Hi,
 
i have few question about DTS :
- how to pass  global variable to PL/SQL procedure (when i put "?" as one of arguments - it says -" sql statement does not contain any parameters"

- how to implement  "if/case -logic"
i want to analyze the value of global variable and depending on this value  execute one  or another step ....

- i am executing 10 transformation concurrently and sending success email if all of them succeed, now i need to send a failure email if at least one of these 10 transformations fails. how to do this ?

thanks in advance,
Irina

Using the parameters in SQL tasks is very limited as to what the Designer will allow you to implement.  There are a few workarounds.

First, only pass in the paramter once.  If you have some SQL that needs in in multiple places, do it like follows


Declare @v1 int, @v2 int

Set @v1 = ?
Set @v2 = ?

--- your SLQ, procedure calls using @v1, @v2


To get the designer to accept this code you must trick it.

Get the SQL task to accept your parameter by doing the following

SP_WHO ? --You will need sysntax that will alow you to enter all your parameters in a given order.

After you set your parameter for the above script, paste in your script, with the parameters Declared and set in the same order, and click ok.  It will now run.  I'm going to try and find my answer for this I gave a couple of months ago, it was step by step directions.

The above still goes.  YOu have to trick the driver into thinking you have a parsible SQL Statement--then you can add the parms.

If you need to evaluate the global variable, you probably want to read the global variable in an ActiveX script and then call the PSQL proc from there.

As far as sending failure emails, just put an additional workflow constraint that fires "on failure"....

Add a AxtiveX task, that executes on completion of all steps in question.  Then do and

IF globalvariables.parent.task("SQL...task1").status = ...failure OR exp OR exp THEN
    main.status_fail
ELSE
    main.status_success
END IF


And add your mail task on the failure of this activeX script task.  It will execute if your

I don't have the exact syntax, but you get the idea.

Here's another example of how to trick it into accepting your parameters.

"oh well , the problem is how to trick it ...."

All you have to do is put in a valid Oracle statement that will validate against the data source.  Once you choose the parms you want from the parameter dialog, you can go back and change the PSQL statement to whatever you want (as long as the number of parms  are the same).

thanks guys,

looks like "tricking"  the parser works ...

About "AxtiveX task" - i am SOOO new to this ...
so it i have let's say  2 SQL tasks A and B - (no global  variables are modified there...)

I connect both  A and B to Active X task on completion and then what code  should i put ?

thanks in advance
