Support parsing SQL Server SELECT ProductId, sql #29159

Closed FlyingZC closed 7 months ago

FlyingZC commented 10 months ago

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:

SELECT ProductId, Name, Tags
FROM Product
WHERE EXISTS (SELECT *
    FROM STRING_SPLIT(Tags, ',')
    WHERE value IN ('clothing', 'road'))

SELECT BusinessEntityID
    , DATEPART(QUARTER, QuotaDate) AS Quarter
    , YEAR(QuotaDate) AS SalesYear
    , SalesQuota AS QuotaThisQuarter
    , SalesQuota - FIRST_VALUE(SalesQuota)
          OVER (PARTITION BY BusinessEntityID, YEAR(QuotaDate)
              ORDER BY DATEPART(QUARTER, QuotaDate)) AS DifferenceFromFirstQuarter
    , SalesQuota - LAST_VALUE(SalesQuota)
          OVER (PARTITION BY BusinessEntityID, YEAR(QuotaDate)
              ORDER BY DATEPART(QUARTER, QuotaDate)
              RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) AS DifferenceFromLastQuarter
FROM Sales.SalesPersonQuotaHistory
WHERE YEAR(QuotaDate) > 2005 AND BusinessEntityID BETWEEN 274 AND 275
ORDER BY BusinessEntityID, SalesYear, Quarter

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
