Worked Solution & Example Answer:5.1 Redigeer die Learners_Leerders-tabel soos volg: 5.1.1 Stel die versteekwaarde ('default value') van die Gender_Geslag-veld op 'M' - NSC Computer Application Technology - Question 5 - 2016 - Paper 1
Step 1
Stel die versteekwaarde ('default value') van die Gender_Geslag-veld op 'M'.
Answer
To set the default value of the Gender_Geslag field to 'M', navigate to the Learners_Leerders table in the database management system. Locate the Gender_Geslag field and change its default property to 'M'. This ensures that if no value is provided by the user, 'M' will be automatically assigned.
Step 2
Verander die kenmerke ('properties') van die Grade_Graad-veld om te verseker dat 'n gebruiker 'n waarde in die veld moet inskakel.
Answer
To alter the properties of the Grade_Graad field, set the 'Required' property of the field to 'Yes'. This means that the user must input a value before the form can be submitted. Without a value, an error message should prompt the user to complete this field.
Step 3
Verander die kenmerke ('properties') van die Class_Klas-veld om die volgende vereiste opsies in 'n afdroplys ('drop-down list') te vertoon: A B C D.
Answer
Modify the Class_Klas field to become a drop-down list by setting its Control Type to 'Combo Box'. Then, specify the Row Source as a list containing the options A, B, C, and D. This allows the user to select one of these options, ensuring data consistency.
Step 4
Verander die DOB_Geboortedatum-veld soos volg: - Formateer die veld om die datums in medium datum-formaat ('Medium Date') te vertoon. - Voeg 'n toevoermasker ('input mask') in die '#' simbool in plaas van die '!' simbool as 'n plekhouer te vertoon.
Answer
For the DOB_Geboortedatum field, change the format to 'Medium Date', which typically displays dates in a user-friendly way, such as 'Jan 1, 2020'. Next, to enforce a specific input format, use an input mask; set the mask to show '#' for numeric inputs, ensuring the placeholder guides the user on the expected format.
Step 5
Skep 'n valideringsreël ('validation rule') vir die Cell_SEL-veld sodat die gebruiker presies 10 karakters (van enige tipe) in dié veld moet insleutel.
Answer
Create a validation rule for the Cell_SEL field by navigating to its properties. Set the validation rule to 'Len([Cell_SEL])=10'. This ensures that any input into the field must consist of exactly 10 characters. Provide a user-friendly error message that instructs users to input exactly 10 characters if they fail to meet this requirement.
Step 6
Stoor om DIT na die frm5_2-vorm toe te voeg.
Answer
Once all the modifications have been made to the table fields and the validation rules are set, save your changes. Next, create a new form named frm5_2 based on the Learners_Leerders table. Ensure to include all fields created or modified in the previous steps in this form for proper data entry.
