The configuration process in Linux is the same as that in Windows:1. Copy the jar package of oracle JDBC to the relevant directory of MATLAB (../Matlab/Java/JAR/toolbox. The JDBC à lib (for example,/APP/Administrator/product/11.1.0/client_1/jdbc/LIB) in the Oracle 11g instal

1. Use the thin driver in client software development In terms of Java software development, Oracle database provides four types of drivers, two types of client software for application software, applets, Servlets, and so on, the other two types are used for server software such as Java stored procedures in databases. In the development of client software, we can choose the OCI driver or

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, whic

a jdbc connection string problem. If the traditional style is used and the database is deployed in the instance, the connection string should be written as follows: Jdbc: oracle: thin: @ 192.168.0.1: 1521: SSO (Assume the Instance name is SSO) If it is a pluggable database named PDBSSO, the connection string shoul

What is the execution efficiency of this write method and PreparedStatement. setExecuteBatch in JDBC, or PreparedStatement + addBatch () + executeBatch? We test the actual performance of the thr

Java + Oracle implement transactions-JDBC transactions, oraclejdbc J2EE supports JDBC transactions, JTA transactions, and container transaction. Here we will explain how to implement JDBC transactions. A jdbc transaction is controlled by a Connection object. It provides tw
