How could I know if a database table is exists in ScalaQuery

Question

I\'m trying ScalaQuery, it is really amazing. I could defined the database table using Scala class, and query it easily.

But I would like to know, in the following c

Answer 1

ScalaQuery version 0.9.4 includes a number of helpful SQL metadata wrapper classes in the org.scalaquery.meta package, such as MTable:

http://scalaquery.org/doc/api/scalaquery-0.9.4/#org.scalaquery.meta.MTable

In the test code for ScalaQuery, we can see examples of these classes being used. In particular, see org.scalaquery.test.MetaTest.

I wrote this little function to give me a map of all the known tables, keyed by table name.

import org.scalaquery.meta.{MTable}
def makeTableMap(dbsess: Session) : Map[String, MTable] = {
    val tableList = MTable.getTables.list()(dbsess);
    val tableMap = tableList.map{t => (t.name.name, t)}.toMap;
    tableMap;
}

So now, before I create an SQL table, I can check "if (!tableMap.contains(tableName))".
