    Hi,

    metadata ID is "MYSQL", not "MySQL".

    Thanks for the answer

    Actually I am still getting the same answer even after changing the database type. Below is the code snippet where I am using above statement. Basically what I am trying to do is generate a domain using view sql and then try to generate a mql query using databasemeta object.

    public static Query queryObject;

    public static IMetadataDomainRepository repo = new InMemoryMetadataDomainRepository();

    public static SqlGenerator gen = new SqlGenerator();

    /// Below snippet

    createDomain(query);

    LogicalModel logModel = domain.getLogicalModels().get(0);

    Query query = new Query(domain, logModel);

    repo.storeDomain(domain, false);

    DatabaseMeta meta = new DatabaseMeta("db", "MYSQL", "Native" , "localhost", "db", "3306", "root", "tiger");

    MappedQuery mQuery = gen.generateSql(query, "en_US", repo, meta);
