class Generator:
"""
Generator interprets the given syntax tree and produces a SQL string as an output.
Generator converts a given syntax tree to the corresponding SQL string.
Args:
time_mapping (dict): the dictionary of custom time mappings in which the key
represents a python time format and the output the target time format
time_trie (trie): a trie of the time_mapping keys
pretty (bool): if set to True the returned string will be formatted. Default: False.
quote_start (str): specifies which starting character to use to delimit quotes. Default: '.
quote_end (str): specifies which ending character to use to delimit quotes. Default: '.
identifier_start (str): specifies which starting character to use to delimit identifiers. Default: ".
identifier_end (str): specifies which ending character to use to delimit identifiers. Default: ".
bit_start (str): specifies which starting character to use to delimit bit literals. Default: None.
bit_end (str): specifies which ending character to use to delimit bit literals. Default: None.
hex_start (str): specifies which starting character to use to delimit hex literals. Default: None.
hex_end (str): specifies which ending character to use to delimit hex literals. Default: None.
byte_start (str): specifies which starting character to use to delimit byte literals. Default: None.
byte_end (str): specifies which ending character to use to delimit byte literals. Default: None.
raw_start (str): specifies which starting character to use to delimit raw literals. Default: None.
raw_end (str): specifies which ending character to use to delimit raw literals. Default: None.
identify (bool | str): 'always': always quote, 'safe': quote identifiers if they don't contain an upcase, True defaults to always.
normalize (bool): if set to True all identifiers will lower cased
string_escape (str): specifies a string escape character. Default: '.
identifier_escape (str): specifies an identifier escape character. Default: ".
pad (int): determines padding in a formatted string. Default: 2.
indent (int): determines the size of indentation in a formatted string. Default: 4.
unnest_column_only (bool): if true unnest table aliases are considered only as column aliases
normalize_functions (str): normalize function names, "upper", "lower", or None
Default: "upper"
alias_post_tablesample (bool): if the table alias comes after tablesample
Default: False
identifiers_can_start_with_digit (bool): if an unquoted identifier can start with digit
Default: False
unsupported_level (ErrorLevel): determines the generator's behavior when it encounters
unsupported expressions. Default ErrorLevel.WARN.
null_ordering (str): Indicates the default null ordering method to use if not explicitly set.
Options are "nulls_are_small", "nulls_are_large", "nulls_are_last".
Default: "nulls_are_small"
max_unsupported (int): Maximum number of unsupported messages to include in a raised UnsupportedError.
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 (bool): if the the comma is leading or trailing in select statements
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
