How to achieve batch data loading in Db2?
There are several methods for implementing bulk data loading in Db2, and below are two commonly used methods:
- Db2 offers the LOAD command to batch load data into a table. With the LOAD command, you can load data into a table from an external file or standard input. The syntax is as follows:
LOAD FROM datafile OF del INSERT INTO tablename
The datafile refers to an external file containing data, del specifies the delimiter, and tablename is the name of the table where the data will be loaded.
- Another commonly used method is to utilize the IMPORT command. This command enables the loading of data from external files into tables and offers more options to control the way data is loaded. The syntax is as follows:
IMPORT FROM datafile OF del INSERT INTO tablename
datafile refers to the data file, del is the delimiter, and tablename is the name of the target table.
Whether using the LOAD command or the IMPORT command, data can be loaded into Db2 in batches. The specific method to choose depends on the source of the data and the loading requirements.
