SQL Server :: SQL - Looping Through Fields In Each Record.?
Jan 14, 2011
to loop through each field in a record to test for a value and then set a flag at the end of each record if an instance of this value occurs in any fields?I have a table where some fields values are have a *c* at the beginning of the text eg "*c* value" . What I would like to do is run a select query off the table and at the end of each record have a field called "Change Flag" and a value of "Changed" or "No Change" depending if a *c* has been encountered.
There are a number of tables to run this against all with differening numbers of fields/

Table1 - T1Col1(varchar) T1Col2(int) T1Col3(varchar)
Table2- T2Col1(varchar), T2Col2(varchar), T2Col3(int)
Table3- T3col1(varchar),T3col2(varchar)
For every record in Table1 I need to loop through top 10 records in Table2 - check this condition if( T1Col2 element & T2Col3 element)/T2Col3 element = 1 and insert T1Col1,T2col1 in to Table3

I try to access to the fields of each single record in the table without writing the specific name of the field,
For example , checking each property of the record whether it's null or not,
something like that:
var myUser = from u in dataContext.Users
select u;
foreach (User item in myUser)
{
// Here I wand to access to the fields by their ordinal number.
}

consider the follwing table, this table actually shows which id was given a new id
i.e 11 was assigned 13
again 13 was assigned 15
15 was reassigned 17....and so on actually 11,13,15,17,19 represent the same user (hope u understood)
customerId rejoiningId
11 13
13 15
15 17
20 21
17 19
48 50
21 25
i need to loop through all the rows and find the relation that which all ids are interlinked
say the user enters the rejoining id -13,hence the result should come out to be as 11,13,15,17,19
if user enters 21result should be 20,21,25
it takes a bit of looping statements in query that i couldnt figure out

I'm using cursor to select a list of records in sql server 2005
There are 80+ columns in the result, the cursor parameters named as @pn1,@pn2,@pn3... @pn12. @pid1,@pid2,@pid3.... @pid12
[Code]....
The above code rotates the parameter ('@pn' + loop id) to get the cursor parameter value.

I've got a gridview with three fields, the last of which is a template field with an imagebutton in.
The first field is a Date, and the second is a time field (it is however just varchar field as it may differ and will not be programmatically used).
I want the following to happen if I click on the imagebutton (reserve):
Four other fields must be inserted into the record.
Is the best way to launch a detailsview where the row.imagebutton@=ID and just edit the fields like that or should I pass the two fields (and RecordID) along with the query string to a new page where the passed information can be in invisble textbowes and just have the user enter (UPDATE) the four outstanding fields? I feel like doing it this way?
can read on 1. setting up the onrowcommand code for the templatefield 2.
This should be simple as it is only one table with records that has to be partially inserted by an admin person (2 Fields) and then completed by a web user (4 fields).

I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.

I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?

I am working on Crystal Reports 8.5 and SQL Server 2000 as backend. I have a stored procedure which has been added to the Crystal Report. So that fields are visible in the Fields object section from where i can drag and drop the fields on the report and display it. But now as they want more fields i have written two select statements for displaying required fields. But these newly added fields are not visible in the Fields object section in the Crystal Reports. I have done verify database, removed and again attached the SP but the problem is not solved.

I got an excel spreadsheet (will have tons eventually) that have "Start Date" and "End Date" columns, with a format of "dd/mm/yyyy".For time being, I just want to import these to a temporary table in my database, and use the SQL Server Import/Export wizards.
Now this wizard import the the above fields as nvarchar, instead of date or datetime (not sure which would be better?).I tried to convert the columns to datetime after importing, but this is not allowed (Saving changes is not permitted. The changes you made require that the following tables to be dropped and re-created, ......).
So I deleted the temporary table, and ran the wizard again, this time trying to edit the mappings and specify the two fields to be date times, but this also fails.I also fiddled around with convert and cast, but always end up getting "Conversion failed when converting date and/or time from character string." errors.
I looked myself skew, and are pretty sure all the fields in the excel sheet do have values, and are in the "dd/mm/yyyy" format.(I've been absent from SQL for a long long time!)

I have taken over development of a asp.net 3.5, c#, MSSQL website, which I did not create.
There is a form on the website which adds all kinds of information into my SQL database. I have added two fields to the database, two corresponding extra form questions and added to the c# code behind so that these new fields are treated in exactly the same way as the existing ones.
I am therefore completely stumped as to why those two fields aren't populated in the database when I submit the form.
No page errors or anything, it's just the fields remain empty when the other pre-existing ones are populated just fine.
Is there something obvious I'm missing - for example is there a setting in the database I'm not enabling to allow the two new fields to be written to by my c# file?
I was not a programmer before this, I'm just picking it all up as I go along.

I was wondering if people out there test the length of their text values before inserting them into an SQL INSERT or UPDATE command? I got lazy and stopped doing it lately but I do restrict the length of some of my character fields so that I have a NCHAR(50) field but don't test the length of the string when inserting or updating and just rely on the server to fire back any problems.Am I being 'efficient' or 'lazy' or even 'dangerous'?I appreciate the opinion of you as just about anyone has more experience with SQL Server than I do.
