What You Will Learn!
- Define basic SQL terminology and list the seven types of clauses in an SQL statement.
- Write an SQL query that retrieves data from one table.
- Clean your query results by sorting, filtering, and adding column aliases.
- Use the WHERE clause to filter results based on comparisons to numbers and strings.
- Write an SQL query that retrieves data from multiple tables using inner joins and WHERE clause joins.
- Use outer joins to retrieve results where one of the tables does not have matching records.
- Use date functions to format dates in your results (DATEPART, DATENAME) and to calculate the difference between two dates (DATEDIFF).
- Concatenate columns using string functions (+, TRIM) and summarize a column using aggregate functions (SUM, AVG).
- Collect data across multiple records and group the results using the GROUP BY clause and filter based on grouped data using the HAVING clause.
- Use subqueries to retrieve more complex results that cannot be achieved with a single SQL query.
