Query Percona	Percona	Use [`sql.from()`](/flux/v0.x/stdlib/sql/from/) with the `mysql` driver to query Percona.	flux_0_x name parent Percona SQL databases	101	/flux/v0.x/stdlib/sql/from/	```js import "sql" sql.from( driverName: "mysql", dataSourceName: "user:password@tcp(localhost:3306)/db", query: "SELECT * FROM example_table", ) ```

To query Percona with Flux:

1. Import the sql package.

2. Use sql.from() and provide the following parameters:

   • driverName: mysql
   • dataSourceName: See data source name
   • query: SQL query to execute

import "sql"

sql.from(
    driverName: "mysql",
    dataSourceName: "user:password@tcp(localhost:3306)/db",
    query: "SELECT * FROM example_table",
)

Percona data source name

The mysql driver uses the following data source name (DSN) syntax (also known as a connection string):

username:password@tcp(localhost:3306)/dbname?param=value

Percona to Flux data type conversion

sql.from() converts Percona data types to Flux data types.

Percona data type	Flux data type
INT, BIGINT, SMALLINT, TINYINT	int
FLOAT, DOUBLE	float
DATETIME	time
STRING	string

{{% caption %}} All other Percona data types are converted to strings. {{% /caption %}}
