More SQL Loader basics - using STR

Another random SQL Loader demo - here i'm assuming that the input file is just one long string of numbers separated by commas - i just want to load this into a single column table so i can do 'stuff' with it.

So i create a single column table

SQL> create table demo(col1 number);

Table created.

Here is my input file

# cat input.csv
1,2,3,4,5,66,77,888,99991,2,3,4,5,66,77,888,99991,2,3,4,5,66,77,888,99991,2,3,4,5,66,77,888,etc etc

And here is my controlfile

LOAD DATA
INFILE "input.csv" "STR ','"
INTO TABLE DEMO
TRUNCATE
FIELDS TERMINATED by ','
TRAILING NULLCOLS
(COL1)

The 'trick' is the use of the STR command to tell sqlloader that comma is my end or record marker (as well as being the end of field marker)

Now run that in

sqlldr demo/demo control=loader.ctl

And there we have it

      COL1

         1
         2
         3
         4
         5
        66
        77
       888
     99991
         2
   etc

Kind of pointless but the demo of the STR feature is useful
