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 Name, Owner FROM DataModels WHERE Id = ?", "SampleDataset")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                Owner string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT Name, Owner FROM DataModels WHERE Id = ?")
defer stmt.Close()

rows, _ := stmt.Query("SampleDataset 1")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                Owner string
        )

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

rows, _ = stmt.Query("SampleDataset 2")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                Owner string
        )

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