Re: a stored procedure ..with integer as the parameter

Title: Re: a stored procedure ..with integer as the parameter

from the client i receive a vector of strings ...which i have to pass as arguments to the stored procedure.

 

That stored procedure has valid arguments data types

 

for instance

i have a stored procedure as follows:

 

insert(integer, varchar(256), smallint)

 

from the client I get : "200", "surabhi", "10"

 

now i have to make a call to the stored procedure using the above received strings.

 

will not the "200" be converted to a valid integer before saving into the database ..and same with the smallint values.

 

thanks,

regards

Surabhi

Don't try to use an empty string as an integer?

Seriously, you need to give information about what you want to happen,
because an empty string isn't a valid integer and can't really be
converted into one (we explicitly removed code that handled this case
because we thought it didn't make sense).
