Question On Extracting Query Variables

[magicMustard]

Hello,

I have a question about your engine that converts the gql to sql.

Well, my question is the following:

Take the following query example:

query {
user {
first_name,
last_name
}
}

I'm playing around with a few things and reading through the code, but I'm a little lost.

Are there any functions that are callable that can read the query and provide back a list of the columns requested (i.e. first_name, last_name) is say a slice []string object?

Further to that, a function that gets the table, i.e. user.

Essentially, I'm playing around with a few things and would like to know more info as to what parts of your engine extract that information.

Much appreciated.

Lookat core/internal/qcode/qcode_test.go you have to create a qcode.NewCompiler instance and then call Compile on it.
This function takes the query and compiles it into an internal representation called qcode. The function in qcode that does most of the work is called compileQuery and it uses a function called compileColumns . This function uses sel.Ti.GetColumn(f.Name) to get the db column information for each field and populate the Cols and BCols fields on the Select struct under the QCode struct`
