## Bug Report ### Which version of ShardingSphere did you use? https://github.com/apache/shardingsphere/commit/684eaa5d02978b54a3f63c8c3aa286bf4d590234 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-Proxy ### Expected behavior ```sql [ WITH [ RECURSIVE ] with_query [, ...] ] SELECT [/*+ plan_hint */] [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ] { * | {expression [ [ AS ] output_name ]} [, ...] } [ FROM from_item [, ...] ] [ WHERE condition ] [ [ START WITH condition ] CONNECT BY [NOCYCLE] condition [ ORDER SIBLINGS BY expression ] ] [ GROUP BY grouping_element [, ...] ] [ HAVING condition [, ...] ] [ WINDOW {window_name AS ( window_definition )} [, ...] ] [ { UNION | INTERSECT | EXCEPT | MINUS } [ ALL | DISTINCT ] select ] [ ORDER BY {expression [ [ ASC | DESC | USING operator ] | nlssort_expression_clause ] [ NULLS { FIRST | LAST } ]} [, ...] ] [ LIMIT { [offset,] count | ALL } ] [ OFFSET start [ ROW | ROWS ] ] [ FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY ] [ {FOR { UPDATE | NO KEY UPDATE | SHARE | KEY SHARE } [ OF table_name [, ...] ] [ NOWAIT ]} [...] ]; ``` According to openGauss select limit sytax, this sql should result following result. ```sql sharding_db=> select * from test where aid > 0; aid | aname | bid | bname -----+-------+-----+------- 2 | a | 2 | b 3 | a | 3 | b (2 rows) sharding_db=> select * from test where aid > 0 limit 1, 2; aid | aname | bid | bname -----+-------+-----+------- 3 | a | 3 | b (1 rows) ``` ### Actual behavior It seems that the SQL parsing engine parses count and offset incorrectly. ```sql sharding_db=> select * from test where aid > 0; aid | aname | bid | bname -----+-------+-----+------- 2 | a | 2 | b 3 | a | 3 | b (2 rows) sharding_db=> select * from test where aid > 0 limit 1, 2; aid | aname | bid | bname -----+-------+-----+------- (0 rows) ``` ### Reason analyze (If you can) ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
