FlyingZC opened a new issue, #29172: URL: https://github.com/apache/shardingsphere/issues/29172
# Background Hi community. This issue is for #29149. The ShardingSphere SQL parser engine helps users to parse SQL to create the AST (Abstract Syntax Tree) and visit the AST to get SQLStatement (Java Object). Currently, we are planning to enhance the support for `SQL Server` SQL parsing in ShardingSphere. More details: https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/ # Task This issue is to support more `SQL Server` sql parsing, as follows: ```sql INSERT OPENQUERY (MyLinkServer, 'SELECT Name, GroupName FROM AdventureWorks2022.HumanResources.Department') VALUES ('Environmental Impact', 'Engineering') ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/statements/insert-transact-sql?view=sql-server-ver16) ```sql INSERT INTO HumanResources.Department WITH (IGNORE_TRIGGERS) (Name, GroupName) SELECT b.Name, b.GroupName FROM OPENROWSET ( BULK 'C:SQLFilesDepartmentData.txt', FORMATFILE = 'C:SQLFilesBulkloadFormatFile.xml', ROWS_PER_BATCH = 15000)AS b ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/statements/insert-transact-sql?view=sql-server-ver16) ```sql INSERT INTO Production.Location WITH (XLOCK) (Name, CostRate, Availability) VALUES ( N'Final Inventory', 15.00, 80.00) ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/statements/insert-transact-sql?view=sql-server-ver16) ```sql INSERT Production.ScrapReason OUTPUT INSERTED.ScrapReasonID, INSERTED.Name, INSERTED.ModifiedDate INTO @MyTableVar VALUES (N'Operator error', GETDATE()) ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/statements/insert-transact-sql?view=sql-server-ver16) ```sql INSERT INTO Production.ZeroInventory (DeletedProductID, RemovedOnDate) SELECT ProductID, GETDATE() FROM ( MERGE Production.ProductInventory AS pi USING (SELECT ProductID, SUM(OrderQty) FROM Sales.SalesOrderDetail AS sod JOIN Sales.SalesOrderHeader AS soh ON sod.SalesOrderID = soh.SalesOrderID AND soh.OrderDate = '20070401' GROUP BY ProductID) AS src (ProductID, OrderQty) ON (pi.ProductID = src.ProductID) WHEN MATCHED AND pi.Quantity - src.OrderQty <= 0 THEN DELETE WHEN MATCHED THEN UPDATE SET pi.Quantity = pi.Quantity - src.OrderQty OUTPUT $action, deleted.ProductID) AS Changes (Action, ProductID) WHERE Action = 'DELETE' ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/statements/insert-transact-sql?view=sql-server-ver16) # Process 1. First confirm that this is a correct `SQL Server` sql syntax, if not please leave a message under the issue and ignore it; 2. Compare SQL definitions in Official SQL Doc and ShardingSphere SQL Doc; 3. If there is any difference in ShardingSphere SQL Doc, please correct them by referring to the Official SQL Doc; 4. Run mvn install the current_file_module; 5. Check whether there are any exceptions. If indeed, please fix them. (Especially xxxVisitor.class); 6. Add new corresponding SQL case in SQL Cases and expected parsed result in Expected Statement XML; 7. Run SQLParserParameterizedTest to make sure no exceptions. # Relevant Skills 1. Master JAVA language 2. Have a basic understanding of Antlr `g4` file 3. Be familiar with `SQL Server` SQLs -- This is an automated message from the Apache Git Service.
