    Remember the following tips when querying data with Drill:

    • Include a semicolon at the end of SQL statements, except when you issue a [COLOR=#1a6bc7]Drill shell command[/COLOR].
      Example:!set maxwidth 10000`
    • Use backticks around [COLOR=#1a6bc7]keywords[/COLOR], special characters, and [COLOR=#1a6bc7]identifiers[/COLOR] that SQL cannot parse, such as the keyword default and a path that contains a forward slash character: Example: SELECT * FROM dfs.`default`.`/Users/drilluser/apache-drill-1.1.0/sample-data/nation.parquet`;
    • When selecting all (SELECT *) schema-less data, the order of returned columns might differ from the stored order and might vary from query to query.
