LONGVARCHAR (String)

Supported by ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The LONGVARCHAR data type represents a variable length string type, or java.lang.String in Java, or Types.LONGVARCHAR in JDBC.

This data type is mostly offered as a compatibility type as the difference between this type and other variable length binary types like VARCHAR (String) and CLOB (String) is not very well defined.
