SQL Certification Training Course in Jaipur

Course Details:

SQL skills are highly strive after in web development, programming, data analysis, and reporting environments. SQL allows you to retrieve, sort, group, filter, aggregate and calculate data stored in a SQL Server database. This course is designed for people wanting to learn how to interrogate data from a relational database, how to manipulate this data (Insert, update, and delete records). We will take you through the fundamentals of SQL in a rapid, highly interactive, and effective manner.

Course Modules:

  • Modifying table structure with ALTER TABLE
  • Adding columns to an existing table
  • Removing tables with DROP TABLE

Protecting data integrity with constraints

  • Guaranteeing uniqueness with primary key constraints
  • Enforcing integrity with foreign key constraints
  • Imposing business rules with check constraints
  • Enabling and disabling constraints
  • Removing constraints with ALTER TABLE

Improving performance with indexes
