I have a csv data file to upload to Snowflake. It has a column called Year-month with data like this: 2020-10, 2020-11, etc.
How could I upload the csv file to Snowflake? Which type of data does the Year-month column have?
Thanks

I am using Talend Studio with objects tFileInputDelimited row1(Main) to tOracleOutput what I want is to transfer the data in xml file to Oracle table.
I want to transfer the values of the last two columns (product_label and email_order) of my excel file to the product table which has this column structure (PRODUCT_ID,PRODUCT_CODE,PRODUCT_LABEL,EMAIL_COMAND
ORDER_ID).
Also, I want to process this condition if a row in my excel file contains an empty product code column then is not insert the column values product_label and email_command.
XML File to load
Product table
enter image description here
what is the proper settings in tFileInputDelimited , or do I need to use other tools?
Refer this image for your reference
Use tFileInputXMl file and filter the records by using tFilterRow and then connect with tOracleOutput
How do I write the contents of a deltalake table to a csv file in Azure databricks?
Is there a way where I do not have to first dump the contents to a dataframe? https://docs.databricks.com/delta/delta-batch.html
While loading the data to the Delta table, I used an ADLS Gen2 folder location for the creation of the versioned parquet files.
The conversion of parquet to CSV could then be accomplished using the Copy Data Activity in ADF.
You can simply use Insert Overwrite Directory.
The syntax would be
INSERT OVERWRITE DIRECTORY <directory_path> USING <file_format> <options> select * from table_name
Here you can specify the target directory path where to generate the file. The file could be parquet, csv, txt, json, etc.
Is it possible to make a loop in Hive to insert a bunch of random values in a table?
I understand that I can create a script in some programming language to create a csv file with the needed amount of rows and then load csv into hive as an external table.
So I want to have the table with 1000000 rows. The schema:
name String,
s_name String,
age int
Thanks in advance.
The proper way is to use csv (or any other file format) to insert data in Hive. If you don't want to use programming language you can use Excel (or any other analouge) to generate as may rows with random data as you need and then save them in CSV file. Hope this helps.
I want to extract data from Oracle database in csv or txt format. But because data table fields has CLOB datatype & text in it are more than 256 characters, it exported incomplete using usual extraction method.(Right click & save)
Is there any way to export data from Oracle as it is in csv or txt?
Based in the csv file column header it should create table dynamically and also insert records of that csv file into the newly create table.
Ex:
1) If i upload a file TEST.csv with 3 columns, it should create a table dynamically with three
2) Again if i upload a new file called TEST2.csv with 5 columns, it should create a table dynamically with five columns.
Every time it should create a table based on the uploaded csv file header..
how to achieve this in oracle APEX..
Thanks in Advance..
Without creating new tables you can treat the CSVs as tables using a TABLE function you can SELECT from. If you download the packages from the Alexandria Project you will find a function that will do just that inside CSV_UTIL_PKG (clob_to_csv is this function but you will find other goodies in here).
You would just upload the CSV and store in a CLOB column and then you can build reports on it using the CSV_UTIL_PKG code.
If you must create a new table for the upload you could still use this parser. Upload the file and then select just the first row (e.g. SELECT * FROM csv_util_pkg.clob_to_csv(your_clob) WHERE ROWNUM = 1). You could insert this row into an Apex Collection using APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY to make it easy to then iterate over each column.
You would need to determine the datatype for each column but could just use VARCHAR2 for everything.
But if you are just using generic columns you could just as easily just store one addition column as a name of this collection of records and store all of the uploads in the same table. Just build another table to store the column names.
Simply store this file as BLOB if structure is "dynamic".
You can use XML data type for this use case too but it won't be very different from BLOB column.
There is a SecureFile feature since 11g, It is a new BLOB implementation, it performs better than regular BLOB and it is good for unstructured or semi structured data.
