Find the SQL statement below that is equal to the following: SELECT NAME FROM CUSTOMER WHERE STATE = 'VA';
A. SELECT NAME IN CUSTOMER WHERE STATE IN ('VA');
B. SELECT NAME IN CUSTOMER WHERE STATE = 'VA';
C. SELECT NAME IN CUSTOMER WHERE STATE = 'V';
D. SELECT NAME FROM CUSTOMER WHERE STATE IN ('VA');
Answer: Option D
Solution (By Examveda Team)
Option A: SELECT NAME IN CUSTOMER WHERE STATE IN ('VA'); - This statement is incorrect because it uses "IN" incorrectly. The "IN" keyword is used to specify multiple possible values for a column, not for filtering by a single value.Option B: SELECT NAME IN CUSTOMER WHERE STATE = 'VA'; - This statement is incorrect because it uses "IN" incorrectly. Similar to Option A, "IN" is not used for single value comparisons.
Option C: SELECT NAME IN CUSTOMER WHERE STATE = 'V'; - This statement is incorrect because it does not match the specified condition 'VA'.
Option D: SELECT NAME FROM CUSTOMER WHERE STATE IN ('VA'); - This statement is correct. It retrieves the NAME column from the CUSTOMER table where the STATE column has the value 'VA'.
Conclusion:
To achieve the SQL statement "SELECT NAME FROM CUSTOMER WHERE STATE = 'VA';", the correct SQL statement is Option D: SELECT NAME FROM CUSTOMER WHERE STATE IN ('VA');. This option correctly filters rows where the STATE column equals 'VA'.
