There are different datatypes in PL/SQL:

1. Scalar Types: This basic data-type holds a single value, such as, number or string of characters.
2. LOB Types: This data-type specifies the location of large objects, such as, text files, images, etc.
3. Reference Types: This data-type is used to hold pointer values which generally stores the address of other program items.
4. Composite Types: This type of data is a composition of individual data that can be manipulated/processed separately as well.
