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 Username, Email FROM [CData].[Administrators].Users WHERE Id = ?", "39ef9b6f-5973-4701-bd19-7950d4b7d6e0")
defer rows.Close()
for rows.Next() {
        var (
                Username string
                Email string
        )

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

Reusable Statements

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

stmt, _ := db.Prepare("SELECT Username, Email FROM [CData].[Administrators].Users WHERE Id = ?")
defer stmt.Close()

rows, _ := stmt.Query("39ef9b6f-5973-4701-bd19-7950d4b7d6e0 1")
defer rows.Close()
for rows.Next() {
        var (
                Username string
                Email string
        )

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

rows, _ = stmt.Query("39ef9b6f-5973-4701-bd19-7950d4b7d6e0 2")
defer rows.Close()
for rows.Next() {
        var (
                Username string
                Email string
        )

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