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 have a problem with casting a string number to int. for exmaple i have the number '0110' (string) and i would like it to be 110. or '0001' to be 1. i tried to do: cast(MyNUM as int) . but i get "Syntax error converting the nvarchar value 'O322' to a column of data type int."
I created an SSIS package that pulls in legacy data from a DB2 AS400. There is an In Date field that is stored on the AS400 as OdbcType.Date or DATE. However, when I use SSIS to pull in the data, SQL wants it to be a string so I gave up and let SQL have it's way.
Now in my SELECT statement, I have this:
SELECT TLMST.TLNUMBER, TLMST.DOGNAM, BRDMST.BRDesc, TLMST.INDT FROM TLMST INNER JOIN BRDMST ON TLMST.BRDCOD = BRDMST.BreedNumber WHERE (TLMST.INDT >= @startdate) AND (TLMST.INDT <= @enddate) ORDER BY TLMST.INDT, TLMST.TLNUMBER
Because I see the dates stored in TLMST are yyyy-mm-dd format, this is not working. It is not pulling any records. I tried to use the CAST statement but I keep getting errors about casting from a string to a date and data overflow errors.
Should I go back and re-do the SSIS or is there a way to pull the records for this? Thanks for the information
My source file is showing column 10 as string. My destination table is datetime. I am using the derived transformation with a conditional statement. How do I convert the value from string to date. Everywhere I try the (DT_DATE) I get an error.

I am attempting to convert an integer value to a string using the Derived Column transformation with the following expression on the field: (DT_STR,10,1252)prod_id
prod_id is an integer. I was able to do this before however, in the past couple of days, this has failed with the following error: "An error occurred while attempting to perform a type cast."
To my knowledge, I have not changed anything about this particular data flow within the past couple of days. I have verified that the value is coming in as an integer.

This is because a date of 04/16/2014 will show as 160416 in the first part of the field I need to parse it out of, thus becoming 04162014.
From there I then need to convert this "date" into a legitimate SQL datetime type, so that I can then run a DATEDIFF to compare it to when the record was actually entered, which is a separate field in the table, and already in datetime format.
When I use the below statement, I am getting the message that, "Conversion failed when converting date and/or time from character string."
I am getting an invalid cast specification when I call dtexec and try to /SET a user variable within the package that is defined as a string data type. Is there any solution to this? I have tried passing the GUID with {} w/o {} w/ '' w/ "" etc.. many variations... and still get an invalid cast specification. Is there a data type that I need to set the User variable to besides String? The User Variable is used to Select records from a SQL data source where the GUID is stored. I do not have an option of GUID data type for a User Variable.
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.
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 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
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?
