How To Calling a Stored Procedure in Worklight

问题:

I have just started working on IBM Worklight. I ran a SQL Adapter , in which it uses the procedure to fetch data from database and displays in JSON format.But I want to use that stored procedure in my HTML file regarding to display records in my frontend UI. please provide me any suggestion.

Once you have written and tested your adapter you can invoke the adapter from an application using this syntax:

function getData() {
var invocationData = {
        adapter : 'ADAPTER_NAME',
        procedure : 'PROCEDURE_NAME',
        parameters : []
    };

WL.Client.invokeProcedure(invocationData,{
    onSuccess : getDataSuccess,
    onFailure : getDataFailure,
});
}

OnSuccess (when the data is returned to the application) calls (in this example) a function called getDataSuccess. This function will receive the JSON data returned from the Worklight server.

onFailure calls (in this example) a function called getDataFailure that will receive the error sent from the Worklight server.
