Format

SDO_GEOR_ADMIN.maintainSysdataEntries() RETURN SDO_STRING2_ARRAY;

Description

Checks the USER_SDO_GEOR_SYSDATA view for any invalid entries, and takes corrective action as appropriate.

Parameters

None.

Usage Notes

This function performs the same checks as the SDO_GEOR_ADMIN.checkSysdataEntries function, and it takes the corrective action that is appropriate (if any). For each of the following errors, the function does the following:

• The RDT name is not unique. If you are connected as a user without DBA role, no action is taken; if you are connected as a user with DBA role, duplicate RDTs are renamed so that their names are unique.

• The GeoRaster table does not exist. The entry is deleted.

• The GeoRaster column does not exist. The entry is deleted.

• The GeoRaster objects does not exist. The entry is deleted.

• The GeoRaster object is non-empty or nonblank, but the RDT does not exist. The entry is deleted.

• Duplicate GeoRaster objects exist (that is, one or more non-unique combinations of RDT and raster ID). The entry is deleted.

If you execute this procedure as a user with DBA role, then the maintenance is performed in all the schemas in the database. Otherwise, the maintenance is performed in the current schema.

The USER_SDO_GEOR_DATA and ALL_SDO_GEOR_SYSDATA views are described in GeoRaster System Data Views (xxx_SDO_GEOR_SYSDATA).

Examples

The following example checks the USER_SDO_GEOR_SYSDATA view for invalid entries, and performs corrective action as appropriate.

DECLARE
  ret SDO_STRING2_ARRAY;
BEGIN
  ret:=sdo_geor_admin.MAINTAINSYSDATAENTRIES;
  for i in 1..ret.count loop
    dbms_output.put_line(ret(i));
  end loop;
END;
/
The RDT name GEOR_TEST1.RDT2 is renamed to GEOR_TEST1.RDT1!
The sysdata entry (SCHEMA=GEOR_TEST1 RDT=dt1 RID=1) is deleted!
