To update a GraphQL query on button click, you can use a state variable to store the query parameters and update them when the button is clicked. Here's an example of how you can achieve this using React:

import React, { useState } from 'react';
import { useQuery } from '@apollo/client';
import { YOUR_QUERY } from './queries';

const App = () => {
  const [queryVariable, setQueryVariable] = useState('initialValue');

  const { data, loading, error } = useQuery(YOUR_QUERY, {
    variables: { queryVariable },
  });

  const handleButtonClick = () => {
    setQueryVariable('newValue');
  };

  if (loading) return <p>Loading...</p>;
  if (error) return <p>Error: {error.message}</p>;

  return (
    <div>
      <button onClick={handleButtonClick}>Update Query</button>
      <p>{data && data.field}</p>
    </div>
  );
};

export default App;


In this example, we have a state variable queryVariable that stores the value of the query parameter. When the button is clicked, the handleButtonClick function updates the queryVariable to a new value. The GraphQL query is then executed with the updated variable value, and the data is displayed in the component.


Make sure to replace YOUR_QUERY with your actual GraphQL query and update the query structure according to your needs.
