MSSQL Statements Syntax

Select Statement
Update Statement

Delete Statement

Select Statement: Syntax 1: SELECT column_1, column_3
                     FROM Table
Example: SELECT ID, Name

Syntax 2: SELECT * FROM Table (meaning - select all columns).

Example: SELECT * FROM tbl_customers

Syntax 2: UPDATE Table
                    column_1 = 'value'                    WHERE column_2 = 'Dependency_Term'
Example: UPDATE tbl_customers
