I want to assign values returned from an SQL query to a multidimensional struct. I want to output this multidimensional struct as JSON to a Web frontend.
Edit: SQL query is simple, 'SELECT * FROM policy'. It returns many key/values but for the purpose of the example I'm just using the 'policy_id', 'class_id' and 'name' fields.
My Structs
type table struct {
Policy string `json:"policy"`
P []Parameters `json:"parameters"`
}
type Parameters struct {
Policy_id string `json:"policy_id"`
Class_id string `json:"class_id"`
Name string `json:"name"`
.... <removed many more entries of the same type>
}
I then loop through the SQL output using rows.Next() // not important for the question.
If I do:
p := Parameters{}
then:
err = rows.Scan(&p.Policy_id, &p.Class_id, &p.Name)
p is populated with the key / values pairs I'd expect.
Edit: I added p.Name as I want to use the Name returned from the query string as the unique key for the table struct. This wasn't clear before.
However, I want to get the data into the higher level struct 'table'. I eventually want the output to look something like this in JSON:
{policy: "policyName1", P: [{policy_id: '1', class_id:'01"},{policy_id: '2', class_id: '02'}, etc]}
I've tried things like this:
t := table {
Policy: p.Name,
P: p,
}
And a few other combinations, but at this point I'm just guessing. Can someone point me in the right direction?
