Examples ​

public Task<User> GetUserAsync([Column("user_id")] int id, [Column("is_active")] bool active);

Remarks ​

Use this attribute on method parameters to map them to specific database column names when the parameter name doesn't match the column name. This is particularly useful when working with database commands generated by source generators.
