To answer this question, we need to understand the different types of statements used in SQL or database programming.
A parameterized query is a query that includes parameters, which are placeholders for values that will be provided at runtime. These parameters help in preventing SQL injection attacks and improve query performance.
Let's go through each option to understand which one can execute parameterized queries:
A) PreparedStatement - This option is correct because a PreparedStatement in Java is a type of statement that can execute parameterized queries. It allows you to create a query with placeholders for parameters and then set the values of the parameters at runtime before executing the query. This helps in reusing the same query with different parameter values.
B) ParameterizedStatement - This option is incorrect because there is no ParameterizedStatement in Java. It is not a valid type of statement.
C) ParameterizedStatement and CallableStatement - This option is incorrect because although CallableStatement is a type of statement that can execute parameterized queries, ParameterizedStatement is not a valid type of statement in Java.
D) All kinds of Statements (i.e. which implement a sub interface of Statement) - This option is incorrect because not all types of statements in Java can execute parameterized queries. Only the PreparedStatement can execute parameterized queries, while other types of statements like Statement and CallableStatement do not support parameterized queries by default.
The correct answer is option A) PreparedStatement. This option is correct because a PreparedStatement is specifically designed to execute parameterized queries.
