ShardingSphere supports multiple dialects of SQL using different parsers. For specific SQL dialects that do not implement parsers, the default is to use the SQL92 standard for parsing.
Note: MySQL parser supports MySQL, H2, and MariDB dialect.
Other SQL dialects, such as SQLite, Sybase, DB2 and Informix, are parsed by default using the standard of SQL92.
This is a particular parser for ShardingSphere, which mainly to parse the RDL, namely ShardingSphere-defined SQL. RDL will show you more.
