Java obtains the CLOB field in Oracle and converts it to String: try {PreparedStatement stmt = session.
Java cannot directly insert Clob Data Types in Oracle, but it can write or read clob data in the form of a stream. The online code is not too much, I have summarized and summarized the online materials. For details, refer to the Code:

When creating a knowledge base, it is obviously not enough to store articles with common VARCHAR2. There are only 4000 bytes in the partition, and there are not many words in it,
The CLOB data type can store up to 8 GB of data. However, this field
One part of the most recent project is news management. The type of news content in the database is varchar2, and the maximum size of news content is 4000 bytes. You need to enter more bytes, so we have to increase it by changing its type from
