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

    397
    398            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    399            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

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

    398
    399            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    400            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

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

    400            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
