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, CloseDate FROM Dataset_Opportunity WHERE StageName = ?", "Closed Won")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                CloseDate string
        )

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

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, CloseDate FROM Dataset_Opportunity WHERE StageName = ?")
defer stmt.Close()

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

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

rows, _ = stmt.Query("Closed Won 2")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                CloseDate string
        )

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