I am running my mapping on blaze engine and my target hive table is transnational.
I have a field coming from source with data type as 32000 (varchar), but when I run the mapping , it is getting failed with following error.
"The Integration Service failed to execute grid mapping with following error [An internal exception occurred with message: The length of the data is larger than the precision of the column.]."
Any insights will be very helpful
Note: 1. My target is a hive table and it's transactional properties are true.
2. I am running this mapping on blaze informatica engine which needs update strategy to be used.
3. Target column field length is also varchar(32000)
Check that the length of the source data you are ingesting is not bigger that 3200 characters.
If you using a flat file as source check the delimiters and be sure that is reading correctly the file.

I have a source component pulling data from an api and pushing it to an ADO.NET destination (from Kingswaysoft productivity pack). The ADO.NET destination is configured to redirect errors to a derived column and then to an error log SQL table, but fails to do so and instead errors out with this.
I don't understand why the redirect rows setting on the ADO.NET destination is not working.
The error that I receive is:
"KingswaySoft.IntegrationToolkit.ProductivityPack.DatabaseServiceException: The given value of type String from the data source cannot be converted to type nvarchar of the specified target column. (Detailed Message: The given value of type String from the data source cannot be converted to type nvarchar of the specified target column.)

I'm attempting to upload a CSV file (which is an output from a BCP command) to BigQuery using the gcloud CLI BQ Load command. I have already uploaded a custom schema file. (was having major issues with Autodetect).
One resource suggested this could be a datatype mismatch. However, the table from the SQL DB lists the column as a decimal, so in my schema file I have listed it as FLOAT since decimal is not a supported data type.
I couldn't find any documentation for what the error means and what I can do to resolve it.
What does this error mean? It means, in this context, a value is REQUIRED for a given column index and one was not found. (By the way, columns are usually 0 indexed, meaning a fault at column index 8 is most likely referring to column number 9)
This can be caused by myriad of different issues, of which I experienced two.
Incorrectly categorizing NULL columns as NOT NULL. After exporting the schema, in JSON, from SSMS, I needed to clean it
up for BQ and in doing so I assigned IS_NULLABLE:NO to
MODE:NULLABLE and IS_NULLABLE:YES to MODE:REQUIRED. These
values should've been reversed. This caused the error because there
were NULL columns where BQ expected a REQUIRED value.
Using the wrong delimiter The file I was outputting was not only comma-delimited but also tab-delimited. I was only able to validate this by using the Get Data tool in Excel and importing the data that way, after which I saw the error for tabs inside the cells.
After outputting with a pipe ( | ) delimiter, I was finally able to successfully load the file into BigQuery without any errors.
I'm using the new BQ Data Transfer UI and upon scheduling a Data Transfer, the transfer fails.
The error message in Run History isn't terribly helpful as the error message seems truncated.
Incompatible table partitioning specification. Expects partitioning specification interval(type:hour), but input partitioning specification is ; JobID: xxxxxxxxxxxx
Note the part of the error that says..."but input partition specification is..." with nothing before the semicolon. Seems this error is truncated.
Some details about the run:
The run imports data from a CSV file located in a GCS Bucket on a nightly basis. Once successfully ingested the process will delete the file. The target table in BQ is a partitioned table using the default partition pseudo column (_PARTITIONTIME)
What I have done so far:
Reran the scheduled Data Transfer -- which failed and threw the same error
Deleted the target table in BQ and recreated it with different partition specifications (day, hour, month) -- then Reran Scheduled Transfer -- failed and threw same error.
Imported the data manually (I downloaded the file from GCS and uploaded it locally from my machine) using the BQ UI (Create Table, append the specific table) - Worked perfectly.
Checked to see if this was a known issue here on Stack Overflow and only found this (which is now closed) -- close, but not exactly the issue. (BigQuery Data Transfer Service with BigQuery partitioned table)
What I'm holding off doing since it would take a bit more work.
Change schema of the target BQ table to include a specified column specific for partitioning
Include a system-generated timestamp in the original file inside of GCS and ensure the process recognizes this as the partitioning field.
Am I doing something wrong? Or is this a known issue?
Alright, I believe I have solved this. It looks like you need to include runtime parameters into your target table if the destination table is being partitioned.
https://cloud.google.com/bigquery-transfer/docs/gcs-transfer-parameters
Specifically this section called "Runtime Parameter Examples" here: https://cloud.google.com/bigquery-transfer/docs/gcs-transfer-parameters#loading_a_snapshot_of_all_data_into_an_ingestion-time_partitioned_table
They also advise that minutes cannot be specified in these parameters.
You will need to append the parameters to your destination table details as shown below:

previous have used varchar and never a problem, I have tried to convert data to Int and even increased the size but still getting this error. I have also tried using the Advance editor and changed data to almost anything I could think would cover datatype on that column, still getting an error. Thanks for the advice
Most likely you have "bad" records in your raw file.
For "bad", if could be one of these two: 1) implicitly conversion cannot be done to the string value; 2) string is too large (exceed 8000).
For debugging this, change the destination column to VARCHAR(MAX).
Then load the raw file (do not forget to increase the external column length to 8000 in the Advanced page in flag file connection manager).
if:
1) it is loaded successfully, query the table where ISNUMERIC([that numeric column]) =0, if anything returned, that is the bad record that cannot be converted when loading.
2) it is not loaded correctly, try to see if you have any value from that field has more than 8000 characters. (could use C# script if it is impossible to manually check)
So I'm trying to create and load Vora table from an ORC file created by SAP BW archiving process on HDFS.
The Hive table automatically generated on top of that file by BW has, among other things, this column:
archreqtsn decimal(23,0)
At attempt to create a Vora table using that datatype fails with the error "Unsupported type (DecimalType(23,0)}) on column archreqtsn".
So, the biggest decimal supported seems to be decimal(18,0)?
Next thing I tried was to either use decimal(18,0) or string as the type for that column. But when attempting to load data from a file:
APPEND TABLE F002_5_F
OPTIONS (
files "/sap/bw/hb3/nldata/o_1ebic_1ef002__5/act/archpartid=p20170611052758000009000/000000_0",
format "orc" )
I'm getting another error:
com.sap.spark.vora.client.VoraClientException: Could not load table F002_5_F: [Vora [<REDACTED>.com.au:30932.1639407]] sap.hanavora.jdbc.VoraException: HL(9): Runtime error. (decimal 128 unsupported (c++ exception)).
An unsuccessful attempt to load a table might lead to an inconsistent table state. Please drop the table and re-create it if necessary. with error code 0, status ERROR_STATUS
What could be the workarounds for this issue of unsupported decimal types? In fact, I might not need that column in the Vora table at all, but I can't get rid of it in the ORC file.
