I see two errors

#1) $shiftDate is set to "date" - that's a reserved word - don't use it as a field name.
#2) $shiftLocation is not set, you can see right after etime there is no field name given.

The values are being set in a Perl file.  I cancan change the date but do you see anything wrong with the location?  Thanks

# columns for the shift table.
$shiftID      ="shift_id";            # primary key
$shiftProjID      ="shift_proj_id";      # references the project table id
$shiftDate      ="date";            # date for the shift
$shiftStart      ="stime";            # start time for the shift
$shiftEnd      ="etime";            # end time for the shift
$shiftLocation      ="shift_location";      # location for the shift
$shiftNumPeople      ="num_needed";            # number of people needed
# values are calulated, not stored in the table.
$shiftRegPeople      ="num_registered";      # number of people needed
$shiftStillNeed      ="num_still_need";      # number of people still needed

$shiftLocation is the field I need to add.  thanks

 

by: nemws1Posted on 2009-09-22 at 11:58:57ID: 25396222

Hmm.. no - it looks fine.  But if you look here:

Your query printout:
    "etime text not null, text not null, num_needed integer not null,"

Your error:
    "syntax to use near 'not null, num_needed integer not null, "

That's definitely the problem.

Between lines 3 and 4 of your code, put the following line to see if its getting properly set.

print "Check shift_location:  ==$shiftLocation==\n";

If i run the script again it will clear out the data out of the tables.   I ran a cgi to list the shift table and s location is in there.  I think both my open questions are related to the same thing.

I added the slocation field to the table shift, it's showing up but now I'm having problems accessing it.

I used Alter to the the slocation in the shift table.

Thanks as always!

In the script that executes the SQL, $shiftLocation is not set.  The code you posted will set it, but it appears that the code from your second post isn't being executed before calling the SQL.  Or if it is, then there is some other code that is changing $shiftLocation.

Also note that using variables for field names is very uncommon.  Are you sure this is what you want?
