OracleCommand + multiple query

Question

I'm making some backup scripts using dbms_metadata.get_dll and and let's say i have a result like that ([...] - i've cut some info, cause it's long):
CREATE TABLESPACE "TEST" DATAFILE
'E:\ORACLEXE\ORADATA\TEST.DBF' SIZE [...]
CREATE TABLE "SYSTEM"."ORACUSTOM"
(     "ID" NUMBER,
     "NAME" VARCHAR2(20),
     PRIMARY KEY ("ID")
USING INDEX [...] TABLESPACE "TEST"
Now I wish to restore it, but if I;m loading the whole text into OracleCommand, got error:
ErrorORA-02180: invalid option for CREATE TABLESPACE
it;s because there is no separation between CREATE TABLE statement, however if i put a semicolor ; before CREATE TABLE - exactly after the last character of CRAETE TABLESPACE command, got:
ErrorORA-00911: invalid character
Is it possible to run it in one OracleCommand (.ExecuteNonQuery), do I need to use some other separation char?
Thx

I believe what you are trying to do is execute all these commands in a single DB round trip. Off the top of my head, there are a couple solutions. You can encapsulate all the commands in a stored procedure or you can use anonymous PL/SQL to batch these commands together.
The first solution is pretty self-explanatory. The second solution would involve some code and encapsulating the commands you want to execute between a BEGIN...END; PL/SQL block. You can also bind parameters, such as the following sample:
string cmdtxt = "BEGIN " +
"OPEN :1 for select ename, deptno from emp where deptno = 10; " +
"OPEN :2 for select ename, deptno from emp where deptno = 20; " +
"OPEN :3 for select ename, deptno from emp where deptno = 30; " +
"END;";
//No need to change the CommandType. Leave it as CommandType.Text
cmd.CommandText = cmdtxt;
//Bind REF Cursor parameters
//Select employees in department 10
OracleParameter p1 = cmd.Parameters.Add("refcursor1", OracleDbType.RefCursor);
p1.Direction = ParameterDirection.Output;
//Select employees in department 20
OracleParameter p2 = cmd.Parameters.Add("refcursor2", OracleDbType.RefCursor);
p2.Direction = ParameterDirection.Output;
//Select employees in department 30
OracleParameter p3 = cmd.Parameters.Add("refcursor3",
OracleDbType.RefCursor);
p3.Direction = ParameterDirection.Output;
//Execute batched statement in one round trip
cmd.ExecuteNonQuery();
