Impala Translator - add pushdown support for concat and concat_ws functions --------------------------------------------------------------------------- Key: TEIID-4422 URL: https://issues.jboss.org/browse/TEIID-4422 Project: Teiid Issue Type: Feature Request Components: JDBC Connector Affects Versions: 9.0.2 Reporter: Don Krapohl Assignee: Steven Hawkins Fix For: 9.1 As a consumer I need the concat and concat_ws function definitions with matching signatures in line with http://www.cloudera.com/documentation/archive/impala/2-x/2-0-x/topics/imp... concat: concat(string a, string b...) Purpose: Returns a single string representing all the argument values joined together. Return type: string Usage notes: concat() and concat_ws() are appropriate for concatenating the values of multiple columns within the same row, while group_concat() joins together values from different rows. concat_ws: concat_ws(string sep, string a, string b...) Purpose: Returns a single string representing the second and following argument values joined together, delimited by a specified separator. Return type: string Usage notes: concat() and concat_ws() are appropriate for concatenating the values of multiple columns within the same row, while group_concat() joins together values from different rows.
