SQL Server :: How To Iterate Through Rows Of A Temp Table
Mar 21, 2011
Suppose I have a temporary table (Shown below). The table is defined and populated in my stored procedure. After it is populated, I need to go through every row in the table. Here is what I need to do :
Check if Amount2 > Amount1 If Amount2 > Amount1 then set Amount1 = Amount2
It feels a little akward for me to use the temp table.
I have an html table in an aspx page (C#) that has columns like
1.CheckBox 2.Text 3.Text 4.TextBox
I want to iterate through the table one row at a time and process (run a stored procedure based on column2) based on whether the checkbox is checked or not. How will I be able to do that?
As I tested SQL temp table drops every time when sql connection from ASP.NET is closed/open. Is this only way using it, or it can be used depends on ASP.NET session as well? I'd need to access temp table from more separate selects on more different pages on the web site, if it is possible.
I have such sql query, in which there are 8 to 9 temp table generated and from each temp table, I am fetching data with use of read table.
I want to store temp table output into gridview, but after using sqlcommand,I am able to display first temp table output into gridview, but after executing query first temp table destroyed and second sql query which is using first temp table, is not getting reference. as first temp table is not available.
e.g. #temp1 -> I am able to display out put in grid view & destroyed
#temp2 -> which is using #temp1, but not getting reference of #temp1.
i would like to retrieve data from two table, how can i create a temp table and then insert data from two different table.and then use the temp table to join other table in stored procedure.if i want to select same data from two table, how can i select all distinct data from two table into temp table
I want to create a temp table to store data in a stored procedure and then then retrive it from the code. I need to save the data in the begining before it is deleted.And then after the inserts are done I want to update the tblcontactlist by referring to the temp table.
I'm trying to call a linked server, SS2000 that has NText field and instert that data into an nvarchar(120) field on SS2008.
If I execute the SPROC from SS2008 Management Studio, it works fine. If I try to call the SPROC from my ASP.NET 3.5 web application, I don't get any errors, but the data doesn't get updated.
I'm using the following SPROC: CREATE PROCEDURE [dbo].[usp_UpdateMilestoneDescription] @UID int AS BEGIN
I am creating a temp table and populating it's two columns manually and the rest of the table from the data returned by the stored procedure. When I added the first column called custno as @CustNumber, it allowed me to add it fine and the rest of the columns were filled by the stored procedure as expected. I then needed to add another column called RepeatCustomer the same way but it keeps saying:
Msg 207, Level 16, State 1 Invalid column name 'Repeatcustomer' So eventhough I have added Repeatcustomer column it's not seeing it. Any one has seen this error before or know what's wrong with this code. Note when I parse the query it's fine, it only fails upon the execution.
I have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.
I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this:
I want to select many rows from my SQL Server database and combine them in a certain manner. Currently, I've been using the following method to get these rows:
I am having a problem. I need to check to see if a row has been displayed once, and if so don't display it again. I have the following code:
[Code]....
This all works perfectly, but displays the body row repeatedly. So i need to add a counter or something to check this and make sure it is only displayed once..
I tried with DISTINCT in the sql but that didn't work, so i think it may be better doing it through iteration? Can this be done?
I've got a datatable in a dataset which contains 44 rows. I can iterate through the rows and add the data to a placeholder - it's all there. However, if I bind a control (say a gridview or dropdownlist) to the datatable, all I get is one record (from the "middle" of the table). I get the same result when I create a dataview of the table - one row.
I have one table named 'dbo.ac_Products' Within this table there is a column named 'ProductId' There is also another table named 'dbo.ac_CatalogNodes' Within this table there is a column named 'CatalogNodeId' and a column named 'CatalogNodeType'
I need to delete all the rows from 'dbo.ac_Products' and 'dbo.ac_CatalogNodes' where 'ProductId' = 'CatalogNodeId' and 'CatalogNodeType' = 1
I have table a and would like update table a whose values from table b, but not update all rows at table a. Only update record ID in table a match record ID in tableC.
Here is my query
update a set a.Desc = b.Desc, a.Value = b.Value from TableA a, TableB b where a.name = b.name and a.ID = b.ID and a.ID in ( select ID from TableC)
I only have 12 a.ID match TableC, but above query update whole TableA.
How to only update 12 record at TableA from TableB?
Actually what i am doing in my Data Access Layer dragging store procedure to TestDbml to display records and creating data context instance in BAL to retrieve records and my method in BAL is like this
public IEnumerable display() { using (TestDataContext db = new TestDataContext()) { var display = obj.USP_Actor_View_Speciality(p_UserName, 1); return display as IEnumerable; }
Now the problem is that how can i iterate or fetch over the records and display accordingly in my Presentation Layer so that i could return all the field parameteres Like ield1=val.field1,field2=val.field2.
I am doing this in my stored proc. Creating a temp table. Dumping the select results into the temp table and then select the info where the search string is based on the status name info.
because of the temp table, it is taking long to excecute. How can I get rid of the temp table and still seach based on the CurrentStatusName
Create proc [dbo].[usp_GetRequestsInfoOnSearchString] ( @SearchString varchar(100) ) as Create TABLE #Request( [RequestId] [int] NULL, [RequestDate] [datetime] NULL, [RequestText] [varchar](500) NULL, [CurrentStatusId] [int] NULL, [RiskLevelId] [int] NULL ) INSERT into #Request ([RequestId] , [RequestDate] , [RequestText] , [CurrentStatusId] , [RiskLevelId] ) SELECT [RequestId] ,[RequestDate] ,[RequestText] ,CurrentStatusName = dbo.udf_GetRequestStatusName(CurrentStatusId) ,[RiskLevelId] FROM [dbo].[Request] select [RequestId] as [Request Id] ,[RequestDate] as [Request Date] ,[RequestText] as [Request Text] ,[CurrentStatusName] as [Current Status Name] from #Request WHERE ([CurrentStatusName] like @SearchString OR len(@SearchString)= 0 OR @SearchString is null)
I can join with a regular SQL table fine but this won't work:
SELECT normalTbl.*, tmp.fld1 FROM normalTbl LEFT JOIN #Temp tmp ON tmp.joinID = normalTbl.joinID
All tmp.fld1 values are shown as NULL even though fld1 contains valid values and the joinID matches the normalTbl (when I call SELECT * from #Temp). If I do the same exact thing with a regular table, fld1 shows the correct value. What am I doing wrong?
