Bind_param_inout stored procedure
I don't know Oracle, only perl, and I need to write a script that calls an Oracle function. I'm not sure how to call a function as opposed to an sql query. Here's the connect part of the code All modules are installed and working.. That is good news indeed!! The first input param is hard-coded, while the 2nd is obtained from a PERL variable.
The 3rd param Your stored proc may or may not accept input params. And what does the 50 do? I really appreciate your help You can enter in any sequence. If the value returned from the database is too big to fit, then the execution should fail. If unsure what value to use, pick a generous length, i. The only cost of using a larger value than needed is wasted memory.
Thanks maneshr, The stored procedure itself is not working, so I will assume that the code you gave me is fine and award you the points.
If I need any further help I will repost and offer additional points. Thank you VERY much!

I would like to receive news, updates and offers from Experts Exchange. Email validation using Regular Expression in Perl.
This code is self explainable except that Regular Expression which I used for pattern matching. I originally published as a thread on my website: In the distant past last year I hacked together a little toy that would allow a couple of Manager types to query, preview, and extract data from a number of MongoDB instances, to their tool of choice: Validation of Email Addresses with Regular Expressions.
You can pass parameters to the subroutines You can use both positional and named parameters if the database you are using supports them , but cannot mix the two styles in the same call. Positional parameters are passed in after the database handle, which is always the first parameter:. The parameters you use have to match the parameters defined in the database for the stored procedure. If they do not, you will get a database error at runtime.
You can also use OUT and INOUT parameters, which return values from the stored procedure, by setting up a scalar variable to receive the result and passing a reference to that variable:. You might need to specify additional options for DBI to know how to bind these variables. You can do so by wrapping the variable reference and the options in an arrayref:. Above code results in.
If you do not specify options, the parameters will be bound with a default maximum size of bytes. A few attributes are independent of the database system that you use, but most rely on specific functions of the DBMS implemention. Please see the documentation about the DBMS you are going to use:. See the DBI documentation on how this works. Some stored procedures can return a result set this topic is covered in the DBMS-specific documentation.
Check the DBI documents for details. Having to pass in the database handle as a parameter is a little ugly. If you put your wrapper subroutines into a package you can use the following syntax. You are still passing the handle around, but it is visually separated from the "real" parameters. If you do not want to import wrapper functions, you can still use the SQL generation and parameter binding mechanism of DBIx:: You can also use attributes except for: You have to read the DBIx:: ProcedureCall documentation for the database system that you are using:.
