FlyingZC opened a new issue, #29183: URL: https://github.com/apache/shardingsphere/issues/29183
# 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 UPDATE Production.Product SET Color = N'Metallic Red' WHERE Name LIKE N'Road-250%' AND Color = N'Red' ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/queries/update-transact-sql?view=sql-server-ver16) ```sql UPDATE HumanResources.EmployeePayHistory SET PayFrequency = 2 WHERE CURRENT OF complex_cursor ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/queries/update-transact-sql?view=sql-server-ver16) ```sql UPDATE Production.Product SET ListPrice += @NewPrice WHERE Color = N'Red' ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/queries/update-transact-sql?view=sql-server-ver16) ```sql UPDATE Production.ScrapReason SET Name += ' - tool malfunction' WHERE ScrapReasonID BETWEEN 10 and 12 ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/queries/update-transact-sql?view=sql-server-ver16) ```sql UPDATE sr SET sr.Name += ' - tool malfunction' FROM Production.ScrapReason AS sr JOIN Production.WorkOrder AS wo ON sr.ScrapReasonID = wo.ScrapReasonID AND wo.ScrappedQty > 300 ``` [link](https://learn.microsoft.com/zh-cn/sql/t-sql/queries/update-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.
