gudusoft.gsqlparser.sqlcmds.TSqlCmdsOceanbaseOracle

All Implemented Interfaces:

ISqlCmds

public class TSqlCmdsOceanbaseOracle
extends TSqlCmdsOracle

OceanBase Oracle-mode SQL command resolver — Phase 4 Batch 6+.

Extends the stock TSqlCmdsOracle to add recognition for OceanBase-specific DDL that parses through the Oracle-mode fork: currently the CREATE/ALTER/DROP TABLEGROUP family (Batch 6).

This class keeps OceanBase-specific prefix registrations out of the shared TSqlCmdsOracle so base-Oracle semantics remain unchanged and backportable. OceanBaseOracleSqlParser selects this subclass in its constructor.

Since:

4.0.1.4

Method Detail

initializeCommands

protected void initializeCommands()

Description copied from class: AbstractSqlCmds

Initialize vendor-specific commands. Subclasses must implement this to populate sqlCmdList.

Overrides:

initializeCommands in class TSqlCmdsOracle

issql

public TCustomSqlStatement issql(TSourceToken token,
                                 EFindSqlStateType state,
                                 TCustomSqlStatement currentStatement)

Intercept the TUnknownSqlStatement produced by TSqlCmdsOracle.issql(gudusoft.gsqlparser.TSourceToken, gudusoft.gsqlparser.EFindSqlStateType, gudusoft.gsqlparser.TCustomSqlStatement) for the OceanBase tablegroup types and swap in the proper statement class so downstream tools switch on the real type rather than the opaque unknown shell.

Specified by:

issql in interface ISqlCmds

Overrides:

issql in class TSqlCmdsOracle

Parameters:

token - Current token being analyzed

state - Current parsing state (start, in body, or in exception)

currentStatement - Current statement being built (may be modified)

Returns:

The identified or modified SQL statement
