Prepared or Parameterized Statements in Database System

In this post, I demonstrate basic practical about prepared statements of MySQL.

You can write or create prepared statement in MySQL but this is not an efficient way because the binary protocol through a prepared statement API is better.

But still you can write and even this doesn’t require any other programming you can directly write in SQL.
You can use a prepared statement for MySQL Client program.You can also use a prepared statement in a stored procedure for the dynamic SQL approach.

Below is a small practical demonstration of this:

Let’s first create sample table and data.

Create prepared statement:

You can see ‘ ? ‘ in WHERE clause. This ‘ ? ‘ means require parameter in this field you can pass parameter during execution of Prepared Statement.

Execute Prepared Statement:

Result is:

De-allocate prepared statement:

You can also set max_prepared_stmt_count this system variable to guard creation of too many prepared statements.
