If you want to find beginning or end values, omit the quotation marks, wildcard character, and the ampersand (&) that come before the opening bracket to find the beginning value – or omit the same things that follow t he brackets to match the ending of a field value.
Access will now match values that contain the parameter string. When you switch back to Datasheet view to run the query, Access prompts you, but without the brackets, the word Like, or the wildcard characters. So, if you wanted to search for titles in the query, you would enter:
Go to the field where you want to apply a parameter. To do this, open a query, then go to Design view. You can do this using Like with wildcard characters. An example is if you want a query to match a text string in any part of a field. If you want to add variability into your parameter query, you can use wildcards. You can enter the names of the parameters, and the data types, in the order that you want them to appear. Now click Parameters in the Show/Hide group. To do this, go to the Design view of your query, then click the Design tab. But what if you want to change the order in which they appear? You'd see the prompt from the first parameter that you entered, etc. When you enter parameters for your query, the prompts appear the way they do in Design view, from left to right. Now, go back to Datasheet view to run the query.Īccess now prompts you for values for your parameter in a dialogue box, as shown below:Īccess now shows us the results of our query:
#Microsoft access criteria full
You can resize the columns by clicking and dragging on the edge of the column to make it wider, to see the full values.
We enter that in the Date Purchased field. We're going to enter: Between And to see all books purchased within a specified time frame. The brackets indicate that Access should look for a field, or ask the user for a field if there is none. You will need to add a Date Purchased field to the Books table, and enter some data. This was the query we ran to see purchased books. It contains the title of the book and the date it was purchased. You can see the one we've selected below. The first thing you do is select the query for which you want to add a parameter to. However, wouldn't it be a lot easier if Access prompted you to enter a date? The good news is that you can do this using a parameter query. The criteria tells Access that you want all books added after a certain date (the date you last ran the query).
This shows the date you purchased the book. To do this, you add criteria to a DateAdded field. So, you want the query to show all the new books that you've added SINCE you last ran the query and sent out the list to your friends. Criteria eliminates the expression "looking for a needle in a haystack."īut let's say when running a query, you want to know (using our book collection database as an example) how many books you've recently added to your collection because you share this information with friends who might want to read them. We'll teach you exactly what a parameter query is and how you can create them.Īs you already know, you use criteria to narrow down the results you receive in a query. Don't worry if that doesn't make a bit of sense right now. Whenever you want a query to ask for input each time you run the query, you create what's called a parameter query in Access 2013.
