LOB Data Types


The built-in LOB data types BLOB, CLOB, and NCLOB (stored internally) and BFILE (stored externally) can store large and unstructured data such as text, image, video, and spatial data. (Oracle SQL Language Reference LOB Data Type)


LOB data types are not supported in Snowflake. Per Snowflake's documentation, it is recommended to transform CLOB to VARCHAR, and BLOB to BINARY, however, there are several limitations.

LOB properties for tables are also not supported in Snowflake.

In the subsections, you will find transformation documentation for the following datatypes:
