Скачать или смотреть SQL Joins: What is a Bind Parameter?

In this SQL joins tutorial video we'll tell you what is a bind parameter and how does it relate to SQL join operations.

A SQL bind parameter is also called a SQL bind variable - a bind parameter is used as part of a SQL query (SQL statement.)
A bind variable is used via the symbols "@" or ":", depending on the DBMS in use.

Here's an example of SQL joins with a bind parameter:
SELECT * FROM [table] WHERE [column] = @variable;

In some database management systems, a bind parameter can also be defined with an ":", so it would look like so:

SELECT * FROM [table] WHERE [column] = :variable;
