What You Will Learn
- Use the SQL Server Management Studio tool to browse the definition of the database, find necessary object names, create database diagrams, and execute a SQL query to return data rows.
- Write a simple SELECT statement, returning all the columns and rows and formulate meaningful join strategy to bring together all necessary data.
- Write a WHERE clause to filter the rows based on equality, a list of values, a range of values and a wildcard character condition.
- Understand the impact on filtering based on implicit data conversions using data type precedence and how to create a proper search argument.
- Control the display of data in a SQL SELECT including renaming columns, using simple expressions with function to change output values, conditionally change the output values using CASE expressions, sort the result set, eliminate duplicate rows and control the number of rows returned.
- Write Transact-SQL queries that aggregate values across rows based a group and filter the result set based on aggregated values.
