However, to be compliant with the ANSI standard, they all support at least the major commands (such as SELECT, UPDATE, DELETE, INSERT, WHERE) in a similar manner.
SQL is a very useful and important language in database development and manipulation . There are several ways to perform numerous task using SQL and it's always useful to share new ideas and ways to make us work more efficiently using SQL.
A common task that you may have to perform in a live production environment is bulk updates, deletions or inserts . These tasks can be both time consuming and delicate if one is not focussed. By delicate I mean mistakes could be made that can cause problems in a live production environment if one is not switched on and focussed.
Microsoft excel has been a very useful tool to me when i have had to do bulk updates ,deletions and inserts. It saves so much time and helps you avoid errors especially with bulk deletions. With excel i am able to quickly build simple to complex SQL queries that i can you execute various bulk sql tasks.
In this course i will show you how to build SQL scripts from scratch step by step that you will use during the course to execute insert and update bulk tasks. The skills you will learn on this course will help you confidently approach any bulk SQL request task you in a live production environment.
