Oracle is a relational database technology.

PLSQL stands for "Procedural Language extensions to SQL", and can be used in Oracle databases. PLSQL is closely integrated into the SQL language, yet it adds programming constructs that are not native to SQL.

We've categorized Oracle and PLSQL into the following topics:

Data Types Literals (Constants) Declaring Variables Is Null / Is Not Null Primary Keys Foreign Keys Unique Constraints Check Constraints Indexes Functions (Built-In) - Alphabetical Functions (Built-In) - Category Creating Functions Creating Procedures Creating Triggers Exception Handling Oracle Error Messages Loops and Conditional Statements Sequences (Autonumber) Transactions Cursors Oracle System Tables Grant/Revoke Privileges Roles (set of privileges) Change Password Synonyms (create, drop) Question & Answer
