What to Focus On
- A database contains related tables.
- A table contains rows and columns.
- SQL is the standard language for relational databases.
- CHAR is fixed length.
- VARCHAR is variable length.
- INT stores whole numbers.
- Constraints control allowed values.
- PRIMARY KEY uniquely identifies a record.
- FOREIGN KEY links tables.
Common Mistakes to Avoid
SQL is case sensitive, so NAME and name are different in queries.
CHAR and VARCHAR are the same, so they can be used interchangeably without thinking about length or storage.
Any all-digit value must be stored as INT.
Memory Tips
SQL is not case sensitive
Always end SQL statements with a semicolon
CREATE, ALTER, DROP are DDL
INSERT, UPDATE, DELETE are data manipulation statements
