do we have to say connection.commit explicitly after prepared statement execution

Murray9654Jul 28 2015 — edited Jul 28 2015

Hi i am inserting a record using database connection. I am obtaining connection from datasource. After inserting a record using preparedStatement.executeUpdate() do i have to explicitly write connection.commit() ?

Hi,

The sdo_gtype of your sample geometry is 3002 which suggests you are storing x, y, z values. i.e. heights in the z.
Based on your explanation of the data, it sounds like you should be using Linear Referencing - read about it here (
http://docs.oracle.com/cd/E11882_01/appdev.112/e11830/sdo_lrs_concepts.htm#BABIIFFH).
Note that use of Linear Referencing requires an Oracle Spatial license - Locator is not enough.

SDO_LRS has a variety of functions/operators which will help you achieve your goal.
E.g. SDO_LRS.LOCATE_PT

Hi,

Thanks for the tip.
I used the LOCATE_PT function with the SDO_UTIL.GETVERTICES function and it works.

My query is (for hisghway id = '1000' and km = 5000):

select li.*, t.*
from HIGHWAYS li , table( sdo_util.getvertices( SDO_LRS.LOCATE_PT( li.geom, 5000 ) )) t
where li.id = '1000'
;
