DB2 Bulk Insert: Fast Data Insertion Techniques

In DB2, you can achieve bulk data insertion using the following methods:

1. Using multiple value lists with the INSERT statement: You can specify multiple value lists in one INSERT statement, with each value list corresponding to one data insertion. For example:

INSERT INTO 表名 (列1, 列2, 列3)
VALUES (值1, 值2, 值3),
       (值4, 值5, 值6),
       (值7, 值8, 值9);

1. Using SELECT clause in INSERT statement: It allows to retrieve the data to be inserted, and then use the query result as the value in the SELECT clause of the INSERT statement. For example:

INSERT INTO 表名 (列1, 列2, 列3)
SELECT 值1, 值2, 值3
FROM 源表
WHERE 条件;

1. By using the LOAD command, you can save data in a text file and then insert the data from the text file into a table in bulk using the LOAD command. For example:

LOAD FROM '文件路径'
OF DEL INSERT INTO 表名;

Please ensure that the data being inserted matches the column order and data type of the target table to avoid insertion failure or data errors.
