Key ideas in SQL with Mail-Order Pharmacy Data
- In a relational database, each horizontal row represents a single distinct event or record, such as one filled order
- Each vertical column stores a specific attribute or property of that record, like medication name, dosage, or patient ID
- A complete database table collects all these rows and columns together in a rectangular structure
- SELECT * requests every single column stored in the table, pulling massive amounts of unnecessary data
- In large enterprise databases, pulling unneeded columns can cause severe query lag
- Listing only the necessary columns (e.g., SELECT col1, col2) reduces network traffic and avoids slowing down production database servers
- The AS keyword defines an alias, which renames a column in the returned results without altering the underlying table structure
- Aliasing replaces abbreviated or technical database column names with clean, human-readable labels
- The syntax places AS directly between the original column name and the desired replacement label
- The LIMIT clause restricts the maximum number of rows returned by a query to a specified integer
- LIMIT is added at the end of a query to safely sample live, massive tables without crashing or overwhelming server memory
- Without LIMIT, a query against a multi-million-row table will attempt to transfer every matching record
- A standard SELECT returns an entry for every single row, resulting in many duplicate values if multiple rows share the same data
- DISTINCT is placed immediately after SELECT to find unique entities in a dataset
- DISTINCT collapses identical values across the selected columns so each appears exactly once in the output
- A SQL query uses the WHERE clause to evaluate each row and keep only those meeting a condition
