In regards to relational database operations using the Structure Query Language (SQL), which of the following
is a value that can be bound to a placeholder declared within an SQL statement?
A.
A bind value
B.
An assimilation value
C.
A reduction value
D.
A resolution value
Explanation:
Bind parameters—also called dynamic parameters or bind variables—are an alternative way to pass data to the
database. Instead of putting the values directly into the SQL statement, you just use a placeholder like ?, :name
or @name and provide the actual values using a separate API call.
When using bind parameters you do not write the actual values but instead insert placeholders into the SQL
statement. That way the statements do not change when executing them with different values.
Incorrect Answers:
B: An assimilation value is not the correct term for a value that can be bound to a placeholder declared within
an SQL statement.
C: A reduction value is not the correct term for a value that can be bound to a placeholder declared within an
SQL statement.
D: A resolution value is not the correct term for a value that can be bound to a placeholder declared within an
SQL statement.http://use-the-index-luke.com/sql/where-clause/bind-parameters
