SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT
The following example validates the geometry objects stored in the SHAPE column
of the COLA_MARKETS table. The example includes the creation of the result table.
For this example, a deliberately invalid geometry was inserted into the table before
the validation was performed.
-- Is a layer valid? (First, create the result table.)
CREATE TABLE val_results (sdo_rowid ROWID, result varchar2(1000));
-- (Next statement must be on one command line.)
CALL SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT('COLA_MARKETS','SHAPE','VAL_RESULTS');
Call completed.
SQL> SELECT * from val_results;
