> Key: FLINK-19038
> URL: https://issues.apache.org/jira/browse/FLINK-19038
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / API
> Affects Versions: 2.1.0
> Reporter: Dian Fu
> Priority: Major
> Labels: auto-unassigned, pull-request-available
> Fix For: 2.1.0
>
>
> For example, table.limit(3).limit(2) will failed with "FETCH is already
> defined."
> {code}
> org.apache.flink.table.api.ValidationException: FETCH is already defined.
> at
> org.apache.flink.table.operations.utils.SortOperationFactory.validateAndGetChildSort(SortOperationFactory.java:125)
> at
> org.apache.flink.table.operations.utils.SortOperationFactory.createLimitWithFetch(SortOperationFactory.java:105)
> at
> org.apache.flink.table.operations.utils.OperationTreeBuilder.limitWithFetch(OperationTreeBuilder.java:418)
> {code}
> However, as we support to call table.limit() without specifying the order, I
> guess this should be a valid usage and should be allowed.
