The following code example shows how to bind parameters to create parameterized statements.

Single-Use Statements

The Query and Exec functions both accept additional parameters for binding query parameters to values.

rows, _ := db.Query("SELECT Clicks, Device FROM CampaignPerformance WHERE Device = ?", "Mobile devices with full browsers")
defer rows.Close()
for rows.Next() {
        var (
                Clicks string
                Device string
        )

        rows.Scan(&Clicks, &Device)
        fmt.Printf("Clicks = %s, Device = %s\n", Clicks, Device)
}

Reusable Statements

The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.

stmt, _ := db.Prepare("SELECT Clicks, Device FROM CampaignPerformance WHERE Device = ?")
defer stmt.Close()

rows, _ := stmt.Query("Mobile devices with full browsers 1")
defer rows.Close()
for rows.Next() {
        var (
                Clicks string
                Device string
        )

        rows1.Scan(&Clicks, &Device)
        fmt.Printf("Clicks = %s, Device = %s\n", Clicks, Device)
}

rows, _ = stmt.Query("Mobile devices with full browsers 2")
defer rows.Close()
for rows.Next() {
        var (
                Clicks string
                Device string
        )

        rows2.Scan(&Clicks, &Device)
        fmt.Printf("Clicks = %s, Device = %s\n", Clicks, Device)
}
