You can define indexes (keys), specify links between tables, and impose constraints between tables.?

Summary:SQL is divided into four main parts :(1) Data definition. (DDL) is used to define the creation and undo operations of SQL schemas, basic tables, views, and indexes.(2) Data manipulation.(DML) Data manipulation is divided into two categories: Data query and Data update.

　　expr is for Tcl-to-do math type operations. It takes all of its arguments ("2 + 2" for example) and evaluates the result as a Tcl "expression", and returns the value. Many commands expr use behind the scenes of order if to evaluate test expressions, such as, and loops. for tip: enclosing the arguments to in expr curly braces would result in faster code. So do expr{$i*10} instead of simplyexpr$i*
