A value of 1 or -1 is converted to "True" in the Criteria row after you enter it. Tested for a No value. A value of 0 is converted to "False" in the Criteria row after you enter it.
Attachments In the Criteria row, type Is Null to include records that do not contain any attachments. Type Is Not Null to include records that contain attachments. Lookup fields There are two types of Lookup fields: those that look up values in an existing data source by using a foreign key , and those that are based on a list of values specified when the Lookup field is created.
Lookup fields that are based on a list of specified values are of the Text data type, and valid criteria are the same as for other text fields. The criteria you can use in a Lookup field based on values from an existing datasource depend on the data type of the foreign key, rather than the data type of the data being looked up.
For example, you may have a Lookup field that displays Employee Name, but uses a foreign key that is of the Number data type. If you do not know the data type of the foreign key, you can inspect the source table in Design view to determine the data types of the field.
To do this:. The data type for each field is listed in the Data Type column of the table design grid. Multivalued fields Data in a multivalued field are stored as rows in a hidden table that Access creates and populates to represent the field. In query Design view, this is represented in the Field List by using an expandable field. To use criteria for a multivalued field, you supply criteria for a single row of the hidden table.
Just below the name of the field, you will see a field representing a single value of the multivalued field. This field will have the same name as the multivalued field, with the string. For a mailing list table might include fields for first name, last name, address, city, state, zip code, and telephone number.
A record in a row on a datasheet and is a set of values defined by fields. In a mailing list table, each record would contain the data for one person as specified by the intersecting fields. The primary key is one fields or a combination of fields that holds only unique values and can identify a particular record. For example, in a Midshipman table, the "alpha" can be declared as the primary key. Design View provides the tools for creating fields in a table.
Datasheet View allows you to update, edit, and delete information records from a table. Introduction to Tables Tables are grids that store information in a database similar to the way an Excel worksheet stores information in a workbook.
Create a Table in Design View Design view allows you to build a table from scratch and set or change every available property for each field. See below for more details: Design View will allow you to define the fields in the table before adding any data to the datasheet. Field Name - This is the name of the field and should represent the contents of the field such as "Name", "Address", "Final Grade", etc.
The name can not exceed 64 characters in length and may include spaces. Data Type is the type of value that will be entered into the fields. Text - The default type, text type allows any combination of letters and numbers up to a maximum of characters per field record.
Memo - A text type that stores up to 64, characters. Number - Any number can be stored. AutoNumber - When a new record is created, Access will automatically assign a unique integer to the record in this field.
From the General options, select Increment if the numbers should be assigned in order or random if any random number should be chosen. Since every record in a datasheet must include at least one field that distinguishes it from all others, this is a useful data type to use if the existing data will not produce such values. Use this data type to embed an OLE object or link to the object in the database.
Hyperlink - A hyperlink will link to an Internet or Intranet site, or another location in the database. The Address is the only required part of the string. Description optional - Enter a brief description of what the contents of the field are. Field Properties - Select any pertinent properties for the field from the bottom pane.
Field Properties Properties for each field are set from the bottom pane of the Design View window. Field Size is used to set the number of characters needed in a text or number field.
The default field size for the text type is characters. If the records in the field will only have two or three characters, you can change the size of the field to save disk space or prevent entry errors by limiting the number of characters allowed. Likewise, if the field will require more than characters, enter a number up to The field size is set in exact characters for Text type, but options are give for numbers: Byte - Positive integers between 1 and Integer - Positive and negative integers between , and 32, Long Integer default - Larger positive and negative integers between -2 billion and 2 billion.
Single - Single-precision floating-point number Double - Double-precision floating-point number Decimal - Allows for Precision and Scale property control Format conforms the data in the field to the same format when it is entered into the datasheet. For text and memo fields, this property has two parts that are separated by a semicolon. The first part of the property is used to apply to the field and the second applies to empty fields. Text and memo format.
Hello Hello! Select one of the preset options from the drop down menu or construct a custom format using symbols explained below: Number Format Format Datasheet Entry Display Explanation , 0. This formatting consists of four parts separated by semicolons: format for positive numbers; format for negative numbers; format for zero values; format for Null values. Date format. Date Format Format Display Explanation dddd","mmmm d","yyyy Monday, January 1, dddd, mmmm, and yyyy print the full day name, month name, and year ddd","mmm ".
To change the formatting of these fields, first click the Lookup tab and change the Display Control to a text box. Go back to the General tab choices to make formatting changes. The formatting is designated in three sections separated by semicolons.
The first section does not contain anything but the semicolon must be included. The second section specifies formatting for Yes values and the third for No values. In this case, a changeable default value can be set to prevent typing the same thing numerous times. Set the Default Value property. Indexes Creating indexes allows Access to query and sort records faster.
Validation Rule Validation Rules specify requirements for the data entered in the worksheet. Validation Text A customized message can be displayed to the user when data that violates the rule setting is entered, so the user knows how to correct the errors. Input Masks An input mask controls the value of a record and sets it in a specific format. An an input mask to a field by following these steps: In design view, place the cursor in the field that the input mask will be applied to. You can use several types of criteria like text, dates read about applying criteria to text and using dates as criteria and functions.
When you need to add multiple types of criteria, you can use the OR row and also add criteria rows. Take a look at some examples of query criteria to help you get started in creating your own query criteria. Since criteria are a kind of expression, it might be more helpful to get more information about expressions.
Access More Need more help? Expand your skills. Get new features first. When you build a query in Access, you are defining specific search conditions to find exactly the data you want.
Queries are far more powerful than the simple searches or filters you might use to find data within a table. This is because queries can draw their information from multiple tables. For example, while you could use a search in the customers table to find the name of one customer at your business or a filter on the orders table to view only orders placed within the past week, neither would let you view both customers and orders at once.
However, you could easily run a query to find the name and phone number of every customer who's made a purchase within the past week. A well-designed query can give information you might not be able to find out just by examining the data in your tables. When you run a query, the results are presented to you in a table, but when you design one you use a different view. This is called Query Design view , and it lets you see how your query is put together. Click the buttons in the interactive below to learn how to navigate the Query Design view.
Click the View drop-down arrow to switch to another view of your query. In most cases, you will only need to use two main views: Datasheet view and Design view. Datasheet view lets you view your query results in the form of a table.
Design view , featured here, allows you to view and modify the design of your query. After you have designed your query, click the Run command to view the results of the query in a table.
