Operator in SQL Server [closed]

This operator does not exist in SQL Server, if you find it in a query or procedure you will get a Syntax Error.

However, in Pascal, Modula-2, MySQL, etc., it is an assignment operator.

Here is an example of its use in MySQL

SELECT @ejemplo := 'hola';    /*variable 'ejemplo' ahora tiene el valor de 'hola'*/
return value: 'hola'

The operator: = is an allocator and is used in some languages such as MySQL and Postgres, but not in SQL Server. There it is assigned with the symbol "="
