I have a row in my CSV file like mentioned below
"TEXT"|"123584543"||||"Sherly"||"E'Sheryl"|||"DOCT"||"DC"|||||"AC"|||||||||||
I am trying to create stage using the below query:
Create or Replace file format test_stg
type = CSV
RECORD_DELIMITER = '\n'
FIELD_DELIMITER = '|'
FIELD_OPTIONALLY_ENCLOSED_BY = '\042'
SKIP_HEADER=1
empty_field_as_null = true
ESCAPE = '"';
When I run the above query I'm getting error which I have mentioned below:
**SQL compilation error: value [\"] for parameter 'FIELD_OPTIONALLY_ENCLOSED_BY' conflict with parameter 'ESCAPE'**
When I try the below query, it is getting executed successfully.
create or replace file format test_stg1
type = csv
record_delimiter = '\n'
field_delimiter = '|'
skip_header = 1
null_if = ('NULL', 'null')
empty_field_as_null = true
FIELD_OPTIONALLY_ENCLOSED_BY = '0x22';
This query gets executed successfully. But when I run the COPY command, I'm getting an unusual error - Found character instead of field delimiter '|'.
Can anyone guide in fixing this issue?
Thanks :)
Remove the FIELD_OPTIONALLY_ENCLOSED_BY = '0x22' ,recreate file format and run the copy statement.

I created a file format:
create or replace file format po_req
type='csv'
compression='none'
FIELD_DELIMITER = ','
RECORD_DELIMITER = '\n'
TRIM_SPACE = FALSE
ESCAPE_UNENCLOSED_FIELD= '\\'
NULL_IF = ('NULL', 'null', '')
SKIP_BYTE_ORDER_MARK = False;
Then run a COPY INTO:
copy into "PACE_TEST"."STAGING"."INVOICE_DETAILS"
from #~/stages/mystage/file1.csv
file_format = po_req
on_error = 'ABORT_STATEMENT'
PURGE = TRUE;
Below is the error I am encountering :
End of record reached while expected to parse column
'"INVOICE_DETAILS"["Dist#":15]' File '#~/stages/mystage/file1.csv',
line 1176, character 231 Row 1176, column
"INVOICE_DETAILS"["Dist#":15] 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 tried changing the file format but still facing the same error. i removed all special characters .
I am trying to load a CSV file from S3. which has a null value in the integer type data field in the snowflake table.
So I try to use IFFNULL function but gets the error.
Numeric value 'null' is not recognized.
For example when I try
select IFNULL(null,0)
I get the answer as 0.
but the same thing when I try while reading the CSV file won't work
select $1,$2,ifnull($2,0)
from
#stage/path
(file_format => csv)
I get the null not recognized Error.
and it fails when $2 is null.
My csv format is as below.
create FILE FORMAT CSV
COMPRESSION = 'AUTO' FIELD_DELIMITER = ','
RECORD_DELIMITER = '\n' SKIP_HEADER = 0
FIELD_OPTIONALLY_ENCLOSED_BY = '\042'
TRIM_SPACE = FALSE
ERROR_ON_COLUMN_COUNT_MISMATCH = TRUE ESCAPE = '\134'
ESCAPE_UNENCLOSED_FIELD = '\134' DATE_FORMAT = 'AUTO'
TIMESTAMP_FORMAT = 'AUTO' NULL_IF = ('\\N');
Basically, I am just trying to convert null to 0, when reading from the stage.
The null string literal could be handled by setting NULL_IF:
CREATE FILE FORMAT CSV
...
NULL_IF = ('null', '\\N');
I used the second option listed in the Snowflake documentation specifying FIELD_OPTIONALLY_ENCLOSED_BY=NONE and EMPTY_FIELD_AS_NULL = FALSE in which case I'd need to provide a value to be used for NULLs (NULL_IF=('NULL')
https://docs.snowflake.com/en/user-guide/data-unload-considerations.html
"Leave string fields unenclosed by setting the FIELD_OPTIONALLY_ENCLOSED_BY option to NONE (default), and set the EMPTY_FIELD_AS_NULL value to FALSE to unload empty strings as empty fields.
If you choose this option, make sure to specify a replacement string for NULL data using the NULL_IF option, to distinguish NULL values from empty strings in the output file. If you later choose to load data from the output files, you will specify the same NULL_IF value to identify the NULL values in the data files."
So my query looked something like the following:
COPY INTO #~/unload/table FROM (
SELECT * FROM table
)
FILE_FORMAT = (TYPE = 'CSV' COMPRESSION = 'GZIP'
FIELD_DELIMITER = '\u0001'
EMPTY_FIELD_AS_NULL = FALSE
FIELD_OPTIONALLY_ENCLOSED_BY = NONE
NULL_IF=('NULL'))
OVERWRITE = TRUE;
Problem Statement -
While doing the data load using the copy command and by defining the escape property the statement is not eliminating the escape character from the data.
Ex-
I'm trying to load the data from the CSV file. The file is having the data in the following Format in one of the column ('EC F&G BREWER\'S INT\'L BEER'). The expectation on this is that the escape character in the data (which is backslash '\') should be removed from the data field after the load.
Following is the copy statement I'm using -
COPY INTO SANDBOX.TEST_SBX.TEST_20200512
FROM #STAGE_NAME/TEST_FILE/
FILE_FORMAT = (FIELD_DELIMITER = ','
RECORD_DELIMITER = '\n'
SKIP_HEADER = 0
FIELD_OPTIONALLY_ENCLOSED_BY = '\047'
TRIM_SPACE = FALSE
ESCAPE ='\134'
ESCAPE_UNENCLOSED_FIELD='\134'
ERROR_ON_COLUMN_COUNT_MISMATCH = FALSE
DATE_FORMAT = 'AUTO' TIMESTAMP_FORMAT = 'AUTO' NULL_IF = ('NULL', 'null', '') )
PATTERN='.*.gz.*'
PURGE=FALSE
ON_ERROR = ABORT_STATEMENT
FORCE = FALSE
RETURN_FAILED_ONLY = FALSE
;
There are many columns in this file that have the () backslash in the character field, and all are getting ignored during the load.
I cannot switch to the manual column selection mode and use the Regexp to replace the escape character, I have to use the copy command without switching to the column selection mode.
I expected that the escape character configured in the file format is treated appropriately (escaped) without having to treat it as a transformation similar to how it is treated as escape characters in the other data processing/loading engines.
Please suggest what I can do here on this.
This is the code I have implemented
--Data File
'EC F&G ANSHUL\'s Public COMPANY'
'YB MARTHA\'S VINEYARD LOUNGE'
'EC F&G BREWER\'S INT\'L BEER'
COPY INTO test_so FROM #file_format_stage/Test_File.csv.gz
FILE_FORMAT = (FIELD_DELIMITER = ',' RECORD_DELIMITER = '\n'
SKIP_HEADER = 1 FIELD_OPTIONALLY_ENCLOSED_BY = '\047'
TRIM_SPACE = FALSE
ESCAPE ='\\'
--ESCAPE_UNENCLOSED_FIELD=NONE
NULL_IF = ('NULL', 'null', '')
SKIP_BYTE_ORDER_MARK = False)
force=true
;
And the result
I tried replicating exactly the same still not getting the same result. Got the understanding there is problem with the file . Or something wrong at the account level parameters which is cause the problem.
CREATE OR REPLACE TABLE SANDBOX.AAGRA018_SBX.TEXT_FILE_TST
(COL1 VARCHAR(50)
);
TRUNCATE TABLE SANDBOX.AAGRA018_SBX.TEXT_FILE_TST;
COPY INTO SANDBOX.AAGRA018_SBX.TEXT_FILE_TST
FROM #~/Test_File.txt.gz
FILE_FORMAT = (FIELD_DELIMITER = ',' RECORD_DELIMITER = '\n'
SKIP_HEADER = 0 FIELD_OPTIONALLY_ENCLOSED_BY = '\047'
TRIM_SPACE = FALSE ESCAPE ='\\' --ESCAPE_UNENCLOSED_FIELD='\134'
NULL_IF = ('NULL', 'null', '')
)
force=true;
select * from SANDBOX.AAGRA018_SBX.TEXT_FILE_TST;
Data File -
YB MARTHA\'S VINEYARD LOUNGE
EC F&G BREWER\'S INT\'L BEER
This is not giving the desired result

I staged a csv file has all the fields enclosed in double quotes (" ") and comma separated and rows are separated by newline character. The value in the enclosed fields also contains newline characters (\n).
I am using the default FILE FORMAT = CSV. When using COPY INTO I am seeing a column mismatch error in this case.
I solved this first error by adding the file type to specify the FIELD_OPTIONALLY_ENCLOSED_BY = attribute in the SQL below.
However when I try to import NUMBER values from csv file, I already used FIELD_OPTIONALLY_ENCLOSED_BY='"'; but it's not working. I get "Numeric value '"3922000"' is not recognized" error.
A sample of my .csv file looks like this:
"3922000","14733370","57256","2","3","2","2","2019-05-23
14:14:44",",00000000",",00000000",",00000000",",00000000","1000,00000000","1000,00000000","1317,50400000","1166,50000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000",",00000000","","tcllVeEFPD"
My COPY INTO statement is below:
COPY INTO '..'
FROM '...'
FILE_FORMAT = (TYPE = CSV
STRIP_NULL_VALUES = TRUE
FIELD_DELIMITER = ','
SKIP_HEADER = 1
error_on_column_count_mismatch=false
FIELD_OPTIONALLY_ENCLOSED_BY = '"'
)
ON_ERROR = "ABORT_STATEMENT";
I get a feeling that NUMBER is interpreted as STRING.
Does anyone have solution for that one?
Try using a subquery in the FROM clause of the COPY command where each column is listed out and cast the appropriate columns.
Ex.
COPY INTO '...'
FROM (
SELECT $1::INTEGER
$2::FLOAT
...
)
FILE_FORMAT = (TYPE = CSV
STRIP_NULL_VALUES = TRUE
FIELD_DELIMITER = ','
SKIP_HEADER = 1
error_on_column_count_mismatch=false
FIELD_OPTIONALLY_ENCLOSED_BY = '"'
)
ON_ERROR = "ABORT_STATEMENT";
I am loading data from file in S3 using copy into command and have following parameters:
file_format = (
type = 'csv'
field_delimiter = '~'
FIELD_OPTIONALLY_ENCLOSED_BY= '"'
EMPTY_FIELD_AS_NULL = TRUE
NULL_IF=""
ESCAPE_UNENCLOSED_FIELD = None)
My load is breaking every time I have double-quote inside a field. I tried to replace it by escape \" and adding escape = '\' to the file format parameters, but nothing seems to work.
Can someone offer a solution?
Thank you,
Create or replace file format name
file_format = (type = 'csv')
field_delimiter = '~'
FIELD_OPTIONALLY_ENCLOSED_BY= '"'
EMPTY_FIELD_AS_NULL = TRUE
NULL_IF=""
ESCAPE_UNENCLOSED_FIELD = '\\'
Can you please share a data sample? Is the staged file on S3 compressed?
COMPRESSION = AUTO
