27 Οκτ 2013 · Assuming there are not duplicate rows in AA and BB (i.e. all the same values), a full outer join is the equivalent of the union of a left join and a right join. SELECT *. FROM AA. LEFT JOIN BB ON AA.C_ID = BB.C_ID.
OUTER JOINs. An OUTER JOIN is used to retrieve records from multiple tables while preserving records from one of the tables, even if there is no matching record in the other table. There are two types of OUTER JOINs that the Access database engine supports: LEFT OUTER JOINs and RIGHT OUTER JOINs.
I wanted to do a full join, but the Access query designer properties window on the join allows me to choose ALL from table A and matching from table B, ALL from table B and matching from table A, or only those which match in both A and B.
Full outer joins: all the data, combined where feasible. In some systems, an outer join can include all rows from both tables, with rows combined when they correspond. This is called a full outer join, and Access doesn’t explicitly support them. However, you can use a cross join and criteria to achieve the same effect.
The FULL OUTER JOIN keyword returns all records when there is a match in left (table1) or right (table2) table records. Tip: FULL OUTER JOIN and FULL JOIN are the same.
To do this, create outer joins. Inner joins only display data when there is a matching ID in both connected data sources. For example, if you want to display the products and quantities sold, you create an inner join between the Products and Order Details tables.
Simulate a full outer join in Access SQL. Access gives us a partial implementation of the Structured Query Language (SQL) but it doesn't include the ability to return a full outer join between two tables.
