    388            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    389            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    390
    391                spark-sql (default)> select cast(1234 as varchar(2));
    392                23/06/06 15:51:18 WARN CharVarcharUtils: The Spark cast operator does not support
    393                char/varchar type and simply treats them as string type. Please use string type
    394                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    395                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier

    399
    400            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    401            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

    389            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    390            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    391
    392                spark-sql (default)> select cast(1234 as varchar(2));
    393                23/06/06 15:51:18 WARN CharVarcharUtils: The Spark cast operator does not support
    394                char/varchar type and simply treats them as string type. Please use string type
    395                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    396                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier

    400
    401            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    402            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

    389            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    390            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    391
    392                spark-sql (default)> select cast(1234 as varchar(2));

    394                char/varchar type and simply treats them as string type. Please use string type
    395                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    396                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier

    402            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

Parser consumes a list of tokens produced by the Tokenizer and produces a parsed syntax tree.

###### Arguments:

- error_level: The desired error level. Default: ErrorLevel.IMMEDIATE
- error_message_context: The amount of context to capture from a query string when displaying the error message (in number of characters). Default: 100
- max_errors: Maximum number of error messages to include in a raised ParseError. This is only relevant if error_level is ErrorLevel.RAISE. Default: 3

Generator converts a given syntax tree to the corresponding SQL string.

###### Arguments:

- pretty: Whether to format the produced SQL string. Default: False.
- identify: Determines when an identifier should be quoted. Possible values are: False (default): Never quote, except in cases where it's mandatory by the dialect. True or 'always': Always quote. 'safe': Only quote identifiers that are case insensitive.
- normalize: Whether to normalize identifiers to lowercase. Default: False.
- pad: The pad size in a formatted string. For example, this affects the indentation of a projection in a query, relative to its nesting level. Default: 2.
- indent: The indentation size in a formatted string. For example, this affects the indentation of subqueries and filters under a `WHERE` clause. Default: 2.
- normalize_functions: How to normalize function names. Possible values are: "upper" or True (default): Convert names to uppercase. "lower": Convert names to lowercase. False: Disables function name normalization.
- unsupported_level: Determines the generator's behavior when it encounters unsupported expressions. Default ErrorLevel.WARN.
- max_unsupported: Maximum number of unsupported messages to include in a raised UnsupportedError. This is only relevant if unsupported_level is ErrorLevel.RAISE. Default: 3
- leading_comma: Whether the comma is leading or trailing in select expressions. This is only relevant when generating in pretty mode. Default: False
- max_text_width: The max number of characters in a segment before creating new lines in pretty mode. The default is on the smaller end because the length only represents a segment and not the true line length. Default: 80
- comments: Whether to preserve comments in the output SQL code. Default: True
