How to import data into a varray using sqlldr


I am trying to import data into Oracle database using sqlldr.

I am using this documentation, but not successfully: sqlldr and sqlldr2

Decribing what I am doing:

create the varray type and the table:

CREATE OR REPLACE TYPE fv_integer_varray_12 AS VARRAY(12) OF INTEGER NOT NULL;

CREATE OR REPLACE TYPE VC_Array_MInteger_12 AS Object (
  fv_array fv_integer_varray_12,
  MEMBER FUNCTION   typeDimension   RETURN NUMBER ,
  MEMBER FUNCTION typeName RETURN VARCHAR2);
/  

CREATE TABLE fv_varray_12 (
id NUMBER, 
fv fv_integer_varray_12,
PRIMARY KEY (id)
);

Create the control file:

options (errors=9999999, rows=5)
load data
 characterset WE8MSWIN1252
 infile '<path>'
 badfile '<path>'
 discardfile '<path>'
 into table fv_varray_12
 fields terminated by " "
( id, fv VARRAY COUNT(12) (fv))

The data to be load is:

8 18 29 38 9 16 15 14 16 18 16 13 15 
9 22 31 32 8 13 18 10 15 18 16 13 13 

When I try to load it through the command:

sqlldr user/pass control=imp_fv_12dim.ctl

I get the error:

SQL*Loader-403: Referenced column not present in table FV_VARRAY_12.

But it is not true as both the id and fv columns are there.

There must be something wrong in my control file. How can I fix it?


Solution

  • You are just missing the keyword CONSTANT:

    fv VARRAY COUNT(CONSTANT 12) (fv)
    

    That is missing from the example in the documentation (but then their data also look odd); but it is shown as required in the count_spec syntax diagram, which is linked to from the 12c documentaion on loading VARRAYs - but is also available in earlier versions of the documentation too..

    With your sample data and just that modification to the control file:

    options (errors=9999999, rows=5)
    load data
    characterset WE8MSWIN1252
    infile 'imp_fv_12dim.dat'
    badfile 'imp_fv_12dim.bad'
    discardfile 'imp_fv_12dim.dis'
    into table fv_varray_12
    fields terminated by " "
    ( id,
      fv VARRAY COUNT(CONSTANT 12) (fv)
    )
    

    then it works:

    > sqlldr user/pass control=imp_fv_12dim.ctl

    And querying shows the data:

    column fv format a80
    select * from fv_varray_12;
    
            ID FV
