/*
  How Properties of Mime Types are used by SQL Mode
  =================================================

  keywords:
    A list of keywords you want to be highlighted.
  builtin:
    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
  operatorChars:
    All characters that must be handled as operators.
  client:
    Commands parsed and executed by the client (not the server).
  support:
    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
    * ODBCdotTable: .tableName
    * zerolessFloat: .1
    * doubleQuote
    * nCharCast: N'string'
    * charsetCast: _utf8'string'
    * commentHash: use # char for comments
    * commentSlashSlash: use // for comments
    * commentSpaceRequired: require a space after -- for comments
  atoms:
    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
    UNKNOWN, INFINITY, UNDERFLOW, NaN...
  dateSQL:
    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.
