You can have multiple outer joins in the where clause but one table can be outer-joined to one other table only.
For example you can write: select tb1.col_1 from table1 tb1, table2 tb2, table3 tb3 where tb1.some_col = "some value" and tb1.col_a(+) = tb2.col_a and tb2.col_b(+) = tb3.col_b but you can not write: select tb1.col_1 from table1 tb1, table2 tb2, table3 tb3 where tb1.some_col = "some value" and tb2.col_a(+) = tb1.col_a and tb2.col_b(+) = tb3.col_b It depends how you need to outer-join the tables But last time I used outer joins it was in I believe Oracle 8.0.5 Maybe something has changed in 8i, or 9i Witold On 12 Mar 2002 at 5:23, [EMAIL PROTECTED] wrote: > > Hi, > > im trying to create a view comprising of about 10 tables, trying to > join them together.i need a few outer jojns, but i have been told this > is not possible, i.e. having numerous outer joins in the where > clause.. > > anyone got any info on these rules for outer joins? > > cheers > > -- > Please see the official ORACLE-L FAQ: http://www.orafaq.com > -- > Author: > INET: [EMAIL PROTECTED] > > Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 > San Diego, California -- Public Internet access / Mailing Lists > -------------------------------------------------------------------- > To REMOVE yourself from this mailing list, send an E-Mail message to: > [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the > message BODY, include a line containing: UNSUB ORACLE-L (or the name > of mailing list you want to be removed from).
