Import export in React Query builder component
10 Apr 202324 minutes to read
Importing allows you to view or edit the predefined conditions which is available in JSON or SQL. You can import the conditions either initial rendering or post rendering.
Initial rendering
To apply conditions initially, you can define the rule
. Here, you can import structured JSON object by defining the rule
property.
import { QueryBuilderComponent } from '@syncfusion/ej2-react-querybuilder';
import * as React from 'react';
import * as ReactDom from 'react-dom';
// @ts-ignore
import { hardwareData } from '../datasource.ts';
function App() {
let columnData = [
{ field: 'TaskID', label: 'Task ID', type: 'number' },
{ field: 'Name', label: 'Name', type: 'string' },
{ field: 'Category', label: 'Category', type: 'string' },
{ field: 'SerialNo', label: 'Serial No', type: 'string' },
{ field: 'InvoiceNo', label: 'Invoice No', type: 'string' },
{ field: 'Status', label: 'Status', type: 'string' }
];
let importRules = {
'condition': 'or',
'rules': [{
'field': 'Category',
'label': 'Category',
'operator': 'equal',
'type': 'string',
'value': 'Laptop'
},
{
'condition': 'and',
'rules': [{

};

}
export default App;
ReactDom.render(<App />, document.getElementById('querybuilder'));

'operator': 'equal',
'type': 'number',
'value': 5675

}]
};
return (
<QueryBuilderComponent width='100%' dataSource={hardwareData} columns={columnData} rule={importRules}/>
);
}
export default App;
ReactDom.render(<App />,document.getElementById('querybuilder'));
Post rendering
Importing from JSON
You can set the conditions from structured JSON object through the setRules
method.

};
function onClick() {
qryBldrObj.setRules(importRules);
}
return (<div>
<QueryBuilderComponent width='100%' dataSource={hardwareData} ref={(scope) => { qryBldrObj = scope; }} columns={columnData}/>
<div className="e-qb-button">
<ButtonComponent id="importrules" cssClass='e-primary' content='Set Rules' onClick={onClick}/>
</div>
</div>);

Importing from SQL
You can set the conditions from SQL query through the setRulesFromSql
method.

];
function importRule() {
qryBldrObj.setRulesFromSql("TaskID = 1 and Status LIKE ('Assigned%')");
}
return (<div>

</div>
</div>);
}

Exporting
10 Apr 202324 minutes to read
Exporting allows you to save or maintain the created conditions through the Query Builder. You can export the defined conditions by the following ways.
Exporting to JSON
You can export the defined conditions to structured JSON object through the getRules
method.
Exporting to SQL
You can export the defined conditions to SQL query through the getSqlFromRules
method.
