Question

I’m trying to add all the values in a column to get the total of that column, anyone know the trick to this?

Here’s my query:

select T.*,
sum(nvl(BIN1,0))+sum(nvl(BIN2,0))+sum(nvl((BIN3,0)) as TOTAL
from
(
  SELECT CSM_FLASKS.FLASK_CODE,
    MN_ASSAYS_STAGES.ASSAY_STAGE_ID,
    VITRO_REP.TREATMENT_DOSE(CSM_FLASKS.GROUP_ID)                                               AS TREATMENT_DOSE,
    MN_RI_REP.FLASK_BIN_VALUE_BY_INDEX(MN_ASSAYS_STAGES.ASSAY_STAGE_ID, CSM_FLASKS.FLASK_ID, 1) AS BIN1,
    MN_RI_REP.FLASK_BIN_VALUE_BY_INDEX(MN_ASSAYS_STAGES.ASSAY_STAGE_ID, CSM_FLASKS.FLASK_ID, 2) AS BIN2,
    MN_RI_REP.FLASK_BIN_VALUE_BY_INDEX(MN_ASSAYS_STAGES.ASSAY_STAGE_ID, CSM_FLASKS.FLASK_ID, 3) AS BIN3,
    MN_RI_REP.CBPI_FLASK(MN_ASSAYS_STAGES.ASSAY_STAGE_ID, CSM_FLASKS.FLASK_ID, 1, 2, 2)         AS CBPI,
    CSM_EXPERIMENTS.EXPT_CODE
  FROM CSM_TREATMENT_GROUPS_EXPTS
  INNER JOIN CSM_ASSAYS
  ON CSM_ASSAYS.EXPT_ID = CSM_TREATMENT_GROUPS_EXPTS.EXPERIMENT_ID
  INNER JOIN CSM_FLASKS
  ON CSM_TREATMENT_GROUPS_EXPTS.GROUP_ID = CSM_FLASKS.GROUP_ID
  INNER JOIN MN_ASSAYS
  ON CSM_ASSAYS.ASSAY_ID = MN_ASSAYS.ASSAY_ID
  INNER JOIN MN_ASSAYS_STAGES
  ON MN_ASSAYS.MN_ASSAY_ID = MN_ASSAYS_STAGES.MN_ASSAY_ID
  INNER JOIN CSM_EXPERIMENTS
  ON CSM_EXPERIMENTS.EXPT_ID    = CSM_TREATMENT_GROUPS_EXPTS.EXPERIMENT_ID
  AND CSM_EXPERIMENTS.EXPT_ID   = CSM_ASSAYS.EXPT_ID
  WHERE CSM_ASSAYS.ASSAY_ID     = 1000060
  AND MN_ASSAYS_STAGES.STAGE_ID = 2
  ORDER BY CSM_TREATMENT_GROUPS_EXPTS.ORDER_INDEX,
    CSM_FLASKS.FLASK_ID,
    CSM_FLASKS.IS_PLUS DESC
) T

Error:

Answer 1

When using any aggregate function, you will need to add the non aggregated fields into a GROUP BY clause. So in your column you need to list those fields that are not listed in the aggregate function SUM in the GROUP BY clause. Therefore your query should be as following:

SELECT FLASK_CODE,
SUM(nvl(BIN1, 0)) + SUM(nvl(BIN2, 0)) + SUM(nvl((BIN3, 0)) AS TOTAL
FROM
(
  ...

) T
GROUP BY FLASK_CODE

This is just an example. But you have to determine what fields to select in the SELECT clause and needs to be listed too in GROUP BY clause.
