Declaring a Transact-SQL Variable. The DECLARE statement initializes a Transact-SQL variable by: Assigning a name. The name must have a single @ as the first character. Assigning a system-supplied or user-defined data type and a length.

For numeric variables, a precision and scale are also assigned. The DECLARE statement is used to declare a variable in SQL Server. In the second step, we have to specify the name of the variable. Local variable names have to start with an at (@) sign because this rule is a syntax necessity. You can use following example for building SQL statement. DECLARE @sqlCommand varchar(1000) DECLARE @columnList varchar(75) DECLARE @city varchar(75) SET @columnList = 'CustomerID, ContactName, City' SET @city = '''London''' SET @sqlCommand = 'SELECT ' + @columnList + ' FROM customers WHERE City = ' + @city EXEC (@sqlCommand) Using sp_executesql SQL Declare variable date Declare variable date.

CREATE PROCEDURE AddBrand @BrandName nvarchar(50), @CategoryID int AS BEGIN DECLARE @BrandID int SELECT @BrandID = BrandID FROM tblBrand WHERE BrandName = @BrandName INSERT INTO tblBrandinCategory (CategoryID, BrandID) VALUES (@CategoryID, @BrandID) END You would then call this like this: EXEC AddBrand 'Gucci', 23

The variables in Transact-SQL are generally used in the batch or stored procedures. The DECLARE statement is used for declaring a variable. For example: DECLARE @str_name datatype[], @int_num datatype[]; After a variable is declared, this is initialized as NULL. Unlike other popular SQL scripting languages, SQL Notebook's DECLARE statement does not require a data type to be specified.

It's possible, but it requires using dynamic SQL. I recommend reading The curse and blessings of dynamic SQL before continuing DECLARE
