Working with queries in C/AL

We can run a query and retrieve data using the C/AL code. To achieve this, NAV provides several functions. This recipe will demonstrate a simple example of executing a query using C/AL code.

How to do it...

Follow the steps from the Using a query to extract data recipe to create a query and save it as Customer Balance.
Create a new codeunit with Object Designer.
Add the following local variable to the run trigger:

Name

Type

Subtype

CustBalance

Query

Customer Balance

Name	Type	Subtype
`CustBalance`	`Query`	`Customer Balance`

Add the following code into the OnRun trigger of the codeunit:

CustBalance.TOPNUMBEROFROWS(2);
CustBalance.SETFILTER(Balance, '>10000');
CustBalance.OPEN;
WHILE CustBalance.READ DO
BEGIN
MESSAGE('Customer Name : %1 \Balance : %2',   CustBalance.Name,CustBalance.Balance);
END;
CustBalance.CLOSE;

Save and close the codeunit.
On executing the codeunit, you should see a window similar to the one shown in the following screenshot:

How it works...

We use the dataset provided by the Customer Balance...
