DescriptionIBM DB2 is primarily used in large-scale applications, with good scalability and support from mainframe to single-user environments, to all common server operating system platforms.

Load (load) The load command format is similar to the import, the command keyword is load, but the following arguments are much more than the import command, and the detailed usage can refer to the DB2 documentation. Loading is similar to importing the data in the input file into the target table, and the differences between the two will be explained Step-by-step in the instance. The target table must al

Pre-configured ODBC is required to prepare content (because the DSN that is used after the use of ODBC in the text is involved) To use ODBC for the DB2 database, you must install the corresponding driver yourself. Microsoft only provides a default installed driver for its own database and Oracle database. Specific driver download and installation can own Baidu. After filling in a meaningful name for the
