Xianghu Wang closed HUDI-1946. ------------------------------ Resolution: Not A Problem > Enhance SqlQueryBasedTransformer to allow user use wildcard to represent all > the columns > ---------------------------------------------------------------------------------------- > > Key: HUDI-1946 > URL: https://issues.apache.org/jira/browse/HUDI-1946 > Project: Apache Hudi > Issue Type: New Feature > Reporter: Xianghu Wang > Assignee: Xianghu Wang > Priority: Major > Labels: pull-request-available > Fix For: 0.9.0 > > > When the user wants to derive one or more columns from the existing columns > and the > existing columns are all needed, the user needs to spell all the columns they > need in the SQL. > This will be very troublesome and time-consuming when we have dozens or > hundreds of columns. we can save trouble by using a wildcard in the SQL to > represent all the columns. > that means if we have "id", "name", "age", "ts" these four columns already > and we want to add a new column driver from ts, we can use > "select *, FROM_UNIXTIME(ts / 1000, 'yyyyMMdd') as dt from table_name" > to represent > "select id, name, age, ts, FROM_UNIXTIME(ts / 1000, 'yyyyMMdd') as dt from > table_name" -- This message was sent by Atlassian Jira (v8.3.4#803005)
