Can we DECLARE variable in function?
A local variable is a variable which is either a variable declared within the function or is an argument passed to a function. As you may have encountered in your programming, if we declare variables in a function then we can only use them within that function.
How do you write a variable in SQL query?
The syntax for assigning a value to a SQL variable within a SELECT query is @ var_name := value , where var_name is the variable name and value is a value that you're retrieving. The variable may be used in subsequent queries wherever an expression is allowed, such as in a WHERE clause or in an INSERT statement.
How do you DECLARE a variable number in SQL?
For example: DECLARE @site_value INT = 10; This variable declaration example would declare a variable called @site_value that is an INT datatype. It would then set the value of the @techonthenet variable to the integer value fo 10.
Can we use in () with variable SQL?
You can't use a variable in an IN clause - you need to use dynamic SQL, or use a function (TSQL or CLR) to convert the list of values into a table.
