@tristaZero @guimingyue Look at the example below `https://github.com/zabetak/calcite/blob/c7646fa6d3054b9e6b9a800e08d18f3cc89922e4/core/src/test/java/org/apache/calcite/examples/foodmart/java/EndToEndExampleEnumerable.java` on line 127 ,you can replace the sql parser on line 156 ,can replace RelNode with RelBuilder on line 165-179,it is optimizer code. after 187 ,the plan runs. so you need a converter that builds RelNode from ShardingSphere Parser or convert ShardingSphere AST to RelNode or ShardingSphere AST to org.apache.calcite.sql.SqlNode. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
