Question Regarding DataSet File (xsd) Like The Ones Used On 3-teir Design Tutorial
Apr 6, 2007
Hi everyone,
I have a question. I am using a DataSet file as my data layer in my app. I'm trying to create a event TableAdaptor where one of the queries has two paramaters (@start & @end). Those two variables are used to search for items that have start dates that fall in between the two.
Every time I try to use this, the smart tab always brings up three paramaters (DataTable, start as date, end as date). How the hell does that DataTable get thrown in there. I executed the query in the builder section and it only asks for the two variables.
When I click on the DataSet Query Desginer there is an Error Source:.NetSqlClient Data Provider. why this error comes and I have executed the SQL query in SSMS succesfully and the result comes. However this is causing the report from the report manager to fail.
When I insert the fields using parameters, the params look like this: paramValues(10) = New SqlParameter("@RegHrs", SqlDbType.Decimal) paramValues(11) = New SqlParameter("@OTHrs", SqlDbType.Decimal) paramValues(12) = New SqlParameter("@TotHrs", SqlDbType.Decimal)
The fields in the SQL table are defined as: RegHrs - decimal (9,2) OTHrs - decimal (9,2) TotHrs - decimal (9,2)
Before I insert the row (from w/in the VB code), I stop the code and verify that the values being placed into the params are: 5.85 0 5.85
After the SQL insertion, the values w/in the SQL Table contain: 6 0 6
with the help of the following code am able to read the text file now i need to insert values to the datatable in dataset can anybody help me on this regard
how shall i spilt them and add each value to two fields of the datatable
for example i have the fields in text file as Username1:Password1 Username2:Password2 etc i need to add the username seperatelt to a field called username in table and password in password field of the datatable an example with code would be better and helpful
I have some questions about creating SQL Server CE databases. Based on my experiments and what I've read on these forums, it looks like there are a couple ways to create a database schema. I can edit the database schema via the Server Explorer in Visual Studio, or use an external program like SQL Server Management Studio and somehow convert those files to .sdf files.
I find Visual Studio's built in tools to be cumbersome to use and limited in functionality, and using SSMS seems like a roundabout way of approaching the problem. I understand Microsoft will be releasing better tools with Orcas, but in the meantime, I'm wondering if there are alternative ways to generate database schemas.
For instance, I find Visual Studio's DataSet designer fairly easy to use. The DataSet designer generates schema definitions (.xsd files), and an instantiated DataSet can both read and write schema definitions via Read/WriteXMLSchema. Furthermore, DataAdapter's Fill and FillSchema methods can be used to push a schema from a database to a DataSet. So, can I somehow go the other direction and push a schema from a DataSet to a database? It seems like all the tools are there...
For example, if I create the DataSet schema, could I use a small app to create a new .sdf file, instantiate a DataSet, write the schema from the DataSet to the database, and then save the .sdf file? Or given the generated .xsd file, is there any way to create a SQL database from that?
I am trying to use the results of a query to build an XML file (this will eventually be data from a number of RDBMS's and will undergo transformations and unions prior to being saved as a package variable).
I have saved the results of my query to a result set variable (ADOResultSet) using the Recordset Destination.
I then try to use a script task to read the variable and create an XML file. I get a runtime error Unable to cast COM object of type 'System.__ComObject' to class type 'System.Data.DataSet'.
I am trying to upload a file in ASP.net 2.0 to a SQL database using the FileUpload control. I am doing this by way of a typed dataset.Here is my code.Dim rta As New ResponseTableAdapterDim rdt As ResponseDataTable = rta.GetResponseByID(1)Dim rr As ResponseRow = rdt(0)Dim fs As New FileStream(fu.PostedFile.FileName, FileMode.Open, FileAccess.Read)Dim br As New BinaryReader(fs)Dim image() As Byte = br.ReadBytes(fs.Length)br.Close()fs.Close()rr.UploadFile = imagerr.NameFile = fs.Namerta.Update(rdt)The code runs without an error but afterwards I find that nothing has been stored in the UploadFile cell in the database but the file name has been stored in the NameFile cell in the database. Any ideas?Your help is much appreciated. James
partition with single file group or multiple file group which one best.
we have some report running from partition table, few reports don't have any partition Key and after creating 400 partition with 400 file group it is slow.what is best practices to crate 400 file group or single file group.
Is there a redgate tool or any third party tool that would convert a .bak file to its appropriate .mdf and .ldf file? or create an .mdf and .ldf file from the .bak file?
I have a well-structured but also very large binary data-set that is generated by a C++ application every five minutes. The data needs to be accessed by SQL applications. Since data is generated every five minutes, performance is key, both for write and read. The data set is about 500MB.If data is written to the file system, the write performance doesn't involve SQL server. For reading it, I have a CLR to read the portions of the data that I need based on offset and length. That works and is very fast. The problem is that data is stored in the file system, so it is not self-contained within the database.
A second option that I haven't explored yet, is to write the data into a table as VARBINARY(MAX). I would read the data using SUBSTRING with appropriate offset and length. Performance of SQL write/read of binary data of this size, and whether there is a third option I haven't thought off. I'm using SQL Server 2014.
In my enviornment i have one database with 6 ndf files and 5 ldf files and one mdf file.Actuvally what i am looking is to merge 6 ndf files into one ndf file and 5 ldf files into one ldf file.is it possible to do like this? , i tried using MOVE and TO option while backup is restorating but getting below error messages.
ERROR: Msg 3176, Level 16, State 1, Line 4 File 'J:NDFabc.ndf' is claimed by 'Finance_data2'(4) and 'Finance_data1'(3). The WITH MOVE clause can be used to relocate one or more files.
I have a SQL script folder on my HDD. The folder contains SQL Scripts and subfolders with Constraints and Extended properties. I need a BAT file that builds a database on my SQL Server instance.
I need to create a text file using information from SQL tables/views in the following format...Can anyone recommend a direction or procedure to look into, i.e, sql script, custom dts, etc. The items in parentheses identify specific portions of the text file.
I am preparing to design an application that will archive files created by another application. In my SQL database I want to store details about the file and then the file its self. Each file is about 500kb in size and there will be about 20,000 files generated per year.
My preference is to store these files in a blob field. It makes storage, linking to file meta data, backup etc easy for me. I have already solved the technical issues surrounding pulling the file in and out of a blob field.
By my calculations I will need a server with 10GB of disk space for each year of files archived which doesn't seem outlandish for table size.
I do not want to design my application however to find out a year from now that I should have been storing these files in a traditional file system because of (... whatever ...) and just linking them by path in the sql database.
I'm curious what users of this forum believe to be the best practices surrounding this type of database?
I currently have a DB that is growing at a rate of 10gb per month. It is set to 1mb unrestricted growth and the log file is set to 400mb restricted growth. I take regular transaction log backups so the log file is well under under without any issue. This DB's recovery model is set to FULL as it has to be mirrored to a backup site. Any recommendations on how to control the growth. - Is it advisable to take create a new DB with data older than 2 years and transfer that file to an external drive and if i do this, can i "attach" it back to the main server if and when required ?
I have an SSIS script task using c#. i need to refere an .xsd dataset in the c# code. i tried to set property below.Build action to Content or Compile Copy to output directory Copy always But still i m unable to use the dataset in my code.
We have database when trying to make read only throwing below error: with stack dump
Location: recovery.cpp:4517 Expression: m_recoveryUnit->IsIntendedUpdateable () SPID: 51 Process ID: 6448 Msg 926, Level 14, State 1, Line 1 Database 'XXXX' cannot be opened. It has been marked SUSPECT by recovery.
See the SQL Server errorlog for more information. Msg 5069, Level 16, State 1, Line 1 ALTER DATABASE statement failed. Msg 3624, Level 20, State 1, Line 1
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 3313, Level 21, State 2, Line 1
During redoing of a logged operation in database 'XXXX', an error occurred at log record ID (0:0:0). Typically, the specific failure is previously logged as an error in the Windows Event Log service. Restore the database from a full backup, or repair the database.
Msg 3414, Level 21, State 1, Line 1
An error occurred during recovery, preventing the database 'XXXX' (database ID 7) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support.
Investigation DONE:
- DBcc checkdb shown Clean - database is online and able to access -Detached database and attached with rebuild log, still could not bring database read_only
I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.
I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1: Small table without CLOB, 10 rows. Table 2: Large table with CLOB, 10,000,000 rows
select CLOB from table2 where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.

I found out the data I need for my SQL Report is already defined in a dynamic dataset on another web service. Is there a way to use web services to call another web service to get the dataset I need to generate a report? Examples would help if you have any, thanks for looking
I have a database around 500 GB. right now the database have only one data file and one log, it has only one filegroup also.all the indexes and table are placed in Primary Filegroup . we are going to separate them. the planing is to move all the indexes to Secondary filegroup and all the table will be in Primary filegroup.But there will be a problem while implementing it because there are around 600 tables and each table have at least 2 non-clustered index , so is there any way to move all the index to Secondary Filegroup.
When I am working on an Integrations Services project and I open a Reporting Services file, it displays it in the Code view. Is there a way to display it in the Design view? Or do I have to close the project and open up a Reporting Services project?
I was putting a database together (its a C# application MSSQL) the application will handle a few hundred customers records and save maybe a couple of thousand word docs/images/other doc files wondered if the way to go was blob or filestream, I see the medium and larger databases seem to go for filestream but just wondered as not much mentioned about smaller dbs.I do not think security/disk space/super fast access will be a big issue.
Hi, I have a stored procedure attached below. It returns 2 rows in the SQL Management studio when I execute MyStorProc 0,28. But in my program which uses ADOHelper, it returns a dataset with tables.count=0. if I comment out the line --If @Status = 0 then it returns the rows. Obviously it does not stop in if @Status=0 even if I pass @status=0. What am I doing wrong? Any help is appreciated.
ALTER PROCEDURE [dbo].[MyStorProc]
(
@Status smallint,
@RowCount int = NULL,
@FacilityId numeric(10,0) = NULL,
@QueueID numeric (10,0)= NULL,
@VendorId numeric(10, 0) = NULL
)
AS
SET NOCOUNT ON
SET CONCAT_NULL_YIELDS_NULL OFF
If @Status = 0
BEGIN
SELECT ...... END If @Status = 1 BEGIN SELECT...... END
HI there... i'm really new to this, and i want to know if there is a tutorial of how to connect to sql database, display the data online, and run some queries....
