BTW, Sybase/SQLServer:
 x *= y
in Oracle is:
 (+) x = y
but I can never remember which side is outer without Googling, probably x as
the plus is mnemonic for 'add rows when I am missing'.  I usually use the
ANSI join, which should be supported, is more explicit and much more
portable.

Subject: [freetds] LEFT OUTER JOIN fails on Oracle database


Hi,

 

FreeTds Version = 0.63 (tds version = 8.0)

SQL Server version = 2000

Client = Solaris 2.9 / Oracle 9iR2

 

Running the following SQL from the Oracle database connecting to SQL
Server 2000 fails with ORA-00997: illegal use of LONG datatype.

 

Select c.ref1, c.col

>From tab1 c

Left outer join tab2@databaselink e on e.ref1 = c.ref1;

 

The column ref1 is of type INT on both tab1 and tab2 tables. By
selecting the data_type from dba_tab_columns on oracle, the data type is
confirmed to be NUMBER - therefore the data type conversion appears to
work fine.

 

Additionally, I am able to complete a normal join between the two tables
successfully, e.g.

 

 Select c.ref1, c.col

>From tab1 c,tab2 e

where e.ref1 = c.ref1;

 

I believe SQL Server supports the ANSI left outer join syntax (I have
tried the Sybase *=, but Oracle can not interpret).

 

Does FreeTds support the left outer join operation? Has anyone
experience of this particular error?

 

Regards,

Ian.
