I have a requirement like this. I have set of applications (application is a java object). Every application has a set of fields (Field is a java object). Every field has set of attributes. I need to store multiple fields for a specified application at one go.
I have a stored procedure with following signature.
Where FIELDS_TYP is an OBJECT defined as follows. [I removed and renamed some of the fields to make it simple]
This stored procedure can take list of field objects in single invocation.
How should invoke this stored procedure with a list of field objects from java code in single invocation using Spring 3 JDBC module. I am not using any of the ORM tools.
Note: Since I want to write a generic code, I am not supposed to use any of the database specific APIs like ARRAY from Oracle.
I have read the documentation, but I didn't completely understand. There is very little information in the documentation about calling stored procedure with list of objects.
But, now my problem is resolved after going though one of your links and the spring documentation together. I could not do it anyway without Oracle's ARRAY and STRUCT types.
What I have actually done is, I created STRUCT object for each set of input values and kept them in ARRAY object and passed this ARRAY object to stored procedure. Now it worked.
For anyone's reference, I am posting complete working code below.
