Hi, I'm pretty new to ASP.NET and VB, but I'm working on a project which is essentially a staff directory. Using VS 2005, I've setup a basic grid view which connects to an object which connects via a data layer to a SQL database with Name, Surname, Email, Extension No and Department fields. I have it working so that if a user enters a name and surname for example, it will return all records with either the name matching or surname matching input parameters. What I want to do is to set up a SQL query which is: SELECT * FROM records WHERE (Name LIKE @Name) AND (Surname LIKE @Surname) AND (Email LIKE @Email) AND (Dept LIKE @Dept) so that if the user only enters the first name and surname for example as above, it ONLY returns the record which matches the first name and surname and not all records with either/or. One way I've thought of to do this is to convert the empty fields to "Nothing" so that it fullfils the search parameter for the empty fields. If someone can explain how to do this, or can suggest a better way, I'd be grateful. Cheers, Tom
Dear All, I have created a table in my SQL server database, the problem i am facing is my insert query fails if i leave any form field empty (leave it blank). On my back-end table, only one field is mandatory, and others have been set with the constraint "allow null". As per our business requirement, except one value is complusory while others are optional. If I enter all values in the form it works perfectly fine. Can you see in the code below - where am i possibly going wrong ? <script language="VB" runat="server" > Sub Page_Load(Src As Object, e As EventArgs) If Page.IsPostBack Then Dim ConLath As SqlConnection Dim comLath As SqlCommand Dim insertcmd conLath = New SqlConnection("Data Source=SQLas;Initial Catalog=settle;User ID=sa;Password=password") ConLath.Open() insertcmd = "Insert into His_set values (@t_d,@s_p,@p_s,@v_oq,@i_oq,@v_qn,@i_qn,@v_qw,@i_qw)" comLath = New SqlCommand(insertcmd, ConLath) comLath.Parameters.Add(New SqlParameter("@t_d", SqlDbType.DateTime, 12)) comLath.Parameters("@t_d").Value = trade_date.Text comLath.Parameters.Add(New SqlParameter("@s_p", SqlDbType.Decimal, 8)) comLath.Parameters("@s_p").Value = sett_price.Text comLath.Parameters.Add(New SqlParameter("@p_s", SqlDbType.Decimal, 8)) comLath.Parameters("@p_s").Value = post_close.Text comLath.Parameters.Add(New SqlParameter("@v_oq", SqlDbType.Int, 8)) comLath.Parameters("@v_oq").Value = vol_oq.Text comLath.Parameters.Add(New SqlParameter("@i_oq", SqlDbType.Int, 8)) comLath.Parameters("@i_oq").Value = oi_oq.Text comLath.Parameters.Add(New SqlParameter("@v_qn", SqlDbType.Int, 8)) comLath.Parameters("@v_qn").Value = vol_qn.Text comLath.Parameters.Add(New SqlParameter("@v_qw", SqlDbType.Int, 8)) comLath.Parameters("@v_qw").Value = vol_qw.Text comLath.Parameters.Add(New SqlParameter("@i_qn", SqlDbType.Int, 8)) comLath.Parameters("@i_qn").Value = oi_qn.Text comLath.Parameters.Add(New SqlParameter("@i_qw", SqlDbType.Int, 8)) comLath.Parameters("@i_qw").Value = oi_qw.Text Try comLath.ExecuteNonQuery() Catch ex As SqlException If ex.Number = 2627 Then Message.InnerHtml = "ERROR: A record already exists with " _ & "the same primary key" Else Message.InnerHtml = "ERROR: Could not add record, please " _ & "ensure the fields are correctly filled out" Message.Style("color") = "red" End If End Try comLath.Dispose() ConLath.Close() End If End Sub </script>
Hi all. I was wondering if there was a way to supress the error messages while designing an SP in Enterprise Manager, such as if you have a column name in your T-SQL that doesn't exist in a table and you click 'Apply' or 'OK', Ent Mgr throws an error 'Invalid column name ...' and you cannot save the SP.The reason I need to do this is because I am writing a large data-transforming SP. The SP takes data from an old, un-normalized DB and converts the data into a new, normalized format. I need two temp fields in three tables. These fields will act as references to bridge the data transformation from the old data to the new. So, I will create the temp fields in one SP, run the data transformation in a second SP, and drop the fields in a third SP. Note that I split out the adding and dropping of the fields because of experimenting with some debugging of the SP failure.Which brings me to my second issue. If I run the SP to add the temp fields, the SP runs fine and the fields are added. Then I can open the data x-fer SP, develop and debug it, and click 'OK' or 'Apply'. No problem. Then, I can run the SP to drop the temp fields.However, I'd like to have everything in one SP. This way, when I need to transform the production data, I can just execute one SP all under the scope of one BEGIN/COMMIT TRAN transation. Assuming that I have everything in one SP: if I comment out the lines that drop the temp fields, then the SP runs fine. If I uncomment the lines that drop the temp fields (at the end of the SP), then the SP fails, with and error in the middle part of the code that does an INSERT INTO <temp_field_created_in_the_SP>.Why would the SP fail to insert into temp fields if I uncomment lines of code at the end of the SP to drop those fields. Does it have to do with the scope of the transaction? I even tried to COMMIT the main transaction that adds the fields and transforms the data, and wrapped the dropping of the fields in a separate transaction. It still errors out.Here is the code to add and drop the temp fields:IF NOT EXISTS (SELECT * FROM syscolumns WHERE ID=OBJECT_ID('Customers') AND NAME='TEMP_ad_addr') ALTER TABLE Customers ADD TEMP_ad_addr VARCHAR(80) NULL.<transform all data code>.IF EXISTS (SELECT * FROM syscolumns WHERE ID=OBJECT_ID('Customers') AND NAME='TEMP_ad_addr') ALTER TABLE Customers DROP COLUMN TEMP_ad_addr
i want to check if one of the fields is empty. however i cant seem to get it working string strSQL = "select * from 15Course_Listing where Package_listingNo =''";
it does not return anything, however i have empty fields in package_listingNo
i have been trying to get around this for some time and its killing me. need help please
Hello! I have a web form in VB.NET & ASP.NET 1.1, with data being saved to a SQL 2005 database with multiple tables. The primary key on all these tables is a unique identifying number that the user enters. However, one record in this database (across all tables) has no identifier. All other information seems to have saved without problem, but there's no identifier, which is very wierd for several reasons: 1) the form should not allow the user to proceed without it; 2) all the tables in the database do not allow nulls for the column, and 3) it's the primary key! Any thoughts on how this might have happened? Thanks! Kaiti
I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.
Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.
Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.
What do I do now to get around this? How do I fix it?
Im ripping my hair out here.I need to access the field in a datasource control of use in non presentation layer code based actions.I know the I can use a code base connection and query but I dont see why i need to make two trips the the DB when the info is already available.The datasource is attached to a details view control and the details view control is nested in a loginview controlI've tried defining but all I can get in the header name of the field but not the dataitem, the dataitem causes an error help please jim
If I have a column named "Login" in a SQL Table (I am sharing with another application) that I am using a stored procedure to acquire the information from, how can I trranspose its name to match code already written in a Web App to get the data. There is a web app already created that has the followig code to get the data from the database Dim strSQL ast string = "UsersSelectCommand" intLoginID = objDataReader("LoginID")
My stored procedure is the following: CREATE PROCEDURE UsersSelectCommand/* ( @parameter1 datatype = default value, @parameter2 datatype OUTPUT )*/AS Select Lastname, FirstName, Login from Users Order by LastName GO The stored procedure will return "Login" instead of "LoginID" that I am wanting. How can I modify the Stored Procedure to change the LoginID to Login.
I'm trying to do a simple update like I have done countless timesbefore.However, when I update the empty fields in this table it places a -1into the field rather than the enterred value.It is indexed with duplicates allowed. It says that zero lenght isset to yes.What can I do about this?if Request.form("ouserid") <> "" Thenvar2 = " and userid = '" & Request.form("ouserid") & "' "Elsevar2 = " and userid is null "End ifif Request.form("orepid") <> "" Thenvar1 = " repid = '" & Request.form("orepid") & "'"Elsevar1 = " repid is null "End if"Update [Website Settings] set userid = '" & REquest.form("userid") &"' and repid = '" & Request.form("repid") & "' where " & var1 & var2& var3Thanks!
I am going crazy trying to figure out how to do this. I have a flat file which I am massaging the data and loading into a table here is an example of a line out of the flat file:
My problem is that I have one field which is this address in a concatinated form. The fields that do not apply to this entry are suite#, floor# and other columns which are designated by the "" characters. The final concatinated addres field looks like this:
"550""""N""FAIR OAKS"""
I would like to remove the "" characters in the concatinated string. I just don't know the best way to do this? I was told DTS had a way of removing the "" from the flat file source. Since I have not used DTS extensively I am not sure if this is true. I was wondering how in SSIS I could go about removing the "" marks without removing the "" say if someone is quoted eg. John said "This is only a test". Removing the quotation marks in this instance would be changing the data. I am not sure how to do this and any help or advice is greatly appreciated!
Does anyone have already made an application that writes some data into the EDB Pocket database ? I´m trying to insert a record with a empty FILETIME field and I´m getting the Error 87 (INVALID_PARAMETER), I´ve tested with some date in the field and the record is added sucessfull, it seems that the database doesn´t accept anymore empty FILETIME fields? Is it true? I didn't find anything in the docs.thanx in advance.
So I have an MDX query in an SSRS data set. Here is my MDX query:
Code SnippetSELECT { [Measures].[Gross Sales Amount USD], [Measures].[Net Sales Amount USD] } ON COLUMNS, { ([Promotion].[Media Property].[Promo Code Description].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOMEMBER(@BeginDateConvert, CONSTRAINED) : STRTOMEMBER(@EndDateConvert, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@PromotionMediaProperty, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( { [Promotion].[Campaigns].[Campaign].&[Paid Partner] } ) ON COLUMNS FROM ( SELECT ( { [Products].[Product Line].[Line].&[Merchandise] } ) ON COLUMNS FROM ( SELECT ( { [BusinessUnit].[Business Unit].[Product Business Unit].&[40] } ) ON COLUMNS FROM [Net Sales]))))) WHERE ( [BusinessUnit].[Business Unit].[Product Business Unit].&[40], [Products].[Product Line].[Line].&[Merchandise], [Promotion].[Campaigns].[Campaign].&[Paid Partner] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
This query returns 4 fields. Media Property, Promo Code Description, Gross Sales, and Net Sales. For the given query the measures are empty or null. I do not want any data to show up when the measures are null so I put in NON EMPTY clauses before the COLUMNS and before the ROWS. So now my query looks like this: (I only added the NON EMPTY clauses)
Code Snippet SELECT NON EMPTY { [Measures].[Gross Sales Amount USD], [Measures].[Net Sales Amount USD] } ON COLUMNS, NON EMPTY{ ([Promotion].[Media Property].[Promo Code Description].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOMEMBER(@BeginDateConvert, CONSTRAINED) : STRTOMEMBER(@EndDateConvert, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@PromotionMediaProperty, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( { [Promotion].[Campaigns].[Campaign].&[Paid Partner] } ) ON COLUMNS FROM ( SELECT ( { [Products].[Product Line].[Line].&[Merchandise] } ) ON COLUMNS FROM ( SELECT ( { [BusinessUnit].[Business Unit].[Product Business Unit].&[40] } ) ON COLUMNS FROM [Net Sales]))))) WHERE ( [BusinessUnit].[Business Unit].[Product Business Unit].&[40], [Products].[Product Line].[Line].&[Merchandise], [Promotion].[Campaigns].[Campaign].&[Paid Partner] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
Adding the NON EMPTY returns nothing... not even field names. This is a problem because, I have a table in the report that looks at this data set and when there are no fields, the report can't run.
How can I still have NON EMPTY functionality and still show the fields? Is this a problem in SSRS?
I have several reports for which the user has asked to have an optional muti-value parameter. They want to be able to select zero, one, many, or all values in the parameter list. The parm list is created through a query and the values are not static.
I would like to allow the user to leave the muti-value field empty if they want to allow all values to appear on the report. I've read some discussion about populating a multi-value default with the same query that produces the multi-value list values - presto, everything is selected. However, this is not a desirable solution for me because I "echo" the users parameter selections in the report heading. Selecting all values (and some parms have a lot of values) would cause the "parm feedback" section to grow large and unreadable.
In short, I don't want to tell the user they have to select everything when they really want to select nothing.
Is there any way to have a muti-value parm that won't insist the user select one or more values?
i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:
Code:
IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))
Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table
but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"

I have a requirement where i have to insert empty string in column whose datatype is decimal.
I have to replace the column value if it is null then insert it as ' '.
Obviously its generate error msg for conversion, is there any workaround for this. I cannot add 0 or other value as this column is used to generate some output value.
IIF(Column1 IS NULL, ' ', Column1))
I used TRY_PARSE but it insert null value if there is conversion error.
I've a weird problem in my application. In of the pages, while trying to update the text box "Name", when I enter Linda's test, it gets saved as Linda''s test. I'm not sure if this is a problem due to SQL server. When I look at the stored procedure, I don't anything different. Also, when I update the table directly in SQL Server, the result is displayed in single quote. But if I update the field thro' the application, the returned name is with double quotes instead of single quote. Has any of you faced problems like this? What am I missing? What do I need to do to get the name saved the way I entered (with single quotes) instead of double quotes?
Hi, What is the difference updating a null value to char/varchar type column
versus empty string to char/varchar type column?Which is the best to do and why? Could anyone explain about this?
Example:
Table 1 : tCountry - Name varchar(80) nullable Table 2 :tState - Name char(2) nullable Table 3 :tCountryDetails - countryid,state (char(2) nullable) - May the country contain state or no state So,when the state is not present for the country ,i have two options may be - null,'' tCountryDetails.State = '' or tCountryDetails.State = null?
Hello, My company Intranet has a form that agents can use to post their comments about the company to upper management, but our customer service department would like to modify the form so that the agent has to pick from a comment type. The dropdown options on the form will be as follows: ComplimentsComplaintsGeneral CommentsSuggestions Each dropdown option has a designated table in a SQL DB.Using postback on the same page, I need to change which fields of the form are visible based upon which dropdown selection the user chooses, and I need the fields to then be inserted into the table that corresponds with the dropdown selection item. For example: If the Compliments dropdown selection is picked, I need a text box to show for the user's location, the name of the customer, account number, and the message box. Once the submit button is clicked, the characters in these boxes need to be inserted into the Compliments table using its data adapter. However, if the user selects Suggestions, the name of the customer and the account number should not be visible, since these fields do not exist and when the submit button is pressed, the Suggestions table should be updated. If you need more information, I will provide whatever is needed. As always, thanks for everyone's assistance. Chris
Hi, I got a problem. I installed Microsoft SQL Server Management Studio Express 2005 version. And I created a Compact database. I created an connection in SSMSE to connect the database and opened a query form. then, i run the following sql:
Select * from Table1
It returned 3 records to me. After that, I used program to insert record into this table. Then i ran this sql again, it still show me 3 records. I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.
Why? It's very strange and difficult to operate, right? Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?
Hi everyone, What is the main difference between first form normalizations and second form normalization ? In my opinion, they are both generated for the same operation which is to prevent redundancy(in other words; duplication of data in several records). So would you please explain it to me ?

I am working on a query application, and I want to do syntax validation before I submit the dynamically sql to the database. The expression will include ANDs, ORs, IN, (,),>,<,etc. Anyone done this already? any code snippets?

Now to test errors comming back on the aueue i sed to make the xml tags wrong, then the target would send a error back on the queue with xml validation failed (both queues have validation well_formed_xml). However now in testing i cannot even send the message i get an invalid xml error straight away, i am not sure why this is , i know the xml is not valid but the send used to work and i would get an erro rback, as the xml is validated by the ttarget, but this no longer works it ails strainght away, with no thing in any queue. What could be causing this ?
I think I have read online a recommendation about not using XML VALIDATION in a production environment, due to performance reasons. Is it recommended using other that NONE validation in production, and is there available documentation for a scale that grades performance hits for various types of validations?
Afternoon all,I want my SQL SP to do some validation on a form submit to do the following before committing to the table.If email address (txt.Email.Text) doesn't exist in the table, commit values.if email address (txt.Email.Text) does exist and option (radOptions.SelectedValue) equals 1, print message to say 'you're already subscribed'if email address (txt.Email.Text) does exist and option (radOptions.SelectedValue) equals 0, print message to say 'you're not subscribed'if email address (txt.Email.Text) does exist and option (radOptions.SelectedValue) equals 1 or 0, update row to 0 or 1 (depending on subscribe or unsubscribe - 1 = subscribed, 0 = unsubscribed) The simple SP is currently:ALTER procedure [dbo].[sp_customerSignups]@name varchar(50),@email varchar (50),@subscribed intasBEGININSERT INTO tblCustomerSignups(Name, EmailAddress, Subscribed)VALUES(@name, @email, @subscribed)END Does anyone have the correct syntax for this?Thanks,Brett
When I create and query the XML file using LINQ, everything works just fine. I also get no compilation errors.
