Read From Another Column
Oct 3, 2014
I have a table called TblCustomer. It has many columns but for this exercise I will ONLY take the first 2 columns relevant to this problem..
Customer ID Supplier ID
20001
20001
20465
20566
20566
Now, I want on record load it populates the Customer ID as incremental for that supplier ONLy, therefore, the result will be
Customer ID Supplier ID
120001 20001
220001 20001
120465 20465
120566 20566
220566 20566
320566 20566
So as you can see, I am incrementing the first digit ONLY if the supplier ID is the same, otherwise, I start again at 1 for the next customer ID and so on.
Now, how can I achieve this in SQL database.

Hi,
I'm connecting to my SQL Server via Java in my Notes environment, but when I try to update my Notes-documents I get an error fra SQL Server saying that it can not re-read data from column 2.
Without being absolutely certain - I'm quite sure that the code is valid.
Does anyone know what the error means ?
Thanks in advance

Hi!
We currently have a problem while reading Excel files. The file has one column we want to read as DT_(W)STR which Jet delivers to us only as DT_R8 as there are plenty of numerical entries in that column before one alphanumerical appears.
We first tried with IMEX=1 but as described in http://support.microsoft.com/kb/194124/en-us will only parse the first eigth characters as "TypeGuessRows" is set to 8 and can't be edited.
Is there any way to read a column in Excel in a way typed by the SSIS designer (DT_(w)STR in our case)?
With best regards,
Hauke Schlichting
PS: Designing a "decoy" Excel file with column headers and first columns set is not really considered an option ;-)

Hi folks, I have a little challenge for you, I hope :)
The short story is as follows: I have multiple rather well normalized tables, and a view which connect them all togheter. In one of the tables I have an xml column, which I in the view to varchar(4000), since SSIS doesn't like xml all that much. To make the view updateable I have an instead of trigger placed on it, which works quite perfectly from T-SQL. SSIS however, claims that I cannot insert to a read-only column. Does anyone have the slightest idea how I can get around this?
The only solution I can think of is having two columns for the XML data, one as varchar and the other as varchar, then having a trigger updating the xml column when the varchar is updated, but that would require recursive triggers, which I am not too happy with.
Cheers

The below query will read the data in XML format but any query to read from each column of XML tags easily?
SELECT CAST(record AS XML), record
FROM sys.dm_os_ring_buffers

Hi,
I have a package that reads a fixed width flat file data into a single CHAR column in an sql server 2005 table.
In the "Columns" tab of the Flat File Connection Manager, I set the RowDelimiter value to {LF} and nothing for the ColumnDelimiter (since I read the entire row from the flat file into a single column in my sql table).
However, in the "Advanced" tab, the ColumnDelimiter Misc property shows {LF}. This was working fine for me.
The problem I was facing was with some files which were recently identified to have rows containing a special character (probably ASCII ZERO) in the middle of the row. So, now if the record was having 400 characters and the 200 th character had this special character, the package was writing the first 200 characters into the sql table and ignoring the rest of the characters.
I am sure that the special character was ASCII ZERO - I wrote a script to read each character in the line and find the ascii code for it.
Has anyone faced this problem ever. If so, pls let me know your solution or any ideas that can help sort this problem. Your help would be much appreciated.
Thanks!!

I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?

i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?

OK, I'm using VS2003 and I'm having trouble. The page works perfectly when I created it with WebMatrix but I want to learn more about creating code behind pages and this page doesn't work. I think it has some things to do with Query builder but I can't seem to get change outside "please register". I have the table populated and it is not coming back with "login successful" or "password wrong" when I've entered correct information. Enclosed is what I've done in VS2003. Can you see where my error is? Any help would be greatly appreciated.
Thanks again.

Hi!
I have a table like this below and it doesn't only contain English Names but it also contain Chinese Name.
CREATE TABLE Names
(FirstName NVARCHAR (50),
LastName NVARCHAR (50));
I tried to view the column using SQL Query Analyzer, It didn't display Chinese Character.
I know that SQL Server 2005 is using UCS-2 Encoding and Chinese Character uses Double Byte Character Set (DBCS) Encoding.
I want to read the FirstName and LastName columns and display in Window Form Data Grid and ASP.NET Grid View.
I tried to use this code below and it didn't work. It convert some of the English Name to Chinese Character and it display the chinese character and some still in the original unreadable characters.
Does anybody know how to read those character from SQL Table and display the correct Chinese Character without converting the English Name into Chinese also?
Thanks
int codePage = 950;
StringBuilder message = new StringBuilder();
Encoding targetEncoding = Encoding.GetEncoding(codePage);
byte[] encodedChars= targetEncoding.GetBytes(str);
.
message.AppendLine("Byte representation of '" + str + "' in Code Page '" + codePage + "':");
for (int i = 0; i < encodedChars.Length; i++)
{
message.Append("Byte " + i + ": " + encodedChars);
}
message.AppendLine(" RESULT : " + System.Text.Encoding.Unicode.GetString(encodedChars));
Console.Writeline(message.ToString());

Hi all,
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.
any workarounds for this ?

Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]
[Name]
[RowID Table Level]

and I need to change the column type for the columns:
[RowID Table Level]
[RowID Data Level]
to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time.
What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below:

I have tried the code below, but getting syntax error...
ALTER TABLE #CTE
ALTER COLUMN

[RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE
MODIFY

The new databound controls are great, but somehow doing the simpler things has gotten harder.The code is in a function that is passed pollid. I want to use SqlDataSource to get the smallest value of answerid where pollid = the value passed for pollid. For example:"Select top from PollAsnwers where pollid=" & PollId & " order by AnswerId" I can set up the SqlDataSource for a data reader to fill a GridView control, but that isn't what I want to do. In fact, I can't find anything on SqlDataSource that doesn't also involve the GridView control.I have so far:Dim myConnection As SqlConnectionDim myCommand As SqlCommandDim myReader As SqlDataReadermyConnection = New SqlConnection()myConnection.ConnectionString = ConfigurationManager.ConnectionStrings("UserPolls").ConnectionStringmyCommand = New SqlCommand()myCommand.CommandText = "Select top from PollAsnwers where pollid=" & PollId & " order by AnswerId"myCommand.CommandType = CommandType.TextmyCommand.Connection = myConnectionmyCommand.Connection.Open() Now assuming I have a single row of data, how do I read the value of Answerid? If I have this wrong, what should I have? Diane

Hey ,
I have sql server 2000, and i am using Microsoft Application block.
I have Transaction Like...
SqlConnection conn = new SqlConnection(ASLConnectionString); conn.Open(); SqlTransaction Trans = conn.BeginTransaction(IsolationLevel.ReadUncommitted);
But If i have another process that try to read the Table if that old transaction running.. it wouldn't Allow me to read the DATA.
i tried Isolation level "snapshot" but that works under sql server 2005 only. so i can not use that. And i have some services that will run during day time.
So if anybody have solution to read the data from table...from sql server 2000 even if another transaction is running?
Please Give any guideline..Help will be appriciated.
thanks & regards,
