# Table Schema

#### Syntax

```javascript
function TableSchema(name, primKey, indexes, instanceTemplate) {
    /// <param name="name" type="String"></param>
    /// <param name="primKey" type="IndexSpec"></param>
    /// <param name="indexes" type="Array" elementType="IndexSpec"></param>
    /// <param name="instanceTemplate" type="Object"></param>
    this.name = name;
    this.primKey = primKey;
    this.indexes = indexes;
    this.instanceTemplate = instanceTemplate;
    this.mappedClass = null;
}
```

#### Properties

**indexes : Array\<IndexSpec>**

List of indexes properties.

**instanceTemplate : Object**

Object populated with indexed properties. In case Table.defineClass() or Table.mapToClass() has been used, also non-indexed properties will be part of the template.

This property is used internally by Dexie to help out IDE with code completion.

**mappedClass : Function**

In case Table.defineClass() or Table.mapToClass() has been used, the mapped constructor function will be stored in this property.

**name : String**

The name of the object store.

**primKey : IndexSpec**

Specification of primary key.

#### Description

Primary key and indexes for the object store (Table).

#### Sample

```javascript
var db = new Dexie("MyDB");
db.version(1).stores({friends: "++id,name"});

alert ("Primary key: " + db.friends.schema.primKey.keyPath); // Will alert ("id");
```
