This makes it difficult +to write portable SQL code. SQLGlot bridges all the different variations, called "dialects", with an extensible +SQL transpilation framework. + +The base `sqlglot.dialects.dialect.Dialect` class implements a generic dialect that aims to be as universal as possible. + +Each SQL variation has its own `Dialect` subclass, extending the corresponding `Tokenizer`, `Parser` and `Generator` +classes as needed. + +### Implementing a custom Dialect + +Creating a new SQL dialect may seem complicated at first, but it is actually quite simple in SQLGlot: + +```python +from sqlglot import exp +from sqlglot.dialects.dialect import Dialect +from sqlglot.generator import Generator +from sqlglot.tokens import Tokenizer, TokenType + + +class Custom(Dialect): + class Tokenizer(Tokenizer): + QUOTES = ["'", '"'] # Strings can be delimited by either single or double quotes + IDENTIFIERS = ["`"] # Identifiers can be delimited by backticks + + # Associates certain meaningful words with tokens that capture their intent + KEYWORDS = { + **Tokenizer.KEYWORDS, + "INT64": TokenType.BIGINT, + "FLOAT64": TokenType.DOUBLE, + } + + class Generator(Generator): + # Specifies how AST nodes, i.e. subclasses of exp.Expression, should be converted into SQL + TRANSFORMS = { + exp.Array: lambda self, e: f"[{self.expressions(e)}]", + } + + # Specifies how AST nodes representing data types should be converted into SQL + TYPE_MAPPING = { + exp.DataType.Type.TINYINT: "INT64", + exp.DataType.Type.SMALLINT: "INT64", + exp.DataType.Type.INT: "INT64", + exp.DataType.Type.BIGINT: "INT64", + exp.DataType.Type.DECIMAL: "NUMERIC", + exp.DataType.Type.FLOAT: "FLOAT64", + exp.DataType.Type.DOUBLE: "FLOAT64", + exp.DataType.Type.BOOLEAN: "BOOL", + exp.DataType.Type.TEXT: "STRING", + } +``` + +The above example demonstrates how certain parts of the base `Dialect` class can be overridden to match a different +specification.
