MySQL INSERT Statements: VALUES vs. SET – Which is More Efficient?

MySQL INSERT statement: Efficiency comparison between VALUES and SET

In database programming, the INSERT statement is the key to adding new records to the table. MySQL database provides two different syntaxes for INSERT statements:

• INSERT INTO table (a, b, c) VALUES (1, 2, 3)
• INSERT INTO table SET a = 1, b = 2, c = 3

Detailed explanation of the difference

The fundamental difference between the two syntaxes is the way the column values ​​are specified. In the first example, the VALUES keyword is followed by a parenthesized list of values ​​that correspond to the sequential columns in the table. In contrast, the second example uses the SET keyword to assign column names to their respective values.

Performance Considerations

Many programmers wonder about the performance differences between these two syntaxes. MySQL's documentation (https://www.php.cn/link/d0812edf466bc20c650b452513b583e7) clearly states that they are equivalent in terms of performance. Both syntaxes are equally efficient at inserting records into tables.

Summary

While both syntaxes are efficient for adding data to a MySQL table, they differ slightly in how they specify column values. However, this difference does not affect their performance, so they are options that can be used interchangeably for inserting new records.
