They can also be used to store dates prior to the year 1970. Custom data types can also be used to store data that is not supported by the standard SQL data types, such as dates prior to the year 1970 or large numbers with more than 15 digits.

What are the Benefits of Custom Data Types?

Custom data types provide a number of benefits for SQL users. They allow users to store data that is not supported by the standard SQL data types. This can be useful for applications that require data that is not supported by the standard SQL data types.

Furthermore, custom data types can be difficult to debug, as they are not supported by the standard SQL data types.

Conclusion

Custom data types can be a useful tool for SQL users. They can be used to store data that is not supported by the standard SQL data types, such as images, documents, and audio files. Additionally, they can be used to store dates prior to the year 1970 and large numbers with more than 15 digits.
