A table is a group of data stored in a database.
|
||
|
||
To create a table in a database you use the `CREATE TABLE` statement. You give a name to the table and a list of columns with its datatypes.
|
||
|
||
```
|
||
CREATE TABLE TABLENAME(Attribute1 Datatype, Attribute2 Datatype,........);
|
||
```
|
||
|
||
Here’s an example creating a table named Person:
|
||
```sql
|
||
CREATE TABLE Person(
|
||
Id int not null,
|
||
Name varchar not null,
|
||
DateOfBirth date not null,
|
||
Gender bit not null,
|
||
PRIMARY KEY( Id )
|
||
);
|
||
```
|
||
|
||
In the example above, each Person has a Name, a Date of Birth and a Gender. The Id column is the key that identifies one person in the table. You use the keyword `PRIMARY KEY` to configure one or more columns as a primary key.
|
||
|
||
A column can be `not null` or `null` indicating whether it is mandatory or not.
