Can someone advise me as to the best way to loop through a collection of columns for each row in a table testing the value of each column for nulls etc and then entering the column name into another column where the condition is true..
View 1 RepliesIf I have this table
Mytable
IdnCol ColumnA ColumnB ColumnC ColumnD
1 CC DD EE FF
2 DD GG HH JJ
3 HH JJ KK HH
How I can check for the repeated value in the column.
for example in the 3rd record, in columnA and ColumnD the value HH is repeated
so is there a way to find if there are values repeated in any of the columnA ColumnB ColumnC ColumnD.
Thanks
Hi
I’ve got a simple SQLdataSource which is wired up to a gridView. When the page loads, it’s sometimes likely the data source would contain no data – how can I test for that in the code behind (no data)? I’d like to only show a button if there is data?
I’m using ASP.NET 2.0 with C#
Many thanksRichard
This is the code I'm using to insert data into a table with data from one table, but changing a single column to prevent duplicates and to increase the number of rows. I know I'm missing something easy, but... what is it?
thx,
Kat
code to create the table:
CREATE TABLE [OrdDetails] (
[OrderID] [int] NOT NULL ,
[ProductID] [int] NOT NULL ,
[UnitPrice] [money] NOT NULL ,
[Quantity] [smallint] NOT NULL ,
[Discount] [real] NOT NULL ,
CONSTRAINT [PK_OrdDetails] PRIMARY KEY CLUSTERED
(
[OrderID],
[ProductID]
) ON [PRIMARY]
) ON [PRIMARY]
GO
I inserted all the data from the [Order Details] table, now I'm trying to reinsert the data but changing the PK constraint to prevent error. Seems like this should work.
truncate table OrdDetails
insert into OrdDetails
select * from [Order Details]
/*note, table has 2155 rows to start*/
Declare @CTR INT,
@CTR2 INT
SELECT @CTR = 0
SELECT @CTR2 = 0
WHILE @CTR < 3000 and @CTR2 < 3000
BEGIN
SELECT @CTR = @CTR + 1
SELECT @CTR2 = @CTR2 + 1
INSERT ORDDETAILS
SELECT @CTR, (ProductID + @CTR2) , UnitPrice, Quantity, Discount FROM [Order Details]
END
I still get primary key errors about not being able to insert dups, this is probably easy, but I'm missing something, help!

Can anyone give any advice to finding db files for testing. CSV files or what have you. I want to have some nice fun and repetitive Transact practice in creating db's and users etc. I have seen some online but I wondered first if anyone here used a site in particular that they could recommend. Would be nice to have files that may be standard (csv) and in another db format that I could use, mix it up some.

Hello,
I am looking for a number of concept hierarchies (i.e. hierarchy with is-a relationships) describing the same domain that are accompanied with the instances from which the concept hierarchy was obtained. I have been trying to find some data suitable for representing the extracted knowledge in form of concept hierarchies so that can obtain at least two concept hierarchies from the same domain that differ slightly. In this sense the data needs to have multiple class (target) values and there has to be a hierarchical relationship between the classes. I have looked at the datasets publically available from 'uci' website and some others, but so far it appears that only the Zoo dataset is suitable to be represented in a form of concept hierarchy but it is still closer to a decision tree. I have seen some bird-domain or more specifc animal kingdom hierarchies but I cannot find those more specific datasets. Does anyone know where some concept hierarchies with instances can be obtained or datasets with multiple hierarchically related class values? Any help would be greatly appreciated.
Thanks
I just recently added 30MB of SQL Server database space on my Share hosting account.
I want to put the SQL Web Data Administrator on the server but it is an MSI file and I cannot figure out how to install it.
Also, I will be testing my .Net pages on my local machine. How do I go about it without accessing the SQL Server on my host? I used MS Access before and I have a copy of both databases on my local machine and on the server. I'm thinking of using MSDE on my machine and I just change the connection string when I upload my code. Is this a good idea or is there a better alternative?
Thanks.
We are running Reporting Services 2008 R2 on a Windows Server 2008 Standard 64-Bit server. I have a user that has full access to Reporting Services at all folder levels but IS NOT a local administrator on the 2008 server.
This user can create data source connections but when he tries to test the connection by clicking on the 'Test Connection' button, he gets the following error "The permissions granted to user <username> are insufficient for performing this operation.A user that has administrator priveleges on the server can test the connection fine.
I don't want to make this user an administrator on the server.
This is an extract from the log file:
ibrary!ReportServer_0-24!3478!08/16/2011-13:45:37:: Call to TestConnectForDataSourceDefinitionAction().

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.
Here's another one of my bitchfest about stuff which annoy the *** out of me in SSIS (and no such problems in DTS):
Do you ever wonder how easy it was to set up text file to db transform in DTS - I had no problems at all. In SSIS - 1 spent half a day trying to figure out how to get proper column data types for text file - OF Course MS was brilliant enough to add "Suggest Types" feature to text file connection manager - BUT guess what - it sample ONLY 1000 rows - so I tried to change that number to 50000 and clicked ok - BUT ms changed it to 1000 without me noticing it - SO NO WONDER later on some of datatypes did not match. And boy what a fun it is to change the source columns after you have created a few transforms.
This s**hit just breaks... So a word about Derived Columns - pretty useful feature heh? ITs not f***ing useful if it DELETES SOME of the Code itself after there have been changes in dataflow. I cant say how pissed off im about that SSIS went ahead and deleted columns from flow & messed up derived columns just because the lineageIDs dont match.
Meta-data - it would be useful if you could change it and refresh it - im just sick and tired of it that it shows warnings and errors when there's nothing wrong - so after a change i need to doubleclick all my transforms so that those red & yellow boxes would disappear.
Oh and y I passionately dislike Derived columns - so you create new fields based on some data - you do some stuff - combine multiple columns to one, but you have no way saying remove the columns from the pipeline. Y you need it - well if you have 50K + rows with 30+ columns then its EXTRA useless memory overhead for your package.
Hopefully one day I will understand how SSIS works (not an ez task I say) - I might be able to spend more time on development and less time on my bitchfest - UNTIL then --> Another Day - Another Hassle with SSIS
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
Hello,
i want to import data from an excel sheet into a database. While reading from the excel sheet OleDb automatically guesses the Datatype of each column. My Problem is the first A Column which contains ~240 Lines. 210 Lines are Numbers, the latter 30 do contain strings. When i use this code:
Code BlockDim sConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & conf_path_current & file_to_import & ";Extended Properties=""Excel 8.0;HDR=NO"""
Dim oConn As New OleDb.OleDbConnection(sConn)
Dim cmd1 As New System.Data.OleDb.OleDbCommand("Select * From [Table$]", oConn)
Dim rdr As OleDb.OleDbDataReader = cmd1.ExecuteReader
Do While rdr.Read()
Console.WriteLine(rdr.Item(0)) 'or rdr(0).ToString
Next
it will continue to read the stuff till the String-Lines are coming.
when using Item(0), it just crashes for trying to convert a DBNull to a String, when using rdr(0).ToString() it just gives me no value.
So my question is how to tell OleDB that i want that column to be completly read as String/Varchar?
Thanks for Reading

Hi,
I'm just wondering what's the best approach in Data Flow to convert the following input file format:
Date, Code1, Value1, Code2, Value2
1-Jan-2006, abc1, 20.00, xyz3, 35.00
2-Jan-2006, abc1, 30.00, xyz5, 6.30
into the following output format (to be loaded into a SQL DB):
Date, Code, Value
1-Jan-2006, abc1, 20.00
1-Jan-2006, xyz3, 35.00
2-Jan-2006, abc1, 30.00
2-Jan-2006, xyz5, 6.30
I'm quite new to SSIS, so, I would appreciate detailed steps if possible. Thanks.
Hello:
I am running into an issue with RS2k PDF export.
Case: Exporting Report to PDF/Printing/TIFF
Report: Contains 1 table with 19 Columns. 1 column is static, the other 18 are visible at the users descretion. Report when printed/exported to pdf spans 2 pages naturally, 16 on the first page, 3 on the second, and the column widths have been adjusted to provide a perfect page span .
User A elects to hide two of the columns, and show the rest. The report complies and the viewable version is perfect, the excel export is perfect.. the PDF export on the first page causes every fith column, starting with the last column that was hidden to be expanded to take up additional width. On the spanned page, it renders the first column on that page correctly, then there is a white space gap equal to the width of the hidden columns and then the rest of the cells show with the last column expanded to take up the same width that the original 2 columns were going to take up, plus its width.
We have tried several different settings to see if it helps this issue or makes it worse. So far cangrow/canshrink/keep together have made no impact. It is not possible to increase the page size due to limited page size selection availablility for the client. There are far too many combinations of what the user can elect to show or hide to put together different tables to show and hide on the same report to remove this effect.
Any help or suggestion on this issue would be appreciated
I have a website and database in Access, how do i set it up so i can test it in IIS using SQL server?
View 5 Replies View RelatedHi ,
My Input is a flat file source and it has spaces in few columns in the data . These columns are linked to another table as a foreign key and when i try loading them in a relational structure Foreigh key violation is occuring , is there a standard method to replace these spaces .
what approach should i take so that data gets loaded in a relational structure.
for example
Name Age Salary Address
dsds 23 fghghgh
Salary description level
2345 nnncncn 4
here salary is used in this example , the datatype is char in real scenario
what approach should i take to load the data in with cleansing the spaces in ssis
I am using SqlServer 2005 Express Edition. I have written a stored procedure that has a transaction to make sure that it rolls back in case of failure.

hello everyone i was hoping to get some help.

I want to run remote procs from a local - central proc, but don't want to crash my proc if the remote NT Server or SQL Server is not available.
So, I want to test for NT and SQL availability first.
Here's my code.
====================
DECLARE
@DBName varchar(22),
@QueryString NVARCHAR(130),
@Resultsint,
@ResultsTxtvarchar(31)
/* I find the server-dbasename name in a lookup table, and then build dynamic script */
SELECT @DBName = "<SRVRNAME~DBASENAME>"
SELECT @QueryString = N'master..xp_cmdshell "ECHO >'
+ SUBSTRING(@DBName, 1,6)
+ 'pipesqlquery", no_output'
EXEC @Results = sp_executesql @QueryString
SELECT @Results /* <-- testing here.... */
=====================
If the NT / SQL is running, "@Results" should = 0 (success on the ECHO to the PIPE)
If the NT / SQL is NOT running, "@Results" should = 1 (error on the ECHO to the PIPE)
If I test in QA, I get the expected "@Results" values.
If I run the proc, I get "@Results" = 0 for both events, and them my proc fails on the remote proc call if the NT / SQL is NOT running.
I don't know how to write DMO in TSQL to try that.
I have also tried using 'odbcping' too.
HINTS? Better way to test remote NT / SQL is NOT running?
Thanks in advance.

Has anyone ever heard of using Response.Write to test sql queries in the query designer? Here is the actual suggestion I was given recently:
Response.write your sql query. Copy the query to your db query tool and run the query. Adjust the query as necessary to return the recordset you desire. When you have the proper query, adjust your asp code.
The query editor/designer doesn't like certain symbols and extraneous code. So how exactly can you use Response.Write with a sql query without getting errors in designer?
I've begun some testing with the June beta of SQL 2005. One problemI've hit is with scalar-valued functions. The error I often get whenexecuting functions is "Select statements included within a functioncannot return data to a client.". These same functions are workingfine under SQL 2000.Has anybody seen this behavior or know what the deal is?
