I've got around 500 csv files, I've merged them into one big csv file - ~10gb and 10mln rows. I've got a local database, I'm importing data through sql developer, after successful import rows available are only ~3.8mln.
Has anyone got an idea why I've got this loss of data? I've checked all csv, everything is ok with them.
I made a job design which consists of tFileInputDelimited -> tMap -> tDBOutput(Oracle)
The csv I am using has columns which are not currently in the table which I don't think should be a problem.. but when I run my job I get multiple ORA-00904 invalid identifier errors.
I check my DB in Oracle SQL developer and no rows have been updated.
Looking for some help how to fix this.. I looked up the error and I get referenced to a SQL code but I am not using SQL only a CSV file to upload.
Thank you!
You say that your csv has columns that are not in your table. That is a problem if you map those columns to the tMap output. Only those columns which are present in your target table need to be in the tMap output flow going to tDBOutput.
I am trying to import 3 million rows from a csv file to DB table using sql developer import wizard, but getting below error every time when it reaches 12k rows .
When I tried importing only 100 rows from the same file, it inserted successfully. Please help me with the error.

After successfully importing data from excel into sql developer when I type:
select * from table_name
it says no rows selected whereas excel file has huge data (around 1000 records). Please help
I have never worked with Oracle. This is the first time and the job is quite tricky. I have a text file with records delimited with tab. These records are to be imported into a database using pl-sql. I have searched online but the solutions suggests using SQL Loader utility. But the requirement is to do that using sql statements. No command line utility. Preferable the SP or UDF will take file path and database name as input parameters and it will import the records when executed. Is this possible? Can someone provide me sample sql statements or any link that explain this process step by step? Also note that there can be blank records in file. Thanks in advance.
External Tables seems like the best approach.

UTL_FILE is possible but you would have to write the code to parse the tab delimited text etc.
