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:

INSERT INTO ContosoWarehouse.dbo.Affiliation
SELECT * 
FROM My_Lakehouse.dbo.Affiliation

SELECT c.name AS column_name  
    ,c.column_id  
    ,SCHEMA_NAME(t.schema_id) AS type_schema  
    ,t.name AS type_name  
    ,t.is_user_defined  
    ,t.is_assembly_type  
    ,c.max_length  
    ,c.precision  
    ,c.scale  
FROM sys.columns AS c   
JOIN sys.types AS t ON c.user_type_id=t.user_type_id  
WHERE c.object_id = OBJECT_ID('<schema_name.table_name>')  
ORDER BY c.column_id

SELECT OBJECT_NAME(object_id) AS referencing_object_name  
    ,COALESCE(COL_NAME(object_id, column_id), '(n/a)') AS referencing_column_name  
    ,*  
FROM sys.sql_dependencies  
WHERE referenced_major_id = OBJECT_ID('<schema_name.function_name>')  
ORDER BY OBJECT_NAME(object_id), COL_NAME(object_id, column_id)

link

SELECT SCHEMA_NAME(schema_id) AS schema_name  
    ,o.name AS object_name  
    ,o.type_desc  
    ,p.parameter_id  
    ,p.name AS parameter_name  
    ,TYPE_NAME(p.user_type_id) AS parameter_type  
    ,p.max_length  
    ,p.precision  
    ,p.scale  
    ,p.is_output  
FROM sys.objects AS o  
INNER JOIN sys.parameters AS p ON o.object_id = p.object_id  
WHERE o.object_id = OBJECT_ID('<schema_name.object_name>')  
ORDER BY schema_name, object_name, p.parameter_id

link

SELECT name AS view_name   
  ,SCHEMA_NAME(schema_id) AS schema_name  
  ,OBJECTPROPERTYEX(object_id,'IsIndexed') AS IsIndexed  
  ,OBJECTPROPERTYEX(object_id,'IsIndexable') AS IsIndexable  
  ,create_date  
  ,modify_date  
FROM sys.views

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
