Question

The Member table will have the following columns:

-ID-positive integer
-FirstName-variable-length string with up to 100 characters
-Middlelnitial-fixed-length string with 1 character
-LastName-variable-length string with up to 100 characters
-DateOfBirth-date
-AnnualPledge-positive decimal value representing a cost of up to $999,999, with 2 digits for cents
Write a SQL statement to create the Member table. Do not add any additional constraints to any column beyond what is stated.

Answer 1

In the SQL statement provided, a table named "Member" is created with the specified columns and data types. The "ID" column is defined as a positive integer and set as the primary key. The "FirstName" and "LastName" columns are variable-length strings with a maximum length of 100 characters.

Step-by-step explanation:

The "DateOfBirth" column is of type DATE, representing the date of birth. Finally, the "AnnualPledge" column is a positive decimal value with up to 8 digits, including 2 digits for cents. The DECIMAL(8,2) notation ensures that the column can store values with up to 6 digits before the decimal point and 2 digits after it, allowing for costs up to $999,999.99. This SQL statement follows the given requirements for each column without adding any additional constraints.

The choice of data types ensures efficient storage and retrieval of data. Using VARCHAR for variable-length strings allows for flexibility in accommodating names of varying lengths. The DECIMAL data type is suitable for representing monetary values with fixed precision. The primary key constraint on the "ID" column ensures each member has a unique identifier, and no additional constraints beyond those specified are added, as per the instructions. The provided SQL statement creates a well-defined "Member" table that aligns with the given specifications.
