db2 timestamp

Original post http://hi.baidu.com/rich0411/blog/item/fa0c61ee3a68502e2df534bc.html The so-called data movement in DB2 includes: 1. Import Data) 2. Data Export (Export) 3. Load) Both import and load use DB2 commands to save data in files of a certain format to tables in the database.Export refers to saving the data in the table of the DB2 database to a file of a

The above formats are just examples. I will use them as an exercise so that readers can discover other formats themselves. Sometimes, you need to know the time difference between two timestamps.

Because of the recent international go to Oracle on MySQL, this inevitably involves time zone and timestamp issues. Do an experiment and summarize.OracleFirst look at the definition of Oracle Concepts for timestamp:The TIMESTAMP data type is an extension of the DATE data type. It Stores fractional seconds in addition to the information stored in the DATE data type. TIMESTAMPThe data type is useful for stori

The following articles mainly introduce the peer-to-peer Q replication Configuration between three points. We all know that peer-to-peer Q replication is one of DB2 Q replication. With this peering Q-replication, data changes on any server can be transmitted to other associated servers through MQ and copied to these servers. This allows you to synchronize data between multiple database servers. This article uses an example to describe how to set up th
