Hi guys i need some help about split in Oracle's SQL i get ACENTE_AD x character and i wanna see only first 5 character. and i get CEpTELEFON like 012345678 and i wanna split first 3 character(012) in a column and last 6 character(345678) the in other column. thanks.

Answer 1

You can use substr() string manipulation function to split your phone value in the outer select statement by considering your original query as a subquery.
SELECT t.Bayi_Yetkili_Kisi, t.Vkn_No, t.Adres,
substr(CepTelefonu,1,3) as AlanKodu, substr(CepTelefonu,-6) as CepTelefonu
FROM
(
SELECT MR.MUSTERI_ROL_AD AS ACENTE_AD,
(SELECT mrrt.musteri_rol_ad
FROM musteri_rol mrrt
JOIN calisan ct ON ct.calisan_rol_id = mrrt.musteri_rol_id
JOIN musteri mmt ON mmt.musteri_id = mrrt.musteri_id
WHERE ct.bagli_rol_id = a.acente_id
AND ct.teknik_personel = 'H'
AND ct.calisan_rol_id is not null
AND rownum < 2) as Bayi_Yetkili_Kisi,
(CASE
WHEN M.TCK_NO is null THEN
M.VKN_NO
ELSE
null
END) as Vkn_No,
(SELECT (SELECT taa.adresi
FROM tobb_acente ta
JOIN tobb_acente_adres taa
ON taa.tobb_acente_sorgu_id = ta.tobb_acente_sorgu_id
WHERE ta.levhano = a.levha_no
AND rownum < 2)
FROM musteri mt
JOIN musteri_rol mrt ON mrt.musteri_id = mt.musteri_id
LEFT JOIN musteri_adres mat ON mat.musteri_id = mt.musteri_id
LEFT JOIN adres ad ON ad.adres_id = mat.adres_id
WHERE mrt.musteri_rol_id = a.acente_id
AND rownum < 2) as Adres,
(SELECT mi.aciklama
FROM musteri_iletisim mi
JOIN musteri_rol_iletisim mri ON mri.musteri_iletisim_id = mi.musteri_iletisim_id
WHERE mi.musteri_id = m.musteri_id
AND mi.iletisim_tip_kod = pck_const_iletisim_tip.cep_telefon() -- I think the right hand side implies a stored function, doesn't it?
AND mri.musteri_rol_id = mr.musteri_rol_id
AND rownum < 2) as CepTelefonu
FROM MUSTERI_ROL MR
JOIN MUSTERI M ON M.MUSTERI_ID = MR.MUSTERI_ID
JOIN ACENTE A ON A.ACENTE_ID = MR.MUSTERI_ROL_ID
JOIN SATIS_KANALI SK ON SK.SATIS_KANALI_ID = A.SATIS_KANALI_ID
WHERE MR.ROL_ID = 1
AND A.Uretim_Kaynagi = 'E'
AND A.UST_ACENTE_ID is null
AND MR.Ust_Musteri_Rol_Id is null

OR MR.Bitis_Tarih = sysdate

Btw, Consider using ANSI-92 style SQL rather than former ANSI-89 with comma-seperated tables written like the above one. It's easier to write, understand and maintain.
