How to use the Connector object
A Connector holds information in a DSN and is ready to make a new connection at any time. Connector implements the database/sql/driver Connector interface so it can be passed to the database/sql OpenDB function. One property on the Connector is the SessionInitSQL field, which may be used to set any options that cannot be passed through a DSN string.
To use the Connector type, first you need to import the sql and go-mssqldb packages
import (
"database/sql"
"github.com/denisenkom/go-mssqldb"
)
Now you can create a Connector object by calling NewConnector, which creates a new connector from a DSN.
dsn := "sqlserver://username:password@hostname/instance?database=databasename"
connector, err := mssql.NewConnector(dsn)
You can set connector.SessionInitSQL for any options that cannot be passed through in the dsn string.
connector.SessionInitSQL = "SET ANSI_NULLS ON"
Open a database by passing connector to sql.OpenDB.
db := sql.OpenDB(connector)
The returned DB maintains its own pool of idle connections. Now you can use the sql.DB object for querying and executing queries.
