    • createForVendor

      public static TSQLResolverConfig createForVendor(EDbVendor vendor)
      Create configuration for a specific database vendor.

      This factory method creates a configuration with vendor-specific name matching rules. The VendorNameMatcher uses IdentifierService to properly handle case sensitivity and quote handling for each vendor.

      Example vendor behaviors:

      • Oracle: Unquoted identifiers fold to UPPER, quoted are case-sensitive
      • PostgreSQL: Unquoted identifiers fold to LOWER, quoted are case-sensitive
      • MySQL: Depends on lower_case_table_names setting
      • BigQuery: Table names are case-sensitive, column names are case-insensitive
      Parameters:
      vendor - the database vendor
      Returns:
      configuration with vendor-specific name matcher

    • createForVendorWithDatatype

      public static TSQLResolverConfig createForVendorWithDatatype(EDbVendor vendor)
