Executing PL/SQL Begin/End procedure from Oracle JDBC thin driver

I am trying to create Oracle PL/SQL procedures and execute them via Oracle JDBC (thin driver). Here is the full PL/SQL script:

begin
for i in (select owner, constraint_name, table_name from all_constraints where owner = 'SCHEMA' and status = 'ENABLED') LOOP
execute immediate 'alter table SCHEMA.'||i.table_name||' disable constraint SCHEMA.'||i.constraint_name||'';
end loop;
end;
/
begin
for i in (select table_name from all_tables where owner = 'SCHEMA') LOOP
execute immediate 'truncate table SCHEMA.'||i.table_name||'';
end loop;
end;
/
begin
for i in (select owner, constraint_name, table_name from all_constraints where owner = 'SCHEMA' and status = 'DISABLED') LOOP
execute immediate 'alter table SCHEMA.'||i.table_name||' enable constraint SCHEMA.'||i.constraint_name||'';
end loop;
end;
/

In java I am splitting on '/' so each begin end block is executed in a separa开发者_Python百科te statement. The java code to execute the statement is:

CallableStatement c = dbc.getConnection().prepareCall(sqlStatement);
c.executeUpdate();

I'm receiving the following error:

java.sql.SQLSyntaxErrorException: ORA-00933: SQL command not properly ended
ORA-06512: at line 3

How do I format this and execute the PL/SQL in JDBC?

Updated: To clarify, all three statements are executed without the '/' delimiter that is split on.

Updated: The oracle server is the following version: Oracle Database 11g Release 11.2.0.1.0 - 64bit Production

In the "enable /diable" constraint you shouldn't add the schema name (your'SCHEMA).

From the manual: ALTER TABLE

Your example:

begin
    for i in (select owner, constraint_name, table_name
              from   all_constraints
              where  owner = 'SCHEMA'
              and    status = 'ENABLED')
    loop
        execute immediate 'alter table SCHEMA.' || i.table_name ||
                          ' disable constraint ' || i.constraint_name;
    end loop;
end;

Test Query

select ac.constraint_name, ac.table_name, ac.status, ac.owner
from   all_constraints ac
where  ac.owner = 'HR'
and    ac.constraint_name = 'EMP_SALARY_MIN'

Result

CONSTRAINT_NAME                TABLE_NAME                     STATUS   OWNER
------------------------------ ------------------------------ -------- --------------------------------------------------------------------------------
EMP_SALARY_MIN                 EMPLOYEES                      ENABLED  HR

Correct dynamic sql

begin
    execute immediate 'alter table HR.EMPLOYEES disable constraint EMP_SALARY_MIN';
end;

Previous query result

CONSTRAINT_NAME                TABLE_NAME                     STATUS   OWNER
------------------------------ ------------------------------ -------- --------------------------------------------------------------------------------
EMP_SALARY_MIN                 EMPLOYEES                      DISABLED HR
