Integration Services :: Converting Datatype In SSIS
Jun 19, 2015
I'm editing an SSIS package. The source column has datatype float and the data is stored like 1,2 instead of 1.2. To change this into a period instead of comma there is a derived column step in the ssis package. The expression in this derived column step to change this goes as:<o:p></o:p> (DT_STR ,32,1 252)(REPLACE((DT_STR,32,1252)SUBSCHAAL_SCORE,",","."))<o:p></o:p>
where SUBSCHAAL_SCORE is the name of the column. As you see the data is converted into a string. I need it to be converted into a numeric datatype (18,6) instead of string/varchar but it must also handle the first issue with changing the comma into a period. <o:p></o:p>

Using excel connection to load data to SQL Server When I try doing this character data is loading as nulls, I have tried by putting IMEX=1 property in connection string and removing IMEX=1 property from connection string , in both cases it is showing nulls, in the data viewer which i have placed after Excel source. I have also tried using the OPENROWSET which for some reason does not create an adhoc connection. I also tried changing the Datatypes in the advanced editor which again throws error. For some reason SSIS excel connection reads only the first 8 rows and decides a datatype and rest showup NULL.

I'm trying to convert a column in my source table of datatype varchar(6) to a column of datatype int in my destination. I tried using the Derived Column/Data Conversion transformations but none of them worked. So, I tried using the following C# (credits to the original poster) and getting an error during compilation.
Note: "MyCol" is the Input Column I've specified in the Script Component and "CleanCol" is the Output column I've specified as datatype [DT_I4].
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
int colOut = 0;
if (!Int32.TryParse(Row.MyCol, out colOut))
{
Row.CleanCol_IsNull = true;
} else {
Row.CleanCol = colOut;
}
}
The best overloaded method match for 'int.TryParse(string, out int)' has some invalid arguments
The other expression I've tried was:
ISNULL(MyCol) ? (dt_i4)"" : (dt_i4)MyCol
From the above code, you might have understood that the source field has some blank records as well in the MyCol field.
What is the best possible way to do the conversion from a String to Int or fixing the error from the above.

I am using OLE DB source to extract data from Oracle. I have query (sample) like below, but SSIS is converting ID as Unicode String [DT_WSTR]. Why is that? and how to avoid this?
SELECT
1 AS ID

I have a SSIS package which is reading from an Excel file.
The Excel is created from a report from another system and sometimes the date of birth formats as a Date and sometimes as string.
I've added a data viewer so I can see how the columns are read as soon as SSIS reads the file.
When the cell in Excel is set as text its read correctly - I can then convert to a date as necessary
When the cell in Excel is set as date its read in US format! i.e. if it was 01/13/2014 in excel its read as 13/01/2014
How can I get round this? Its not an option to manually force the column to be text once exported from the system as my package picks this up automatically.
I have tried
-Regedit set typeguessrows = 0
-IMEX = 1 in connection string
-Set LocaleID = UK in the data flow task to read from Excel

I have a csv file and I would like to load this file by SSIS in SQL Server.
One column of this file contains xml infos (it is about 60000 charachter), and I would like to have an xml column in Table in SQL Server.
From here the only ssis types, which able to contain so much character are DT_NTEXT and DT_TEXT.
If I want to have xml type in the target table in sql server, these both DT_NTEXT and DT_TEXT should be converted to DT_WSTR.
The Problem is: DT_WSTR can only contains 4000 charcters. In my situation with this infos, I can't have an xml column in target table in sql server.

I'm writing a custom source component that reads data from a SharePoint list with dynamic mapping to output columns. It's my first custom component and it's based on several samples and tutorials from Internet
Output columns are not created by the component itself, they must be added by user at design time. The component makes dynamically an association between SharePoint fields and available output columns at run-time (based on an mapping table).
I made a very basic skeleton and I encounter a problem when I add a column to output: it has no datatype and when I try to set one I have an the error Property value is not valid, The component xxxxxx does not allow setting output column datatype properties.

I am using rowVersion to detect rows that need to be re-extracted for my ETL. The first step in the ETL is to get MIN_ACTIVE_ROWVERSION() from the database, as well as the rowVersion from the last successful ETL run. Both of these values are saved in variables in SSIS. Since SSIS doesn't have an associated data type, these values are converted to nvarchar(512) before getting sent to SSIS.
I'm now trying to create a stored procedure to grab the data out of the source system. The sproc takes RowVersionMin and RowVersionMax as input parameters. Those parameters are then converted to varbinary(max), and I use them in a query to select the appropriate rows.
When I run the sproc in SSMS, it runs without a problem. However, when I try to use the sproc as a data source in SSIS, I get the following error: "Error converting data type nvarchar to varbinary". Why SSIS has a problem with this, but SSMS does not? The sproc code looks like this:
ALTER PROCEDURE [dbo].[dw_DimComment_DataLoad]
@RunType varchar(3),
@RowVersionMin nvarchar(512),
@RowVersionMax nvarchar(512)

I am reading a data source where all data in a given column is held as a string containing a percent value with 2 decimal points:
03.52%
12.32%
92.10%
80.05%
27.92%
100.00%
[...]
etc...
I need to convert these into decimal values with up to four decimal points, like this:
0.352
0.1232
0.9210
0.8005
0.2792
1.0000
I am trying to use the derived column editor but since I am fairly new to this, I am getting my wires crossed. c
1. Remove the % sign from the string -- not sure if I should use TRIM, or REPLACE
2. Divide the value by 100 -- but don't I need to do some sort of type casting first?
3. Do a cast to convert whatever I got into the correct decimals -- perhaps this isn't required if I did step 2 as a typecast to decimals already?

I have a stored proc that is being executed from an OLE DB Source component in my Data Flow. Takes one input parm, has several variables declared within, a derived table which is used in a join and all within a try catch block with transaction handling. No updates, just returning data, works great, except now I have been asked to replace these stored procs with inline queries.
ALTER PROCEDURE [dbo].[usp_Get_Test]
(
@numberOfMonthsint
)
AS
BEGIN
SET NOCOUNT ON
set transaction isolation level read uncommitted
[Code] ....
The problems I have run into so far are...
SQL command text in OLE DB Source Editor does not like:
- TRY/CATCH block
- Will not let me use my input parm (@numberOfMonths int)
- When I hard code in my input parm (select @BeginDate = dateadd(MONTH, -1, GETDATE())) I can parse query and run the step but no results are returned. So I am let to assume that it does not like the @TESTY derived table.
The query here as a sample has had pivots removed as well, but research suggests this should be an issue in the SQL command text.
Also, I know not even to try the Build Query... cause it will complain about any variable declarations (i.e., declare @BeginDate datetime).
For instance, can I pull this off with an Execute SQL Task? The problem is I don't see this available in the toolbox for the Data Flow.
Also, would my error handling be done in the Event Handlers tab now and if so, is there a good example of this?

I want to achieve the following in (SSIS/SSDT for SQL 2012) -
I have a generic SSIS package which simply sends out email notifications using SMTP email task (this package is within its own project, and has project level input parameters).
I need to be able to call this package in the Event handler section of every package (numbering in about less than 60) that we have. These packages are within their own respective projects.
I thought I could use the "execute package task", but it turns out , using this, I cannot call a package that is part of some other project. I also cannot call a package that is stored in the CATALOG. Is there any way I can do this ?
When I call the child package , I should be able to send in parameters like - error information and package name of the Parent package.

Can anyone help regarding the SQL server integration Services(SSIS), ETL
We have requirement like this:
We have Live Database( LIVE_DB ) and Reports Database (REP_DB)
I want to trasfer the few tables data from LIVE_DB into the REP_DB for end of the day using SSIS
If any new records are added, updated or deleted in LIVE_DB, these should reflect in the REP_DB, Our requirement is not to delete the old data, we should append or delete or insert the new transaction data in REP_DB.
Thanks in advance, if anyone help me in resolving this issue.
Regards,
Bhushanam.

Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,
B

Win 7 SP1 x64 PC. I installed SQL Server 2014 Dev Edition + Visual Studio 2015.
I'd like to create some basic ETL SSIS packages, and I worked very comfortably in 2008R2.
For 2014, I started with this tutorial:[URL]However, it says to go to Start->All Programs->Microsoft SQL Server->SQL Server Data Tools.
I did explicitly install SSDT when I installed VS2015. I also installed it separately. I see SSDT listed in Programs, and SSIS is running according to SQL Server Config Manager, and Services. Half of Microsoft's docs seem to be 2012 era, which is a shame because 2014 is out and it's nearly 2016...
how do I get to the GUI where I can design ETL packages?

We'll be using 2014 enterprise to populate some excel spreadsheets. We may not have the option of using ssrs so here is the question.
The excel spreadsheets have some pretty fancy heading structures, multiple tabs and in a few cases graphs that i'm sure are dependent on data sitting somewhere in the spreadsheet. The heading have variable info in them (eg FYxx where xx is a parameterized fiscal year, month names etc). Sometimes those headings have sub headings (with variable info) and so on.
Generally speaking how (if at all) do folks deal with this kind of excel challenge when limited to using ssis? I don't know if templates are going to be a good idea. I don't know if i'll be looking at a fair amount of c# etc code behind the scenes. I can be more specific depending on the feedback.
This is part of a conversion from 2 of the larger BI and statistical tools out there to the MS sql stack. Obviously with some shortcuts that we may wish we didn't take.

we have a table with xml column. This column has a large xml data . I am trying to use ssis to import xml from sql column (table a) to destination (another table).
steps which i did in ssis:
1. execute sql task:
fetch the xml column by query and store "full result set" into an object variable.
2. foreach loop:
select Ado enumerator option and select variable which has reset set of execute sql task. In variable mapping selected a new variable of type string.
when I run package I get below error:
"Error: ForEach Variable Mapping number 1 to variable "User::variable" cannot be applied".

Have Visual Studio 2008 R2 with SP 2 installed. Due to a merger we now have a MySQL database that we need to update from SSIS. Everything works except for the table insert or update. Would upgrading to SP 3 or SP 4 maybe useful with that?
We have installed the latest driver from MySQL. Have tried the ADO.Net and ODBC drivers with similar results when we try to update the database.

I have a ETL ( SSIS ) Process in which i am loading around 150 tables in each run. ( Truncate and Insert ). I have four packages each from different sources. ( Each package loads different tables and different numbers )These are run on weekly basis one after the other. Each package is taking around 60 to 90 minutes each. Now i want to track the progress of the ETL on my front End application.
We want this in two ways.
First Way : I need to show the user how much percent of ETL Process is completed
Second Way : I need to show the No of tables completed and how many rows have been completed in the ongoing table ( which is in process )
how to design the table and ssis process.

Im newto SSIS. I want to develop package for data validation.
FirstName
1. Mandatory field checking: if Null, reject the record
2. If field length > 50, then reject the record
SSN
1. If field length > 12, then reject the record
2. If SSN is not in valid format, issue warning and process rhe record without SSN value.
3. Valid format: 9 digit numeric values should present after striping off all non-numeric characters.
4. Only send 9 digits to MDM
Like these i have 30 rules. And I have to shop the error msg if the validation fails like "Mandatory feild is missing".
