A typical installation of Dameng includes a geometry type that you need to initialize.
Log in to a SQL client as the database administrator and use the following command to initialize the geometry type:
SP_INIT_GEO_SYS(1);
Confirm the geometry type is initialized by issuing the following SQL command:
SELECT SF_CHECK_GEO_SYS;
If the geometry type is initialized, the command will return the following:
LINEID SF_CHECK_GEO_SYS 1 1
