Need Help With Query String

Feb 4, 2008

I inherited a project at work in which I have to diagnose a bad query string that should be passing a value. Below are what I hope are relevant pieces of code. Your help ASAP will help insure job protection for yours truly. Thanks.

Dim strSQL as String = "SP2 "
'strSQL = strSQL &  Request.Cookies("ODM")("User_ID_NO") & ", "
strSQL = strSQL &  Request.Querystring("queue_id")
strSQL = strSQL &  ",'" & Request.Querystring("subtype")+ "'" ''xx no subtype is being passed here
Part of SP2:SELECT
'<A target="new" href="../document-ds.aspx?dcn=' + CAST(A.DCN AS VARCHAR(25)) + '">' + CAST(A.DCN AS VARCHAR(25)) +
'</A>' AS 'DCN', QUEUE_NAME AS 'Queue Name', DOC_SUBTYPEDESC as 'Department' , DOC_CLASSDESC as 'WorkGroup',
DOC_TYPEDESC as 'Doc Type' , WKF_SUBMIT as 'Received Date', QI.QUEUE_DATE as 'Queue Date',
dbo.MIN2PARTS(DATEDIFF(mi,A.WKF_SUBMIT, GETDATE())) as 'Doc Age',
CASE
WHEN (DBO.SLA_HOURSDIFF_DCN(A.WKF_SUBMIT, GETDATE(), A.DCN) - SLA_HOURS) > 0 THEN
'<font color = red> ' + CAST(DBO.SLA_HOURSDIFF_FORMAT( DBO.SLA_HOURSDIFF_DCN
(A.WKF_SUBMIT, GETDATE(),A.DCN)) AS VARCHAR(25)) + '</font>'
WHEN (DBO.SLA_HOURSDIFF_DCN(A.WKF_SUBMIT, GETDATE(), A.DCN) - SLA_HOURS) < = 0 THEN
'<font size = 2 color = green><b> 0 </b></font>'
WHEN (DBO.SLA_HOURSDIFF_DCN(A.WKF_SUBMIT, GETDATE(), A.DCN) - SLA_HOURS) IS NULL THEN 'No SLA Configured'
END AS 'Out of SLA', (DBO.SLA_HOURSDIFF(A.WKF_SUBMIT, GETDATE()) -SLA_HOURS) as 'SLA_HOURS'
FROM
T_WF_DOC_TYPES DT
INNER JOIN T_WF_AP_TRACKING A ON A.DOC_ID = DT.DOC_ID
INNER JOIN T_WF_QUEUE_INV QI ON QI.DCN = A.DCN
INNER JOIN T_WF_QUEUES Q ON Q.QUEUE_ID = QI.QUEUE_ID
WHERE Q.QUEUE_ID = @QUEUE_ID
AND DT.DOC_SUBTYPE = @DOC_SUBTYPE

My main task is to discover where the @DOC_SUBTYPE comes from and why it's not passing the value to the stored proc or beyond.
Let me know if you have any other questions since I'm unsure if I gave you the right info or not.

Procedure Or Query To Make A Comma-separated String From One Table And Update Another Table's Field With This String.

Feb 13, 2006

We have the following two tables :

Link  ( GroupID int , MemberID int )
Member ( MemberID int , MemberName varchar(50), GroupID varchar(255) )

The Link table contains the records showing which Member is in which Group. One particular Member can be in
multiple Groups and also a particular Group may have multiple Members.

The Member table contains the Member's ID, Member's Name, and a Group ID field (that will contains comma-separated
Groups ID, showing in which Groups the particular Member is in).

We have the Link table ready, and the Member table' with first two fields is also ready. What we have to do now is to
fill the GroupID field of the Member table, from the Link Table.

For instance,

Read all the GroupID field from the Link table against a MemberID, make a comma-separated string of the GroupID,
then update the GroupID field of the corresponding Member in the Member table.

Please help me with a sql query or procedures that will do this job. I am using SQL SERVER 2000.

SQL Query To String

Dec 10, 2007

Hi,
 I'm self learning asp.net and have a little experience in vb.net. What i'm trying to do is run an SQL query and write the results into variables. The SQL query's im running will only ever return 1 row (specifing primary key / uniqueID). This is becasue i dont want to output the results as a table, rather to other objects. (using VS Web Developer express 2008)
 Currently my code is:
------------------------------------------------------------------------------------------------------------------------------------------------------
Imports System
Imports System.Data.SqlClientPartial Class details
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Dim VariablesDim job_id As Integer
Dim myConnection As SqlConnection
Dim var_jobid As String = ""
Dim var_2 As String = ""
Dim var_3 As String = ""Dim SQL_read As New Object
 
'Write valus to Variables
job_id = Request.QueryString(job_id)SQL_read = "SELECT * FROM TABLE_NAME WHERE job_id = " & job_id
'Write Variables and Text to labelsLbl_title.Text = "Details for Job " & job_id
Lbl_jobid.Text = job_id
'Try to Establish link to SQL Server
'===================================
TrymyConnection = New SqlConnection("server= [my server here] ; database=ServerLog ; User Id = sa; Password= [my password here]")
myConnection.Open()
--------------------------------------------------------------------------------------------------------------------------------
I realise the quality of the code may be pretty abismal, due to pretty much guessing my way through. I dont know how to basically 'run' my sql query for starters, and then to output the results into variables. -IE- coloumn 1 (row1) of my results being put into var_1, column 2(row1) being put into var_2 etc etc.
 
Thanks in advance

Query A String

Nov 20, 2013

I have a query on a peson application that poduces a record. Within the application there is a question that allows the applicant to choose several answers: -

Applic_no Question_ID Question Answer
12345 40 Medical 2,5,12

There is a lookup table that tells me what each answer is: -

ID Desc
1 Stairlift
2 Wheelchair
3 Walk-in shower
5 Ramp
12 WC Downstairs

However, how do I query the lookup table if my answer is 2,5,12? I need to somehow split it or query the string array to pick out the values seperated by commas.

Query String Using Web Matrix

Jun 16, 2006

Hi folks,
I have two tables in one database.
One table has an automatic numbering primary key named ID and is named rfi.
The other table has a field named rfinumber and is named discussion.
Both ID and rfinumber have a datatype of number.
Upon using the querybuilder with Web Matrix, I issue a select command to get all records from the discussion table that have a rfinumber field equal to the ID field in the rfi table.
Problem is that I am getting the entire discussion table when I use the following query:
"SELECT [discussion].* FROM [discussion], [rfi] WHERE ([discussion].[rfinumber] = [rfi].[ID])"
For example
DISCUSSION TABLErfinumber1112
RFI TABLErfi12
Given the query, I should get a discussion table only listing the rfinumber = 1.
When I run the query from my database package it runs fine??
Any clues?
thanks,glenn

Hello,I would like to keep some values as session variables while the user is loged in, but i am missing some part of how to implement it.This is what I have:<script runat="server">

Protected Sub Login1_Authenticate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.AuthenticateEventArgs)

Dim conn As SqlConnection
Dim cmd As SqlCommand
Dim cmdString As String = "SELECT users.username, users.password, users.FirstName, users.LastName, users.CompanyId, Company.CompanyName, users.SecurityLvl FROM users LEFT OUTER JOIN Company ON users.CompanyId = Company.CompanyId WHERE (users.password = @Password) AND (users.username = @Username)"

Question About SQL Query String

May 3, 2008

I am sorry for my basic question I am sure.  I have this SQL Query that attaches to 3 tables and pulls data in:
Select OffNormalInfo.OffNormalID, OffNormalInfo.CompanyID, OffNormalInfo.SiteID, OffNormalInfo.CaskID, DATEPART(mm,EventDate)as Month, DATEPART(dd,EventDate)as Day, DATEPART(yyyy,EventDate)as Year, EventName, Damage, Action, UnitIDVCC, UnitIDTSC FROM OffNormalInfo, DamageInfo, CaskInfo WHERE OffNormalInfo.OffNormalID = DamageInfo.OffNormalID and CaskInfo.CaskID = OffNormalInfo.CaskID
Now, the main table that has the main document that everything else rides off of is the OffNormalInfo table.  The CaskInfo table will also always have data in it, but there could be an instance where the DamageInfo table doesn't have a corrisponding record with the same OffNormalID as the OffNormalInfo table.
What is happening right now with this string is that nothing is being returned at all for that OffNormalInfo record if there is nothing in the DamageInfo table.  There are also many times that the DamageInfo table has multiple records with the OffNormalID and so it returns the entire row multiple times with the same info from the OffNormalInfo table - this is how it is designed and is working correctly.
So - the question.  How do I change my SQL to get it to still return everything in the OffNormalInfo table and CaskInfo table even when there is not a corresponding record in the DamageInfo table?  In this event I would like it to show the two columns (Damage and Action) with empty strings in the GridView.
Any thoughts would be appreciated.
Thanks!
Tim

Query String Is Being Truncated

Aug 16, 2004

Hi,
I have hit a brick wall with this. My code is as below


public void fillCustomer()
{
string connectionString = "server='local'; trusted_connection= true; integrated security=sspi; database='Mrbob'";
System.Data.SqlClient.SqlConnection dbConnection = new System.Data.SqlClient.SqlConnection(connectionString);
string queryString = "SELECT * FROM [Customer] WHERE ([CustomerID] = @CustomerID)";
System.Data.SqlClient.SqlCommand dbCommand= new System.Data.SqlClient.SqlCommand();
dbCommand.CommandText = queryString;
dbCommand.Connection = dbConnection;
System.Data.IDataParameter param_CustomerID = new System.Data.SqlClient.SqlParameter();
param_CustomerID.ParameterName ="@CustomerID";
param_CustomerID.Value = customerID;dbCommand.Parameters.Add("@CustomerID", SqlDbType.Int);
dbCommand.Connection.Open();
System.Data.IDataReader dataReader = dbCommand.ExecuteReader();
dbCommand.Connection.Close();
while(dataReader.Read())
{
customerID = dataReader.GetInt32(0);
date = dataReader.GetDateTime(1);
eposCode = dataReader.GetInt32(2);
}
dataReader.Close();

}

The error I am getting is

Prepared statement '(@CustomerID int)SELECT * FROM [Customer] WHERE ([CustomerID] = ' expects parameter @CustomerID, which was not supplied.

As you can see from my queryString the @CustomerID parameter is passed in. It seems as if the string is being truncated at 64 characters long. If I remove the paramter to pass the relevant infomration and pass in a customerID I know exists it works.

I am really stumped on this and would really appreciate any pointers

SQL Query Using String Condition

Aug 1, 2004

My table is as follows and I have a string ‘U2’,’U4’

CustomerID UserID OtherUsers
C1U1#U3~#U5~
C2U2
C3U3
C4U4#U1~#U2~
C5U5
C6U1#U2~#U5~
C7U2
C8U3#U1~#U4~

Now I should issue a sql which should extract the CustomerID where UserID in (‘U2’,’U4’) or (U2 or U4) in OtherUsers.
i.e I should get the CustomerIDs C2,C4,C6,C8

I have trouble in coming out with the sql. Does anyone have idea how to achieve this?

Concatenate String In Query

Apr 22, 2008

Hi,

As I build a record set in an SP I need to add in a string containing a list derived from a second query. I need the results of the sub query to be presented as a single string in the first query, separated by a single space.

I have no idea how to do this in t-sql, and am doing it on the web server at the moment, but becase the dataset is quite large, I'm getting 20 - 40 second processing times which is far too long.

I have found reference to the xp_sprintf function but this is not supported by my host, so not a solution.

I'm no expert in t-sql, so I imagine there's a way somewhere, and would be grateful for any advice available.

regards,

NEIL

Concatenated String For Each Row In A Query...

Mar 31, 2008

So I've run into another problem. I've figured out how to concatenate multiple rows into a single string my only problem is using that on another query with multiple rows...Basically what I'm trying to do is pull up information for each class a student has in his/her profile and while at it pull up any prerequisite classes that are associated with a certain class. So the final query would look something like this...

StudClassID Completed Class ID Name Description Credits Prereq... rest are insignificant...
0 0 CSC200 Cool prog... blah.... 3 CSC160, CSC180

I get the concept of the coalesce and cast just i'm not understanding how to get it to work with each return on the main select...anyways below are the tables and my current query call...

Query String In A Textbox

Apr 10, 2007

As I'm searching for solutions to my problem (see my most recent post before this one if you're interested), I keep coming upon "command-based expressions." I keep seeing examples such as:



= "select a,b from table1 where c=0"



I can't put that in a textbox can I? I tried it and it just spits out the string on report execution, it doesn't actually execute the command.



So what's up? Should that be able to be put right in a textbox? That would solve a world of problems for me if it could be.



Thanks for any info, as always.

SQL Datasource Passed To Query String?

Aug 8, 2006

I have been attempting to build a search engine that searches a database full of invoices. The user will enter in a invoice number and then the results will be returned if the exact invoice exists and if the record belongs to the user.
My first attempt has involved the use of a SQL Datasource to pass a stored procedure based on what is in the search textbox and the information in the cookie about the user.  I was hoping that on the btnsearch.click event that I could somehow return the stored procedure in the SQL DataSource. My next step was to make the result (if exists) part of the query string like this:
Response.Redirect("~/Invoice.aspx?Invoice=?"+ SQLRETURNEDVALUE)
 
I'm looking for any help to a possible way to use my idea or any other ideas to get a invoice number and place it into a query string so that the result can be fetched on the next page. Thanks

String Manipulation With Web Form Query

Feb 24, 2006

I'm trying to look up customer records by e-mail domain by using a text box on a Web form. So if I want to look for all my customers that have an aol e-mail domain, I would type aol.com in the text box and the sub routine would know to count 7 characters from the right and through those characters into maybe a parameter query. I'm having problems passing this in. I can count the characters properly by using:
dim strText = MyTextBox.Textdim intLength = strText.Length
but having problems starting here......
MyCommand.SelectCommand.Parameters("@email").Value = MyTextBox.Text
..............
but how would I ultimately feed this into my sql satement? Select * from Customers Where email = right(@email,intLength)
Help appreciated.
Frank

Query To Update Partial String

Mar 21, 2000

Sorry, I realize that this is probably a pretty simple question for you, but I am in a quick time bind and would really appreciate it if someone could help me with this update that I'm trying to run.

Let's say you have a table (call it testtable) that contains the column "text".

Now in column text you want to replace all instantiations of the phrase "in the US" with "to the United States", how would you structure your update query to perform this change (Please note that this phrase could be embedded in the middle of a larger sentence like 'Send a package in the US'. You'd want to change this instance to 'Send a package to the United States')

Thanks in advance, I really appreciate it guys.
