR_STE_USERS
PSUS_USER_NUM    PSUS_USER_ID
1                s611581
2                c611689
3                y657888


TargetTable -- Currently no data
PSUS_USER_NUM   FUAD_ITS_CLERK_ID





TargetTable -- After a query is run to populate TargetTable
PSUS_USER_NUM    FUAD_ITS_CLERK_ID
1                CRAB
2                LEXY
3                MUNC
