Microsoft Access UNION and UNION ALL

4 stars based on 47 reviews

Imagine you have three tables containing similar data. You want all the data from those three tables in one query.

Creating one record for each entry in each table. So if table1 had 50 records table2 had 20 records and table3 had 10 records the resulting query would have 80 records in it. Query Results Why combine queries in access Note that is listed three times. This is because it appears once in table1, once in table2 and once in table3.

Design a new query. Don't bother to bring the table names in as you can't use them. That should change the query screen to a blank text box. If you haven't seen this view before it's called the SQL view of queries and it's where really sad propeller heads write their queries rather that using the intuitive interface MS gave you.

Unfortunately Microsoft decided not to give you an interface to create SQL specific queries, so you have to type it in yourself. What that means in English is. If we left out the ALL word in the why combine queries in access two statements would only have been returned once. Query Results Without ALL statement PayrollNo You can also return more why combine queries in access one field why combine queries in access seperating field names with a comma on the select statement.

All fields must be of the same type and specified in the same order. That's because the names weren't unique. One is John the other is temp. This time we are going to specify a criteria.

We want all records whose payrollno is greater than Note we have to specify the criteria twice. Once for each table. You can specify different criteria for each table if you want.

Note we have to convert the date into a string. Obviously the example given is not a useful one but knowing this trick you will soon find a use for it.

I use this trick all the time to convert flat data imported into a database into relational data without having to write a single line of code.

Microsoft Access Microsoft Access. I would like to get the total number from each table.

Is there a way to do this in Access? Sign up today x. Use a union query: I would like the results to be in the same table Do you mean query? Do you want them to be in the same row or separate rows? You might start with the original data and do a query on that. Experts, I want them on separate rows. The problem I am having now is I only want the using distinct in count in Access. That's what the union query does. Go back to the original table.

Experts, I am sorry for the confusion. My problem is not concatenating the totals into one table now. The problem I am having is counting unique values for the respective tables.

It is possible to have multiple records with the same key value. I want to count a person only once. How would I get distinct values in an access query? You keep asking this, but yes, that's what the union query does. Unique values of what? For the Girls, try something like: We are flying blind here.

Sounds like you have a table of people and a table of transactions and you want to count by gender the number of people who have had a transaction. Then create a second query to count the records from the first one. If Gender isn't in the transaction table you will need to join to the persons table in one of the queries to pick it up.
