How to connect to and operate Oracle databases using JDBC Learn before. NET, ODBC was used to connect to the database, while JDBC is usually used in Java to connect to the database. Here we take the oracle database as an example to briefly summarize how to connect to and operate the database using

Five methods for JDBC to read the Sequence Value of the newly inserted Oracle Database Oracle's sequence implementation is very flexible, so it also brings about some usability issues. How to obtain the sequence value generated by the new inserted records is significantly different from other databases, this document introduces five methods for reading the Sequence Value of the newly inserted record.

The Blob field in Oracle is special. It has much better performance than the long field and can be used to save binary data such as sample slices. Writing BLOB fields is very different from writing other types of fields. Because blob itself has a cursor, you must use cursor to operate blob. Therefore, before writing blob, you must obtain the cursor to write data. How can you obtain the Blob cursor? This requires you to insert an empty blob first, whi
