Hi,
Below is an Oracle query used for cost optimization purpose :
analyze table test estimate statistics sample 2500 Rows;
Is there any equivalent for the above in SQL Server ?
Please advice,
Thanks,
Sam
Edit 2007-8-9:
Added code to show database file sizes. Not really closely related to tables sizes, but a lot of the people who need this want to know why their database it so large, so it may help to know which files, especially the logs, are so large, and if the files have empty space in them.

-- output from the sp_spaceused stored procedure

Here is a script I wrote that analyzes datasets and returns all the minimal composite and unary keys that uniquely identify records. I wrote it because I frequently have to analyze client spreadsheets and non-normalized data tables.
On my desktop server it took about two minutes to analyze 2000 permutations of a table with 50 columns and 5000 records.
Please try it out for me and let me know if it chokes on anything, or if you see any ways it could be improved!
One of our Oracle Tables changed and I am wondering if there's any way that I can query all of our Stored Procedures to try and find out if that Oracle Table Name is referenced in any of our SQL Server Stored Procedures OPENQUERY statements?
View 2 Replies View RelatedHi Everyone,
I've been searching for a solution for this for a week-ish, so I thought I would post my quesiton directly. Here is my scenario..
Source: MS SQL Server
Destination: Oracle 10g
The destination table has a partition set on a column called "DATE_HIGH". How do I populate this date high column in my package? Currently I just have a source object, and a destination object, but I'm unclear how to populate this field in the destination. I've read one blog that states "use OLE DB Command" - but that isn't enough information for me to implement - Can someone be more specific in these steps? Here is an example of what my newb-ness needs to understand
OLE DB Source (Select * from Table) ---> OLE DB Command (What query goes here?) --> OLE DB Destination.
Second part of my question: There is a second column called "ROW_NUM" and there is an Oracle Sequence provided to me... What objects do I need (Source, Destination, OLE DB Command etc...) and how do I call this sequence to populate on the fly as I'm loading data from my source?
If these are simple questions - my appologies, I am new to the product.
Best Regards,
Steve Collins
Oracle and MS drivers do not support parameterized queries, so update table set column=? where primarykey=? does not work for Oracle.
Anyone knows how to update an Oracle table through SSIS?
Thanks!

Hi Guys, I am trying to manipulate an SQL statement based on the return from a menu with auto postback enabled.Simply I am working with dates, so I will declare variables for today, next week, last week and so on.How do I then use this in the SQL? I assumed that if I declared the following Dim my_today As String = Format(Date.Now(), "dd/MMM/yyyy")Then in the SQL I used SELECT * FROM my_table item_date = @my_todayI would get a result, but I get an error. What is the right way to do this? Many thanksSteve

I have been asked to analyze a DB which was under a different team. I have done the following,
1.Identified tables without PK, and clustered index
2.identified FK’s without index
3.orphan users and weak passwords
4.analyzed SPS for bad code
Is there anything else I can do? Are there any ready-made scripts which I can use.

Hello, friends!
sorry for the stupid question:
I created a new index on table and I'm looking to a command equal to "Analyze table ", "Compute statistics "in Oracle
to check if that index is usefull.
Thank you very much in advance.

View 1 Replies View RelatedI will be grateful if you could answer a few more questions around Analyzing Key Influencers
1. When specifying the training data for Decision Tree, there is a SUGGEST button (Recommend inputs for currently set predictable) which recommends which input are related to the predictable attribute. It also gives a €˜Score€™ for each recommended inputs. What algorithm does the SUGGEST button use? Does it use simple entropy/correlation based algorithm OR sophisticated feature selection algorithms?
2. Can I access this €˜Score€™ and recommended inputs above programmatically?
3. What feature selection algorithms are used in SQL Server 2005? Can they be invoked programmatically?
5. In Logistic Regression mining model viewer, we get a chart which clearly shows what attributes favor which state of the predictable attribute. For example, income level < 23000 favors BikeBuyer = 0 (does not buy) with a score of 89.00. What algorithm is used to calculate the €˜Score€™? Can LR be used as a feature selector in case where the predicted attribute is binary (select the attributes that favor one state or the other with a score of, say, greater than some threshold)?
6. You suggested using Naive Bayes to find AKIs. What if the input attributes are all continuous (predicted attribute binary)? Shouldnt I be going for LR?
Thanks bunches

Hi, the other day, some data was deleted by mistake, the data that we wanted to delete was in just 1 table, and we deleted the related data in a couple tables more...
We do full backups every Sunday and a Differential every day, my question is:
Is there any way to analyze the backup file to compare the backed up data with the data that the table has now, and by automatic means restore just some rows to the table, or at least see the data to insert it manually?

Msg 245, Level 16, State 1, Procedure CompactL1RecordsFromfirstINTRAD, Line 177
Conversion failed when converting the varchar value
'DECLARE rows_cursor CURSOR FOR
SELECT ask, dateTimed FROM iDay_Compr_GOOG
WHERE DAY (dateTimed) = ' to data type int.
I get this message while executing a stored procedure. It works "half way" but skips this statement and the whole block as a result. In the table @table_name ask is declared as float and dateTimed as DateTime. Similar statements work happily in other stored procedures with no problem. Even in the same stored procedure I have places where I use DAY (dateTimed) and they seem to work as far as I can see although it is a very branched out code with many IF ... ELSE's.
SET @SQL = 'DECLARE rows_cursor CURSOR FOR
SELECT ask, dateTimed FROM '+@table_name+'
WHERE DAY (dateTimed) = '+@day+' AND NOT ask = 0'
exec sp_sqlexec @SQL
OPEN rows_cursor
FETCH LAST FROM rows_cursor INTO @askQ, @lastTableDateTime
SET @SQL = 'UPDATE '+@table_name+' SET askSize = askSize + '+@askSize+'
WHERE dateTimed = '+@lastTableDateTime+' AND ask = '+@askQ
exec sp_sqlexec @SQL -- <== this is line 177
CLOSE rows_cursor
DEALLOCATE rows_cursor
Another puzzle for me is the line number. I used Edit-->GO TO--> 177 to single the line out and it seems to point to a different exec sp_execsql @SQL statement, the one that is down the road.
I can make neither head nor tail out of it. I am sure Jens, Cetin or Andrea or whoever stumble on this post will be able to figure this out. Anyone else's help will also be appreciated.
Many thanks.
I have installed SP2 on my laptop and I have installed the latest Data Mining Add-Ins.
When I open the sample spreadsheet and select the table in a worksheet called "Table Analysis Tools Sample", I dont get Analyze ribbon under Table Tools. Is ther any reson for it?

I would like to find out how to capture record count for a table in oracle using SSIS and then writing that value in a SQL Server table.
I understand that I can use a variable to accomplish this task. Well first issue I run into is that what import statement do I need to use in the design script section of Script Task. I see that in many examples following statement is used for SQL Server databases:
Imports System.Data.SqlClient
Which Import statement I need to use to for Oracle database. I am using a OLE DB Connection.
any idea?

I have installed the excel DM addin and am trying to work through the tutorials -
When I run the 'Analyze Key Influencers' tool against the sample data through a remote AS server I get:
The task was not able to detect any key influencers for the 'Purchased Bike' column. The values of 'Purchased Bike' seem unrelated to values of other columns.
however when I run it against a local AS server I get the expected results.
I can see no differences in settings or setup between the AS instances I am trying to use - perhaps a permissions issue?
Thank you

Hi all,
I am querying a table in oracle, the server connection to the Oracle database is determined by a criteria. Though how can I put the results from the oracle query into a temp table ?
This is the code i'm using for the query:
DECLARE @cmd VARCHAR(500)
declare @Year varchar(25)
set @Year = '2006'
DECLARE @Link VARCHAR(100)
DECLARE @Table VARCHAR(100)
select @Link = Server from tbl_Conn where Area='Floor'
select @Table = Target_Table from tbl_Conn where Area='Floor'
SET @cmd =
'
select * from OPENQUERY
(
' + @Link + ',
''
UPDATE '+ @Table +'
SET TARGET_VALUE = '+@Value+'
WHERE Date = '+@Year'
''
)
'
EXEC (@cmd)
How do I put the executed results into a TEMP table ?
Rgds,
I'm having a problem with DTS.
I've got a table on a Microsoft SQL 2000 server that I'm attempting to export to an Oracle Table.
The Oracle Table has a Primary key set, that automatically generates it's own keys.
However, using the DTS export job I continually get:
------------------
Error Source: Microsoft Data Transformation Services (DTS) Data Pump
Error Description:Insert error, column 1 ('INPT_PKT_HDR_ID', DBTYPE_NUMERIC), status 10: Integrity violation; attempt to insert NULL data or data which violates constraints.
Error Help File:sqldts80.hlp
Error Help Context ID:30702
------------------
Now, I'm not attempting to insert anything into this primary key field, so why oh why am I getting this error message?
I'm using a DTS ActiveX Script to do the transformation as follows:
------------------
'************************************************* *****
' Visual Basic Transformation Script
' Copy each source column to the
' destination column
'************************************************* *****
Function Main()
DTSDestination("PKT_CTRL_NBR") = DTSSource("PKT_CTRL_NBR")
DTSDestination("CUST_RTE") = DTSSource("CUST_RTE")
Main = DTSTransformStat_OK
End Function
------------------
So nothing too scarry or difficult there.
I'm using an ODBC Oracle connection to the get to the Oracle table, although I've also tried using the Microsoft OLE DB Provider for Oracle.
Both give me the same error.
Importing data from Oracle to Oracle works.
Can someone please suggest some ideas to fix this problem?
Thanks.

We are using the whole BI-package from Microsoft - from SQL, DTS-package,Raporting Service and Analyze Service.
It should be very helpful to be able to create a metadata databases where you could find all releations between different objects (tables,views,reports,cubes,DTS-package,Databases.
Just to get answer for: 'where is view xxx used', 'what are Report xxx depending upon'.
While everything exists in different SQL databases it should possible to do.
Has anyone any comments or the same needs ?
