# MySQL Import Integration

This article describes how to use the data connector for MySQL, which allows you to directly import data from MySQL to Treasure Data.

For sample workflows on importing data from MySQL, view [Treasure Boxes](https://github.com/treasure-data/treasure-boxes/tree/master/td_load/mysql).

## Prerequisites

- Basic knowledge of Treasure Data
- Basic knowledge of MySQL
- A MySQL instance that is reachable from Treasure Data


If you are using MySQL Community Server 5.6 and 5.7 and want to use SSL, set the parameters enabledTLSProtocols and TLSv1.2 to resolve a compatability issue with the underlying library of the connector. For other MySQL versions, the integration will try to use the highest TLS version automatically.

## Create a New Authentication

When you configure a data connection, you provide authentication to access the integration. In Treasure Data, you configure the authentication and then specify the source information.

1. Open **TD Console**.
2. Navigate to **Integrations Hub** >  **Catalog**
3. Search for and select MySQL.
4. Select Create
5. The following dialog opens.

| **Port** | The connection port on the remote instance,MySQL default is 3306. |
| **Username** | Username to connect to the remote database. |
| **Password** | Password to connect to the remote database. |
| SSL Mode | Learn more about [SSL mode](/int/mysql-import-integration-cli) |
| useLegacyDatetimeCode | Learn more about [useLegacyDatetimeCode](https://docs.treasuredata.com/smart/project-product-documentation/backward-incompatibility-required-setting-change-for-the-mysql-data-connector-2018) |
| OPTIONS |  |
| **JDBC Connection options** | Any special JDBC connections required by remote database. |
| **Socket connection timeout** | Timeout (in seconds) for socket connection (default is 300). |
| **Network timeout** | Timeout (in seconds) for network socket operations. 0 means no timeout. |


### Name Your Connection

1. Type a name for your connection.
2. Select **Done.**


### Transfer Your MySQL Account Data to Treasure Data

After creating the authenticated connection, you are automatically taken to Authentications.

1. Search for the connection you created.
2. Select **New Source**.


### **Connection**

1. Type a name for your **Source** in the Data Transfer field**.**

### Source Table

Provide the details of the database and table you would like to ingest data from.

1. Select **Next**
2. Edit the following parameters.


| **Parameters** | **Description** |
|  --- | --- |
| **Database name** | The name of the database you are transferring data from. (Ex. `your_database_name`) |
| **Use custom SELECT query?** | Use if you need more than a simple SELECT (columns) FROM table WHERE (condition). |
| **SELECT columns** | If there are only specific columns you would like to pull data from, list them here. Otherwise all columns will be transferred. |
| **Table** | The table from which you would like to import the data. |
| **WHERE condition** | If you need additional specificity on the data retrieved from the table you can specify it here as you would as part of `WHERE` clause. |


### Data Settings

1. Select **Next**.
The Data Settings page opens.
2. Optionally, edit the data settings or skip this page of the dialog.

| **Parameters** | **Description** |
|  --- | --- |
| **Incremental** | In cases where you repeatedly run this transfer, this checkbox will allow you to only import data since the last time the import was run. |
| **Rows per batch** | Extremely large datasets can lead to memory issues and subsequently failed jobs. This flag allows you to breakdown the import job into batches by a number of rows to reduce the chances of memory issues and failed jobs. |
| **Default timezone** | The timezone to be used when doing the import. Default is `UTC` however, you can change this if needed. |
| **After SELECT** | This SQL will be executed after the SELECT query in the same transaction. |
| **Column Options** | If you need to modify the type of column before importing it, select this option and the relevant column details. Select `Save` to save any advanced setting you have entered. |


### Data Preview

You can see a [preview](/products/customer-data-platform/integration-hub/batch/import/previewing-your-source-data) of your data before running the import by selecting Generate Preview. Data preview is optional and you can safely skip to the next page of the dialog if you choose to.

1. Select **Next**. The Data Preview page opens.
2. If you want to preview your data, select **Generate Preview**.
3. Verify the data.


### Data Placement

For data placement, select the target database and table where you want your data placed and indicate how often the import should run.

1. Select **Next.** Under Storage, you will create a new or select an existing database and create a new or select an existing table for where you want to place the imported data.
2. Select a **Database** > **Select an existing** or **Create New Database**.
3. Optionally, type a database name.
4. Select a **Table**> **Select an existing** or **Create New Table**.
5. Optionally, type a table name.
6. Choose the method for importing the data.
  - **Append** (default)-Data import results are appended to the table.
If the table does not exist, it will be created.
  - **Always Replace**-Replaces the entire content of an existing table with the result output of the query. If the table does not exist, a new table is created.
  - **Replace on New Data**-Only replace the entire content of an existing table with the result output when there is new data.
7. Select the **Timestamp-based Partition Key** column.
If you want to set a different partition key seed than the default key, you can specify the long or timestamp column as the partitioning time. As a default time column, it uses upload_time with the add_time filter.
8. Select the **Timezone** for your data storage.
9. Under **Schedule**, you can choose when and how often you want to run this query.


#### Run once

1. Select **Off**.
2. Select **Scheduling Timezone**.
3. Select **Create & Run Now**.


#### Repeat Regularly

1. Select **On**.
2. Select the **Schedule**. The UI provides these four options: *@hourly*, *@daily* and *@monthly* or custom *cron*.
3. You can also select **Delay Transfer** and add a delay of execution time.
4. Select **Scheduling Timezone**.
5. Select **Create & Run Now**.


After your transfer has run, you can see the results of your transfer in **Data Workbench** > **Databases.**
