Hi Andres Angel,
At present, there seems to be no such built-in function, and you need to register a user-defined function to do that. You can look at the following document to see how to do. https://ci.apache.org/projects/flink/flink-docs-master/dev/table/udfs.html#table-functions Best, Haibo At 2019-07-25 06:00:53, "Andres Angel" <ingenieroandresan...@gmail.com> wrote: Hello everyone, Following the current available functions https://ci.apache.org/projects/flink/flink-docs-release-1.8/dev/table/functions.html, how could I split a column string by a caracter? example column content : col =a,b,c query: Select col from tenv expected return : cola , colb, colc thanks
