How to apply paging when fetch large data in Oracle ADF 12.2.1.4.0.
I think we need some config in ViewObject but I don't know how to do that. I cannot find out any introduction about this feature.
In the VO you select the 'General' tab and open the tuning section. There you set the in batches of value to a number which should be bigger than the number of rows you show on the page and select 'Access Mode' as 'Range Paging'.

I currently have a client-server application. The client needs to be able to generate reports. These reports can have millions of records. What is the best way to get the data to the client? Sending all million records at once is not very efficient. Let's say I just want to display 20 at a time and page through all the results. Would I have the server do the query each time a user clicks on next page or should I have the server get the entire result set and then sent parts of it to the client?
Use a cursor - it is perfect for these purposes.
Note - a report with million rows is not well designed report. Nobady can process it. But this is question for analytic.

I used Limit in sql query to set a range of records fetched. but the query has to originate from client and the query must pass the range.
It depends on scripting, if you use Dotnet+npgsql connector
I would generate a Pagenumber in a combobox on form
Then multiply the pagenumber with Rows*(pagenum-1) (20*1 for page2) to get starting rownum
Pass it in form of sql to database
Retrieve rows and display in datagridview
Although, i might just add, searching through a million record Page_by_page is not wisdom. i hope there are some filters to narrow down search to a few pages. Because research show that views beyond page10 drop exponentially.
When I connect Access 2007 to SQL Server (whether by ADO recordset or by linked table) I no longer get check box lists (of available filter values) in the datasheet column filters.
Is this feature available only with MDB/ACCDB and/or DAO?
I think the check box in datasheet view of native Access tables is governed by the "Display Control" property in the table design. I don't recall what's available when the table is in SQL Server. If you provide a form in "datasheet view", you should be able to bind a check box control to the SQL Server column.
Edit: I think I misunderstood your question yesterday. If you click the Office Button, select Current Database, then put a check in the "ODBC fields" box under "Filter lookup options" ... does that do what you want?
I know we're breaking protocol by not opening a new question, but I'm going to answer this nevertheless so this thread will be complete. This is a more complete answer than the previous ones.
I think I have this topic nailed down now.
The lookup filters won't work with a recordsource that is not an Access object, and they don't work in linked tables directly.
You have to create a query of the linked table, for example: Select * from tblOrders, and use that query as the recordsource in order to get the lookup filters.
HOWEVER, I found a more flexible approach as well. I create passthrough queries to SQL/Server and use that as my recordsource. Then, in code, I set the SQL of the passthrough queries like this:
Currentdb.QueryDefs("qpstOrders").SQL="Select * from Orders where OrderID =" & Me.OrderID
In the current event of my subform, I change the query on the fly to pass the appropriate record -- or it can just be a more generic query. The lookup filters work fine this way and the interaction with SQL/Server is lightning fast.
Open the database that you want to optimize.
Click File > Options to open the Access Options dialog box.
In the left pane of the Access Options dialog box, click Current Database.
In the right pane, under Filter lookup options, mark "ODBC Fields" check box.
I would like to edit data directly from result grid in ssms. eg:
When I execute SELECT TOP 10 * FROM some_table, I want to edit data directly from result grid.
I don't want to open some_table and edit from there.
I know that result grid is read-only, but maybe someone written addin for it.
You can't edit the data from within the result grid. You'd have to go via the "open table" route if you want to edit the data manually instead of using UPDATE/INSERT SQL statements.
Is there a reason you specifically want to use the result grid instead?
You can specify a query when you go via open table to limit the results if that's your reason? There's a "Show SQL Pane" button in the top toolbar you need to select (square box with "SQL" written in it).
I have very large database (70+ GB) with so many tables.
I'm using Red Gate's SQL refactor for intellisense and few other things.
It's so boring to type in update sql statements every time I need to change single field.
It also takes some time to find that table in the Object explorer.
Intellisense doesn't work when I use "Show SQL Pane".
I'm new to SQL Server and have used the Oracle product 'PL/SQL developer' by All Round Automations at a previous job... It would allow you to do a SELECT in the query window and then simply add "FOR UPDATE" to the end of your refined SQL SELECT and 'ta-da' you can now edit the results in a nice grid. No need to Open Table View, click the SQL button, paste in the SQL you you have been working on and then hit execute ;)
EMS SQL Manager for SQL Server allows to update data directly inside a results grid.
This tool is boring for typing new requests (poor intellisense and error management) but fine for this. I always have the two tools opened.
If you right click on the table and choose edit top 200 records, it produces a result screen with an query.
Add to this your query and then you can edit the records in the result screen.
Also you can change the 200 to a number you want (2000).
The "results" pane is not just results.
Results in text
Assorted time and IO statistics
Estimated and actual execution plans
Row counts, Error messages, PRINT output
etc
This is why they are separate.
Feel free to write your own add-in :-) Or here
SQL Server ISN'T Access!
When you run a query and get the results - thats exactly what you are doing, reading the data, not opening the table for editing. Can you imagine the necessary transactional control around allowing the results window to be edited? The locking would probably grind SQL to a halt - I hope no-one ever writes that kind of add-in!
I have an Access database that I use to to run a bunch of aggregate TOP 5 queries. The end game of this particular function is ppt presentations with charts. So to automate this a bit, I created an excel spreadsheet with a bunch of pre-made charts in it. The I linked/data imported the query results into the excel spreadsheet, and set the cell ranges to match the source ranges for the charts. Finally I set the spreadsheet to enable auto refresh upon every "file open", and presto, I run the queries in access with a button press, then open the excel file, and the data refreshes, and they are my charts. I then use some VB to copy paste all active charts into ppt, but that is another matter.
Okay so here is the snag I hit. I needed to do the exact same procedure with another spreadsheet from another ag query. Before the process I was using was just clicking data > import external data > import data and then choosing the file of the database, and then it would populate a list of tables and queries to choose from. Only now, it will not show any queries in that populated list; only tables!?!
any ideas? btw MSO 2003
I can't reproduce that Justin. In the dialog that shows the tables, scroll over to the right and check the TYPE column. Queries will have a type of VIEW and tables of TABLE. Verify that they all say TABLE.
Next, try using Data - Import External Data - New Database Query instead of 'Import Data'. Select the Access driver and the Access mdb. This will bring up a different dialog, but should show both tables and queries. See if that shows only tables or shows both.
I presume this is a security feature that has been introduced?
Try selecting any table then select Data>Import External Data>Edit Query
Then select SQL as the command type and either enter the query SQL or just select from a query i.e.:
select * from qryCat;
Hope this helps
thanks Mark
How do I limit a SQL Server Profiler trace to a specific database? I can't see how to filter the trace to not see events for all databases on the instance I connect to.
Under Trace properties > Events Selection tab > select show all columns. Now under column filters, you should see the database name. Enter the database name for the Like section and you should see traces only for that database.
In SQL 2005, you first need to show the Database Name column in your trace. The easiest thing to do is to pick the Tuning template, which has that column added already.
Assuming you have the Tuning template selected, to filter:
Click the "Events Selection" tab
Click the "Column Filters" button
Check Show all Columns (Right Side Down)
Select "DatabaseName", click the plus next to Like in the right-hand pane, and type your database name.
I always save the trace to a table too so I can do LIKE queries on the trace data after the fact.
By experiment I was able to observe this:
When SQL Profiler 2005 or SQL Profiler 2000 is used with database residing in SQLServer 2000 - problem mentioned problem persists, but when SQL Profiler 2005 is used with SQLServer 2005 database, it works perfect!
In Summary, the issue seems to be prevalent in SQLServer 2000 & rectified in SQLServer 2005.
The solution for the issue when dealing with SQLServer 2000 is (as explained by wearejimbo)
Identify the DatabaseID of the database you want to filter by querying the sysdatabases table as below
SELECT *
FROM master..sysdatabases
WHERE name like '%your_db_name%' -- Remove this line to see all databases
ORDER BY dbid
Use the DatabaseID Filter (instead of DatabaseName) in the New Trace window of SQL Profiler 2000
In the Trace Properties go to the Event Selection tab. Then click on the Show All Columns radio button. After that click on the Column Filters button.
Now you can see the Database Name property and click on it. Expand the like box and insert your DB name and click ok and you can run the profiler now.
In the Trace properties, click the Events Selection tab at the top next to General. Then click Column Filters... at the bottom right. You can then select what to filter, such as TextData or DatabaseName.
Expand the Like node and enter your filter with the percentage % signs like %MyDatabaseName% or %TextDataToFilter%. Without the %% signs the filter will not work.
Also, make sure to check the checkbox Exclude rows that do not contain values' If you cannot find the field you are looking to filter such as DatabaseName go to the General tab and change your Template, blank one should contain all the fields.
Create a new template and check DBname. Use that template for your tracefile.
