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 Email, Username FROM NorthwindOData WHERE Email = ?", "[email protected]")
defer rows.Close()
for rows.Next() {
        var (
                Email string
                Username string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT Email, Username FROM NorthwindOData WHERE Email = ?")
defer stmt.Close()

rows, _ := stmt.Query("[email protected] 1")
defer rows.Close()
for rows.Next() {
        var (
                Email string
                Username string
        )

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

rows, _ = stmt.Query("[email protected] 2")
defer rows.Close()
for rows.Next() {
        var (
                Email string
                Username string
        )

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