Morning Joe,
...
In this release it appears that Toad wants me to provide a
value for the same variable every time it used. For instance
I have a query that unions about 10 queries together. The
each are going against the same schema using the same
variable &SCHEMA.
Select *
From $SCHEMA.table1 A,
$SCHEMA.table2 B
...
Is the '$' a typo? It should be an ampersand '&' or two '&&'. Also, I
think you need two dots between the &SCHEMA and the table name:
Select *
From &SCHEMA..table1 A,
&SCHEMA..table2 B
...
Because the first dot tells SQL*Plus/Toad to "stop substitution", as in:
Since this variable is used twice in each query I getting
about 20 SCHEMA values to fill in (SCHEMA(1) through
SCHEMA(20). Older versions such a 9.7.2 correctly
intrpretted that like variables only need to prompted for once.
In SQL*Plus, which Toad emulates to a certain degree, the '&' is used to
prompt for each and every occurrence of a variable (unless it has been
DEFINEd or ACCEPTed first of course) and the '&&' only prompts for the
first occurrence and then uses it again for each subsequent occurrence.
It sounds remarkably like 9.7.2 was broken!
I tried this in 9.5:
SELECT * FROM &SCHEMA..dual
UNION ALL
SELECT * FROM &SCHEMA..dual;
The variables prompt showed two separate variables. When I filled in the
first and clicked OK, I was prompted that "one variable is still empty,
do you want to fix it?".
When I ran it like this:
SELECT * FROM &&SCHEMA..dual
UNION ALL
SELECT * FROM &&SCHEMA..dual;
There was one single variable in the list, and I only received the one
prompt.
Cheers,
Norm. [TeamT]
