# PartiQL data types for DynamoDB
<a name="ql-reference.data-types"></a>

The following table lists the data types you can use with PartiQL for DynamoDB.


| DynamoDB data type | PartiQL representation | Notes | 
| --- | --- | --- | 
| Boolean | TRUE \| FALSE | Not case sensitive. | 
| Binary | N/A | Only supported via code. | 
| List | [ value1, value2,...] | There are no restrictions on the data types that can be stored in a List type, and the elements in a List do not have to be of the same type. | 
| Map | { 'name' : value } | There are no restrictions on the data types that can be stored in a Map type, and the elements in a Map do not have to be of the same type. | 
| Null | NULL | Not case sensitive. | 
| Number | 1, 1.0, 1e0  | Numbers can be positive, negative, or zero. Numbers can have up to 38 digits of precision. | 
| Number Set | <<number1, number2>> | The elements in a number set must be of type Number. | 
| String Set | <<'string1', 'string2'>> | The elements in a string set must be of type String. | 
| String | 'string value' | Single quotes must be used to specify String values. | 

## Examples

The following statement demonstrates how to insert the following data types: `String`, `Number`, `Map`, `List`, `Number Set` and `String Set`.

```
INSERT INTO TypesTable value {'primarykey':'1', 
'NumberType':1,
'MapType' : {'entryname1': 'value', 'entryname2': 4}, 
'ListType': [1,'stringval'], 
'NumberSetType':<<1,34,32,4.5>>, 
'StringSetType':<<'stringval','stringval2'>>
}
```

The following statement demonstrates how to insert new elements into the `Map`, `List`, `Number Set` and `String Set` types and change the value of a `Number` type.

```
UPDATE TypesTable 
SET NumberType=NumberType + 100 
SET MapType.NewMapEntry=[2020, 'stringvalue', 2.4]
SET ListType = LIST_APPEND(ListType, [4, <<'string1', 'string2'>>])
SET NumberSetType= SET_ADD(NumberSetType, <<345, 48.4>>)
SET StringSetType = SET_ADD(StringSetType, <<'stringsetvalue1', 'stringsetvalue2'>>)
WHERE primarykey='1'
```

The following statement demonstrates how to remove elements from the `Map`, `List`, `Number Set` and `String Set` types and change the value of a `Number` type.

```
UPDATE TypesTable 
SET NumberType=NumberType - 1
REMOVE ListType[1]
REMOVE MapType.NewMapEntry
SET NumberSetType = SET_DELETE( NumberSetType, <<345>>)
SET StringSetType = SET_DELETE( StringSetType, <<'stringsetvalue1'>>)
WHERE primarykey='1'
```
