INSERT INTO table VALUES vs. INSERT INTO table SET: Which MySQL Syntax Should You Use?

MySQL data insertion: Comparison of INSERT INTO table VALUES and INSERT INTO table SET

MySQL provides two syntaxes for inserting data into tables:

1. INSERT INTO table VALUES ...: This syntax explicitly specifies the value to be inserted into each column.
2. INSERT INTO table SET: This is MySQL-specific syntax, which assigns values ​​to columns individually.

Example:

-- INSERT INTO table VALUES ...
INSERT INTO table (a, b, c) VALUES (1, 2, 3);

-- INSERT INTO table SET
INSERT INTO table SET a = 1, b = 2, c = 3;

Equivalence:

Both syntaxes are equivalent in terms of inserting data into tables. The first syntax conforms to the SQL standard, while the second is an extension to MySQL.

Performance:

Performance-wise, there is no significant difference between the two syntaxes. Both are equally efficient and produce the same execution plan.

Usage scenarios:

• INSERT INTO table VALUES ...: Use this syntax when you need to explicitly specify the value of each column. It is more suitable for inserting a small number of rows.
• INSERT INTO table SET: Use this syntax when you need to insert multiple rows with different column values. For inserting large amounts of data, it is more convenient and concise.
