i am loading the data from csv file to snowflake staging table, but the records are not going to all the fields instead the data is going to single field.
i am using necessary options while creating file format.
type = csv
field_delimiter = ','
skip_header = 1
field_optionally_enclosed_by = '"'
please suggest if any option that i am missing here?
Thanks

I am using Azure data factory to copy data to Snowflake. Data file is in Parquet format. Some of the columns contain ''. This is causing an error during the copy execution.
Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=ERROR [22000] Found character 'W' instead of field delimiter ','
Data sample:
Col1 Col2
WO68239\ WO68239\
\ WO12345
I tried these snowflake copy options which did not work.
ESCAPE_UNENCLOSED_FIELD = NONE
ESCAPE = \
Any suggestions on how to fix this problem?
Thanks,
When trying to load a Parquet/AVRO file into a Snowflake table I get the error:
PARQUET file format can produce one and only one column of type variant or object or array. Use CSV file format if you want to load more than one column.
But I don't want to load these files into a new one column table — I need the COPY command to match the columns of the existing table.
What can I do to get schema auto detection?
Good news, that error message is outdated, as now Snowflake supports schema detection and COPY INTO multiple columns.
To reproduce the error:
create or replace table hits3 (
WatchID BIGINT,
JavaEnable SMALLINT,
Title TEXT
);
copy into hits3
from #temp.public.my_ext_stage/files/
file_format = (type = parquet);
-- PARQUET file format can produce one and only one column of type variant or object or array.
-- Use CSV file format if you want to load more than one column.
To fix the error and have Snowflake match the columns from the table and Parquet/AVRO files just add the option MATCH_BY_COLUMN_NAME=CASE_INSENSITIVE (or MATCH_BY_COLUMN_NAME=CASE_SENSITIVE):
copy into hits3
from #temp.public.my_ext_stage/files/
file_format = (type = parquet)
match_by_column_name = case_insensitive;

I have CSV file on Azure blob storage. It has 4 columns in it without headers and one blank row at starting. I am inserting CSV file into SQL managed instance by bulkinsert and I have 5 columns in the database table. I don't have 5th column in CSV file.
Therefore it is throwing this error:
Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 5 (uId2)
As I want to insert that 4 columns from CSV file to table in database and I want that 5th column in table as NULL.
I am using this code:
BULK INSERT testing
FROM 'test.csv'
WITH (DATA_SOURCE = 'BULKTEST',
FIELDTERMINATOR = ',',
FIRSTROW = 0,
CODEPAGE = '65001',
ROWTERMINATOR = '0x0a'
);
Want that 5th row as NULL in database table, if there are 4 columns in CSV file.
Sorry, we achieve that in bulk insert. None of other ways according my experience.
Azure SQL managed instance is also not supported as dataset in Data Factory Data flow. Otherwise we can using Data Flow derived column to create a new column to mapping to the Azure SQL database.
The best way is that you editor your csv file: just add new column as header in you csv files.
Hope this helps.
I'm trying to import data from a .csv file into a SQL Server table.
Using the code below, I can read from the file:
BULK INSERT #TempTable
FROM '\\Data\TestData\ImportList.csv'
WITH (FIELDTERMINATOR = ',', ROWTERMINATOR ='\n', FIRSTROW = 2, Lastrow = 3)
GO
(I added LastRow = 3 so I was just getting a subset of the data rather than dealing with all 2000 rows)
But I am getting multiple columns into a single column:
If I use the Import/Export wizard in SSMS, with the below settings, I see the expected results in the preview:
Can anyone give me some pointers as to how I need to update my query to perform correctly.
Here is a sample of what the CSV data looks like:
TIA.
You probably need to specify " as Text qualifier.
Your fields seem to be quoted and most likely contain comma's, which are currrently splitting your fields.
Or, if it works fine using <none> as Text qualifier, try to use FIELDQUOTE = '' or FIELDQUOTE = '\b' in your query. FIELDQUOTE defaults to '"'.
It's hard to tell what's really wrong without looking at some raw csv data that includes those quotes (as seen in your first screenshot).
I have a text file of coauthor data set containing author id's and number of co-authored papers separated by spaces. I want to import this data in sql server table whereas number of records in this text file is in millions i.e. of size 73MB of text file.
Please help out the way by which I can import this file to sql server table.
Thanks
BULK
INSERT yourtable
FROM 'location with filename'
WITH
(
FIELDTERMINATOR = ' ',
ROWTERMINATOR = '\n'
);

another GUI approach can be useful.
