NORMALIZE_FUNCTIONS: bool | str = False

Determines how function names are going to be normalized.

###### Possible values:

> "upper" or True: Convert names to uppercase. "lower": Convert names to lowercase. False: Disables function name normalization.

NULL_ORDERING = 'nulls_are_last'

Default `NULL` ordering method to use if not explicitly set. Possible values: `"nulls_are_small"`, `"nulls_are_large"`, `"nulls_are_last"`

SUPPORTS_USER_DEFINED_TYPES = False

Whether user-defined data types are supported.

SAFE_DIVISION = True

Whether division by zero throws an error (`False`) or returns NULL (`True`).

LOG_BASE_FIRST: Optional[bool] = None

Whether the base comes first in the `LOG` function. Possible values: `True`, `False`, `None` (two arguments are not supported by `LOG`)

FORCE_EARLY_ALIAS_REF_EXPANSION = True

Whether alias reference expansion (_expand_alias_refs()) should run before column qualification (_qualify_columns()).

###### For example:

> WITH data AS ( SELECT 1 AS id, 2 AS my_id ) SELECT id AS my_id FROM data WHERE my_id = 1 GROUP BY my_id, HAVING my_id = 1

In most dialects, "my_id" would refer to "data.my_id" across the query, except: - BigQuery, which will forward the alias to GROUP BY + HAVING clauses i.e it resolves to "WHERE my_id = 1 GROUP BY id HAVING id = 1" - Clickhouse, which will forward the alias across the query i.e it resolves to "WHERE id = 1 GROUP BY id HAVING id = 1"

PRESERVE_ORIGINAL_NAMES = True

Whether the name of the function should be preserved inside the node's metadata, can be useful for roundtripping deprecated vs new functions that share an AST node e.g JSON_VALUE vs JSON_EXTRACT_SCALAR in BigQuery

NUMBERS_CAN_BE_UNDERSCORE_SEPARATED = True

Whether number literals can include underscores for better readability

IDENTIFIERS_CAN_START_WITH_DIGIT = True

Whether an unquoted identifier can start with a digit.

HEX_STRING_IS_INTEGER_TYPE = True

Whether hex strings such as x'CC' evaluate to integer or binary/blob type

NORMALIZATION_STRATEGY = <NormalizationStrategy.CASE_SENSITIVE: 'CASE_SENSITIVE'>

Specifies the strategy according to which identifiers should be normalized.

UNESCAPED_SEQUENCES = {'\\a': '\x07', '\\b': '\x08', '\\f': '\x0c', '\\n': '\n', '\\r': '\r', '\\t': '\t', '\\v': '\x0b', '\\\\': '\\', '\\0': '\x00'}

Mapping of an escaped sequence (`\n`) to its unescaped version (`` ).

CREATABLE_KIND_MAPPING = {'DATABASE': 'SCHEMA'}

Helper for dialects that use a different name for the same creatable kind. For example, the Clickhouse equivalent of CREATE SCHEMA is CREATE DATABASE.

SET_OP_DISTINCT_BY_DEFAULT: Dict[Type[sqlglot.expressions.Expression], Optional[bool]] = {<class 'sqlglot.expressions.Except'>: False, <class 'sqlglot.expressions.Intersect'>: False, <class 'sqlglot.expressions.Union'>: None}

Whether a set operation uses DISTINCT by default. This is `None` when either `DISTINCT` or `ALL` must be explicitly specified.

###### 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
