Changing all DIMINFO sdo_tolerance values for all metadata records in one go.
Someone contacted me about having to change all the tolerances in their user_sdo_geom_metadata due to a need to change each sdo_tolerance value from 0.005 (1cm) to 0.0005 (1mm) meters.
SET serveroutput ON SIZE unlimited DECLARE cursor meta IS SELECT TABLE_NAME, column_name, diminfo FROM user_sdo_geom_metadata FOR UPDATE OF diminfo; BEGIN FOR rec IN meta loop IF (rec.diminfo IS NOT NULL AND rec.diminfo.COUNT >= 2) THEN dbms_output.put_line(rec.TABLE_NAME || '.' || rec.column_name || ' diminfo tolerances are ' || ' X=' || rec.diminfo(1).sdo_tolerance || ' Y=' || rec.diminfo(2).sdo_tolerance); rec.diminfo(1).sdo_tolerance := rec.diminfo(1).sdo_tolerance; -- 0.05; rec.diminfo(2).sdo_tolerance := rec.diminfo(2).sdo_tolerance; -- 0.05; UPDATE user_sdo_geom_metadata SET diminfo = rec.diminfo WHERE CURRENT OF meta; END IF; END loop; commit; END; /
I hope this helps someone out there…
