Good morning,
I have a problem and I am currently blocked the above, I hope any help , my problem is as follows:
I must write PL / SQL, requette SQL which makes a search (a search engine) on several tables (at least 8 => several joints) on fields that can be NULL, empty, full ... I do not recover as the list of id of the table (ROOT), this is how I have done, but it did not work
| Quote: |
SELECT tableRoot.Id
FROM table_root tableRoot,
table_fille1 fille1,
table_fille2 fille2,
table_fille3 fille3,
table_fille4 fille4,
...
WHERE
tableRoot.champRoot1 LIKE '%i__var1%' AND
tableRoot.champRoot2 = i__var2 AND
tableRoot.champRoot3 = i__var3 AND
fille1.champfille1_1 = i__var4 AND
fille1.champfille1_2 = i__var5 AND
fille2.champfille2 LIKE '%i__var6 %' AND
fille3.champfille3 LIKE '%i__var7 %' AND
fille4.champfille4_1 LIKE '%i__var8 %' AND
fille4.champfille4_2 LIKE '%i__var9 %' AND
...
-- Inner joins
fille1.id = tableRoot.fk_id_1 AND
fille2.id = tableRoot.fk_id_2 AND
fille3.id = tableRoot.fk_id_3 AND
fille4.id = tableRoot.fk_id_4
...; |
thank's  |

Good morning
can you give a little more detail?
what does not?
a small example can be reduced to a child table to show us what you really want and what you problem?
Thanks |

hi Thank's for your response
Already the first question that arises: Is what I'm on the right path, is this the way forward? y'aurais no problems fall performance, if information does not exist at a table which has been doing a join, it will not affect the requette short, you see problems in this method?  |

hi,
Already performance level will require that you use indexes
According without more information, it is difficult to say any more worry. |

look at : y'aurais . . . french???
if you want to send a translated text to someone or use it for your correspondence, explain that you always use a translator ...  because there, you writing as the noobs i can not understand what you talked about because your language is very bad
and i think that "str0xo", "Nuckel", "dzH" are the same person by different nickname, the IP used. . 
see u . . |
