SSIS datatype mismatch - ssis

I am trying to import from an oracle Source,I have a date field both on the source and destination.Its throwing error "there was an error with the input column on input OLE DB Destination failed with error code oxco209029A occured while processing input "OLE DB destination input(3554)".
I am trying to cahnge it to char in the Oracle query and change it to back to date..in the SSIS using data conversion, and it didnt work as well,may be I am doing something wrong,Could you guys have alook at this?I really appreciate it..Thanks guys

Oracle and SQL Server date types are a known incompatibility.

etc.
You've cast the Oracle type to some string equivalent and SQL Server isn't accepting the input for a (date, datetime, datetime2?) data type. Generally your options are to clean up your cast to be a recognizable date format or add a Derived Column Transformation to change the input string column to the SSIS equivalent. The exact type depends on what your target table has defined.

how to fix CONVERSION errors after importing SSIS PROJECT

I'm importing a perfectly working SSIS project from TFS.
I have actually a problem with all the packages that contain a data FLOW with a date importation.
I get dozens of this error :
Validation error. DFT Get Date ODBC Source CodeDate2 [63]: The OLE DB provider used by the OLE DB adapter cannot convert between types "DT_BYTES" and "DT_DBDATE" for "Date".
and when I click on the odbc source editor, I have the following message:
the metadata of the following output columnsdoes not match the metadata of the external columns with which the output columns are associated:
Output "ODBC Source Output": "Date"
Do you want to replace the metadata of the output columns with the metadata of the external columns?
the fact is that works everywhere but on my computer.
is there an ole db provider component I'm lacking of something like that?
Downgrading will work, but if that's not possible for you, then rewriting your queries may also solve your problem.
In my case I had a Postgres query returning columns of type date. I just converted them all to timestamptz using ::timestamptz. At that point the columns changed from DT_BYTES to DT_DBTIMESTAMP, which was just fine for my purposes.
It might be related to the version of Visual Studio or SSDT.
Try to install SSDT 15.8.0(SSDT previous releases), and run the package in it.
I once saw similar posts on MSDN after the release of Visual Studio 15.9.2
Import from Teradata using ODBC gives VS_NEEDSNEWMETADATA error
ODBC Progress datatype problems after updating to VS 2017 15.9
Same here, I forced the type casting it in the select and it works :
SELECT
[...]
cast(release_date as datetime) as release_date,
[...]
FROM cm_wo

SSIS Import a date and time from a txt to a table datetime

So I want to import a datetime from a txt:
2015-01-22 09:19:59
into a table using a data flow. I have my Flat Source File and my destination DB set up fine. I changed the data type for the txt input for that column in the advanced settings and the input and output properties to:
database timestamp [DT_DBTIMESTAMP]
This is the same data type as the DB used for the table so this should work.
However, when I execute the package I get a error saying the data conversion failed... How do I make this possible?
[Import txt data [1743]] Error: Data conversion failed. The data conversion for column "statdate" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
[Import txt data [1743]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "output column "statdate" (2098)" failed because error code 0xC0209084 occurred, and the error row disposition on "output column "statdate" (2098)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.
[Import txt data [1743]] Error: An error occurred while processing file "C:\Program Files\Microsoft SQL Server\MON_Datamart\Sourcefiles\tbl_L30T1.txt" on data row 14939.
On the row he is giving the error the datetime is filled up with spaces. that is why on the table the "allow nulls" is checked but my SSIS package gives the error for some reason... can I somewhere tell the package to allow nulls aswell?
I suggest you import the data in to a character field and then parse it after entry.
The following function should help you:
SELECT IsDate('2015-01-22 09:19:59')
, IsDate(Current_Timestamp)
, IsDate(' ')
, IsDate('')
The IsDate() function returns a 1 when it thinks the value is a date and a 0 when it is not.
This would allow you to do something like:
SELECT value_as_string
, CASE WHEN IsDate(value_as_string) = 1 THEN
Cast(date_as_string As datetime)
ELSE
NULL
END As value_as_datetime
FROM ...
I solved it Myself. Thank you for your suggestion gvee but the way I did it is way easier.
In the Flat File Source when making a new connection in the advanced tab I fixed all the data types according to the table in the database EXCEPT the column with the timestamp (in my case it was called "statdate")! I changed this data type to a STRING because otherwise my Flat File Source would give me a conversion error even before any scripts would have been able to be executed and the only way arround this was setting the error output to ignore failure wich I don't want. (You still have to change the data type after you set it to a string in the advanced settings by right clicking the flat file source -> show advanced editor -> going to the output colums and changing the data type there from Date to string.)
After the timestamp was set to a string I added a Derived Column with this expression to delete all the spaces and give it then "NULL" value:
TRIM(<YourColumnName>) == "" ? (DT_STR,4,1252)NULL(DT_STR,4,1252) : <YourColumnName>
Next I added a Data Conversion to set the string back to a timestamp. The Data conversion is finally connected to the OLE DB Destination.
I hope this helps anyone with the same problem in the future.
End result: Picture of data flow

Unparseable date error in Pentaho

I am using Pentaho to insert and update a table in Mysql.
Source database being oracle 11g and destination is Mysql database.
The query for getting max syncronization time from oracle is
SELECT
max(SYNC_TIME) AS LST
FROM Abc_ADM.ORA_SYNC_STATS
where SYNC_TIME is of Timestamp(6) datatype in Oracle in format 01-FEB-70 12.00.00.000000000 AM.
when i use this query and run the job i get error-
could not convert string [${LST}] to date using format [yyyy/MM/dd HH:MM:ss:SS] on offset location 0
unparseable date [${LST}]
What is that i am declaring wrong? please help
Pentaho is asking for a date-format like
yyyy/MM/dd HH:MM:ss:SS
But your Oracle-Output is different:
01-FEB-70 12.00.00.000000000 AM
For Pentaho its a string, no date at all.
It should work by telling Pentaho the Date-Format:
dd-MMM-yy HH.mm.ss
Do this in an input-Step
or by using a select-values ("Meta-data") step after your input
Important:
Type should be "Date" and Format: dd-MMM-yy HH.mm.ss
I can't post screenshots where you could have seen that it works for me.

Conversion error between "DT_DBTIME2" and "DT_WSTR" for "ETAHour"

I have a SQL query that returns me a "time(0)". I load that into SSIS, and it gets automatically converted to a "DT_DBTIME2", which is okay. I can transform it to any other type without error using a data conversion data flow item.
My problem is that when I try to insert that value into a "time(0)" field of a table, it gives me the following error:
The OLE DB provider used by the OLE DB adapter cannot convert between
types "DT_DBTIME2" and "DT_WSTR" for "ETAHour".
When I mouse over the fields in the OLE DB Destination component, it clearly says that the source field is a DT_DBTIME2 and the destination field is a DT_DBTIME2. I really wonder where this conversion error comes from.
Make sure that you are specifying provider in connection string.
In my case I'm using MSSQL 2012 Enterprise. It works on local machine, but after updating connection string in dtsconfig in installer it fails with error above.
Setting OLE DB provider fixed issue, in my case:
Provider=SQLNCLI11.1
Had a similar issue after importing an existing SSIS project created a new connection string and after I switched had multiple errors.
Changing the OLE DB provider to SQL Server Native Client 11.0 solved issue which is the equivalent of setting SQLNCLI11.1

SSIS (2008R2) import from mssql to mysql failing due to a date column

I have an oledb connection to mssql and an ado.net destination (with odbc driver used) to mysql. The tables are exectly the same and all the columns are working bar one.
The error message received is:
[ADO NET Destination [325]] Error: An exception has occurred during data insertion, the message returned from the provider is: Unable to cast object of type 'System.DateTime' to type 'System.Char[]'.
I've seen similar questions on other data types but the resolution of changing to string does not work here. If I convert to string (has to be length 29 otherwise the conversion step fails) I get the following error message:
[ADO NET Destination [325]] Error: An exception has occurred during data insertion, the message returned from the provider is: ERROR [HY000] [MySQL][ODBC 5.1 Driver][mysqld-5.5.15]Incorrect datetime value: '2011-03-21 11:23:48.573000000' for column 'LastModificationDate' at row 1
Other potentially relevant details:
connection driver- {MySQL ODBC 5.1 Driver}
script run before dataflow - set sql_mode='STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,ANSI_QUOTES'
Other datetime columns are working
This column has a reasonably high proportion of nulls
mssql spec: [LastModificationDate] [datetime] NULL
mysql spec: LastModificationDate datetime NULL
Has anyone had experience with this issue and could provide some advice on resolving it?
Can you try converting it to string on sql server side in your query using:
convert(char(10),LastModificationDate,111)+' '+convert(char(8),LastModificationDate,108)
This works for me all the time.
I got the same big headache this week. I tried many ways. Thanks God, finnally, one of them worked. Hope it could help you a little bit.
For some columns with the data type of Int, datetime, decimal....,here, I identified as ColumnA, and I used it as datetime type.
1.in Data Flow Source, use SQL Command to retrieve data. Sth like select isnull(ColumnA,'1800-01-01') as ColumnA, C1, C2, ... Cn from Table
Make sure to use Isnull function for all columns with the datatype mentioned before.
2.Excute the SSIS pkg. It should work.
3.Go back to Control Flow, under the data flow task, add SQL Task control to replace the data back. I mean, update the ColumnA from '1800-01-01' to null again.
That works for me. In my situation, I cannot use ignore failure option. Because if I do, I will lose thousands rows of data.
