I am trying to load JSON file from Staging area (S3) into Stage table using COPY INTO command.
create or replace TABLE stage_tableA ( RAW_JSON VARIANT NOT NULL );
copy into stage_tableA from @stgS3/filename_45.gz file_format = (format_name = 'file_json')
Got the below error when executing the above (sample provided)
SQL Error  [22P02]: Error parsing JSON: document is too large, max size 16777216 bytes 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.
When I had put "ON_ERROR=CONTINUE" , records got partially loaded, i.e until the record with more than max size. But no records after the Error record was loaded.
Was "ON_ERROR=CONTINUE" supposed to skip only the record that has max size and load records before and after it ?

String used to convert to and from SQL NULL. Snowflake replaces these strings in the data load source with SQL NULL.
Try setting the option strip_outer_array = true for file format and attempt the loading again.
The considerations for loading large size semi-structured data are documented in the below article:

I partially agree with Chris. The ON_ERROR=CONTINUE option only helps if the there are in fact more than 1 JSON objects in the file. If it's 1 massive object then you would simply not get an error or the record loaded when using ON_ERROR=CONTINUE.
If you know your JSON payload is smaller than 16mb then definitely try the strip_outer_array = true. Also, if your JSON has a lot of nulls ("NULL") as values use the STRIP_NULL_VALUES = TRUE as this will slim your payload as well. Hope that helps.

COPY INTO <table> — Snowflake Documentation, I'm attempting to copy data from an external stage into a Snowflake table, and doing a transformation mid-statement to extract all columns from a gzipped JSON file. but it seems odd that a copyOption with this exact purpose isn't working as intended. Here are the steps I used to reproduce your issue:. I've been able realign her on the center with some strafe running. Not sure if that is what to call it. I keep the the camera fixed and have her dash a little to one side or the other. Also noticed going into animations and such can fix it too. A bit annoying, but luckily pretty much the only issue I'm having.
Is it possible to continue on error when copying Parquet data into a , In this Topic: Loading JSON Data into a VARIANT Column an earlier load because the ON_ERROR copy option was set to CONTINUE during the load. @drewc.deprecated Hi, I wanted to reach out to see if you were able to resolve this. It has been a while since we heard from you and I was going to ask for some help in the stack overflow snowflake tag.
Is there a way to use both ON_ERROR=CONTINUE , Unfortunately my COPY INTO statements are failing on rows where FILE_FORMAT = (TYPE = PARQUET); ON_ERROR = CONTINUE; ENFORCE_LENGTH = FALSE;. Based on the suggestions for JSON data and a similar statement (https://docs.snowflake.net/manuals/sql-reference/sql/copy- into-table. If any one having problem while using SpringBoot here is how I fixed the issue without adding new dependency. In Spring 2.1.3 Jackson expects date string 2019-05-21T07:37:11.000 in this yyyy-MM-dd HH:mm:ss.SSS format to de-serialize in LocalDateTime.
- 1. 32361 records 2. 5351 got loaded 3. 5352 is error line
- Can you confirm that any of the lines after 5,321 do not have the same size limit being exceeded? You should attempt to reduce your document size before staging your file, 16MB seems large for a json document.
- Yes, lines after 5352 don't have the max size. I could load the entire file after removing the line 5352 and file got loaded successfully. And yes I understand that record size should be reduced, but it is coming from the source which we don't have control.
- I am not sure why the lines after 5352 wouldn't be loading. This is going to be a support ticket you'll need to log with Snowflake. Your understanding of the ON_ERROR parameter was correct. Sorry I could not be more help
- I see an indirect reference for ON_ERROR=CONTINUE here . docs.snowflake.net/manuals/sql-reference/sql/… Goto -> VALIDATION_MODE = RETURN_n_ROWS | RETURN_ERRORS | RETURN_ALL_ERRORS Then Check the notes for "RETURN_ALL_ERRORS" Returns all errors across all files specified in the COPY statement, including files with errors that were partially loaded during an earlier load because the ON_ERROR copy option was set to CONTINUE during the load. Looks like our understanding is incorrect.
