Parameterized Statements
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 ShipName, ShipCity FROM \"defaultdb\".\"public\".Orders WHERE ShipCountry = ?", "USA") defer rows.Close() for rows.Next() { var ( ShipName string ShipCity string ) rows.Scan(&ShipName, &ShipCity) fmt.Printf("ShipName = %s, ShipCity = %s\n", ShipName, ShipCity) }
Reusable Statements
The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.
stmt, _ := db.Prepare("SELECT ShipName, ShipCity FROM \"defaultdb\".\"public\".Orders WHERE ShipCountry = ?") defer stmt.Close() rows, _ := stmt.Query("USA 1") defer rows.Close() for rows.Next() { var ( ShipName string ShipCity string ) rows1.Scan(&ShipName, &ShipCity) fmt.Printf("ShipName = %s, ShipCity = %s\n", ShipName, ShipCity) } rows, _ = stmt.Query("USA 2") defer rows.Close() for rows.Next() { var ( ShipName string ShipCity string ) rows2.Scan(&ShipName, &ShipCity) fmt.Printf("ShipName = %s, ShipCity = %s\n", ShipName, ShipCity) }
