Query Percona

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 typeFlux data type
INT, BIGINT, SMALLINT, TINYINTint
FLOAT, DOUBLEfloat

All other Percona data types are converted to strings.
