Discussion

The a5wcb_graphQLQueryBuilder() function can be used to open the GraphIQL Query Tester window to create a GraphQL Query.

For example, assume you have defined a GraphQL service (called Northwind.a5svc) that exposes data from tables in the sample Northwind database.

To build a query, go to the Interactive window and type (pressing Enter after each line):

dim result as p
result = a5wcb_graphQLQueryBuilder("[workingpreview]","northwind")

The GraphIQL tester will open in a window. You can enter a query definition and test it. When you are done, click the Save button in the bottom right corner.

To see the query string that you defined, enter:

showvar(result.query)

To see any query variables that you defined, enter:

showvar(result.vars)
