we are facing below issue while loading csv file from S3 to Snowflake.
SQL Compilation error: Insert column value list does not match column list expecting 7 but got 6
we have tried removing the column from table and tried again but this time it is showing expecting 6 but got 5
below are the the commands that we have used for stage creation and copy command.
create or replace stage mystage
url='s3://test/test'
STORAGE_INTEGRATION = test_int
file_format = (type = csv FIELD_OPTIONALLY_ENCLOSED_BY='"' COMPRESSION=GZIP);
copy into mytable
from #mystage
MATCH_BY_COLUMN_NAME = CASE_INSENSITIVE;
FILE_FORMAT = (TYPE = CSV FIELD_OPTIONALLY_ENCLOSED_BY='"' COMPRESSION=GZIP error_on_column_count_mismatch=false TRIM_SPACE=TRUE NULL_IF=(''))
FORCE = TRUE
ON_ERROR = Continue
PURGE=TRUE;
You can not use MATCH_BY_COLUMN_NAME for the CSV files, this is why you get this error.
This copy option is supported for the following data formats:
JSON
Avro
ORC
Parquet

Again I am facing an issue with loading a file into snowflake.
My file format is:
TYPE = CSV
FIELD_DELIMITER = ','
FIELD_OPTIONALLY_ENCLOSED_BY = '\042'
NULL_IF = ''
ERROR_ON_COLUMN_COUNT_MISMATCH = FALSE
[ COMMENT = '<string_literal>' ]
Now by running the:
copy into trips from #citibike_trips
file_format=CSV;
I am receiving the following error:
Found character ':' instead of field delimiter ','
File 'citibike-trips-json/2013-06-01/data_01a304b5-0601-4bbe-0045-e8030021523e_005_7_2.json.gz', line 1, character 41
Row 1, column "TRIPS"["STARTTIME":2]
If you would like to continue loading when an error is encountered, use other values such as 'SKIP_FILE' or 'CONTINUE' for the ON_ERROR option. For more information on loading options, please run 'info loading_data' in a SQL client.
I am a little confused about the file I am trying to load. Actually, I got the file from a tutorial on YouTube and in the video, it works properly. However, inside the file, there are not only CSV datasets, but also JSON, and parquet. I think this could be the problem, but I am not sure to solve it, since the command code above is having the file_format = CSV.
Remove FIELD_OPTIONALLY_ENCLOSED_BY = '\042' , recreate the file format and run the copy statement again.
You're trying to import a JSON file using a CSV file format. In most cases all you need to do is specify JSON as the file type in the COPY INTO statement.
FILE_FORMAT = ( { FORMAT_NAME = '[<namespace>.]<file_format_name>' |
TYPE = { CSV | JSON | AVRO | ORC | PARQUET | XML } [ formatTypeOptions ] } ) ]
You're using CSV, but it should be JSON:
FILE_FORMAT = (TYPE = JSON)
If you're more comfortable using a named file format, use the builder to create a named file format that's of type JSON:
I found a thread in the Snowflake Community forum that explains what I think you might have been facing. There are now three different kinds of files in the stage - CSV, parquet, and JSON. The copy process given in the tutorial expects there to be only CSV. You can use this syntax to exclude non-CSV files from the copy:
copy into trips from #citibike_trips
on_error = skip_file
pattern = '.*\.csv\.gz$'
file_format = csv;
Using the PATTERN option with a regular expression you can filter only the csv files to be loaded.

And if you also run into an error related to timestamps, you will want to set this file format before you do the copy:
create or replace file format
citibike.public.csv
type = 'csv'
field_optionally_enclosed_by = '\042'
S3 to Snowflake ( loading csv data in S3 to Snowflake table throwing following error)
I am having trouble loading data from an amazon S3 bucket to the snowflake table. This is my command:
copy into myTableName
from 's3://dev-allocation-storage/data_feed/'
credentials=(aws_key_id='***********' aws_secret_key='**********')
PATTERN='.*/.*/.*/.*'
file_format = (type = csv field_delimiter = '|' skip_header = 1 error_on_column_count_mismatch=false );
I have 3 CSV files in my bucket and they are all being loaded into the table. But I have 8 columns in my target table, but they are all being loaded into the first columns as a JSON object.
Check that you do not have each row enclosed in double-quotes. Something like "f1|f2|...|f8". This will be treated like one single column value. Unlike "f1"|"f2"|...|"f8".
i am trying to unload Snowflake tale data into S3 bucket in parquet format. but getting below error.
`SQL compilation error: COPY statement only supports simple SELECT from stage statements for import.`
below is the syntax of copy statement
`create or replace stage STG_LOAD
url='s3://bucket/foler'
credentials=(aws_key_id='xxxx',aws_secret_key='xxxx')
file_format = (type = PARQUET);
copy into STG_LOAD from
(select OBJECT_CONSTRUCT(country_cd,source)
from table_1
file_format = (type='parquet')
header='true';`
please let me know if i am missing anything here.
You have to identify named stages using the # symbol. Also the header option is true rather than 'true'
copy into #STG_LOAD from
(select OBJECT_CONSTRUCT(country_cd,source)
from table_1 )
file_format = (type='parquet')
header=true;
I coudln't load the samefile into table in snowflake using COPY command/snowpipe.
I am always getting the following result
Copy executed with 0 files processed.
I have re-created the table. Truncated the table. But the copy_history doesn't show any data
select * from table(information_schema.copy_history(table_name=>'mytable', start_time=> dateadd(hours, -10, current_timestamp())));
I have used FORCE = true in COPY Command and COPY command didnt load the same file into Table. I have explicitly mentioned file path in COPY COMMAND
FROM
#STAGE_DEV/myfile/05/28/16/myfile_1.csv
) file_format = (
format_name = STANDARD_CSV_FORMAT Skip_header = 1 FIELD_OPTIONALLY_ENCLOSED_BY = '"' NULL_IF = 'NULL'
)
on_error = continue
Force = True;
Anyone faced similar issue and what would the process to load the same file again using COPY command or SNOWPIPE ? I dont have option to change file name or put the files in different S3 bucket.
ls#stage shows the following files ls#stage
I have reloaded files to S3 bucket and it's working. Thank you guys for all the responses. –
In a file, few of the rows have \ in a column value for example, i have rows in below format.
101,Path1,Z:\VMC\PSPS,abc
102,Path5,C:\wintm\PSPS,abc
I was wondering how to load \ character
COPY INTO TEST_TABLE from #database.schema.stage_name FILE_FORMAT = ( TYPE = CSV FIELD_OPTIONALLY_ENCLOSED_BY = '\"' SKIP_HEADER = 1 );
is there any thing that i can mention the file_format line?
Are you still getting this error? I just tried to recreate it by creating a CSV based off your sample data and a test table. I loaded the CSV into an internal stage and then ran your COPY command. It worked for me. Please see the screenshot below.
Could you provide more details on the error you are facing? Perhaps there was something off with your table definition.
