Need example of use of PreparedStatement with Anorm scala

Question

I am using Anorm for querying a MySQL database from Playframework 2.1. I created a prepared statement like this.

import play.api.db.DB
import anorm._

val stat = DB.withConnection(implicit c => SQL("SELECT name, email FROM user WHERE id=?").filledStatement)

Now how do I use it? Am I event doing this right? I am totally ignorant of the anorm API and I already went through the source code without gaining much insight.

Code examples are more that welcome.

Answer 1

A good example on the Anorm usage is given in the respective tutorial . It also contains some examples that pass dynamic parameters to the queries. You should start by writing your query and replace declare placeholders like {somePlaceholder} in the query string. You can later assign values using the .on() method like this:

SQL(
  """
    select * from Country c 
    join CountryLanguage l on l.CountryCode = c.Code 
    where c.code = {countryCode};
  """
).on("countryCode" -> "FRA")

Or in your case:

import play.api.db.DB
import anorm._

val stat = DB.withConnection(implicit c =>
  SQL("SELECT name, email FROM user WHERE id={id}").on("id" -> 42)
)
