Hi,
In our module IS-H (hospital) there's a view N_PFLISTEN which contains 3 tables, NFAL, NBEW and NPAT. The SQL statement of this view is:
CREATE VIEW "N_PFLISTEN"
("MANDT",
"EINRI",
"FALNR",
"LFDNR",
"FALAR",
"PATNR",
"STATUF",
"BEWTY",
"BWART",
"BWIDT",
"BWIZT",
"PLANB",
"BWEDT",
"BWEZT",
"TELNR",
"ORGPF",
"ORGFA",
"ZIMMR",
"BETT",
"PLANR",
"STORN",
"GSCHL",
"NNAME",
"NNAMS",
"VNAME",
"VNAMS",
"GBDAT",
"GBNAM",
"GBNAS",
"KONFE",
"NATIO",
"LAND",
"PSTLZ",
"ORT",
"STRAS",
"VIPKZ",
"STATU",
"VORSW",
"TODKZ",
"PLANE",
"ADRNR",
"ADROB",
"ADRN2",
"ADRO2")
AS SELECT
T2."MANDT",
T1."EINRI",
T1."FALNR",
T1."LFDNR",
T2."FALAR",
T2."PATNR",
T2."STATU",
T1."BEWTY",
T1."BWART",
T1."BWIDT",
T1."BWIZT",
T1."PLANB",
T1."BWEDT",
T1."BWEZT",
T1."TELNR",
T1."ORGPF",
T1."ORGFA",
T1."ZIMMR",
T1."BETT",
T1."PLANR",
T1."STORN",
T3."GSCHL",
T3."NNAME",
T3."NNAMS",
T3."VNAME",
T3."VNAMS",
T3."GBDAT",
T3."GBNAM",
T3."GBNAS",
T3."KONFE",
T3."NATIO",
T3."LAND",
T3."PSTLZ",
T3."ORT",
T3."STRAS",
T3."VIPKZ",
T3."STATU",
T3."VORSW",
T3."TODKZ",
T1."PLANE",
T3."ADRNR",
T3."ADROB",
T3."ADRN2",
T3."ADRO2"
FROM
"NBEW" T1,
"NFAL" T2,
"NPAT" T3
WHERE
T2."MANDT" = T1."MANDT" AND
T2."EINRI" = T1."EINRI" AND
T2."FALNR" = T1."FALNR" AND
T3."MANDT" = T2."MANDT" AND
T3."PATNR" = T2."PATNR"
Now there's the following ABAP-selection:
SELECT (p_fieldlist)
FROM n_pflisten INTO CORRESPONDING FIELDS OF TABLE sel_pflisten
FOR ALL ENTRIES IN p_npfo
WHERE einri = p_npfo-einri
AND falnr = p_npfo-falnr
AND falar IN rfalar
AND storn = off.
In the execution plan of this view there's a table scan for NFAL, but the Key-fields of nfal are EINRI and FALNR. These fields are filled in internal table p_npfo !!
Why is this selection using a Table Scan and doesn't it take the primary index ???
Kind regards,
Gert-Jan
Hi Gert-Jan,
I take it you're talking about the OSS message 152419 2007. This message is already being analyzed by a colleague of mine (MaxDB Development Support) and therefore I suggest to close this thread, as you'll get an answer in the official call as soon as the cause of the issue has been found.
Kind regards,
Roland
