A handy use of this operator is to alias a routine's return value to $_ and to do additional manipulation with it, such as printing or returning it to caller. Since the andthen operator short-circuits, statements on the right-hand side won't get executed, unless left-hand side is defined (tip: Kappa logo top Multicolour Marcelo Burlon Ebay Jj0g8JW0t
are never defined, so you can handle them with this operator).

sub load-data {
rand > .5 or return ; # simulatedloaddatafailure;returnNil
( rand > .3 ?? ' error ' !! ' gooddata ' ) xx 10 # ourloadeddata
load-data . first : / good / andthen say " $ _ isgood " ;
# OUTPUT:«(gooddataisgood)␤»
load-data () andthen . return ; # returnloadeddata,ifit'sdefined
die " Failedtoloaddata!! " ;

The above example will print good data is good only if the subroutine returned any items that match /good/ and will die unless loading data returned a defined value. The aliasing behaviour lets us pipe the values across the operator.

The andthen operator is a close relative of with statement modifier , and some compilers compile with to andthen , meaning these two lines have equivalent behaviour:

. A database transaction is a unit of work, typically encapsulating a number of operations over a database (e.g., reading a database object, writing, acquiring , etc.), an abstraction supported in database and also other systems. Each transaction has well defined boundaries in terms of which program/code executions are included in that transaction (determined by the transaction's programmer via special transaction commands).

The acronym describes some ideal properties of a database transaction: 2018 For Sale Tory Burch Linen MidRise Pants Outlet Shop EIjziEz

A database built with one DBMS is not portable to another DBMS (i.e., the other DBMS cannot run it). However, in some situations, it is desirable to move, migrate a database from one DBMS to another. The reasons are primarily economical (different DBMSs may have different Stella McCartney 2017 Corset Blazer Low Shipping For Sale Cheap Price Buy Discount Free Shipping Amazing Price Cheap Sale Manchester Great Sale Outlet 100% Guaranteed CinRBWl8DG
or TCOs), functional, and operational (different DBMSs may have different capabilities). The migration involves the database's transformation from one DBMS type to another. The transformation should maintain (if possible) the database related application (i.e., all related application programs) intact. Thus, the database's conceptual and external architectural levels should be maintained in the transformation. It may be desired that also some aspects of the architecture internal level are maintained. A complex or large database migration may be a complicated and costly (one-time) project by itself, which should be factored into the decision to migrate. This in spite of the fact that tools may exist to help migration between specific DBMSs. Typically, a DBMS vendor provides tools to help importing databases from other popular DBMSs.
