 | ||
| ## SQL Insert into Statement
 | ||
| 
 | ||
| To insert a record in a table you use the `INSERT INTO` statement. 
 | ||
| 
 | ||
| You can do it in two ways, if you want to insert values only in some columns, you have to list their names including all mandatory columns.  The syntax is:
 | ||
| 
 | ||
| ```sql
 | ||
| INSERT INTO table_name (column1, column2, column3, ...)
 | ||
| VALUES (value1, value2, value3, ...);
 | ||
| ```
 | ||
| 
 | ||
| The other way is inserting values to all columns in the table, it is not necessary to specify the columns names. The syntax is:
 | ||
|  
 | ||
| ```sql
 | ||
| INSERT INTO table_name 
 | ||
| VALUES (value1, value2, value3, ...);
 | ||
| ```
 | ||
| 
 | ||
| Here’s an example inserting a record in the table Person in both ways:
 | ||
| ```sql
 | ||
| INSERT INTO Person
 | ||
| VALUES (1, ‘John Lennon’, ‘1940-10-09’, ‘M’);
 | ||
| ```
 | ||
| 
 | ||
| And
 | ||
| 
 | ||
| ```sql
 | ||
| INSERT INTO Person(Id, Name, DateOfBirth, Gender)
 | ||
| VALUES (1, ‘John Lennon’, ‘1940-10-09’, ‘M’);
 | ||
| ```
 | ||
| 
 | ||
| Some SQL versions (for example, MySQL) support inserting multiple rows at once.  For example: 
 | ||
| 
 | ||
| ```sql
 | ||
| INSERT INTO Person(Id, Name, DateOfBirth, Gender)
 | ||
| VALUES (1, ‘John Lennon’, ‘1940-10-09’, ‘M’), (2, ‘Paul McCartney’, ‘1942-06-18’, ‘M’),
 | ||
| (3, ‘George Harrison’, ‘1943-02-25’, ‘M’), (4, ‘Ringo Starr’, ‘1940-07-07’, ‘M’)
 | ||
| ```
 | ||
| 
 | ||
| Note that the entire original query remains intact - we simple add on data rows encloded by paranthesis and separated by commas.
