# PUT /rulesets/{name}

`PUT /rulesets/{name}`

Updates specified ruleset.

## Path parameters

- `name` string, required

## Request body

- object
  - `Description` string — The description of the ruleset.
  - `Rules` Rule[], required — A list of rules that are defined with the ruleset. A rule includes one or more checks to be validated on a DataBrew dataset.
    - `Name` string, required — The name of the rule.
    - `Disabled` boolean — A value that specifies whether the rule is disabled. Once a rule is disabled, a profile job will not validate it during a job run. Default value is false.
    - `CheckExpression` string, required — <p>The expression which includes column references, condition names followed by variable references, possibly grouped and combined with other conditions. For example, <code>(:col1 starts_with :prefix1 or :col1 starts_with :prefix2) and (:col1 ends_with :suffix1 or :col1 ends_with :suffix2)</code>. Column and value references are substitution variables that should start with the ':' symbol. Depending on the context, substitution variables' values can be either an actual value or a column name. These values are defined in the SubstitutionMap. If a CheckExpression starts with a column reference, then ColumnSelectors in the rule should be null. If ColumnSelectors has been defined, then there should be no column reference in the left side of a condition, for example, <code>is_between :val1 and :val2</code>.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/databrew/latest/dg/profile.data-quality-available-checks.html">Available checks</a> </p>
    - `SubstitutionMap` object — The map of substitution variable names to their values used in a check expression. Variable names should start with a ':' (colon). Variable values can either be actual values or column names. To differentiate between the two, column names should be enclosed in backticks, for example, <code>":col1": "`Column A`".</code>
    - `Threshold` object — The threshold used with a non-aggregate check expression. Non-aggregate check expressions will be applied to each row in a specific column, and the threshold will be used to determine whether the validation succeeds.
      - `Value` number, double, required — The value of a threshold.
      - `Type` 'GREATER_THAN_OR_EQUAL' | 'LESS_THAN_OR_EQUAL' | 'GREATER_THAN' | 'LESS_THAN' — The type of a threshold. Used for comparison of an actual count of rows that satisfy the rule to the threshold value.
      - `Unit` 'COUNT' | 'PERCENTAGE' — Unit of threshold value. Can be either a COUNT or PERCENTAGE of the full sample size used for validation.
    - `ColumnSelectors` ColumnSelector[] — List of column selectors. Selectors can be used to select columns using a name or regular expression from the dataset. Rule will be applied to selected columns.
      - `Regex` string — A regular expression for selecting a column from a dataset.
      - `Name` string — The name of a column from a dataset.

## Response `200`

Success

- UpdateRulesetResponse
  - `Name` string, required — The name of the updated ruleset.

## Other responses

- `480` — ResourceNotFoundException
- `481` — ValidationException
