How To Use /Set Option To Set A Variable To Empty String
May 19, 2008
Hi,
I developed an SSIS package and I'm using the dtexec utility to run it. The package has a variable RunDate (datetime) and i want to set this value to "" (empty string) when i try to run this package using the dtexec.
Currently I'm getting an error Argument option not valid.
Thanks in advance

I created a package scope variable to use as a sql command for a data flow task. But when I click the drop down to select it, nothing appears. Anybody else have this issue and find a solution?
In the code below, the statement 'Print @Sites' prints nothing, eventhough the cursor contains 4 records, and 'Print @Site' prints theappropriate values. Can anyone see my mistake? I am attempting toprint a delimited string of the values referred to by @Sites.Thanks.Dan FishermanDECLARE SiteCursor CURSORGLOBALSCROLLSTATICFOR SELECT OfficeName FROM ClientOffices WHERE ClientID=12 ORDER BYOfficeNameOPEN SiteCursorDECLARE @Sites varchar(1000)DECLARE @Site varchar(100)FETCH NEXT FROM SiteCursor INTO @SiteWHILE @@FETCH_STATUS=0BEGINprint @SiteSET @Sites = @Sites + ', ' + @SiteFETCH NEXT FROM SiteCursor INTO @SiteENDPRINT @SitesCLOSE SiteCursorDEALLOCATE SiteCursorGO
declare @user varchar(30) = '' if(@user is not null or @user <> '') BEGIN print 'I am not empty' END ELSE BEGIN print 'I am empty' ENd
The output should be 'i am empty' but when i execute this i am getting ' i am not empty'. even i did browse through but i don't find the difference in my logic.
I used the following connection string when working with a SQL server DB locally in an ASP.NET code-behind module: dim source as string="data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|Registration.mdf;User Instance=true"
However, when I uploaded the application to a web server where my site is hosted, I spent considerable time debugging the "Cannnot establish connection" exception, I was getting.
After adding "Database=Registration.mdf;server=<server N/W address>" and removing "AttachDBFilename=|DataDirectory|Registration.mdf;" from the connection string, the connection was finally established.
Now, I have two questions: What's the difference between database and attachDBFileName options (And when should I use which)?
Secondly, why I had to add the server option, when it worked fine locally, and the application & db are located on the same web server?
I have a SQL Server table with nvarchar type column which has not null constraint. I am inserting empty string ("") from Java to the table column. When I export this table into .csv file using bcp tool, empty string gets written as NUL character. Is there any way I can bcp out empty string as empty string itself instead of NUL to the file?
Hi ng.I have a varchar field in my table, called Name.I wanna do a selection, which is ordered by whether this field is empty ornot.E.g. something like:SELECTUserIDORDER BYName <> '';- - -How can I accomplish this?TIA.Klaus.
For operands of the conditional operator, the data type DT_STR is supported only for input columns and cast operators. The expression "...see above..." has a DT_STR operand that is not an input column or the result of a cast, and cannot be used with the conditional operation.
The expression works if I replace the NULL(DT_STR, 0, 1252) with say "A" and the expression works on other non-string columns. (As in "NULL(DT_I1) : (DT_I1)100")
I am trying to change variable value at run time in ssis 2012 package using DTEXECUI utility but can not see any changes happening in config file variable value and also data is not getting populated in my table as per new variable value.
What is the right syntax or method of dynamically changing variable value either through DTEXECUI or DTEXEC command prompt command.
I need to check in my Stored procedure if the information passed is null or empty so I can decided to insert the new value or keep the old. How do I accomplish this please in T-SQL. Thanks in advance.
Hi: Trying to insert null value into sql table, but not working, if I use: if (strMyText.Length == 0) command.Parameters.Add("@Text", DBNull.Value); // or using:("@Text", null), or using:("@Text", DBNull) else command.Parameters.AddWithValue("@Text", strMyText); When I go back to table, I see the value is: 'NULL', has single quotation mark, suppose to be: NULL Where is the problem? Thanks a lot. Jt
Hi all, I have some columns in my database which allows null. I want to know if leaving the field to be NULL or storing an empty string into the field, which will take up more space?? if the field type is varchar(100)
I've have about 100 tables, for some reasons, column values that are originally NULL was inserted as emtpy string. So, I am wondering if I can write JUST ONE SQL (hopefully don't have to specify the field names in the SQL as well) for each table so that all the empty strings will be converted back to NULL.
I am using SSDT to deploy my database project. This project has a post deployment script and i am creating a new user in this post deployment script. I have used sqlcmd variable to capture the username. I am doing a null/empty check for this variable and my code looks like below.
IF (([$(UserName)] IS NOT NULL) OR ([$(UserName)] <> '')) BEGIN CREATE USER [$(UserName)] WITHOUT LOGIN WITH DEFAULT_SCHEMA = dbo; GRANT CONNECT TO [$(UserName)]; END
When i execute this, I am getting below error.
Could not deploy package.
Error SQL72014: .Net SqlClient Data Provider: Msg 207, Level 16, State 1,Line 15 Invalid column name 'User Name'.
Error SQL72045: Script execution error. The executed script:
Can we have blank value in Primary key field? Two fields are chosen as Primary Key for this table but the issue is at any given time one value will be blank when other is populated. Does sql server still order the records based on these keys? (Clustered index). Or should I just go about adding ID (identity)?
I'm doing a bcp out of a table to a file. Some of the fields in arecord may have an empty string.When I bcp out to the file and examine it, the fields that have anempty string in the database now show up in the file as having oneblank character.Why is bcp doing this? I don't want the blank character in my output.Thanks,Eric
Hello, I have a problem where I need to include data from a table where one of the joined columns can contain empty strings. The emptry string column and its related columns need to be included in the results of the query.
The Join looks like this:
SalesData.dbo.tbl_CYProcessedSales ps INNER JOIN SalesData.dbo.vw_Product_CYProcessedSalesXref xr ON ps.Prod = xr.Prod AND ps.Acct = xr.AcctCode INNER JOIN TxnRptg.dbo.vw_NetNewRevenueUnion nn ON xr.BillingType = nn.BillingType AND xr.ProdGroup = nn.Product AND xr.AcctCode = nn.AcctCode
The problem occurs on the xr.BillingType = nn.BillingType portion of the join. the nn.BillingType can contain empty strings. I've tried a LEFT join to vw_NetNewRevenueUnion, but this has not worked.
In vw_NetNewRevenueUnion, BillingType becomes an empty string within a CASE statement if BillingType is NULL. I've thought about using something like 'All' in the ELSE condition, and doing the same in the vw_Product_CYProcessedSales view just so I don't have to deal with an empty string.
If I were not to do that, is there some way I can handle the empty string issue within the join so that empty string records will be included in the query results?
I am using a SQLDataSource with the following Select query. If the "spouse" values are not in the database, I get the HTML non-breaking-space character back, rather than an empty string.
SelectCommand="select applicant_id, (applicant_last_name + ', ' + applicant_first_name) as applicant_name, CONVERT(varchar(10), applicant_dob, 101) as applicant_dob, applicant_ssn, (spouse_last + ', ' + spouse_first) as spouse_name, CONVERT(varchar(10), spouse_dob, 101) as spouse_dob, spouse_ssn from applicant where applicant_last_name like '%'+@last_name+'%' order by applicant_last_name"
Hi all,I have this code that I use for my Search function:SELECT DISTINCT [MUSIC_TITLE], [MUSIC_ORIGINAL_SINGER], [MUSIC_PERFORMER]FROM t_musicWHERE (@MUSIC_TITLE IS NULL OR [MUSIC_TITLE] LIKE '%' + @MUSIC_TITLE + '%') AND (@MUSIC_ARTIST IS NULL OR ([MUSIC_ORIGINAL_SINGER] LIKE '%' + @MUSIC_ARTIST + '%' OR [MUSIC_PERFORMER] LIKE '%' + @MUSIC_ARTIST + '%')) But right now if I don't enter anything in one of the textbox (2 have two, either of them can be left empty), the above Sql statement doesn't return anything since ADO.NET can't tell an empty textbox and treat it at null... So anyone please help me how to detect an empty textbox and set that to null for the above SQL statement to work. (It work in SQL Manager Studio, when I set one of the parameter = null.) I'm very new to ASP.NET stuffs, so if someone can help me to convert that function to code-behind and help me to call it from the .aspx, that would be even better as I don't want to put the code in my .aspx page... But I'm not quite there yet. Thank you all,Kenny.
I am using the following query to calculate date differences:select ..........DATEDIFF(d, recruitment_advertising.advertising_date, career_details.RTS_Email AS Datetime) AS Ad_to_RTS_days FROM .....I have stored all my dates as NVARCHAR because of the issues with localization.If the value is an empty String my output is eg: -38700. which is way off and incorrect. Some of the values in my table are NULL and they produce the correct result.Is there a T-SQL statement to replace empy Strings with the NULL value in my tables.I'd like to use it as a trigger when inserting or updating to convert empty strings to NULLbefore the values are inserted.Thanks guys.
Has anyone find solution for this problem. i also checked http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=298056&SiteID=1 and http://blogs.conchango.com/kristianwedberg/archive/2006/02/22/2955.aspx
Suppose have a Dimension table
DimColor ---------------------------- ColorKeyPK(smallint) ColorAlternateKey(nvarchar(30)) -1 UnknownMember 1 2 Blue 3 Red 4 Black
Color with the ID 1 is empty string
FactOrders --------------------------- OrderID Date Color Quantity
OrderID = 1 Color = 'Black' Quantity = 10 OrderID = 2 Color = 'Red' Quantity = 20 OrderID = 3 Color = '' Quantity = 10 OrderID = 4 Color = 'Blue' Quantity = 5 OrderID = 5 Color = Black Quantity = 10
When i use the Lookup transform it cannot find the ColorKeyPK
The result of the Lookup transform is. ------------------------------ OrderID = 1 Color='Black' ColorKey=4 OrderID = 2 Color='Black' ColorKey=3 OrderID = 3 Color='Black' ColorKey=NULL ----> This is the problem Lookup cannot find empty string. It should be 1. OrderID = 4 Color='Black' ColorKey=2 OrderID = 5 Color='Black' ColorKey=4
This seems to be a rather old problem (http://www.themssforum.com/SQLServer/Does-empty/) but I couldn't find an answer yet.
The problem is: I have two tables t1 and t2 where t1 is a staging area of t2. t1: (id int not null, phone varchar(30)) t2: (id int not null, phone varchar(30))
Data in t1: (1, '') <- empty string Data in t2: (1, ' ') <- a blank
Comparing t1.phone with t2.phone results in equality which in my opinion isn't correct.
The question ist: How can I change the behaviour of SQL-Server to result in inequality so that the change in my staging table is detected correctly?
