Julian Hyde updated CALCITE-1952:
---------------------------------
Description:
Using Apache Calcite on Windows and trying to query the DEPTS.csv used on the
website tutorial I get a NullPointerException when using Calcite Core 1.13.0
but when I use 1.12.0 the issue disappears.
{code}
Properties info = new Properties();
info.put("model", "../src/test/resources/files.json");
info.setProperty("lex", "JAVA");
Connection connection = DriverManager.getConnection("jdbc:calcite:", info);
Statement stmt = connection.createStatement();
String sql = "select * from FILES.DEPTS";
ResultSet rs = stmt.executeQuery(sql);
while(rs.next()) {
System.out.println(rs.getString(1));
}
{code}
And the exception is as follows:-
{noformat}
java.sql.SQLException: Error while executing SQL "select * from FILES.DEPTS":
