# JDBC

> JDBC sink connector

### Description[​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#description) <a href="#description" id="description"></a>

Write data through jdbc. Support Batch mode and Streaming mode, support concurrent writing, support exactly-once semantics (using XA transaction guarantee).

### Key Features[​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#key-features) <a href="#key-features" id="key-features"></a>

* [x] &#x20;exactly-once

Use `Xa transactions` to ensure `exactly-once`. So only support `exactly-once` for the database which is support `Xa transactions`. You can set `is_exactly_once=true` to enable it.

* [x] &#x20;cdc
* [x] &#x20;support multiple table write

#### table \[string][​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#table-string) <a href="#table-string" id="table-string"></a>

Use `database` and this `table-name` auto-generate sql and receive upstream input datas write to database.

This option is mutually exclusive with `query` and has a higher priority.

The table parameter can fill in the name of an unwilling table, which will eventually be used as the table name of the creation table, and supports variables (`${table_name}`, `${schema_name}`). Replacement rules: `${schema_name}` will replace the SCHEMA name passed to the target side, and `${table_name}` will replace the name of the table passed to the table at the target side.

mysql sink for example:

1. tes&#x74;*${schema\_name}*${table\_name}\_test
2. sink\_sinktable
3. ss\_${table\_name}

pgsql (Oracle Sqlserver ...) Sink for example:

1. ${schema\_name}.${table\_name} \_test

#### field\_ide \[String][​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#field_ide-string) <a href="#field_ide-string" id="field_ide-string"></a>

The field "field\_ide" is used to identify whether the field needs to be converted to uppercase or lowercase when synchronizing from the source to the sink. "ORIGINAL" indicates no conversion is needed, "UPPERCASE" indicates conversion to uppercase, and "LOWERCASE" indicates conversion to lowercase.

#### properties[​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#properties) <a href="#properties" id="properties"></a>

Before the synchronous task is turned on, different treatment schemes are selected for the existing surface structure of the target side.\
Option introduction：\
`RECREATE_SCHEMA` ：Will create when the table does not exist, delete and rebuild when the table is saved\
`CREATE_SCHEMA_WHEN_NOT_EXIST` ：Will Created when the table does not exist, skipped when the table is saved\

Before the synchronous task is turned on, different processing schemes are selected for data existing data on the target side.\
Option introduction：\
`DROP_DATA`： Preserve database structure and delete data\
`APPEND_DATA`：Preserve database structure, preserve data\
`CUSTOM_PROCESSING`：User defined processing\
`ERROR_WHEN_DATA_EXISTS`：When there is data, an error is reported

#### custom\_sql \[String][​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#custom_sql-string) <a href="#custom_sql-string" id="custom_sql-string"></a>

When data\_save\_mode selects CUSTOM\_PROCESSING, you should fill in the CUSTOM\_SQL parameter. This parameter usually fills in a SQL that can be executed. SQL will be executed before synchronization tasks.

#### enable\_upsert \[boolean][​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#enable_upsert-boolean) <a href="#enable_upsert-boolean" id="enable_upsert-boolean"></a>

Enable upsert by primary\_keys exist, If the task has no key duplicate data, setting this parameter to `false` can speed up data import

#### use\_copy\_statement \[boolean][​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#use_copy_statement-boolean) <a href="#use_copy_statement-boolean" id="use_copy_statement-boolean"></a>

Use `COPY ${table} FROM STDIN` statement to import data. Only drivers with `getCopyAPI()` method connections are supported. e.g.: Postgresql driver `org.postgresql.Driver`.

NOTICE: `MAP`, `ARRAY`, `ROW` types are not supported.

#### create\_index \[boolean][​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#create_index-boolean) <a href="#create_index-boolean" id="create_index-boolean"></a>

Create the index(contains primary key and any other indexes) or not when auto-create table. You can use this option to improve the performance of jdbc writes when migrating large tables.

Notice: Note that this will sacrifice read performance, so you'll need to manually create indexes after the table migration to improve read performance

### tips[​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#tips) <a href="#tips" id="tips"></a>

In the case of is\_exactly\_once = "true", Xa transactions are used. This requires database support, and some databases require some setup : 1 postgres needs to set `max_prepared_transactions > 1` such as `ALTER SYSTEM set max_prepared_transactions to 10`. 2 mysql version need >= `8.0.29` and Non-root users need to grant `XA_RECOVER_ADMIN` permissions. such as `grant XA_RECOVER_ADMIN on test_db.* to 'user1'@'%'`. 3 mysql can try to add `rewriteBatchedStatements=true` parameter in url for better performance.

### Example[​](https://seatunnel.apache.org/docs/2.3.7/connector-v2/sink/Jdbc#example) <a href="#example" id="example"></a>

Simple

```
jdbc {
    url = "jdbc:mysql://localhost:3306/test"
    driver = "com.mysql.cj.jdbc.Driver"
    user = "root"
    password = "123456"
    query = "insert into test_table(name,age) values(?,?)"
}

```

Exactly-once

Turn on exact one-time semantics by setting `is_exactly_once`

```
jdbc {

    url = "jdbc:mysql://localhost:3306/test"
    driver = "com.mysql.cj.jdbc.Driver"

    max_retries = 0
    user = "root"
    password = "123456"
    query = "insert into test_table(name,age) values(?,?)"

    is_exactly_once = "true"

    xa_data_source_class_name = "com.mysql.cj.jdbc.MysqlXADataSource"
}
```

CDC(Change data capture) event

jdbc receive CDC example

```
sink {
    jdbc {
        url = "jdbc:mysql://localhost:3306"
        driver = "com.mysql.cj.jdbc.Driver"
        user = "root"
        password = "123456"
        
        database = "sink_database"
        table = "sink_table"
        primary_keys = ["key1", "key2", ...]
    }
}
```

Add saveMode function

To facilitate the creation of tables when they do not already exist, set the `schema_save_mode` to `CREATE_SCHEMA_WHEN_NOT_EXIST`.

```
sink {
    jdbc {
        url = "jdbc:mysql://localhost:3306"
        driver = "com.mysql.cj.jdbc.Driver"
        user = "root"
        password = "123456"
        generate_sink_sql = "true"
        database = "sink_database"
        table = "sink_table"
        primary_keys = ["key1", "key2", ...]
        schema_save_mode = "CREATE_SCHEMA_WHEN_NOT_EXIST"
        data_save_mode="APPEND_DATA"
    }
}
```

Postgresql 9.5 version below support CDC(Change data capture) event

For PostgreSQL versions 9.5 and below, setting `compatible_mode` to `postgresLow` to enable support for PostgreSQL Change Data Capture (CDC) operations.

```
sink {
    jdbc {
        url = "jdbc:postgresql://localhost:5432"
        driver = "org.postgresql.Driver"
        user = "root"
        password = "123456"
        compatible_mode="postgresLow"
        database = "sink_database"
        table = "sink_table"
        support_upsert_by_query_primary_key_exist = true
        generate_sink_sql = true
        primary_keys = ["key1", "key2", ...]
    }
}

```
