[GitHub] [shardingsphere] FlyingZC opened a new issue, #27028: Support parsing Oracle CREATE INDEXTYPE sql
FlyingZC opened a new issue, #27028:
URL: https://github.com/apache/shardingsphere/issues/27028
# Background
Hi community,
This issue is for #26878.
ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract Syntax Tree) and visit this tree to get SQLStatement (Java Object). Currently, we are planning to enhance the support for Oracle SQL parsing in ShardingSphere.
More details:
https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/
# Task
This issue is to support more oracle sql parse, as follows:
```sql
CREATE INDEXTYPE TextIndexType
FOR Contains (VARCHAR2, VARCHAR2)
USING TextIndexMethods
WITH LOCAL PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
```
```sql
CREATE INDEXTYPE position_indextype
FOR position_between(NUMBER, NUMBER, NUMBER)
USING position_im;
```
```sql
CREATE JAVA CLASS USING BFILE (java_dir, 'Agent.class')
```
```sql
CREATE JAVA CLASS USING BFILE (Bfile_dir, 'Agent.class');
```
```sql
CREATE JAVA RESOURCE NAMED "appText"
USING BFILE (java_dir, 'textBundle.dat')
```
# Process
1. First confirm that this is a correct oracle sql syntax, if not please ignore;
2. Compare SQL definitions in Oficial 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 Statment 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 Oracle SQLs

Hi @FlyingZC, thanks for raising this. Oracle `CREATE INDEXTYPE` parsing is now supported, so this issue can be closed as completed.
`CREATE INDEXTYPE` support was merged in #39302, including the `createIndexType` grammar rule, the `OracleCreateIndexTypeStatement` AST node, visitor support, and parser test cases covering the examples in this issue (`WITH LOCAL PARTITION` and `WITH SYSTEM MANAGED STORAGE TABLES` variants). The `CREATE JAVA ... USING BFILE` statements listed here were already covered by #28652.
Closing as completed. Feel free to reopen with a concrete SQL example if anything is still unparsed on the latest master.
