Solution to Activity 6.1

The solution to this activity is as follows:

  1. Right-click on the members table in the Tables list to view all records:

Figure 16.41 – Records from the members table

  1. Locate the record with the ID number of 7 and confirm that the record belongs to Darby Marielle Collins.
  2. Examine the DOB column for the record and confirm that the date is NOT January 11, 1990.
  3. Create a new SQL tab to create your query; your SQL will be similar to the following SQL code:
    UPDATE vw_members_all
    SET DOB = "1990-01-11"
    WHERE ID=7;
  4. After running the SQL, reload the members table to view the records:

Figure 16.42 – Members data reloaded after the record update

  1. Examine the DOB column for the ID 7 record and confirm that the date is now January 11, 1990.

You have now confirmed that you can update particular views; here, we just updated a field, but you can insert new records...
