Hi,
I try to select data from a table with NULL value in, within a
C program.
I declare a cursor with ECPG ("exec sql declare mycursor
cursor for select mycolomn from mytable").
Each time I execute a fetch command, I got an error message
"NULL value without indicator".
I search in the archive

Yes, you must (there is no ODBC driver version > 6.5 for win, I think)

The check constraint is going to be evaluated *before* the proposed
new tuple is inserted into the table, not after; so doing a select

Uhhh. I get no errors, but it dosen't work, either. Consider:

END;

thank you very much!
But I can tar the old database ,if there is another way to move the datebase , please
tell me or please tell me about your way detailed,thank you !

Someone else ran into that just a few days ago. Looks to me like you're

Right. Pushing the SELECT into a SQL or PLPGSQL function that's called
by the constraint is a good workaround, ie
CHECK (testconstraint(a, b))
where FUNCTION testconstraint(a int

So, I

Hi,
I have take a look to the source code concerning PL/Perl, it seems that 2 variables
have a bad call : errgv and na.
If you replace them by their normal call (in 5.6.0) PL_errgv and PL_na you will get

Also in Perl documentation you will find the answer f

Hi,
Ive a SELECT cursor which I want to update/delete but postgresql does not
support these:
UPDATE myTable SET myColumn = 'myValue' WHERE CURRENT OF myCursor
DELETE myTable WHERE CURRENT OF myCursor
Does there exist any workaround?

One workaround would be to get the row
