Server Utilities :: How To Create External Table
Aug 10, 2012
im trying to create an external table, and i load my data without no problem, and everything is fine, but i got some behavior with one column that i would like to know whats behind scenes, OK let's get the example:
[*] Sample Data
Line 1:333 1111111112009100000000000080000000013450.33
Line 2:11111111111220091016000000004.48
Line 3:222222222 220091016000000004.48
Line 4:(This is a blank line left)
And this is my External Table Create Query:
CREATE TABLE EXT_TABLE_TEMP
(COL_A VARCHAR2(11),
COL_B VARCHAR2(1),
COL_C DATE,
COL_D NUMBER(12,2))
ORGANIZATION EXTERNAL
[code]....
As you can see i can upload my table with no problem but i always get 3 lines counting last blank line if i try LOAD WHEN COL_A != BLANKS, i dont know if its a problem of the blank space left between fixed fields length, but if i do LOAD WHEN COL_B != BLANKS i get correct result 2 lines instead of 3, i want to know why (missing fields...) and (reject rows...) are not working...
Note: COL_A could be 9-11 length, if length its 9 then 2 spaces left before next one...

Can I create an external table for loading this file based on selection of fields driven by the record identifier which is the first field of each record, except for the firt two?
For e.g In the above file, for records which say 'abc' in it's first field, I want to load the 2,3,6,8 fields delimited by a comma (the values may as well be null in those fields) and for records which say 'Product' in their first fields, I want to load 5,8,9 and 10 fields from the same file. Basically, I want to know if we can use instr function while choosing the fields line by line based on a search criteria in the file. There will be less columns in my table than the number of fields in the csv file, so I guess I got to mention 'MISSING FIELD VALUES ARE NULL' option. There is another challenge too - I have to skip loading the first two lines from the file to the table.
I have written a big pl/sql proc for doing the same, using utl_file.get_line option, but it is still untested and I would be extremely happy to believe that this can be achieved by creating an external table too.

I have a requirement to import text files which are generated from 3d modelling software xsteel where it records all geometric information and i want to import this information into oracle table.
CREATE TABLE dstv_head ( wo_no VARCHAR2(12),struct VARCHAR2(12),rev_no NUMBER,
mark VARCHAR2(12),pos VARCHAR2(12),grade VARCHAR2(12),qty NUMBER,PROFILE VARCHAR2(24),TYPE VARCHAR2(12),
len NUMBER,width_web NUMBER,width_bottom NUMBER,flange_thk NUMBER,web_thk NUMBER,radius NUMBER,kgm NUMBER,
kgm1 NUMBER,kgm2 NUMBER,bevel_plus NUMBER,bevel_minus NUMBER,holes_yn VARCHAR2(1),holes_v_yn VARCHAR2(1),
hole_x_dim NUMBER,hole_y_dim NUMBER,hole_dia NUMBER,no_of_holes NUMBER)
-- All the data which has to go under specific field for example **9005.nc1 will go into wo_no field, 1239401A will go under struct.
ST
** 9005.nc1 --WO_NO
1239401A - STRUCT
1 -REV_NO
9005 -MARK
9005 --POS
S275JR --GRADE
2 --QTY
[code]....
