 JSQLParser interprets Squared Brackets ``[..]`` as Arrays, which does not work with MS SQL Server and T-SQL. Please use the Parser Features to instruct JSQLParser to read Squared Brackets as Quotes instead.
 
-JSQLParser allows for standard compliant Single Quote ``'..`` Escaping. Additional Back-slash ``\..`` Escaping needs to be activated by setting the ``BackSlashEscapeCharacter`` parser feature. JSQLParser reads Double Quotes ``".."`` as quoted identifiers (ANSI SQL); reading them as String Literals (BigQuery, Spark/Databricks, MySQL default sql_mode) needs the ``DoubleQuotedStrings`` parser feature.

-Instead of turning the individual Parser Features on one by one, a ``Dialect`` preset selects the features of that database dialect: ``withDialect(Dialect.MYSQL)`` turns on ``withBackslashEscapeCharacter``, ``withHashLineComments`` and ``withDoubleQuotedStrings`` (MySQL and MariaDB syntax, the latter for the default sql_mode), ``withDialect(Dialect.SQLSERVER)`` turns on ``withSquareBracketQuotation``. Features set explicitly after the dialect preset win over the preset.
