    374            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    375            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    376
    377                spark-sql (default)> select cast(1234 as varchar(2));
    378                23/06/06 15:51:18 WARN CharVarcharUtils: The Spark cast operator does not support
    379                char/varchar type and simply treats them as string type. Please use string type
    380                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    381                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier

    385
    386            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    387            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

    375            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    376            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    377
    378                spark-sql (default)> select cast(1234 as varchar(2));

    381                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    382                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier

    375            Spark (and most likely Hive) treats casts to CHAR(length) and VARCHAR(length) as casts to
    376            STRING in all contexts except for schema definitions. For example, this is in Spark v3.4.0:
    377
    378                spark-sql (default)> select cast(1234 as varchar(2));
    379                23/06/06 15:51:18 WARN CharVarcharUtils: The Spark cast operator does not support
    380                char/varchar type and simply treats them as string type. Please use string type
    381                directly to avoid confusion. Otherwise, you can set spark.sql.legacy.charVarcharAsString
    382                to true, so that Spark treat them as string type as same as Spark 3.0 and earlier
    383
    384                1234
    385                Time taken: 4.265 seconds, Fetched 1 row(s)
    386
    387            This shows that Spark doesn't truncate the value into '12', which is inconsistent with
    388            what other dialects (e.g. postgres) do, so we need to drop the length to transpile correctly.

###### Arguments:

- error_level: The desired error level. Default: ErrorLevel.IMMEDIATE
- error_message_context: Determines 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 or not 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 or not to normalize identifiers to lowercase. Default: False.
- pad: Determines the pad size in a formatted string. Default: 2.
- indent: Determines the indentation size in a formatted string. Default: 2.
- normalize_functions: Whether or not to normalize all 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: Determines whether or not 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 or not to preserve comments in the output SQL code. Default: True
