Julian Hyde updated CALCITE-6016:
---------------------------------
    Description: 
Might be similar to : DRILL-7415

I am connected to Snowflake datasource using calcite connection and I am trying 
to execute SQL using a statement.

I have only single table in database.

 

My code :
{code:java}
public static boolean getSnowflakeConnection() throws SQLException {
    String modelPath = "/Users/A200118159/Documents/Code/TestSpringBoot 
2/src/main/resources/models/snowflake_model.json"; 
//"/Users/A200118159/test/snowflake_model.json";
    Properties properties = new Properties();
    properties.setProperty("model", modelPath);
    properties.setProperty("caseSensitive", "false");

// Create a Calcite connection
    Connection connection = DriverManager.getConnection("jdbc:calcite:", 
properties);
    CalciteConnection calciteConnection = 
connection.unwrap(CalciteConnection.class);


    Statement statement = calciteConnection.createStatement();
    ResultSet resultSet = statement.executeQuery("SELECT * FROM PRODUCTS");

    printTable(resultSet);
    calciteConnection.close();
    return true;
  } {code}
Snowflake Model File:
{code:java}
{
  "version": "1.0",
  "defaultSchema": "Snowflake",
  "schemas": [
    {
      "name": "Snowflake",
      "type": "custom",
      "factory": "org.apache.calcite.adapter.jdbc.JdbcSchema$Factory",
      "operand": {
        "jdbcUser": "argus",
        "jdbcPassword": "Argus123",
        "jdbcUrl": 
"jdbc:snowflake://er14275.ap-southeast-1.snowflakecomputing.com/?warehouse=COMPUTE_WH&db=ARGUS_DATA&schema=ARGUS_SCHEMA",
        "jdbcDriver": "net.snowflake.client.jdbc.SnowflakeDriver"
      }
    }
  ]
} {code}
But I am getting below error:
