Re: [QF-Test] Using a generic procedure for SQL UPDATE and INSERT where number of elements is variable.

Hi,

you can make such procedures dynamic.

Let's say you specify a procedure with the parameters:

column1 = col1
value1 = val1
column2 = col2
value2 = val2
etc.

Then your procedure could contain a script building the SQL statement
like this:

Server script (Jython):

maxVars = 100
dbUpdateCall_Part1 = "insert into table values("
cols = []
values = []
for i in range(1,maxVars):
    try:
        column = rc.lookup("column" + str(i))
        value = rc.lookup("value" + str(i))
        if column:
            cols.append(column)
            values.append(value)
    except:
        break

fullCall = dbUpdateCall_Part1
for col in cols:
    fullCall = fullCall + col + ","

#:-1 should delete the last comma which is too much
fullCall = fullCall[:-1] + ") VALUES ("

for val in values:
    fullCall = fullCall + "'" + val + "',"

#:-1 should delete the last comma which is too much
fullCall = fullCall[:-1] + ")"

#print "Full Call", fullCall
rc.setLocal("fullDBCall", fullCall)


--> At end the variable "fullDBCall" should contain a command like:

insert into table values(column1,column2) values ('val1','val2')

Then put that call to a procedure call of
"qfs.database.executeStatement" and send the statement to your database.


As you can see in the script above, you can specify at maximumum 100
columnX and valueX pairs, which will be treated in the for loop.


Best Regards,
Martin

Happy Friday, everyone.

In a number of recent automation scripts we’ve been requested to create,
text information on the screen is fetched and written to a SQL table. In
the past, we had 4 text elements we read per page, and created a generic
INSERT INTO procedure that listed 4 columns and 4 variables. We have a
similar one that does UPDATE as well.

My current project has one page that has 5 text elements to a single
record, another page that has three, another that has 10. Another
project has similar variety.

Can I write a generic database procedure that will allow me to assign
the necessary columns at the specific test procedure call? So far it
only allows what I explicitly write the SQL to be. If I specify 4
columns and 4 values, it has to be 4 in the procedure call.

Or do I just have to accept that I will write separate statements for
each page as needed, or write three generics (three columns, two
columns, 1 column) and repeatedly call as many as needed to get the
desired number of UPDATE or INSERTs?

I’m really new at SQL so if there’s an obvious query solution, please
don’t judge too harshly J

Thanks in advance, have a good weekend.
