Final answer:
To modify a query in a database, create a copy and rename it, remove criteria, add calculated fields for LostCredits and TuitionPayments, format outputs, and add summary calculations for TuitionDue and TuitionPayments before saving and closing the query.
Step-by-step explanation:
To address your question on creating and modifying a query in a database system, here's a step-by-step guide:
Create a copy of the "Transfer Credits" query and rename it to "Transfer Calculations".
Open the new query in Design view and remove any criteria from the AdmissionDate field.
To create the calculated field LostCredits, in the first empty field cell, enter:
LostCredits: [CreditsEarned] - [CreditsTransferred]
For TuitionPayments, use the payment function PMT: TuitionPayments: -Pmt([InterestRate]/100/12, 4, [TuitionPayment], 0, 0)
Ensure you replace [InterestRate] with 2.5 and [TuitionPayment] with the student's tuition payment. Format this field as Currency.
Add another calculated field named FirstPayment using the expression: FirstPayment: [AdmissionDate] + 30
Run the query to ensure that data in the three calculated fields appears correct.
Add a total row to summarize the TuitionDue and average the TuitionPayments.
Save and close the query.
Each step represents a crucial part of modifying a query to include calculated fields and formatting outputs in a database application.
