问题 I am attempting to execute a stored procedure from Spring Batch, the stored procedure has two parameters, an IN parameter and OUT parameter. What I want is to get the result set and the out parameter when the stored procedure is called. I referred to StoredProcedureItemReader and StoredProcedureItemReaderBuilder I can use this to call a stored procedure that has only IN parameter, however, I can't call after registering OUT parameter.

问题 I'm calling stored procedure from java. Now I need to set the stored procedure's parameter by its name instead of its position inidex, is it doable?

I would like to be able to debug these java procedures, with a same debug methodology like setting the App server in Debug mode. is it possible? how can I do that? Thanks 回答1: I think you'll want to use JDeveloper which you can also use to debug the app server. It's not as good an IDE as, well, almost any other IDE, but it works well enough for debugging tasks. 回答2: The Oracle JDeveloper has support

问题 I have a java stored procedure that I am trying to insert a byte[] array into an oracle blob field in a table. I create a prepared statement as follows but it will randomly fail when I execute the prepared statement. I have narrowed down that the issue is coming from the pstmt.setBytes(4,content).

问题 Can anyone explain why was idea to store Java class in Db? What it is good for? And how to create stored procedure with Java class? Best regards! 回答1: Oracle introduced stored procedures into their database in release 8i. The i stood for "internet", as in "internet-ready", which basically was a bit of marketing.

问题 I asked a similar question the other day but have since realized I was getting ahead of myself. I'm seeking advice on the proper way to handle the following scenario. I'm trying to SELECT the correct longitude and latitude for a given address and city, in the fastest way possible. My COORDINATES table has 25,000 rows and looks like this: I have a Java HashMap<Integer, List<String>> which contains an Integer as the key, and an ArrayList containing 2 entries, an address and city.
