> I was looking at explain plan for IN / OR operators in a where statements, I got some conflicting results
> Non tenant query :
> here IN AND operator are on PK
> Explain Select * from CUSTOM_ENTITY."CUSTOM_ENTITY_DATA_NO_ID" Where Organization_id IN ('00Dxx0000001i28', '00Dxx0000001i29') AND Key_prefix = 'z0D';
> Explain Select * from CUSTOM_ENTITY."CUSTOM_ENTITY_DATA_NO_ID" Where (Organization_id = '00Dxx0000001i28' OR Organization_id = '00Dxx0000001i29') AND Key_prefix = 'z0D';
> Both give same result :
> CLIENT PARALLEL 32-WAY POINT LOOKUP ON 2 KEYS OVER CUSTOM_ENTITY.CUSTOM_ENTITY_DATA_NO_ID
> Tenant Specific View:
> here IN AND operator are on PK
> explain SELECT * FROM CUSTOM_ENTITY."z0D" WHERE C00NXX000001DIBOEAS IN('ROW-THREAD_1-VAL-99999','ROW-THREAD_1-VAL-99998','ROW-THREAD_1-VAL-99997')
> this is the query plan
> CLIENT PARALLEL 32-WAY POINT LOOKUP ON 3 KEYS OVER CUSTOM_ENTITY.CUSTOM_ENTITY_DATA_NO_ID
> SERVER FILTER BY PageFilter 100
> SERVER 100 ROW LIMIT
> CLIENT 100 ROW LIMIT
> But when there is an OR say for this query
> explain SELECT * FROM CUSTOM_ENTITY."z0D" WHERE (C00NXX000001DIBUEAS='ROW-THREAD_1-VAL-99998' OR C00NXX000001DIBUEAS='ROW-THREAD_1-VAL-99997')
> This is the query plan :
> CLIENT PARALLEL 32-WAY RANGE SCAN OVER CUSTOM_ENTITY.CUSTOM_ENTITY_DATA_NO_ID ['00Dxx0000001i28','z0D']
> SERVER FILTER BY (C00NXX000001DIBUEAS = 'ROW-THREAD_1-VAL-99998' OR C00NXX000001DIBUEAS = 'ROW-THREAD_1-VAL-99997')
> SERVER 100 ROW LIMIT
> CLIENT 100 ROW LIMIT
> In a tenant specific view IN and OR operators on a PK return different query plan, OR filter is doing a full range scan instead of a Point query.
