lets say i have a stored procedure (for insert command) which i am calling in my code to execute. The user provided data is being stored in a array. My class takes the stored procedure name and also takes parameters name and types. Is there any way to loop through the parameters, (various columns in the table which is of diffrent data type ie varchar, int, etc). How to implement it?
View 1 RepliesI am setting up a database and I would like to insert fields using sqlparameters into the database. What I need to know is the relation between sqlparameter size and db field 'length' field.IE: In the database does the 'length' field indicate bits?

Hi there!
I was trying to dynamically load a custom WebControl and display it into my WebFrom.
WebControl is loaded by:
System.Reflection.Assembly assembly = System.Reflection.Assembly.Load("myAssemblyName");
Control module = (Control)Activator.CreateInstance( assembly.GetType("myClassName") );
ModulePlaceHolder.Controls.Add(module);
This is working fine. Assembly is loaded and WebControl is created.
But as my Custom WebControl tries to access SQL Server database, i get a "Must declare the variable '@id'" while executing an ExecuteScalar() from a SqlCommand.
Code in my WebControl was perferctly functioning before converting it from a UserControl (.ascx) to Custom WebControl. Parameter '@id' is correctly declared in my query. If i don't use SqlParameters, everithing works fine...
Any ideas??
Thank you so much!!!

Im having a issue. Im not sure how I am going to carry out but I have two tables in SQL server 2005
TABLES
Category SubCategory (PK)CategoryName (PK) SubCategoryNameCategoryID SubCategoryIDDate Date (Just shows the date inserted) (FK)CategoryID
On the front page, I need to have it querys out the CategoryName from Categorys but also querys out all....Well not all but atleast 5 subcategorys that relate to that categoryName. Once its down it moves to the next category and does the same and so on. Does anyone know the trick ?
In my site, when a user registers, I need to create rows in additional tables besides aspnet_Users. So, I need to be able to pass the generated userId guid to subsequent SqlCommands. I'm having a terrible time with this. What's the correct way to set up a SqlParameter so that it will accept a guid? I keep getting this error: "Conversion failed when converting from a character string to uniqueidentifier."
I've tried creating the parameter both with and without a SqlDbType.
cmd.Parameters.AddWithValue(paramName, guid);
and
SqlParameter p = new SqlParameter(paramName);p.SqlDbType = SqlDbType.Guid;cmd.Parameters.Add(p);
and I get the same error either way.
Driving me nuts! Any help appreciated.
I want to loop through a recordset and do inserts into another table based on each record.
The way I have been doing it is copy my key data into a temp table,
Loop through temp finding the max ID
Doing what I need to do, deleting the max, then finding the new max and looping until no records exist.
I know there has to be a better way. The table I am working with is millions of records.
Thanks in advance,

I need to loop through a set of tables and move the data through a data pump from one server to another. This set of tables is dynamic so I have greated a global recordset and the looping is working fine.
During the looping process I need to change the transformations for each table so the source, destination, and transformation of the datapump are correct for the next table in the loop. I am using a VBS to handle this right now but cannot get the transformation to change. I essentially want to auto-remap using a vbs script. Is this possible?
Thanks for any help.
Hello clever people
I have a table that holds duplicates that I want to change into a table that has no duplicates. The current table is this
name
compound_id integer
name varchar(150)
name_type integer
This table stores chemical names. There is no primary key in the table so there are multiple compound_id's. I think the original idea was to have four name-types
1 = chemical name
2 = a description of the chemical
3 = a synonym of the chemical
4 = a formula of the chemical
I have created a new table called compound_name with this structure
id int primary key (auto identity)
compound_id int used as a foreign key
compound_name varchar(150)
compound_desc varchar(250)
compound_synonym varchar(150)
compound_formula varchar(50)
compound_trade_nme varchar(50)
I have also started to populate the new table by running this code
insert into compound_name(compound_id,compound_name)
SELECT DISTINCT compound_id, name
FROM dbo.name
WHERE (name_type = 1)
Now I need to somehow loop through the name table getting distinct compound_id's, and perform a case when name_type = 2 (which is synonym name_type) Then inside the loop update compound_name.compound_synonym for each compound_id which matches name_type 2
Then case 3 do the same for name_type 3 which is the name_type for descripton
Then case 4 do the same for name_type 4 which is the formula
Any help would be appreciated
Hi there, I am new to SQL and am having trouble looping a script. I have the following script that needs to be refreshed a large number of times, or needs to be looped indefinitely until stopped:

Hi All,
I would like to know the best way to approach the following requirement:
I have an ASP.net 2 web site which gets its data from SQL 2005.
I am trying to run a series of 'rules' which are SQL where statements stored in a table, against rows stored in another table. I open the 'Rules' table looping through all records. I copy each rule to a string and put it on the end of the SQL statement so that the rule will only be appended if it passes the rule... this may be a little confusing.
The rules process will fire when the details have been submitted to the database.
Table containg rules would contain something like:
ID, RuleSQL
1, (ClientAge >18)
2, (ClientIncome>10000)
3 Etc...
This a very simplified version of the table but gives the general idea.
I currently use ASP.NET 2 and sqlconnections/datareaders to do this. I would like to know if there is a way of doing the same thing server side using Transact SQL because that would (I believe) speed up the time taken to perform all the tests as i wouldn't need to rely on ASP to open all recordsets and append the data.
If the ASP route would be the standard way of doing it and is not likely to have a detremental effect on performance then i am fine to stick with it because i know it works.
any comments or suggestions would be welcomed.
Thanks,
Ian

I'm pretty new to T-SQL and have an *easy* problem, for you experts, that I can't get seem to get solved. I'd like to loop through a list of items in TABLE "Items". I then want to use that list to loop through and SUM SALES and QTY for each item from a TABLE called "Shipments". As I loop through each item, I want to UPDATE the "Items" table with the Summary data. So, logically I'd do something like this:
SELECT item_no
FROM Items
BEGIN
SELECT SUM(sales) AS Total_Sales, SUM(qty) AS Total_Qty
WHERE item_no=@item_no
UPDATE Items
SET Sales=@Total_Sales,
Qty=@Total_Qty
WHERE item_no=@item_no
END
I've tried somewhat successfully to use cursors to create my loop query, but I cannot seem to get the SELECT and UPDATE correct in the loop itself. Can anyone steer me in the right direction (or better yet, provide a solution)?
Thanks for the help,
Chris
What I have to do is loop through a table with about 900 records, do computations on each record and update a database, can someone help me out.
here is the code that I am using right now on another site with coldfusion but i want to convert it all to a stored proc for speed reasons.
<!--- Query the Stores Table --->
<cfquery name="Zip2" datasource="#application.data#" username="#application.username#" password="#application.password#">

<cfset Lg1 = #zip1.long#>
<cfset Lat2 = #zip2.lat#>
<cfset Lg2 = #zip2.long#>
<!--- Do the actual distance calculation between the user's zipcode each store's zipcode --->
<cfset DistLat = 69.1 * (Lat2-Lat1)>
<cfset DistLong = 69.1 * (Lg2-Lg1) * #cos(Lat1 / 57.3)#>

I am not sure if what I wish to do is possible, but I shall ask anyway;
My project examines a database log of all the pages of an online teaching tool. Once the user has completed all the pages they are to be issued a certificate. Users may complete the teaching tool in any order, and the pages are always stored whenever they are acccessed, regardless of certification.
I have created a number of views that extract the data into a list of all the possible completion dates; i.e. where all the pages have been completed within any 12 month period. I need to write a query/view that uses the view to extract the first possible user completion date followed by every completion 12 months after that, then after that etc. to present day.
Can I do this?
Am I making sense ?
A no is acceptable in this case; I know I can do this with multiple queries from withing an application. I'd just rather not.
hello,
i have a select query that returns multiple rows (within a cursor). How do i loop through the rows to process it (in a stored proc)? I donot want to use nested cursors. a code sample is requested.
thanks!
Hi All,
Very Ad-hoc requirement I am having.
I've got one table with two columns.
Column Name Data Type
1) Id Integer Identity
2) RemDate DateTime
I've to write one SP/JOB in that there will be an integer input parameter @numofday.
Say value of @numofday is 5 then.... in SP/Job I need to insert 31 - 5 = 26 records to above-mentioned table where date starting from 1st of current month.
This logic can be achieve through looping but if anyone can suggest some better way to achieve this functionality without use of looping.
Thanks in advance,
Jai

I want to apply the same query for 250 tables (see below).
It would be very painful to code 250 individual queries.
Is there a way to loop through all 250 tables using "sysobjects WHERE type = 'U'", and applying the below code for each table (users table would remain constant)?
select co.*
from company table_type
where not exists(select * from users u
where (u.users_id = type.rn_create_user) or (u.users_id = type.rn_edit_user)

Hi,
Hopefully someone can assist me with what appears to be a simple issue - and hopefully I am just looking in the wrong location - because I am almost going nuts trying to work this out!!
I am wanting to pickup a file from a given folder, do some transformations on the data within the file, and then dump each row within the original file as a seperate txt file into a new folder.
I have managed to get it working - well all except having each row as a seperate txt file. Currently all the rows are outputed into the same txt file. argh
As it stands I have a For Each Loop Container, within this i have a Data Flow Container; which in itself, just has the source, some derived columns, and then an output.
How can I get this to pull each row from the source and put it as a seperate txt file. If someone can just nudge me in the right direction it would be much appreciated.
Thanks in advance

Can anyone give me a hand on how to loop this query until there are no results left, this is going to be part of a stored procedure by the way.

Hello - I am somewhat new to stored procedures, so please be patient. I need to know how to go about wring a stored proc to loop through all of the tables in a db and delete the records in them.
I'm assuming a stored procedure is the best way to do this. If there is a better way, please let me know
I think I'm on the right track with this below
/* Create in each database that it is used in */
CREATE PROC usp_DBCCCheckTable
AS
/* Declare Variables */
DECLARE @v_table sysname,
@v_SQL NVARCHAR(2000)
/* Declare the Table Cursor (Identity) */
DECLARE c_Tables CURSOR
FAST_FORWARD FOR
SELECT name
FROM sysobjects obj (NOLOCK)

HI:
I am trying to loop through files in a directory. The tricky part here is that the last part of the filename has seconds, and I never know what that is. I need to use some sort of wildcard I think here. Basically I have a directory with these files:
Export20080112_01_00_08.csv
Export20080113_01_00_06.csv
Export20080114_01_00_03.csv
Once you have got the YYYYMMDD part you have a unique file, so the rest I don't care about. If I could just open the files the way you use a wildcard when you do Windows file searches I could store these in a table:
Export20080112*.csv
Export20080213*.csv
Export20080114*.csv
then use the For Each Container in SSIS for ADO and loop through the filenames. The other option is to use the For Each File but that has to loop through all the files.
Is there a good way to do this using a wildcard?
Thanks,
Kayda
