The INSERT Clause Without a Column List

The INSERT Clause Without a Column List

  • You can INSERT single or multiple rows at a time.
  • An INSERT without a column list requires you to provide a value for very column.
  • You must list values in the same order that they appear on the table.
  • You must explicitly use the keyword “null” for columns that allow for nulls if you do not want to provide a value.
  • You must explicitly use the keyword “DEFAULT” for columns that provide a default value if you do not want to provide one.

Code Sample:

1    USE world;
2    INSERT INTO city 
3    VALUES 
4        (DEFAULT, "San Felipe", "CHL", "Valparaiso", 64126);

Results:

(DEFAULT "San Felipe", "CHL", "Valparaiso", 64126);

  • The values order must appear in the same order they exist in the table.
  • You must enclose strings in quotes.
  • You must NOT enclose numbers in quotes.
  • You must specify all column names and provide the keyword “DEFAULT” or a literal value for columns that provide a default option.
  • If you do not want to provide a value for columns that allow null values, you must provide the keyword “null”.
