We don't think you should sweat the difference between `varchar(256)` and `varchar(257)`, because it doesn't really affect the experience of downstream queriers. If you need a more-precise assertion, it's always possible to accomplish by [writing or using a custom test](/guides/best-practices/writing-custom-generic-tests). -You need to specify a varchar size or numeric scale, otherwise dbt relies on default values. For example, if a `numeric` type defaults to a precision of 38 and a scale of 0, then the numeric column stores 0 digits to the right of the decimal (it only stores whole numbers), which might cause it to fail contract enforcement. To avoid this implicit coercion, specify your `data_type` with a nonzero scale, like `numeric(38, 6)`. dbt Core 1.7 and higher provides an error if you don't specify precision and scale when providing a numeric data type. +Just remember, you need to specify a varchar size or numeric scale, otherwise dbt relies on default values.
