# 3251 SQL Execution Plan Hints Showing Incorrectly for Certain Conditions

The following query results in a weird hint in the execution plan:

Row scan (Companies): 7128 rows, 3364416 bytes estimated cost

Hint: Create index (Companies) on column "_fkOrgType","_fkOrgType","_fkOrgType"
"_fkOrgType","_fkOrgType","_fkOrgType","_fkOrgType","_fkOrgType","_fkOrgType"
"_fkOrgType","_fkOrgType" for possible better performance

SELECT ALL
"_ID" AS "_ID"
FROM "Companies" INNER JOIN "Career" ON "_fkCompanies" = "Companies"."_ID"
WHERE ("_fkOrgType" = 'A/ELEC' OR "_fkOrgType" = 'AERO' OR "_fkOrgType" =
'APPLEGATE' OR "_fkOrgType" = 'CAPEX' OR "_fkOrgType" = 'DEFENCE' OR "_fkOrgType" =
'ELECTRONIC' OR "_fkOrgType" = 'HQ' OR "_fkOrgType" = 'MAKER' OR "_fkOrgType" =
'MECHENG' OR "_fkOrgType" = 'NONCORE' OR "_fkOrgType" = 'PHARM' OR "_fkOrgType" =
'PROCESS') AND EXISTS (SELECT ALL "_fkCompanies" AS "_fkCompanies" FROM
"Career" WHERE "_fkCompanies" = "Companies"."_ID" AND "_fkJobCodes" IN ('GM', 'CEO',
'MD')) <> TRUE
