Integration Services :: Empty String Is Showing As NULL Value In Database?

Oct 8, 2015

In my source table, I have columns FirstName and LastName, both of datatype nvarchar. In my dataflow, I created two new derived columns mapped to these two columns. When pushing data to the source, I noticed that the FirstName column had a value of NULL while LastName was just an empty string (for rows that did not have any value).

My question is, why my source table column FirstName is showing a NULL value when the derived column datatype is string and the source is string? It should just be showing an empty string right?

Integration Services :: How And Using Which SSIS Component To Change Empty String Value To 0

Oct 4, 2015

I have my SSIS package that reads elements from a Sharepoint list to a SQL table. The data type of my source is string and the destination is integer. The source column can sometimes be an empty string "" (not a required column)

Which expression to use and "where" or "what" SSIS component can I add this expression to? Like I know that I can use the "Conditional Split" to filter the data so for my expression which component can I use?

HELP : Empty String To Null Conversion By SQL

Nov 10, 2005

Hi folks,

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.

Detect And Convert An Empty String (from Textbox) To Null?

Jun 9, 2007

 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.

Converting Empty String To Null When Inserting/updating

Mar 10, 2006

    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.

Anyway To Check If A Text Field Is Blank (not Null But Just A Empty String '') ?

Oct 27, 2004

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:


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"

Derived Column Logic To Replace Empty String With Null?

Nov 7, 2006

Ok.. so I have a fixed position data feed. I read the file in as just whole rows initially, process a specific position and evaluate a conditional split to determine direction of the file for proper processing (file contains multiple recors with different layouts). This all works fine. I then use the derived column feature to process all the columns.

Most of the columns are as simple as SUBSTRING(RecordData,1,10) for example to get the first column. This all works for string data. I then have a column that is a date field. The problem occurs that the code SUBSTRING(RecordData,20,10) returns either a date or empty set of data if no date was in the original file. When this gets sent to the OLEDB connection (SQL Server 2005) into the date field it fails. If the record has a date it works, but if it is empty it fails the insert.

I tried to replace empty strings with NULLs with this code. REPLACE(TRIM(SUBSTRING(RecordData,20,10)),"",NULL(DT_WSTR,10)). This does not work. So my question is how do I bring a date field from a fixed flat file into a SQL datetime field using a derived column? More specifically is how do I set it to NULL if its empty data? When I use the above code it inserts all the rows from the file, but it sets all rows to NULL not just the empty ones.

Default To NULL Instead Of Blank/empty String During Flat File Import

Aug 15, 2006


In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.

The table may contain column that are NULLable BUT there is NO DEFAULT for them.

If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?

I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:

1- set the DEFAULT(NULL) for EVERY column that needs this behaviour

2-set up some Derived Column option in the package to return NULL if the value is missing.

Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.

What Is The Difference Between Updating Null Value Vs Empty String To Varchar/char Field?

Aug 29, 2007

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?


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

Integration Services :: SSIS Insert Non Null Value Into Null Rows

Jul 15, 2015

I have a flat file with the following columns

SampleID   Rep_Number   Product  Protein   Fat   Solids

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.

Integration Services :: SSIS Balanced Data Distributor Control Not Showing In VS

Oct 25, 2015

I installed the Feature Pack Balanced Data Distributor control on my PC to use with SQL Server 2014 64 bit.  I have used the control with SQL Server 2014 and SSDT so I was familiar with the process. Unfortunately, I cannot get the control to appear in the toolbox. No error messages appear, BDD just doesn't appear in the toolbox.  I have tried un-installing, reinstalling, installing SQL Server 2014 SP1, installing again, rebooting a number and nothing works.  The control just does not appear in the toolbox. It doesn't not appear when I go to choose items either. What does it take to get BBD to appear in the SSIS Toolbox for VS?

Reporting Services :: Hiding Column Based On A String Value But Showing It For Others?

Nov 20, 2015

I need to hide a column just for certain values from a table like contract decorators I tried using

=IIF(Fields!MainTrade.Value = "Contracts Decorator, Bricklayer", True, False)

But it just hid the column for all values, then i tried this but it doesn't seem to work (Think it's not correct though)

=IIF(Instr("Contracts Decorator, Bricklayer","," & Fields!MainTrade.Value & ",") > 0,true , false).

Below is the table and the highlighted column i am trying to hide just for those two fields. The table has a page break so that it would be displayed on a different page for each value, but i'm not sure it is possible as i have only done it for integers and rows before.

Transact SQL :: Database Null Value And String Null

Oct 27, 2015

We have a case where in we should show date based on conditions for e.g if we had a column defined as

col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition

Normaly date values are stored here e.g under col 20150901 .

when col>'20150901' then 'NULL'
else col
end as Derivedcol

Note this is an extract process and we are presenting data by pumping the data in a table .

Now there is another similar column -colz varchar(10)  which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.

So whats the difference between database null and string null ?

 How can we show database null for the case condition instead of string "null"?

When i deploy the solution to production the data in the configuration table is different obviously but i get a connection error that saying that it try to connect to my dev server.why?

Integration Services :: Excel Source On SSIS 2008 Brings Null Values

Apr 20, 2010

I'm trying to import some XLS files that I receive from some suppliers. The problem is that every time they send some columns with text values but formatted as number. When I read those columns with SSIS Excel Source, they come all with null values.

I don't want to change the columns data types every time, so I would like to know if there's a way to bypass the column types that are already there.

I tried to use both the Jet driver and the Office 12 driver. I've already used the IMEX=1 on ExtendedProperties too with no success. Is there a way to force reading the columns as text, even if they have data types assigned to them?
