You have access to company databases and your job may require you to retrieve data from those databases. Retrieval of information from a database is dependent on precisely ordered logic and specific information. This course will help you to use Structured Query Language (SQL) as a tool to implement that logic and define instructions. Upon successful completion of this course, students will be able to:
- Connect to the SQL Server database and execute a simple query.
- Include a search condition in a simple query.
- Use various functions based on the data types to perform calculations on data.
- Organize the data obtained from the query before it is displayed on the screen.
- Retrieve data by combining information from multiple tables.
- Format the output, save the result, and generate a report.
- Code subqueries to generate query output.
- Manipulate table data by inserting, updating, and deleting records in a table.
- Create a simple table, create tables with constraints, modify the table structure, and delete tables.
- Create views, manipulate data through views, modify the view structure, and drop views.
- Create indexes on table columns and drop inefficient indexes.
To ensure your success, we recommend you have basic end-user computer skills and some familiarity with database terminology and structure.
