Set long 10000
je příkaz SQL*PLUS, nikoli standardní SQL, proto jste narazili na chybu.
Příklad
ResultSet rs = stmt.executeQuery("SELECT DBMS_METADATA.GET_DDL('TABLE','YOUR_OBJECTS','JAY') as ddl FROM dual");
while(rs.next()){
System.out.println(rs.getString(1));
}
Výstup
CREATE TABLE "JAY"."YOUR_OBJECTS"

"OBJECT_NAME" VARCHAR2(128) NOT NULL ENABLE,
"SUBOBJECT_NAME" VARCHAR2(128),

Při spuštění stejného příkazu na SQL*PLUS jsem získal částečné DDL.
SQL> SELECT DBMS_METADATA.GET_DDL('INDEX','SYS_IL0000092981C00086$$','JAY') as ddl FROM dual;
DDL
--------------------------------------------------------------------------------
CREATE UNIQUE INDEX "JAY"."SYS_IL0000092981C00086$$" ON "JAY"."SYS_EXPORT_SCH
Zde mohu získat celé DDL nastavením SET LONG
ALE dostanu kompletní výstup na Java Application.
