问题 I know the preferred method for returning scalar values from stored procs is either using RETURN or an OUTPUT parameter. But lets say that I have a stored proc that returns the value using a select statement: CREATE PROC spReturnNumber AS SELECT 1 Is it possible to get this value from within another stored proc? CREATE PROC spCheckNumber AS EXEC spReturnNumber -- <-- get the return value here? Clarification: I need a solution that doesn't require using an OUTPUT parameter, or using RETURN to

问题 I have found a few articles like this one: http://devtoolshed.com/using-stored-procedures-entity-framework-scalar-return-values Yet when I take the step to create a function import for a int32 scalar, this is what gets generated: public ObjectResult<Nullable<global::System.Int32>> MyStoredProcedure(Nullable<global::System.Int32> orderId) { ObjectParameter orderIdParameter; if (orderId.HasValue) { orderIdParameter = new ObjectParameter("OrderId", orderId); } else { orderIdParameter = new

问题 We have a table with a Primary Key that gets populated on insert by a trigger on the table - the trigger gets the next sequence number from a sequence we created for the table and uses that for the value of the key on insert.

I have been googling all day and basically come up with nothing - anyone been successful with this before? Thanks 回答1: I don't know if it

问题 I want a script which will show the dependencies of stored procedure in database. Actually when we manually do view dependency it will take a lot of time I have more than 500 stored procedures.

EXEC sp_depends

问题 From what I've read it should be possible to edit data described by a view if the data being modified represents only one table and a unique identifier field is included in the data. According to Microsoft Any modifications must reference columns from only one base table Has anyone had any luck creating an MS-Access form that is editable when the underlying recordset is based on a view or stored procedure merging data from two tables? My form only used the secondary table to join a code table
