Any limitation number of columns on SQL Workshop Utility Upload Data ?

Question

Hi there
I tried to load csv fiie into a table with 350 columns and received the following error.
++ORA-20001: Load csv data error: ORA-01461: can bind a LONG value only for insert into a LONG column++
++Error inserting data.++
++Return to application.++
if the column in csv file is reduced to 310, it will insert the data.
Are there any limitations on number of column on this functionality ?
In my application I also tried to create data loading wizard into the table with 350 columns.
When I tried to load data through my application, the data mapping did not pick up all columns from the csv file, yet it manage to insert data and loading information for the first 46 columns.
Are there any limitations on number of column on this functionality as well ?
Thanks
Dian

Answer 1

Then I would look at this stage as a step to develop a way to NORMALIZED the data when it comes into the application. Instead of just importing and the trashing around with it, your SOURCE IS THE EXCEL workbook. After that point you start by importing in with SQL Loader or something other which then does the parsing into the required work tables. Building a work table with 350 columns JUST to cut up the data is just adding a layer to the puzzle.. At least this is how I would accomplish the task.
At NO point would I try building a user interface on the work table(s) since the data is just not in a viewable format at that point, only after the data is normalized would users be seeing it for review, then they could start to atleast verify the accuracy..
