Hey guys :)
First, im sorry for my English - I'm really trying! :D
I started using ASP.NET with Visual Web Developer for about 2 weeks ago, so im still very new to it. Before the I started with ASP.NET, I used classic ASP and now I really miss it :D
My problem is that I'm trying to make my own login-system. Creating users with detailsView to my SQLServer is very simple, but generating the login system is a bit harder I think. In the old days I would just make a recordset and the do something like If (rs.BOF or rs.EOF) then bla bla bla and the but the username or userID into a Session, but that seems to not be the way to do it in ASP.NET/Visual Basic?
"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".
The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.
I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.
So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?
I am trying to insert a row into a table of Microsoft SQL Server 2000.
There are various columns.
[SNO] [numeric](3, 0) NOT NULL , [DATT] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [DATTA] [char] (3000) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [CODECS] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
The [DATTA] column is causing a problem. Even if I am trying to put only 1700 character string into [DATTA], the java code throws the following exception:-
StaleConnecti A CONM7007I: Mapping the following SQLException, with ErrorCode 0 and SQLState 08S01, to a StaleConnectionException: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Connection reset
at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)
Why is it throwing an exception even though the sum-total of this row doesn't exceed 8000 characters?
I have system id information in table system_ids and productids and systemidinsformation has lot of data but I am looking two strings in tire data to pull into two separate columns. details below
Database versions :ms sql 2008/2012 tablename:system_id's column:system id information
sample data from system_id_information column

and after string </identifierValue><identifierType><label>Service tag
and snumber is always between the before and after string and number of characters of snumber varies and entire data for a row also varies
I am trying to write a query in sql query analyzer that will extract a date that appears after the first comma in the string. An example of the data is below:
Hello, I am tring to add a string my database. Info is added, but it is the name of the string, not the data contained within. What am I doing wrong? The text "Company" and "currentUserID" is showing up in my database, but I need the info contained within the string. All help is appreciated!

I have a sp which works fine from my local database. I move the procedure to a different database and modify it to access my data via linked server and I get the following:
provider "SQLNCLI" for linked server "Production" returned message "String data, length mismatch". Msg 7421, Level 16, State 2, Line 27 Cannot fetch the rowset from OLE DB provider "SQLNCLI" for linked server "Production". .
Now I've seen references to this error message for ODBC, but as I said above, the same SP works fine if it goes against local data views. I am working with rather long concatenated strings using nvarchar(max) as the data type.
I've tried cast() on just about everything to no avail.
I am trying to erase some erroneous bad data in my table. The description column has a lot of </div>oqwiroiweuru</a> weird data attached to it, i want to keep the data to the left of where the </div> erroneous data begins
update MyTable set Description = LEFT(Description(CHARINDEX('<',Description)-1)) where myid = 1
that totally works.
update MyTable set Description = LEFT(Description(CHARINDEX('<',Description)-1)) where myid >= 2
gives me a Invalid length parameter passed to the LEFT or SUBSTRING function. The statement has been terminated error.
I'm presented with a problem where I have a database table which must be migrated via a "custom tool", moving the data into a new table which has special character requirements that didn't exist in the source database. My data resides in an SQL Server 2008R2 instance.
I envision a one-time query which will loop through selected records and replace the offending characters with --, however I'm having trouble understanding how this works.
There are roughly 2500 records which meet the criteria of "contains bad characters", frequently containing multiple separate bad chars, and the table contains roughly 100000 rows.
Special Characters are defined as #%&*:<>?/{}|~ and ..
While the field is called "Filename" it isn't always so, it is a parent/child table where foldernames are also stored.
The examples I'm finding are all oriented around SELECT statements, to change the output of what I see returned, however I'd rather just fix the entire column using an UPDATE. Initial testing using REPLACE fails because I don't always have a single character as the bad thing in a string.
In a better solution, I found an example using a User Defined Function to modify the output of a select, but I cannot use that UDF in an UPDATE.
My alternative is to learn enough C# to modify the "migration tool" to do this in-transit, but I know even less about C# than I do of SQL.
I gather I want to use @@ROWCOUNT to loop through the rows but I really can't put it all together in a cohesive way.
I have a scenario where in I need to use a comma delimited string as input. And search the tables with each and every string in the comma delimited string.
We have some URLs within a bulk block of text some of which are very long. I need to identify rows where such urls exceed say 100 characters in length in amongst other text.So the rule would be return a record if within the string there is a string (without spaces) longer than 100 characters.
I have following query which return me SP/Views and Functions script using:
select DEFINITION FROM .SYS.SQL_MODULESNow, the result looks like Create proc create procedure create proc create view create function
I need its result as:
Alter Procedure Alter Procedure Alter Procedure Alter View Alter Function
I used following
select replace(replace(replace(DEFINITION,'CREATE PROCEDURE','Alter Procedure'), 'create proc','Alter Procedure'),'create view','Alter View') FROM .SYS.SQL_MODULESto but it is checking fixed space like create<space>proc, how can i check if there are two or more spaces in between create view or create proc or create function, it should replace as i want?
When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...
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?

A data reader is using a connection manager to connect to an ODBC System DSN . A query in the SqlCommand property is provided. Data is being truncated in the only string column . The data type in data reader output-->external columns shows as Unicode string [DT_WSTR] Length 7.
The truncated output in a text file is the first 3 characters from left to right . Changing the column order has no effect.
A linked server was created in SQL Server Management Studio to test the ODBC System DSN using the following:
Data returned using "OPENQUERY" does not truncate the string column indicating that the ODBC Driver returns data as expected with sql 2005, but not with the Data Reader.
I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A: (name phone house cost of house,zipcodecountystatecountry) -a view will later split this large varchar string based column b: is the source filename of the data load (varchar 256) ....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?
When using AquaData or JDBC (inet tds driver), when doing an insert using SqlServer 2005, I get error "String or binary data would be truncated" when the data is actually OK. There are no triggers, etc. that would confuse the situation. It works fine in SqlServer 2000.
Create and populate table: create table maxtable ( tablename varchar (18) not null, [...] )
Try to insert into test3: insert into test3 (name, tbname) select i.name, o.name from dbo.sysindexes i, sysobjects o, maxtable m where i.indid > 0 and i.indid < 255 and i.id = o.id and i.indid = 1 and o.name = lower(m.tablename)
And I get the error "String or binary data would be truncated." The values being selected for i.name and o.name have maximum length of 18. There are other rows in sysindexes and sysobjects with longer values, but they are not being selected.
The error does not occur with SQL Server Management Studio, and does not occur using SqlServer 2000.
Hi! Need help with this one: I have a column with a string composed by several data. After using REPLACE several times, I get something like the data below, which has (in most of cases) a value and a date.
378 9/05
388 9/05
4/05
1/06 606
1/06 646
76 5/05
100 1/05
118 8/05
129 8/05
9/05 342
05/3 123
1/07
4/06 164 The problem is that I need to get each value alone (to separate columns), in example: Value Date 378 09/2005 388 09/2005 0 04/2005 ... 606 01/2006
and so on... In addittion you can see that sometimes the Value come first or alone, and sometimes the Date come first or alone.
I will appreciate any good ideas, Thanks in advance, Aldo.
As you can see in Table 1, if a CustomerID has only one StaffID associated to it, the "Percentage" Column's value is 1. In the cases where there is more than one StaffID associated to a particular CustomerID, the percentage column get's split up among the StaffIDs, however the sum of this split can never exceed 1 (100%) per CustomerID.
I need to know how to find the cases where there is more than one StaffID associated to a CustomerID, group the CustomerIDs, and build a string made up with the StaffID and Percentages as shown in Table 2.
Any help would be greatly appreciated, as I've struggled with this one for a while and have hit a brick wall.
I'm trying to import a student id in one database (nvarchar(7)) to int in another database. No sure whether I need ato use cast or convert. Anyone have some examples?
<p> Hi everybody, I was hoping to get some advice something I can't quite get my head around. I have a SQL db which contains a table with ratings using the AJAX rating control. When someone rates an object, I need to select the current rating and then use those numbers to; - calculate the new average - add new score to total score - increment number of votes by one.
I thought this can be best achieved using the SELECT statement and then parsing the SELECT string. (is the string comma separated?) using each array, i'd need to convert this into integers and then do the calculation. and re-upload the data to the ratings table (using the UPDATE statement).
Is this the best way of proceeding? I have tried initially to write the code using three sql statements. But that would mean to many requests from the server, right? Below is the conde I have writting already.int myrating; myrating = Rating1.CurrentRating;string getscore = "SELECT " + "RatingScore" +"FROM Rating " + "WHERE ItemID= '" + _ItemID+ "'";string getcount = "SELECT " + "RatingCount" +"FROM Rating " + "WHERE ItemID = '" + _ItemID + "'";string getaverage = "SELECT " + "RatingAverage " +"FROM Rating " +"WHERE ItemID = '" + _ItemID + "'";
int _ratingscore;int _newscore; _ratingscore = int.Parse(getscore); _newscore = _ratingscore + myrating; //add new rating score to old scoreint _ratingcount; int _newcount;_ratingcount = int.Parse(getcount); _newcount = _ratingcount + 1; //increase count by 1int _ratingaverage; int _newaverage;_ratingaverage = int.Parse(getaverage); _newaverage = _newscore / _newcount; //calculate new average rating otherwise otherwise would i be best off to do the following?... string[] dbRatings = SQLstring.Split(','); ?? Any help would be appreciated. Many thanks in advance. Phil
I am writing a stored procedure that generates a computername for new workstations. Our naming standards, based on terminal ID's, are as follows: 'R' + X + Y + ZZZ, where 'R' is the letter 'R', X is a hex digit indication a locatoin, Y is a hex digit indicating business line, and ZZZ is a hexadecimal sequential number assigned within each location/busines line, for up to 4096. (This isn't a perfect naming standard, but is an improvement over the one that preceded it and is a requirement for our legacy applications). I can do everything fine, and calculate the sequential number using an int. Once I have the new number, I am trying to convert the integer to a varbinary, then convert that to a string, then use RIGHT to get the rightmost three characters of the hex string. set @SEQNUM = 4095 set @HEXSEQNUM = CONVERT(varbinary ,@SEQNUM) PRINT CONVERT(varbinary ,@SEQNUM) -- displays 0x00000FFE etc. PRINT 'HEXSEQNUM ' + @HEXSEQNUM -- displays 'HEXSEQNUM'
I have a web site that allows user to enter large strings into a database (comments, etc). What is the best way to do that? Right now I have them limited to 25 characters and the data type is varchar. Is there a better way?
I'm not a programmer by trade, so please be gentle with me! I am trying to add or insert data to the beginning of an existing string of data. The string is in one field in a table, with various options seperated by [ ]. An example of the current data is: [Eye Color:TEST][Hair Color:TEST] and I would like to add the data [# Persons:1] to the beginning of the string so it looks like this: [# Persons:1][Eye Color:TEST][Hair Color:TEST]
