Executes an SQL SELECT query to get the data from the underlying snowflake database.
* When constructing the SQL SELECT query make sure to use the fully qualified table names
  that include the database name, schema name and the table name.
* The fully qualified table name can be found in the table information, use a tool to get the information
  about tables. The fully qualified table name can be found in the response for that tool.
* Snowflake is case-sensitive so always wrap the column names in double quotes.

Examples:
* SQL queries must include the fully qualified table names including the database name, e.g.:
  SELECT * FROM "db_name"."db_schema_name"."table_name";
