我如何從Scala連接到Exasol？

Question

我想使用Scala連接到ExaSol數據庫。 我可以使用pyodbc在Python中連接到數據庫，但在Scala中嘗試使用JDBC驅動程序進行連接時收到以下錯誤：

scala> :require /Users/some/path/mssql-jdbc-7.4.0.jre8.jar
scala> Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver")
scala> import java.sql.{Connection, DriverManager, ResultSet}
scala> val conn = DriverManager.getConnection("jdbc:sqlserver://11.11.11.11:8563;databaseName=some-db;user=user_name;password=pass_word;useUnicode=true;characterEncoding=UTF-8")

請嘗試使用“ com.exasol.jdbc.EXADriver”驅動程序。
