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

    402                Time taken: 4.265 seconds, Fetched 1 row(s)
    403
    404            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    405            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

    393            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    394            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    395
    396                spark-sql (default)> select cast(1234 as varchar(2));
    397                23/06/06 15:51:18 WARN CharVarcharUtils: The Spark cast operator does not support
    398                char/varchar type and simply treats them as string type. Please use string type
    399                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    400                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier
    401

    403                Time taken: 4.265 seconds, Fetched 1 row(s)
    404
    405            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    406            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

    393            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    394            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    395
    396                spark-sql (default)> select cast(1234 as varchar(2));
    397                23/06/06 15:51:18 WARN CharVarcharUtils: The Spark cast operator does not support
    398                char/varchar type and simply treats them as string type. Please use string type
    399                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    400                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier

    406            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
