Hello all,
Currently i am having problem with the conversion from object to string. I am using SqlCommand to draw data from DB, and the statement i used is:
String ires = myCommand.ExecuteScalar().ToString();
and then convert ires to int by int.Parse(ires)
I have got no problem during the compilation, but it gives me the exception during the runtime...
any one got any ideas? Thanks
Does anyone know where to find or how to write a quick user defined fucntionthat will return a table object when passed the string name of the tableobject. The reason why I want dynamicallly set the table name in a storedprocudue WITHOUT using concatination and exec a SQL String.HenceIf @small_int_parameter_previous = 1 then@vchar_tablename = "sales_previous"else@vchar_tablename = "sales"Endselect * from udf_TableLookup(@vchar_tablename )So if I pass 1, that means I want all records from "sales_previous"otherwise give me all records from "sales" (Sales_Previous would last yearssales data for example).udf_TableLookup would I guess lookup in sysobjects for the table name andreturn the table object? I don't know how to do this.I want to do this to avoid having 2 stored procedures..one for current andone for previous year.Please respond to group so others may benfiit from you knowledge.ThanksErik
Hi, I am deploying my web through a web hosting services which provides SQL database support.

I have my connection string configured in my web.config as below: <add name="ArtHouseConnection" connectionString="Server=serveripaddress; Integrated Security=True; Database=arteh3_database;User Id=username;Password=password;" providerName="System.Data.SqlClient"/> <add name="ASPNETDBConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/> This is the source code where error was generated: public static class ArtHouseConfiguration { //cache connection string private readonly static string dbConnectionString; //cache data provider name private readonly static string dbProviderName; private readonly static string siteName; //initialize constructor properties static ArtHouseConfiguration() { dbConnectionString = ConfigurationManager.ConnectionStrings["ArtHouseConnection"].ConnectionString; dbProviderName = ConfigurationManager.ConnectionStrings["ArtHouseConnection"].ProviderName; siteName = ConfigurationManager.AppSettings["SiteName"]; } and finally this is the error mg I got: Object reference not set to an instance of an object.

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks
I have been working on this all day and cannot find an answer I need to convert a string to an object, a string to object of type Command Is there anyway to do this? Thank you all in advance!!!!!!!
Using OnSelected on the SqlDataSource----here is my currect code:private void On_Load(Object sender, SqlDataSourceCommandEventArgs e){if (e.Command.Parameters["@DueDate"].Value = "NULL"){e.Command.Parameters["@DueDate"].Value = "0000-00-00 00:00:00.000";}} I am trying to change the value from NULL(in a datetime field) to "0000-00-00 00:00:00.000" for use on the page.Any ideas, suggestions, or thoughts would be greatly appreciated! ,Gary"we truly fail, only when we quit."
I'm working with an SqlDataSource, and I'm just wondering how to get the data to a String if I'm sure the select statement will only return 1 piece of data. Any ideas?
hi , i have a problem i have an textarea that i want to convert to DateTime format (dd/MM/yyyy) . the data in the textarea is (dd/MM/yyyy for example 21/12/2005). i need it to add this data in sql server , in smalldatetime formation colum . plz help.
Hi folks, I'm trying to import data from a text file (UnicodeData.txt) into an SQL table. Some of the fields are unicode values (16 bits) expressed as four hexidecimal digits. I've succeeded in importing the data as character strings, but I have not found a way to convert them into numbers. (They could be stored as int or nchar.) I've tried convert(binary/int/whatever, string); E.g. select convert(int, '0x1111') from import_unicode gives the error Syntax error converting the varchar value '0x1111' to a column of data type int.
I could write code to strip off one character at a time, convert the hex digit to a decimal value, shift left, etc., but I find it hard to believe that's the best way.
Any help is appreciated. Please email answer to lars_huttar@sil.org as I don't read this board.
I am using DTS to read in a date with the format of YYYYMMDD. I am trying to convert this date to MM/DD/YYYY and then use the CDate function with the following code to load it into a Datetime column in SQL Server:
DTSDestination("DateName") = strHoldDate Main = DTSTransformStat_OK End Function
My DTS package will execute without errors, but it does not add the row. I have been successful using CDate when the source date is in the format MM/DD/YYYY.
Also, do you have any tips on how to debug DTS? How to see what's in a variable, etc.?
To start, I am NOT a SQL programmer. I have to do some minimal SQL administration (DB Creation, Backups, Security) on spatial databases that are for the most part managed by a 3rd party program. My experience with T-SQL is mostly simple tasks (i.e. Select and Update statements)..However I have been requested to calculate an ID Field using the values of two other fields. Per the request, I need to convert one field to Hex and concatenate with the second field.
ex. Field 1 + Field 2(hex string) = Field 3 Field 1 = 'FF02324323' Field 2 = 'Smith Creek' Field 3 = 'FF02324323536D69746820437265656B'
Field 1 VarChar(10) (Code) Field 2 VarChar(65) (Common Name) Field 3 VarChar(max) (ResourceID)
Spent half the day searching and have tried various forms of CAST, CONVERT, fn_varbintohexstr and others but have unable to come up with the correct combination to get what I need.
In our ERP system we have a field which is a date-picker in the user front end, but the value is stored in an NVARCHAR field and not always consistently. How can I convert this to a date (preferably in the format YYYY-MM-DD HH:MM) that I could use in a calculation?

Hi all, I defined an user string type varible in the package as AccountLen. I am trying to use this varible in the Expression of Derived Column transformation. I want to retrieve a part of column, i.e: Right(Column1, @AccountLen), this is always wrong because the AccountLen is string type. How I can convert it to the numeric so that can be used in the RIGHT function? Thanks
Hi Everyone - iam facing a small problem i want to convert an output from the context_info() which is binary to string (or int)

I am getting an issue when i try to run a package which was validated against an oracle database on windows with UTF8. When I try to run the same package(no changes, just changing the conenction parameters to point to an oracle database on UNIX with UTF16), the package fails with error saying cannot convert unicode to string for string columns. The same run through fine if I refresh the metadata against the UNIX database, but then it doesnt run against the Windows database.
Can anyone please suggest how to overcome this scenario. My issue is, I need to run my package against various database(by just pointing the database connection details) without changing anything in the package.

I have an Execute SQL Task that queries for the contents of a file (which is declared as a varbinary type). My SSIS package needs to write these contents into a temporary location, so what I do is that I pass the result into a System.Object variable. I then use that variable in a Script Task.
Problem is whenever I execute my script task and DirectCast or CType the variable to a string (which is what the contents of the file is), I get a "Conversion from type '_ComObject' to type 'String' is not valid."
I'm trying to figure out how to convert an INT so that I can add it to another string in a statement likeSELECT '<a href="http://mydomain.com/' + [IntValue] + '">' + [LinkName]Where [IntValue] is an INT field containing a folder number. I tried: TO_CHAR([IntValue, '999')but it didn't work. And I tried to find a TO_STRING function, but had no luck.Any advice to someone who is savy, but new to SQL Queries?

Hello I'm trying to write a SQL Statement along the lines of....
SELECT stringField + ' : ' + STR(decimalField) AS myField FROM tablename WHERE myCondition = myValue
Where stringField is a String field and decimalField is a Decimal Field in my Table. In this statement it converts the decimal field to a string value so that it doesn't throw a conversion error but unfortunatly it seems to round up the value to an integer value and cuts off all my decimal places.
