Experts,
In the following qry, I need to show all records on the left side.  Many projects do not have an associated record in the tblLetterOfCredit based on ProjectID.  I need help to show ALL records on tblProjects even if there is not a match on tblLetterOfCredit.  
How can I do this?   Please see attachment

You need to use a LEFT JOIN ... example:

SELECT Table1.*, Table2.D1
FROM Table1 LEFT JOIN Table2 ON Table1.ID = Table2.D1;

OH sweet!  that worked.  Is the only way to do a LEFT JOIN is to actually go into the SQL?  I thought I could change the JOIN type by changing the directions of the arrows.

thanks!

Left right outer And inner are the 4 types of joins.  All handy in different situations.

Sure ... you can.  That SQL was in fact the result of doing just that - see image.

NO

place two tables in the design view of a query
create a join on two fields by dragging the field from the left table to the field on the other table

now, right click on the line that joined the two fields

a window will open with three choices, select the second option

Yes, I did know of right clicking those lines between the tables and choosing the differnt options but I did this in the qry design and it seemed to not include the LEFT side join.  Anyways, I am good now.  I must have been doing something wrong.  

I see now from those pics above, that I never really paid too much attn too, that there is a name for LEFT table and RIGHT table.  

thanks for the good info.
