API return breaks when using inner join?

Question

I've been building an API which was working absolutely fine until I tried to add an inner join

The SQL I'm passing returns as I'd expect when I run it in Beaver (am using Mac)

However, when I try and access it via my API end point, instead of the combined results, I get only results from the table I added in the join

I presume am doing something really stupid ...

From my controller:

result = dbtest.FromDatabase(
    "SELECT A.FAMILY_ID
        ,A.START_TIME
        ,A.END_TIME
        ,A.WORKER_ID
        ,A.WEEK_NO
        ,A.ID
        ,A.SHIFT_NO
        ,A.DAY_OF_WEEK
        ,A.HOLIDAY_OR_TERM
        ,B.WORKER_NAME
    FROM SHIFT_REQ_TBL A
    INNER JOIN WORKER_TBL B ON A.WORKER_ID = B.WORKER_ID
    WHERE A.FAMILY_ID = '" + FAMILY.FAMILY_ID + "'");

From my model

if (query.Contains("SHIFT_REQ_TBL"))
{
    var tbl_type = new TimekeeperTables.SHIFT_REQ_TBL();

    tbl_type.FAMILY_ID = Convert.ToInt32(reader["FAMILY_ID"]);
    tbl_type.ID = Convert.ToInt32(reader["ID"]);
    tbl_type.WEEK_NO = Convert.ToInt32(reader["WEEK_NO"]);
    tbl_type.WORKER_ID = Convert.ToInt32(reader["WORKER_ID"]);

    tbl_type.SHIFT_NO = reader["SHIFT_NO"].ToString();
    tbl_type.START_TIME = reader["START_TIME"].ToString();
    tbl_type.END_TIME = reader["END_TIME"].ToString();
    tbl_type.DAY_OF_WEEK = reader["DAY_OF_WEEK"].ToString();
    tbl_type.HOLIDAY_OR_TERM = reader["HOLIDAY_OR_TERM"].ToString();
    tbl_type.WORKER_NAME = reader["WORKER_NAME"].ToString();

    db_results.Add(tbl_type);
    jsonDoc = JsonConvert.SerializeObject(db_results);
}

Results (from postman)

Answer 1

I'm sorry, I was being stupid and figured it out

I was using a really dumb way of identifying the calling URL which already was checking for SHIFT_TBL in an earlier case
