l've 2 variables A & B from source database which i used to calculate C with the following formula, i.e.
C = 100 * A/B
In case of B = 0 (DIV BY ZERO), C should be equal to -9999.
l've set the datatype for A & B are INT, C is FLOAT at targetting database.
So l used to derived column to calculate C as,
B == 0 ? -9999 : 100 * A/B
After l run the package, l realize that all my C is INTEGER rather than FLOAT.....it seems that SQL server has evaluate the wrong datatype for me....anyway to overcome this?
I have a data flow task where I have mutiple columns (of different data types) , I want to create a single column using all these columns in XML format and load it into a table with a column of datatype XML. Can I accomplish this using Derived column tranformation?
"Failed insert into PONL_WELL. WELL_NO=" + (DT_WSTR,10)PROP_NO
PROP_NO comes from ms sql server , and the derived component datatype for this column is DT_WSTR.
The destination will be ms sql server, and i have a data conversion after the derived component to cast from DT_WSTR to DT_STR.
However, the derived component failed everytime giving me
Error: 0xC0049064 at Load Ponl_Well, Derived Column [1342]: An error occurred while attempting to perform a type cast.
Anyone know how i can eliminate the data conversion component and just do my string and column concatenation in the derived column and have it output as DT_STR?
I have an SSRS report that's being built from a stored procedure given 2 variables. The error I'm receiving is
An error has occurred during report processing. (rsProcessingAborted) Cannot read the next data row for the dataset Sheet2. (rsErrorReadingNextDataRow) Conversion failed when converting the varchar value '.5' to data type int.
This doesn't make any sense. The variable in question is being stored as a varchar. I don't do any typecasting in the stored procedure. Executing the stored proc in sql server studio works fine. In the query designer I replaced the stored procedure call with just the code for the stored procedure and it works fine as well. Switching it back to call the stored procedure throws the same error.
Our prod server is using 2008, our dev is running 2010, and I have 2013 Visual Studio. It has to do with the version of SSRS. I checked the datatype of the fieldtype and rd:TypeName was System.Int32. Changing it to System.String did nothing. Leaning even more towards the issue being SSRS itself. I even pulled the working version off of prod and it gave me the same error in Visual Studio.
Why is SSRS trying to convert a varchar to an int? It should be a double if anything or just leave it alone and not try typecasting it at all.
how to declare multiple derived columns in SSIS Derived Column Task in one attempt.as i have around 150 columns coming from Flat file. I had created the required Expression in Excel and now i want add those in derived column task but its allowing only 1 expression at a time.
In SQL Server for a field of datatype float(8), if i insert a value 2.62 , it saves it as 2.6200000000000001 like so for other values also. But in frontend i can see the right values.
I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A B C D E F G H
If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST SELECT '2014-09-30','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' UNION SELECT '2014-09-29','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' UNION SELECT '2014-09-28','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' GO INSERT INTO ##TEMP_TEST SELECT NULL,NULL,NULL,NULLÂ
Cannot see where I am going wrong. I always get a value of 0. I know my function works correctly, so it must be the VB.
CREATE FUNCTION [dbo].[getNextProjectID] () RETURNS varchar(10) AS BEGIN '''''''''''''''''''........................... DECLARE @vNextProjectID varchar(10) RETURN @vNextProjectID END
Sub LoadNextProjectNumber() Dim vProjectID As String Dim cmd As New SqlClient.SqlCommand() cmd.Connection = sqlConn cmd.CommandText = "getNextProjectID"
Hi, I have dates in "mmddyy" format coming from the sources and they are older dates of mid 80s like 082580 for instance.
When I cast it this way (DT_DBTIMESTAMP) Source_Date , It says ok but throws a runtime error.
When I hardcode a date in same format, (DT_DBTIMESTAMP) "082580" , It becomes red (an indication of syntax error) . Please note that we use double quotes in expressions in Derived Column Transformation; So an anticipation that using double quotes over single ones would be the syntax problem would be wrong.
Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
' Copy each source column to the destination column Function Main() DTSDestination("CM") = Month(Now) DTSDestination("CY") = Year(Now) DTSDestination("Comments") = DTSSource("Col031") DTSDestination("Manufacturer") = DTSSource("Col030") DTSDestination("Model") = DTSSource("Col029") DTSDestination("Last Check-in Date") = DTSSource("Col028") Main = DTSTransformStat_OK End Function *********************************************************** Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
I want to have an other employee table named employee_modified
Empno empname salary commission derived_column1(salary+commission) derived_column2(derived_column1 + xxxx) and so on derive other columns based on the earlier derived columns)
Is that possible to do it.. or am I doing something wrong.
Hi, how are you? I'm having a problem and I don't know if it can be solved with a derived column expression. This is the problem:
We are looking data in a a sql database.
We are writting the SQL result in a flat file.
We need to transform data in one of the columns.
For example: we can have 3 digits as value in a column but that column must be 10 digit length. So we have to complete all the missing digits with a zero. So, that column will have the original 3 digits and 7 zeros. How we can do that tranformation? We must do it from de the flat file or it can be a previous step? Thanks for any help you can give me. Regards,
I would like to INSERT an array of integer into a table in MSSQL Server, then count the number of rows in the table with c++ using ODBC. Here you find my code to do this task:
In my code, I would like to Insert the array and then count the number of rows:
SQLTCHAR Statement[] = _T("INSERT INTO information1(Wert1,Wert2) VALUES(?,?) select count(*) as a from information1 ") ;
Problem : My expectation is, that first 9 rows are inserted into table then comes 9 as result to user (if the table is empty) but this code returns me 1 if first the table is empty. If the table is not empty, it returns 1+number of  existing rows in the table. If I take a look inside the table, the 9 rows are successfully inserted in it. Only the number of rows in the table is wrong.
Hint : If I monitor the database using SQL Profiler. It looks like this:
SELECT * FROM ( SELECT TOP 15 * FROM (SELECT TOP 15 CMDS.STOCKCODE AS CODE,CMDS.STOCKNAME AS NAME,CMDS.Sector AS SEC, CMD7.REFERENCE AS REF,T1.HIGHP AS HIGH, T1.LOW,T1.B1_CUM AS 'B/QTY', T1.B1_PRICE AS BUY,T1.S1_PRICE AS SELL, T1.S1_CUM AS 'S/QTY', T1.D_PRICE AS LAST,T1.L_CUM AS LVOL,T1.Chg AS CHG,T1.Chgp AS CHGP, T1.D_CUM AS VOLUME,substring(T1.ST,7,6) AS TIME, CMDS.SERIAL as SERIAL FROM CMD7,CMDS,CMD4 AS T1 WHERE T1.ST IN (SELECT max(T2.ST) FROM CMD4 AS T2 ,CMDS WHERE T1.SERIAL=T2.SERIAL AND CMDS.SERIAL=T2.SERIAL AND T2.sd='20060821' AND CMDS.sd='20060821' AND T2.L_CUM < '1900' AND CMDS.sector >='1' AND CMDS.sector <='47') AND CMDS.SERIAL=T1.SERIAL AND CMDS.SERIAL=CMD7.SERIAL AND CMDS.sd='20060821' AND CMD7.sd='20060821' AND T1.sd='20060821' AND T1.L_CUM < '1900' AND CMDS.sector >='1' AND CMDS.sector <='47' ORDER BY T1.D_CUM desc) AS TBL1 ORDER BY VOLUME asc) AS TBL1 ORDER BY VOLUME desc;
Hi, wondering if anyone can help me. I currently have a field that has a date and time in it in the format dd/mm/yyyy hh:mm:ss. Ideally I would like to get rid of the time part of it altogether but for it to still be recognised as a date as opposed to a string. However, I've been told that this is not possible in 2005, is this true? If this is the case, what would be the best way to set the time to 00:00:00 after the date for all records on that field?
I am trying to transfer data from SQL Server 2005 table to another SQL Table. In the source table there is a field called Region [nvarchar(max)]. The values for these fields will be like APAC-China, NA-Racine, etc., i.e Region followed by the country name seperated by - symbol. I want the destination tablre with 2 fields Region[nvarchar(max)] and Country [nvarchar(max)]. I am using a Derived Column task to achieve the same.
Can anyone please help me out in doing this data conversion?
I am doing a task which will get all data based on several base and crosswork tables. I used stored procedure to get the data, but the next step will be using derived column to massaging data, and to load to the destination database. Is there a way to do that since I must generate data on the fly?
I am trying to create a derived column from two separate fields. One is a date field in format of 2008-03-01 and one is a time field. In DTS I use to have something like this:
I am trying to figure out how to do this in SSIS. I know I have to use a dervived column but can't seem to come up with the correct syntax. Any help would be apprecaited. thanks.
In a Derived Column data flow transformation, why can't I refer to a derived column (added in that same transformation) in the expression for another derived column? It seems I am forced to chain 2 DC data flows, just to do something as conceptually simple as:
a = x + y; b = a²
On a related note: Can I define a variable that is scoped to each row? Can I bind a variable in an expression to avoid creating a new row, e.g.
I have a quizzing application where users log in, answer questions, and are ranked relative to each other. For this final ranking, I calculate their score using this formula -
SELECT TOP 50 username, (sum(correct) * 150 / count(1) + count(1)) AS score, count(1) as totalq FROM questionsstats GROUP BY username ORDER BY score DESC
This works just fine.
However, on top of this I need to put an additional restriction that only users who have at least answered 20 questions be counted in. How can I do this? Adding a simple 'WHERE totalq > 20' does not work. I get the error "Invalid column name 'totalq'.".
1. In a if else expression if condition is false how do you keep the value of the source column eg: Name == "" ? "Unknown" : Name Above will change all the non blank values to Name and not the actual value in the Name Column eg. John
2. I have a column (unicode string)that stores date and time (The source is flat file) Is it possible to write expression to select the 1st day of month based on that date, and use this derived column as input to a table with a datetime field.
Hello, first time here, first time messing with SQL.
When creating a table in SQLServer2005 can you specify a column to be for a derived attribute. example a column monthlysalary and create a column that is a derived attribute - yearly salary. Is this done when creating the table and how is the syntax ?
but while transfering record from text file to table i need some logic here
my text file is "ID"|"Name" 1012|"10AA" 1013|"10BB"
logic is 10 should be replace by variable VID = 98
I defined this veriable as int
My ID column in database is int and Name column is varchar(50)
I try here expression like ID != 98 ? @[User::VID] : ID it work fine
but for varchar column I am not able to do I got error when i write expression SUBSTRING(Name,1,2) != "98" ? [DT_STR, 50, 1252] "(@[User::VID])" + rest of value of column : [Name]
my final output in table should be like ID..Name 98..98AA 98..98BB
I would like to validate datatype using Derived Column.My data type are such as numeric(X,X),datetime,int, and varchar.How do I do this using Derived Column.Example if row does not qualify as ISNUMERIC()...throw it in ERROR table else send it to SUCCESS table.Any Idea ?
Hi,I have a view that looks something like this -CREATE VIEW myview AS SELECTmyudf(col1) as col1, col2, col3FROM mytableThe view has an 'INSTEAD OF' trigger on it to do the correct thing oninsert. When I run the bcp, it runs successfully, but the valueinserted into col1 is always NULL. I modified my trigger to get abetter idea of what was happening, and when I look at the values ofINSERTED.col1, they are all null. It appears that bcp is setting thecolumn value to null, presumable because the view definintion for thiscolumn is a derived column.Does any one know a way around this?Thanks!
