Protected Readonly[SQL_ReadonlyargsThis getter is designed to be used as an attribute's default value. This is useful when the SQL version must be bypassed due to a limitation of the dialect that Sequelize cannot detect, such as a missing extension.
const User = sequelize.define('User', {
uuid: {
type: DataTypes.UUID,
defaultValue: sql.uuidV4.asJavaScript,
},
});

Unlike sql.fn, this class does not accept a function name. It must instead be extended by a class that implements the applyForDialect method, in which the function name is provided.
The goal of this class is to allow dialect-specific functions to be used in a cross-dialect way. For instance, an extension of this class could be used to represent the
LOWERfunction in a cross-dialect way, by generating the correct SQL function name based on which dialect is used.
