APEX and the question: Where have remained my metadata?

Anyone who has ever created a small or large APEX Geo-application, described in the following situation may have experienced before. Each table with an SDO_GEOMETRY column requires a registration in the SDO metadata of the Oracle database. This is an insert in the user-oriented view USER_SDO_GEOM_METADATA and can look like this:

SQL> insert into USER_SDO_GEOM_METADATA (

table_name, column_name
,

diminfo,

 srid) 
 values (
 'GEOTAB' 
 'geometry', 
 sdo_dim_array (sdo_dim_element ('X', -180,180,0.005) 
 sdo_dim_element ('Y', -90,90,0.005)), 
 8307 ); 
 
 Expanding an application in APEX and used for registering the SDO_GEOMETRY column in the metadata of the SQL Workshop and then as far as running without problems.

will then ordinarily be applied also still the same the spatial index and you get the error message ORA-00942: table or view does not exist.

A short

SQL> select * from USER_SDO_GEOM_METADATA where table_name = 'GEOTAB';

returns no results.

 What happened? Where the entry remains in the metadata?

With DBA rights, it is easy to search in the table of the user MDSYS.

SQL> select * from mdsys.sdo_geom_metadata_table;

There is in the column SDO_OWNER then find instead of the expected user (in this example SPATIAL) according to the Web listener used by APEX to either ANONYMOUS, APEX_PUBLIC_USER or HTMLDB_PUBLIC_USER. This is the username of the APEX session, then in the scheme also SDO_GEOMETRY the metadata is registered.

How can this be cleaned up now?

 Ask your DBA to your users UPDATE privileges for the table MDSYS SDO_GEOM_METADATA_TABLE blame.

SQL> grant update on mdsys.sdo_geom_metadata_table;

SDO_OWNER Then change the entry as follows:

SQL> update MDSYS.SDO_GEOM_METADATA_TABLE

set sdo_owner = 'SPATIAL'
where sdo_table_name = ' GEOTAB 'and sdo_owner =' ANONYMOUS ';

 if you check the metadata should now all be alright.
