I want to check one procedure where it is being called ?
Is there any way for his ?
i have tried to generate using db2look but it didnt work .
You can use the sqlpltrc and the SQL profiler utilities. There are few articles about that, but they can help to have stack call of your procedures.

Another way to that, is to look in the TEXT column of the SYSCAT.PROCEDURES view, looking for the name of your procedures. However, if there is dynamic SQL, this could eventually not help. Also, if any function or trigger calls you SP, you need to look for the name in the corresponding tables.

I have been using PostgreSQL for the past few weeks and I have been loving it!
I use crypt() and gen_salt() to generate the password hashes, by adding it to the insert query like so:
crypt(:password, gen_salt('bf', 8))
Likewise for the select I use something like:
crypt(:password, u.password)
I want to simplify my SQL code by automating the hash on the table's password column, instead of the SQL queries or additional functions.
To be more clear, when I insert a row in the table, I want it to convert hash/compare immediately.
Is there a way? And if yes, would that be wise?
I won't comment on the "would that be wise?" part of the question (not because I think it's unwise, but because I don't know enough about your needs).
If you want to automatically compute a column value during an INSERT or UPDATE, you need a trigger (see CREATE TRIGGER).
If you want to automatically compute a column value during a SELECT, you need a view (see CREATE VIEW).
There are other ways to achieve what you ask, but triggers and views are probably the most straightforward mechanisms.
I have a stored procedure in my project under sql/my_prod.sql
there I have my function delete_entity
In my entity
#NamedNativeQuery(name = "delete_entity_prod",
query = "{call /sql/delete_entity(:lineId)}",
and I call it
Query query = entityManager.createNamedQuery("delete_entity_prod")
setParameter("lineId",lineId);
I followed this example: http://objectopia.com/2009/06/26/calling-stored-procedures-in-jpa/
but it does not execute the delete and it does not send any error.
I haven't found clear information about this, am I missing something? Maybe I need to load the my_prod.sql first? But how?
JPA 2.1 standardized stored procedure support if you are able to use it, with examples here http://en.wikibooks.org/wiki/Java_Persistence/Advanced_Topics#Stored_Procedures
This is actually they way you create a query.
Query query = entityManager.createNamedQuery("delete_entity_prod")
setParameter("lineId",lineId);
To call it you must execute:
query.executeUpdate();
Of course, the DB must already contain the procedure. So if you have it defined in your SQL file, have a look at Executing SQL Statements from a Text File(this is for MySQL but other database systems use a similar approach to execute scripts)
There is no error shown because query is not executed at any point - just instance of Query is created. Query can be executed by calling executeUpdate:
query.executeUpdate();
Then next problem will arise: Writing some stored procedures to file is not enough - procedures live in database, not in files. So next thing to do is to check that there is correct script to create stored procedure in hands (maybe that is currently content of sql/my_prod.sql) and then use that to create procedure via database client.
All JPA implementations do not support calling stored procedures, but I assume Hibernate is used under the hood, because that is also used in linked tutorial.
It can be the case that current
{call /sql/delete_entity(:lineId)}
is right syntax for calling stored procedure in your database. It looks rather suspicious because of /sql/. If it turns out that this is incorrect syntax, then:
Consult manual for correct syntax
Test via client
Use that as a value of query attribute in NamedNativeQuery annotation.
All that with combination MySQL+Hibernate is explained for example here.
The question pretty much sums it up. I've got to replace text in a large number for store procedures. Its not so many that doing it manually is impossible, but enough that I'm asking the question. I also prefer automation as it reduces the change of user error when we make the change in production.
I can Identify them like this:
select OBJECT_DEFINITION(object_id), *
from sys.procedures
where OBJECT_DEFINITION(object_id) like '%''MyExampleLiteral''%'
order by name
Is there any way to mass update them all to change 'MyExampleLiteral' to 'MyOtherExampleLiteral'?
I'd even settle for a way to open all the stored procs. Just Finding these store procs in a larger list will take some time.
I thought about generating alter statements using the above select statements, but then I lose line breaks.
Thanks in advance,
This is a Microsoft SQL Server.
There are different tools to use depending on the database in question. For example, Microsoft SQL Server Data Tools integrates with Visual Studio, and allows you to do these types of operations fairly easily. The database is stored in your solution as scripts, which you can then search and replace any keyword you wish. I'm assuming there would be similar tools available for other platforms.
You could do this with dynamic sql. Query the system tables to get all the SPs containing your "MyExampleLiteral":
SELECT [object_id] FROM sys.objects o
WHERE type_desc = 'SQL_STORED_PROCEDURE'
AND is_ms_shipped = 0
AND OBJECT_DEFINITION(o.[object_id]) LIKE '%<search string>%'
Then, write a while loop to go through those object_ids. In the while loop, get the OBJECT_DEFINITION() into a string and replace the "MyExampleLiteral", then replace CREATE PROCEDURE with ALTER PROCEDURE and execute the string using sp_executesql.
Doing something this crazy, make sure you backup the database first.
Hello all,
I want to execute the following procedure:
EXECUTE MYDB.dbo.MYPROCEDURE
#gender='male',
#status='single'
The status can be single, divorced or married.
I need to execute the procedure having all the males that are single and divorced.
Ho can I do that?
Thanks a lot
The best way to do this would be to change your stored procedure over to a table-value function. Then you could call it twice and UNION ALL the results to get one resultset. The other way to do it would be to just call the stored procedure twice and add the results together yourself.
Unless you are fine with getting two resultsets back (by executing the statement twice), you will need to make some sort of modification to your SQL statement.
That's just not possible unless you rewrite the procedure
This is not possible without changing the Procedure.
One option would be to set the value as singledivorced and have the following WHERE clause:
WHERE [status]=#status
OR (#status='singledivorced' AND ([status]='single' or [status]='divorced'))
I have a temporary table (or, say, a function which returns a table of values).
I want to execute some statements for each record in the table.
Can this be done without using cursors?
I'm not opposed to cursors, but would like a more elegant syntax\way of doing it.
Something like this randomly made-up syntax:
for (select A,B from #temp) exec DoSomething A,B
I'm using Sql Server 2005.
I dont think what you want to to is that easy.
What i have found is that you can create a scalar function taking the arguments A and B and then from within the function execute an Extended Stored Procedure. This might achieve what you want to do, but it seems that this might make the code even more complex.
I think for readibility and maintainability, you should stick to the CURSOR implementation.
I would look into changing the stored proc so that it can work against a set of data rather than a single row input.
Would CROSS/OUTER APPLY do what you want if you need RBAR processing.
It's elegant, but depends on what processing you need to do
