title: 'ClickPipes for MySQL: Supported data types'
slug: /integrations/clickpipes/mysql/datatypes
description: 'Page describing MySQL ClickPipe datatype mapping from MySQL to ClickHouse'
---

Here is the supported data-type mapping for the MySQL ClickPipe:

| MySQL Type | ClickHouse type | Notes |
| -------------------------------------------------------------------------- | ------------------------------------------ | -------------------------------------------------------------------------------------- |
| Enum | LowCardinality(String) | |
| Set | String | |
| Decimal | Decimal | |
| TinyInt | Int8 | Supports unsigned. |
| SmallInt | Int16 | Supports unsigned. |
| MediumInt, Int | Int32 | Supports unsigned. |
| BigInt | Int64 | Supports unsigned. |
| Year | Int16 | |
| TinyText, Text, MediumText, LongText | String | |
| TinyBlob, Blob, MediumBlob, LongBlob | String | |
| Char, Varchar | String | |
| Binary, VarBinary | String | |
| TinyInt(1) | Bool | |
| JSON | String | MySQL only; MariaDB `json` is just an alias for `text` with a constraint. |
| Geometry & Geometry Types | String | WKT (Well-Known Text). WKT may suffer from small precision loss. |
| Vector | Array(Float32) | MySQL only; MariaDB is adding support soon. |
| Float | Float32 | Precision on ClickHouse may differ from MySQL during initial load due to text protocols. |
| Double | Float64 | Precision on ClickHouse may differ from MySQL during initial load due to text protocols. |
| Date | Date32 | |
| Time | DateTime64(6) | The date portion is Unix epoch. |
| Datetime, Timestamp | DateTime64(6) | |
