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 From_User_Name, Text FROM Tweets WHERE From_User_Name = ?", "twitter")
defer rows.Close()
for rows.Next() {
        var (
                From_User_Name string
                Text string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT From_User_Name, Text FROM Tweets WHERE From_User_Name = ?")
defer stmt.Close()

rows, _ := stmt.Query("twitter 1")
defer rows.Close()
for rows.Next() {
        var (
                From_User_Name string
                Text string
        )

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

rows, _ = stmt.Query("twitter 2")
defer rows.Close()
for rows.Next() {
        var (
                From_User_Name string
                Text string
        )

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