     { sql_statement | statement_block } 
END 
-- Azure SQL Data Warehouse and Parallel Data Warehouse
BEGIN
     { 
    sql_statement | statement_block 
     } 
END

{ sql_statement | statement_block }

Is any valid Transact-SQL statement or statement grouping as defined with a statement block. To define a statement block (batch), use the control-of-flow language keywords BEGIN and END. Although all Transact-SQL statements are valid within a BEGIN...END block, certain Transact-SQL statements should not be grouped together within the same batch (statement block).

In the following example, BEGIN and END define a series of SQL statements that run together. If the BEGIN...END block are not included, the following example will be in a continuous loop.

-- Uses AdventureWorks

DECLARE @Iteration Integer = 0
WHILE @Iteration <10
BEGIN
    SELECT FirstName, MiddleName 
    FROM dbo.DimCustomer WHERE LastName = 'Adams';
SET @Iteration += 1
END;
