How To Modify This Code So That It Also Tests For NULL
Aug 2, 2004
Hi,
I'm trying to extend the usage of the code below. This method returns a variable of type SQLParameter and what I want is to accomodate even a check for a null in the parameter. This is a code which I got from one of my co-workers who isn't anymore working here. Any help would be appreciated. I do not want to throw an exception here when a field's type doesn't fall into one of the categories below. The method where this methos is called is the first part of my below code. Any help would be appreciated.
Pls check my code for the stored procedure which i created for the companydetails including companyid P.K. Not Null int(4),companyname Not Null varchar (20),address varchar(30) where companyid is the primary key and it should be autogenerate.I also want that it should check if the name exits or not.It should also check that the field is entered and not kept null.If it's null then should return the error message.I want to write the queries select,insert,update and delete in the single stored procedure.How can i differ all the query individually in a stored procedure.The select and insert query are done on the button click event whereas the update,delete queries are performed in the gridview link event. Pls help me and modify my code accordingly with ur suggestions who know the stored procedure very well.First read what i want then give reply.waiting for the reply and with corrections.The coding is perfomed in sql server 2005 and asp.net with C# 2005, 1 ALTER PROCEDURE CompanyStoredProcedure2 @uspcompanyid int,3 @uspcompanyname varchar(20),4 @uspaddress1 varchar(30), 5 @frmErrorMessage as varchar(256) OUTPUT,6 @RETURNVALUE as int OUTPUT,7 @RETURNID as int OUTPUT8 AS9 declare 10 @companyid int,11 @companyname varchar(20),12 @address1 varchar(30) 13 14 BEGIN15 16 begin17 Select @RETURNVALUE = -918 RETURN -919 end20 21 begin22 Select @frmErrorMessage = 'The Operation Mode Has Not Been Specified' 23 return -924 end25 26 27 28 begin 29 --validation... 30 if (@uspcompanyname is Null or @uspcompanyname = '')31 begin32 Select @RETURNVALUE = -933 select @frmErrorMessage = 'Company Name is empty' 34 return -935 end 36 37 if exists (select companyid from companymaster 38 where upper(companyname) = upper(cast(@uspcompanyname as varchar(20))))39 begin40 select @companyid = companyid from companymaster 41 where upper(companyname)=upper(cast(@uspcompanyname as varchar(20) ) )42 end43 else 44 45 select @companyname= cast (@uspcompanynameas varchar(20))46 select @address1= cast(@uspaddress1 as varchar(30))47 select @companyid = isnull(max(companyid),0) + 1 from companymaster48 49 IF exists(SELECT * from companymaster where companyname=@companyname)50 begin51 Select @frmErrorMessage = 'Record With Company Name ' 52 + @companyname + ' is Already Exisiting For The Company Name ' 53 return -954 end 55 56 -- the following codes inserts 57 begin transaction58 INSERT INTO companymaster59 ( companyname, address1)60 VALUES (@companyname,@address1)61 commit transaction62 63 select @RETURNVALUE = 064 select @RETURNID = @companyid65 66 end67 68 69 -- the following codes edit/updates 70 begin71 UPDATE companymaster 72 SET companyname=@companyname,73 address1=@address1 74 WHERE companyid =cast(@uspcompanyid as int)75 76 select @RETURNVALUE = 077 select @RETURNID = cast(@uspcompanyid as int)78 end79 -- the following codes delete 80 begin81 DELETE companymaster WHERE (companyid = @companyid)82 end 83 84 END 85 Pls help me and modify my code accordingly with ur suggestions who know the stored procedure very well.First read what i want then give reply.
Hi Smart Folks, My SQL Server-based app will require generating a few tables at run-time, and, possibly, a new small database. Again, this is at run-time. Any advice on this? Should I build the functionality from the app, having my code generate all of the commands on the db to create what I need, or should I rely on SQL Server functionality (Scripts? SPs?) to do so. I am sure there is trade-off in one appraoch versus the other - I could use a tour of the trade-offs. Thanks all! DF
My output is depends on the dist selection so made procedure
alter procedure LAT_TEST_DYNAM0 @dist_id int as begin create table #temp (pincode varchar(10) ,latitude numeric(18,10),longitude numeric(18,10) ,descp varchar(5000)) if @dist_id!=0
[Code] ....
Myself doubt is when @dist_id is null or "0" how to show default value ?
Now Sql Function can not modify data as Sql Procedure like other database, it's very troublesome at most case! in most case, Sql Function is used to improve code structure then it can be maintanced easy! BUT only because it can not modify data, there are 2 troublesome way:
1. Make all callers in the path from Sql Functions to Sql Procedure. and the coder will cry, the code will become very confusional , and very difficult to maintance.
2. Divide the Sql Function into a thin CLR wrapper to call a Sql Procedure, can only use another connection, BUT can not be in the same transaction context And the code is ugly and slow.
You should not give limitation to Sql Function, should just limit the using context of Sql Function!
The sql code is more difficult to read and maintance than norm code(C#), then the improving code structure and readability should be one of your most important task, that's why microsoft!
I have a concated code from excel when I have to pick some values for db update, the problem is when one field is empty, this field is date type and I don't now how can I validate if UserDate_02 field is null or not, I get it from a cell in excel and later when I get all the code I update the db, this is the line :
UPDATE ITEMS SET UserField_01='AA',UserDate_01='01/28/2014',UserYesNo_01=1,UserDate_02=''WHERE LotNumber='134034143017297'and ItemCode='G22221'
OK, I use asp.net membership and have created a new table that links together related users by use of the uniqueidentifier field as a foreign key. However, it is possible to link to a not-yet existent user (by their email) so that when that user creates an account and gets a guid, it will be updated into my table of related users and finalise the link. Trouble is, I'm trying to stop people adding the same "pending user" multiple times, so in my BLL logic I look for the entered email address for the current user and I want to check on the foreign key (the GUID field) so that I can tell the user that they've already added this user, but they haven't signed up yet (if they haven't got a foreign user key with a guid in it, they haven't signed up yet). However, when I check the foreign key guid value (shows as null in sql enterprise manager) for null values, it never goes down the "true" logic channel... what I mean is that I've debugged it, hovered over the item I've read (it says it is system.dbnull, which it is) and yet when I do "isDBNull(myGUID.Value)" it never equates to true! Why not?
I have one requirement where i have multiple tests conducted on different dates where i have to calculate last 'x' no of tests
Test Date Test Seq Subject
1/12/2014 1 English
[code]....
If i enter @testcount=2 then it should pull the data for only data related to test date 1/12/2014 & 10/06/2014...Above data is only sample data but logic should be dynamic..
Has anyone been successfull in creating a Web Test with Team System to test a Reporting Services report? I can record the test just fine but I can't run the test without errors being reported. I suspect that the session state has to be parameterized but I have no clue how to do this.
Why is this so hard? Why aren't there samples for this kind of thing? I've been all over the SSRS and Team Test forums and the MSDN site and can't find anything about Reporting Services reports being tested with Team System Web Tests.
If this post belongs somewhere else I appologize. I have spent several days trying to solve this problem with no luck. My site is online. Hosted at NeikoHosting. I can connect to the database remotely when adding a datacontrol. It tests fine. But when running the page it won't connect. Even if I go in and change the Web.Config connection string to a local Data Source provided to me by Neiko, it still won't work. It just won't connect. Here are the two connection strings in the Web.Config, minus my login info: Only the remote string will pass testing. Neither works on the site. <add name="yourchurchmychurchDBConnectionString" connectionString="Data Source=MSSQL2K-A;Initial Catalog=yourchurchmychurchDB;Persist Security Info=True;User ID=me;Password=pwd" providerName="System.Data.SqlClient" /> <add name="yourchurchmychurchDBConnectionString2" connectionString="Data Source=66.103.238.206;Initial Catalog=yourchurchmychurchDB;Persist Security Info=True;User ID=me;Password=pwd" providerName="System.Data.SqlClient" /> Here is the stack trace, if that helps.

With a Gridview Control, I set the SqlDataSource to be a stored procedure in a Sql Sever database. Using the wizzard to configure the datasource, the test returns lots of rows. After completing the wizzard, the gridview control does not show the column names in the VS2005 designer. For the gridview column headers the values are Databound Col0, Databound Col1, Databound Col2, ....) This tells me I have a problem. I tried the same thing with a simpler stored procedure. This test stored procedure does not call anything else, takes several input parameters, returns rows. The column names show in the gridview control as expected. So I am trying to figure out why the first case of gridview with sqldatasource is not working and the second case works . The stored procedure that is not working with my gridview calls multiple inner stored procedures and has #TEMP tables. My complex stored procedure ends with Select * from #Temp. Could the calling of other inner stored procedures and use of #temp tables contribute to the problem? If yes then what is the strategy for using a gridview and loading it with the data that the complex stored procedure returns?
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
Using a 32-Bit SQL Server 2008 Express on my LOCAL PC. I downloaded the Advantage 8.1 OLE DB Provider and created a linked server to a REMOTE Advantage 8.1 database server. There is no data dictionary on the Advantage server.
Here is my linked server:
EXEC master.dbo.sp_addlinkedserver @server = N'1xx.1xx.xx.1xx', @srvproduct=N'Advantage', @provider=N'Advantage OLE DB Provider', @datasrc=N'1xx.1xx.xx.1xxeccET', @provstr=N'servertype=ads_local_server;tabletype=ads_cdx;'--tabletype=’ADS_ADT’ (this test works too) EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'1xx.1xx.xx.1xx',@useself=N'False',@locallogin=Null,@rmtuser='adssys',@rmtpassword=Null
Testing the link succeeds with above. Using “ads_REMOTE_server” instead of “ads_local_server” and the test fails. Here is my problem, using the following queries will not work. Perhaps it’s a permissions issue? When I specify my local credentials for the remote server in the linked server it still does not work.
SELECT * FROM OPENQUERY([1xx.1xx.xx.1xx], 'SELECT * FROM ActType')
OLE DB provider "Advantage OLE DB Provider" for linked server "1xx.1xx.xx.1xx" returned message "Error 7200: AQE Error: State = HY000; NativeError = 5004; [Extended Systems][Advantage SQL][ASA] Error 5004: Either ACE could not find the specified file, or you do not have sufficient rights to access the file. Table name: ActType SELECT * FROM ActType". Msg 7321, Level 16, State 2, Line 2
An error occurred while preparing the query "SELECT * FROM ActType" for execution against OLE DB provider "Advantage OLE DB Provider" for linked server "1xx.1xx.xx.1xx".
Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here: Function Main() on error resume next dim cn, i, rs, sSQL Set cn = CreateObject("ADODB.Connection") cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>" set rs = CreateObject("ADODB.Recordset") set rs = DTSGlobalVariables("SQLstring").value
for i = 1 to rs.RecordCount sSQL = rs.Fields(0).value cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution rs.MoveNext Next
Main = DTSTaskExecResult_Success
End Function
This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)
Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:
public Sub Main()
...
Dts.TaskResult = Dts.Results.Success
End Class
I get the following error when I attempt to compile this:
Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.
I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script: - The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.
- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).
Given this statement:
dim cn, i, rs, sSQL
I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:
This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!
Table 1: AddressBook Fields --> User Name, Address, CountryCode
Table 2: Country Fields --> Country Code, Country Name
Step 1 : I have created a Cube with these two tables using SSAS.
Step 2 : I have created a report in SSRS showing Address list.
The Column in the report are User Name, Address, Country Name
But I have no idea, how to convert this Country Code to Country name.
I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]
Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output. When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok. When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out. I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null).... {
// I'm here!! I thought the watch says this is null??? }
Sorry if this is obvious, but I can't work this one out!!
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.
Hello, I'm using ASP.Net to update a table which include a lot of fields may be around 30 fields, I used stored procedure to update these fields. Unfortunatily I had to use a FormView to handle some TextBoxes and RadioButtonLists which are about 30 web controls.
