mysql - 批量插入SQL语句

Question

我说 100 行数据要插入到 MySQL 数据库表中。
但我不想写所有 100 个 INSERT 语句。
SQL中有批量插入语句吗？？？ 如果可能，请帮助编写代码。

Answer 1

作为MySQL manual状态:

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas. Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

此外，来自 speed of INSERT 的部分:

If you are inserting many rows from the same client at the same time, use INSERT statements with multiple VALUES lists to insert several rows at a time. This is considerably faster (many times faster in some cases) than using separate single-row INSERT statements. If you are adding data to a nonempty table, you can tune the bulk_insert_buffer_size variable to make data insertion even faster. See Section 5.1.3, “Server System Variables”.
