Multiple PostgreSQL database (same server) access in Slick 2

Question

So I have a Scala/Play application that uses multiple MySQL and PostgreSQL databases (on the same server), however I have a problem with PostgreSQL.

This is the configuration:

db.postgres.driver=org.postgresql.Driver
db.postgres.url="jdbc:postgresql://localhost:5432/"
db.postgres.user=root
db.postgres.password=root

db.mysql.driver="com.mysql.jdbc.Driver"
db.mysql.url="jdbc:mysql://localhost"
db.mysql.user=root
db.mysql.pass=root

This simple method works fine with MySQL:

def test = DB("mysql").withDynSession {
    val rez = sql"""select * from dbName.test""".as[TestRow].list
    println(rez)
}

But exactly the same method with Postgres

def test = DB("postgres").withDynSession {
    val rez = sql"""select * from dbName.test""".as[TestRow].list
    println(rez)
}

throws an error:

org.postgresql.util.PSQLException: ERROR: relation "dbName.test" does not exist

How come these methods are identical, but MySQL example works and PostgreSQL doesn't?

My stack:

• Scala 2.10.3
• Play 2.2.2
• Slick 2.0
• PostgreSQL 9.3.3
• MySQL 5.6.16
• Java 8

Postgresql JDBC driver version is 9.3-1101-jdbc41

Answer 1

This may be a case sensitivity issue. Try quoting the names and adding the schema to the qualified name: sql"""select * from "dbName"."theSchema"."test"""" Does this help?

Answer 2

I had the same problem.

I am using Slick 2.0 with lifted embedding and PostgreSQL 9.3.

You have to set your schema when you define your table:

class Coffees(tag: Tag) extends Table[(String, Int, Double, Int, Int)](tag, Some("MYSCHEMA"), "COFFEES") {
