I'm trying to insert some value that is having Russian characters from SSIS.
Say I have a MYDATA.TXT (comma separated) and data as below
REM,DES,ID
FR1,Головка,8
GY2,6-гр,9
MO0,Болт,2
1st row is column headers. I'm using this in Flat file. After executing the task, the value are different in my table something like Головка
After some research I found that i have to use N before the text and column should be NVARCHAR. But i'm not sure how to do this in SSIS. I have around 1.2 million records, should I prefix my column with N for all rows or is there any other way in SSIS?
Try to change the code page to 65001 (UTF-8).
In Advanced tab change the Datatype of DES column to unicode string [DT_WSTR]
Output:

Every time that I try to import an Excel file into SQL Server I'm getting a particular error. When I try to edit the mappings the default value for all numerical fields is float. None of the fields in my table have decimals in them and they aren't a money data type. They're only 8 digit numbers. However, since I don't want my primary key stored as a float when it's an int, how can I fix this? It gives me a truncation error of some sort, I'll post a screen cap if needed. Is this a common problem?
It should be noted that I cannot import Excel 2007 files (I think I've found the remedy to this), but even when I try to import .xls files every value that contains numerals is automatically imported as a float and when I try to change it I get an error.

SSIS doesn't implicitly convert data types, so you need to do it explicitly. The Excel connection manager can only handle a few data types and it tries to make a best guess based on the first few rows of the file. This is fully documented in the SSIS documentation.
You have several options:
Change your destination data type to float
Load to a 'staging' table with data type float using the Import Wizard and then INSERT into the real destination table using CAST or CONVERT to convert the data
Create an SSIS package and use the Data Conversion transformation to convert the data
You might also want to note the comments in the Import Wizard documentation about data type mappings.
Going off of what Derloopkat said, which still can fail on conversion (no offense Derloopkat) because Excel is terrible at this:
Paste from excel into Notepad and save as normal (.txt file).
From within excel, open said .txt file.
Select next as it is obviously tab delimited.
Select "none" for text qualifier, then next again.
Select the first row, hold shift, select the last row, and select the text radial button. Click Finish
It will open, check it to make sure it's accurate and then save as an excel file.
There is a workaround.
Import excel sheet with numbers as float (default).
After importing, Goto Table-Design
Change DataType of the column from Float to Int or Bigint
Save Changes
Change DataType of the column from Bigint to any Text Type (Varchar, nvarchar, text, ntext etc)
Save Changes.
That's it.
When Excel finds mixed data types in same column it guesses what is the right format for the column (the majority of the values determines the type of the column) and dismisses all other values by inserting NULLs. But Excel does it far badly (e.g. if a column is considered text and Excel finds a number then decides that the number is a mistake and insert a NULL instead, or if some cells containing numbers are "text" formatted, one may get NULL values into an integer column of the database).
Solution:
Create a new excel sheet with the name of the columns in the first row
Format the columns as text
Paste the rows without format (use CVS format or copy/paste in Notepad to get only text)
Note that formatting the columns on an existing Excel sheet is not enough.
There seems to be a really easy solution when dealing with data type issues.
Basically, at the end of Excel connection string, add ;IMEX=1;"
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\YOURSERVER\shared\Client Projects\FOLDER\Data\FILE.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";
This will resolve data type issues such as columns where values are mixed with text and numbers.
To get to connection property, right click on Excel connection manager below control flow and hit properties. It'll be to the right under solution explorer. Hope that helps.
To avoid float type field in a simple way:
Open your excel sheet..
Insert blank row after header row and type (any text) in all cells.
Mouse Right-Click on the head of the columns that cause a float issue and select (Format Cells), then choose the category (Text) and press OK.
And then export the excel sheet to your SQL server.
This simple way worked with me.
A workaround to consider in a pinch:
save a copy of the excel file, modify the column to format type 'text'
copy the column values and paste to a text editor, save the file (call it tmp.txt).
modify the data in the text file to start and end with a character so that the SQL Server import mechanism will recognize as text. If you have a fancy editor, use included tools. I use awk in cygwin on my windows laptop. For example, I start end end the column value with a single quote, like "$ awk '{print "\x27"$1"\x27"}' ./tmp.txt > ./tmp2.txt"
copy and paste the data from tmp2.txt over top of the necessary column in the excel file, and save the excel file
run the sql server import for your modified excel file... be sure to double check the data type chosen by the importer is not numeric... if it is, repeat the above steps with a different set of characters
The data in the database will have the quotes once the import is done... you can update the data later on to remove the quotes, or use the "replace" function in your read query, such as "replace([dbo].[MyTable].[MyColumn], '''', '')"
I am trying to load data from an Excel .csv file to a flat file format to use as a datasource in a Data Services job data flow which then transfers the data to an SQL-Server (2012) database table.
I consistently lose 1 in 6 records.
I have tried various parameter values in the file format definition and settled on setting Adaptable file scheme to "Yes", file type "delimited", column delimeter "comma", row delimeter {windows new line}, Text delimeter ", language eng(English) and all else as defaults.
I have also set "write errors to file" to "yes" but it just creates an empty error file (I expected the 6,000 odd unloaded rows to be in here).
If we strip out three of the columns containing special characters (visible in XL) it loads a treat so I think these characters are the problem.
The thing is, we need the data in those columns and unfortunately, this .csv file is as good a data source as we are likely to get and it is always likely to contain special characters in these three columns so we need to be able to read it in if possible.
Should I try to specifically strip the columns in the Query source component of the dataflow? Am I missing a data-cleansing trick in the query or file format definition?
OK so didn't get the answer I was looking for but did get it to work by setting the "Row within Text String" parameter to "Row delimiter".
I usually have more code oriented questions, but I need help with a CSV database. Basically I need to change it's format to Fname;Lname;email. The problem is that I have 13000 rows and all of the data is in 1 column, the separator is ";". I used different CSV file editors and all of them put the data in 1 column, so I can't change the order of those columns... i cannot re-extract the data from the original database. So is there a fix to that, or am I screwed?
So I am starting with a CSV file, that has ";" between each data cell in each rows. So I open Excel 2016 and I do: data > from text > I find the CSV file > I click on delimited ";", start import on row 1, file origin: Windows (ANSI) > delimiter: ";" > column data format: "General" > finish. And I get all the data in 1 column...
If I understand you...
You could use excel and a vb macro to do the shuffling for you. Split by ';' and put each row in an array, shuffle, and then concatenate?
You can also change the column break when importing a csv in excel.
in the DataFlow-Task of an SSIS-Package I have a Flat-File-Source. The text in this file is encoded as UTF-8.
When I am using a lookup task to check a dimension table in the database, I get no match for text with special characters. The lookup task finds matches for many rows, but not for those with characters like "ü,ä,ö...". This is not corret, because there are rows in the table, so it should match.
What I've done so is, using a convert-task and convert the string from UTF-8 to Windows ANSI - Codepage 1252 with the exact same string length as the column in the Dimension table. The column in the dimension table has the collation "Latin1_General_CI_AS". I've also set the DefaulCodepage-Property of the lookup-task to 1252.
Does everyone know, what I did miss to do?
Thanks.
I have data in the csv file similar to this:
Name,Age,Location,Score
"Bob, B",34,Boston,0
"Mike, M",76,Miami,678
"Rachel, R",17,Richmond,"1,234"
While trying to BULK INSERT this data into a SQL Server table, I encountered two problems.
If I use FIELDTERMINATOR=',' then it splits the first (and sometimes the last) column
The last column is an integer column but it has quotes and comma thousand separator whenever the number is greater than 1000
Is there a way to import this data (using XML Format File or whatever) without manually parsing the csv file first?
I appreciate any help. Thanks.
You can parse the file with http://filehelpers.sourceforge.net/
And with that result, use the approach here: SQL Bulkcopy YYYYMMDD problem or straight into SqlBulkCopy
Use MySQL load data:
LOAD DATA LOCAL INFILE 'path-to-/filename.csv' INTO TABLE `sql_tablename`
CHARACTER SET 'utf8'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"'
IGNORE 1 LINES;
The part optionally enclosed by '\"', or escape character and quote, will keep the data in the first column together for the first field.
IGNORE 1 LINES will leave the field name row out.
UTF8 line is optional but good to use if names have diacritics, like in José.
