Load WKT using sql*loader [message #446795] Wed, 10 March 2010 08:31 Go to next message

Hi,

I want to load geometry into a table using sql*loader. My datafile contains geometry defined as WKT http://en.wikipedia.org/wiki/Well-known_text, a standard for geometry and also Oracle has a function called sdo_util.from_wktgeometry.
If I'm using a separate 'insert into' statement using this function in sql*plus, there's no problem. But if I'm using the same function in my control-file for sql*loader import, I get a sql*loader-418 error: "bad datafile for column geometrie".

Does anyone know why and how I can import WKT using sql*loader?

-- data file
id;geometrie
1;POINT(120123.123 485345.789)
2;LINESTRING(123456.01 482543.21, 125764.76 483444.11)

I don't think SQL*Loader supports the mdsys.sdo_geometry datatype. I believe you will need to load the data into a staging table as varchar2 or clob, then insert from the staging table to the target table using sdo_util.from_wktgeometry.

You're right. MDSYS.SDO_GEOMETRY is an object, so it is supported. I fiddled with it a bit and found that the combination of BOUNDFILLER and the EXPRESSION keyword solves the problem, as demonstrated below.

Another difficulty came to my attention:
sdo_util.from_wktgeometry is available since oracle 10g. Since we are dealing with both 10g and 9i, I was wndering if there is a solution to import WKT into a 9i database?

One method that I can think of is to write your own substitute function. I have provided some partial code below. It does not address all posible data and may contain errors. It is just intended to give you the general idea and provide a starting point that you can modify to suit your needs.

Hi,

I'm having difficulties importing large polygons. De controlfile is functioning properly, but the polygondata in the datafile seems to contain too many coordinates. My errorlog:

Record 1: refused error in table GBD_STADSDEEL_GEOMETRIE, column GEOMETRIE_DATA.
field in datafile exceeds maximum length.

Is there a limitation of the maximum of my wkt datastring (or boundfiller)? And how to solve this problem? My contains polygondata of at least 9332 characters.

Does this post:

http://www.orafaq.com/forum/t/157802/43710/

mean that you have found a workaround by loading into a column object or is this still a problem?

Hi Barbara,

we want to be able to serve both WKT and via geometry object. The second one is the 'old' method, which we still have to support. WKT is a new method and more ideal, since it is not only limited to oracle.

If you don't provide a field length, sql*loader uses a default length of 255 characters, so if you use char(9400) that solves the length problem. However, 4000 is the max size for varchar2, so it expects a long or clob and there is some sort of problem with trying to use that with boundfiller. As a workaround, you can create a clob column in your table and use that in your control file and use that as the input parameter instead of the boundfiller. You can then drop the clob column aftr loading if you like. Please see the demo below.

-- test.ctl:
LOAD DATA
INFILE 'gbd_stadsdeel_geometrie.dat'
APPEND INTO TABLE gbd_stadsdeel_geometrie
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '$$'
TRAILING NULLCOLS
(

,SDC_ID DECIMAL EXTERNAL
,SCHAAL DECIMAL EXTERNAL
,GEOMETRIE_DATA CHAR(9400)

)

Hi again,

when trying to import wkt into a table, I discovered that an entire record is ignored if the geometrie column is empty. I have tried to use NULLIF, but in combination with EXPRESSION it generates an error. I do want to record to be imported and a null for the geometry.

Any suggestions? thank you

The problem is that the from_wktgeometry function does not accept a null value as an input parameter, as shown below.

SCOTT@orcl_11g> select sdo_util.from_wktgeometry('') from dual;
select sdo_util.from_wktgeometry('') from dual
       *

ORA-29532: Java call terminated by uncaught Java exception:
java.lang.NullPointerException
ORA-06512: at "MDSYS.SDO_UTIL", line 177


SCOTT@orcl_11g>


A workaround is to use a wrapper function to handle the null value, as shown below.

SCOTT@orcl_11g> create or replace function from_wktgeom_wrapper
  2    (p_data in clob)
  3    return	  mdsys.sdo_geometry
  4  as
  5  begin
  6    if p_data is null
  7    then return null;
  8    else return sdo_util.from_wktgeometry (p_data);
  9    end if;
 10  end from_wktgeom_wrapper;
 11  /

Function created.

mmm, from_wktgeometry has some various drawbacks (null values and long strings), which seem common situations to me.

Thanks anyhow Barbara. Smile
