Subject [GitHub] [incubator-doris] EmmyMiao87 opened a new pull request #3812: Forbidden float column in short key
Date Tue, 09 Jun 2020 16:11:33 GMT

EmmyMiao87 opened a new pull request #3812:
URL: https://github.com/apache/incubator-doris/pull/3812


   When the user does not specify the key column, doris will automatically supplement the
key column.
   However, doris does not support float or double as the key column, so when adding the key
column, doris should avoid setting those column as the key column.
   
   The CreateMaterailizedView, AddRollup and CreateDuplicateTable need to forbidden float
column in short key.
   If the float column is directly encountered during the supplement process, the subsequent
columns are all value columns.
   If the first column is float or double, Doris will throw the exception.
   
   Fixed #3811
