Access creates a lookup column based on your list. Lesson 3: Working with Microsoft Access Tables After you create an Access table, you can modify it, enter data into it manually or import data from somewhere else, such as Excel.
This lesson teaches you how to modify a table and enter data. Enter Records After you have created a table, you can enter data into it. When you make an entry into another field in the record, Access will automatically make an entry into the AutoNumber field. To enter data into fields that have a lookup list: 1. Click the down-arrow that appears when you click in the field. Click to select the entry you want. Press the Tab key.
Modify a Table After you create a table, you may need to modify it. You can delete columns, insert columns, or move columns. Delete Columns The Delete option permanently deletes columns and all the data contained in them.
You cannot undo a column delete. To delete columns: 1. Click and drag to select the columns you want to delete. A prompt appears. Click Yes. Access deletes the columns you selected. Insert Columns The Insert option inserts a column before the selected column. To insert a column: Lesson 4: Sorting, Filtering, and Creating Relationships You can sort Access data so you can view records in the order you want to view them, and you can filter data so you only see the records you want to see.
This lesson teaches you how to sort and filter an Access table. Access data is stored in multiple tables. Relationships join tables together so you can work with the data from multiple tables. This lesson also teaches you how to create relationships.
Sort a Table By sorting, you can put a column of information in alphabetical, numerical, or date order. You can sort in ascending order alphabetical from A to Z, lowest number to highest number, earliest date to latest date or descending order alphabetical from Z to A, highest number to lowest number, latest date to earliest date.
For example, you can sort by state and then sort within each state by city. When sorting within a sort, perform the innermost sort first. For example, if you are sorting by state and then city, sort the city first and then sort by state. To add a sort: 1. Click the column label for the column you want to sort. Activate the Home tab. Access sorts the column in ascending or descending order. To remove a sort: 1. Access clears all of the sorts you have applied.
Filter a Table You can apply a filter to see only the records you want to see. You can filter your data so only DE students display. Each time you apply a filter to a column, it replaces any previous filter you applied to that column. For example, if you apply a filter so you only see students in DE, and later you apply a filter so you only see students in NJ, Access clears the DE filter and then applies the NJ filter.
You can apply filters to multiple columns in the same table. For example, by applying a filter first to the State field and then to the Last Name field, you can see all of the students in the state of DE whose last names are Adams.
To apply a filter: 1. Click the column label for the column you want to filter. Click the Filter button. A menu appears. Uncheck the items you do not want to appear, making sure only the items you want are checked. Access filters your data and displays the word Filtered at the bottom of the window. To remove a filter: 1.
Click Clear All Filters. Access clears all the filters you have applied. Tip: After you apply a filter, you can use the Toggle Filter button to toggle the application of the filter on and off. Hide Columns There may be times when you may not want to display a certain column or set of columns. In such cases, you can temporarily hide the column or columns from view.
Later, if you want to display them column again, you can unhide them. To hide columns: To create relationships: 1. Close all tables and forms. Right-click on the tab of any Object. Click Close All. Activate the Database Tools tab.
The Relationships window appears. If anything appears in the relationships window, click the Clear Layout button in the Tools group. If you are prompted, click Yes. Click the Show Table button in the Relationships group. The Show Table dialog box appears. Activate the Tables tab if your relationships will be based on tables, activate the Queries tab if your relationships will be based on queries, or activate the Both tab if your relationships will be based on both.
Double-click each table or query you want to use to build a relationship. The tables appear in the Relationships window. Click the Close button to close the Show Table dialog box. Make sure the arrow points to the foreign key. The Edit Relationships Dialog box appears. Click the Enforce Referential Integrity checkbox. Click Create. Access creates a one-to-many relationship between the tables. Click the Save button on the Quick Access toolbar to save the relationship.
Tip: When you create a relationship, you can view the related table as a subdatasheet of the primary table. The plus sign turns into a minus - sign. If the Insert Subdatasheet dialog box opens, click the table you want to view as a subdatasheet and then click OK. Access displays the subdatasheet each time you click the plus sign in the far left column.
Click the minus sign to hide the subdatasheet. Tip: After a relationship has been created between two tables, you must delete the relationship before you can make modifications to the fields on which the relationship is based. To delete a relationship. To create a query, you open the tables or queries on which you are going to base your query in Query Design view, and then use the options in Design view to create your query. You then click the Run button to display the results.
You can save queries for later use. To open tables or queries in Query Design view: 1. Click the Query Design button in the Other group. Activate the Tables tab if you want to base your query on tables, activate the Queries tab if you want base your query on queries or activate the Both tab if you want to base your query on both tables and queries.

Display All Records and All Fields In Query Design view, each table has an option that allows you to display all of the fields and all of the records in a table.
This option appears on the field line on the drop-down menu as the table name followed by a period and an asterisk tablename.
To display all records and all fields: 1. Open a table or query in Query Design view. Click the down-arrow in the first field on the Field row and then select the tablename. The table name appears on the table line. Click the Run button. Access retrieves all of the fields and records for the table and displays them in Datasheet view.
After you run a query, you can easily change back to Query Design view and make modifications to your query or create a new query. To change to Query Design view: 1. Click the down-arrow below View in the Views group.
Click Design View. You can modify your query. Tip: You can also click the Design button in the lower-right corner of the Access window to change to Design view.
Retrieve a Single Column You can use an Access query to retrieve a single column of data. Instead of choosing the tablename. To retrieve a single column: 1. Choose the field name you want to display in the field line. Access retrieves the column you chose. Retrieve Multiple Columns You can use an Access query to retrieve multiple columns of data.
On the Field line in Query Design view, choose the field name of each field you want to retrieve in the order you want to retrieve them. To retrieve multiple columns: 1. Choose the field names you want to retrieve in the order you want to retrieve them. Access retrieves the columns you chose. Sort a Query When creating a query, you can sort the rows you retrieve in ascending or descending order by choosing the option you want on the Sort row in Query Design view.
To perform a sort: 1. Under the field you want to sort, click the down-arrow and then choose Ascending or Descending. Access retrieves the columns you chose and displays the rows in the order you specified.
Sort Multiple Columns in a Query As you learned in the previous section, you can sort the rows your query returns. You can also create sorts within a sort. For example, you can sort by state and then within a state, you can sort by last name and then by first name. You specify the sort in the order you want the sort to occur.
If you want to sort by state and then by last name within a state and then by first name within last name, you enter the sort in the following order: city, last name, first name. See our User Agreement and Privacy Policy.
