**Example 1: To update the query for a tag-based resource group**

The following ``update-group-query`` example updates the query for a tag-based resource group of Amazon EC2 instances. To update the group query, you can change the values specified for ``ResourceTypeFilters`` or ``TagFilters``. ::

    aws resource-groups update-group-query \
        --group-name WebServer3 \
        --resource-query '{"Type":"TAG_FILTERS_1_0", "Query":"{\"ResourceTypeFilters\":[\"AWS::EC2::Instance\"],\"TagFilters\":[{\"Key\":\"Name\", \"Values\":[\"WebServers\"]}]}"}'

Output::

    {
        "Group": {
            "GroupArn": "arn:aws:resource-groups:us-east-2:123456789012:group/WebServer3",
            "Name": "WebServer3"
        },
        "ResourceQuery": {
            "Type": "TAG_FILTERS_1_0",
            "Query": "{\"ResourceTypeFilters\":[\"AWS::EC2::Instance\"],\"TagFilters\":[{\"Key\":\"Name\", \"Values\":[\"WebServers\"]}]}"
        }
    }

**Example 2: To update the query for a CloudFormation stack-based resource group**

The following ``update-group-query`` example updates the query for an AWS CloudFormation stack-based resource group named ``sampleCFNstackgroup``. To update the group query, you can change the values specified for ``ResourceTypeFilters`` or ``StackIdentifier``. ::

    aws resource-groups update-group-query \
        --group-name sampleCFNstackgroup \
        --resource-query '{"Type": "CLOUDFORMATION_STACK_1_0", "Query": "{\"ResourceTypeFilters\":[\"AWS::AllSupported\"],\"StackIdentifier\":\"arn:aws:cloudformation:us-east-2:123456789012:stack/testcloudformationstack/1415z9z0-z39z-11z8-97z5-500z212zz6fz\"}"}'

Output::

    {
        "Group": {
            "GroupArn": "arn:aws:resource-groups:us-east-2:123456789012:group/sampleCFNstackgroup",
            "Name": "sampleCFNstackgroup"
        },
        "ResourceQuery": {
            "Type": "CLOUDFORMATION_STACK_1_0",
            "Query":'{\"CloudFormationStackArn\":\"arn:aws:cloudformation:us-east-2:123456789012:stack/testcloudformationstack/1415z9z0-z39z-11z8-97z5-500z212zz6fz\",\"ResourceTypeFilters\":[\"AWS::AllSupported\"]}"}'
        }
    }
