Question

i have this statement in access:

SELECT *
FROM accountsnew
WHERE [Panels] not like '*IT_OXYC,*' and [Panels] not like '*OXY_SN,*' and [Panels] not like '*OXY_S,*' and [Panels] not like '*OXY_N,*' and [Panels] like '*OXYC_SNEG,*' or [Panels] like '*OXYC_PNEG,*';

for some reason it is not returning the proper dataset. when i look more deeply at the data returned, using excel, i see that what it returned in fact DID contain IT_OXYC, and some other parameters.

is there something wrong with my statement?

i am trying to get all records which do not have IT_OXYC, OXY_SN , OXY_S, etc… and DO have either OXYC_SNEG, or OXYC_PNEG,

Answer 1

Your logic is wrong. Translating your request bit-by-bit:

I am trying to get all records

SELECT * FROM accountsnew

which do not

WHERE NOT (…)

have IT_OXYC or OXY_SN or OXY_S, etc…

(x LIKE ‘IT_OXYC‘ OR x LIKE ‘IOXY_SN‘ OR x LIKE ‘OXY_S‘ OR …)

and DO have either OXYC_SNEG, or OXYC_PNEG,

AND (x LIKE ‘OXYC_SNEG‘ OR x LIKE ‘OXYC_PNEG‘)

Putting it all together:

SELECT *
FROM accountsnew
WHERE NOT ([Panels] LIKE '*IT_OXYC*' OR
           [Panels] LIKE '*IOXY_SN*' OR
           [Panels] LIKE '*OXY_S*' OR ...)
AND ([Panels] LIKE '*OXYC_SNEG*' OR 
     [Panels] LIKE '*OXYC_PNEG*')
