    """
    Inserts or deletes  SqlInjectionMatchTuple objects (filters) in a  SqlInjectionMatchSet . For each SqlInjectionMatchTuple object, you specify the following values:
    You use SqlInjectionMatchSet objects to specify which CloudFront requests you want to allow, block, or count. For example, if you're receiving requests that contain snippets of SQL code in the query string and you want to block the requests, you can create a SqlInjectionMatchSet with the applicable settings, and then configure AWS WAF to block the requests.
    To create and configure a SqlInjectionMatchSet , perform the following steps:
    For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .

    The following example deletes a SqlInjectionMatchTuple object (filters) in a SQL injection match set with the ID example1ds3t-46da-4fdb-b8d5-abc321j569j5.

    :type SqlInjectionMatchSetId: string
    :param SqlInjectionMatchSetId: [REQUIRED]
            The SqlInjectionMatchSetId of the SqlInjectionMatchSet that you want to update. SqlInjectionMatchSetId is returned by CreateSqlInjectionMatchSet and by ListSqlInjectionMatchSets .
            

    :type ChangeToken: string
    :param ChangeToken: [REQUIRED]
            The value returned by the most recent call to GetChangeToken .
            

    :type Updates: list
    :param Updates: [REQUIRED]
            An array of SqlInjectionMatchSetUpdate objects that you want to insert into or delete from a SqlInjectionMatchSet . For more information, see the applicable data types:
            SqlInjectionMatchSetUpdate : Contains Action and SqlInjectionMatchTuple
            SqlInjectionMatchTuple : Contains FieldToMatch and TextTransformation
            FieldToMatch : Contains Data and Type
            (dict) --Specifies the part of a web request that you want to inspect for snippets of malicious SQL code and indicates whether you want to add the specification to a SqlInjectionMatchSet or delete it from a SqlInjectionMatchSet .
            Action (string) -- [REQUIRED]Specify INSERT to add a SqlInjectionMatchSetUpdate to a SqlInjectionMatchSet . Use DELETE to remove a SqlInjectionMatchSetUpdate from a SqlInjectionMatchSet .
            SqlInjectionMatchTuple (dict) -- [REQUIRED]Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.
            FieldToMatch (dict) -- [REQUIRED]Specifies where in a web request to look for snippets of malicious SQL code.
            Type (string) -- [REQUIRED]The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
            HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
            METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
            QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
            URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
            BODY : The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
            Data (string) --When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
            The name of the header is not case sensitive.
            TextTransformation (string) -- [REQUIRED]Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting a request for a match.
            CMD_LINE
            When you're concerned that attackers are injecting an operating system commandline command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
            Delete the following characters: ' ' ^
            Delete spaces before the following characters: / (
            Replace the following characters with a space: , ;
            Replace multiple spaces with one space
            Convert uppercase letters (A-Z) to lowercase (a-z)
            COMPRESS_WHITE_SPACE
            Use this option to replace the following characters with a space character (decimal 32):
            f, formfeed, decimal 12
            t, tab, decimal 9
            n, newline, decimal 10
            r, carriage return, decimal 13
            v, vertical tab, decimal 11
            non-breaking space, decimal 160
            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.HTML_ENTITY_DECODE
            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
            Replaces (ampersand)quot; with '
            Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
            Replaces (ampersand)lt; with a 'less than' symbol
            Replaces (ampersand)gt; with ````
            Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
            Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
            LOWERCASE
            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
            URL_DECODE
            Use this option to decode a URL-encoded value.
            NONE
            Specify NONE if you don't want to perform any text transformations.

    :return: {
        'ChangeToken': 'string'
    }
    
    
    :returns: 
    Submit a  CreateSqlInjectionMatchSet request.
    Use  GetChangeToken to get the change token that you provide in the ChangeToken parameter of an  UpdateIPSet request.
    Submit an UpdateSqlInjectionMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for snippets of SQL code.
