jdbc - Execute anonymous pl/sql block and get resultset in java -

-

i execute anonymous pl/sql , need resultset object. got code can done using cursors inside pl/sql block.

but pl/sql block come database text. can't edit pl/sql block. , return 2 values column names same always. return list of 2 column combination values.

here giving sample pl/sql.

begin  return 'select distinct fundname d, fundname r <table> condition order 1';  exception    when others     return 'select ''not available'' d, ''not available'' r dual'; end;

any reply helpful.

here self contained example of how "execute anonymous pl/sql , resultset object"

import java.sql.callablestatement; import java.sql.connection; import java.sql.drivermanager; import java.sql.resultset; import java.sql.types;  import oracle.jdbc.oracletypes;  public class callplsqlblockwithoneinputstringandoneoutputstringparameterandoneoutputcursorparameter {      public static void main(string[] args) throws exception {          drivermanager.registerdriver(new oracle.jdbc.oracledriver());          // warning: simple example program : in long running application,         // error handlers must clean connections statements , result sets.          final connection c = drivermanager.getconnection("jdbc:oracle:thin:@localhost:1521:xe", "system", "manager");         string plsql = "" +         " declare " +           "    p_id varchar2(20) := null; " +         "    l_rc sys_refcursor;" +         " begin " +         "    p_id := ?; " +         "    ? := 'input parameter = ' || p_id;" +         "    open l_rc " +         "        select 1 id, 'hello' name dual " +         "        union " +         "        select 2, 'peter' dual; " +         "    ? := l_rc;" +         " end;";          callablestatement cs = c.preparecall(plsql);         cs.setstring(1, "12345");         cs.registeroutparameter(2, types.varchar);         cs.registeroutparameter(3, oracletypes.cursor);          cs.execute();          system.out.println("result = " + cs.getobject(2));          resultset cursorresultset = (resultset) cs.getobject(3);         while (cursorresultset.next ())         {             system.out.println (cursorresultset.getint(1) + " " + cursorresultset.getstring(2));         }          cs.close();         c.close();     } }

the above example query "select 1 id, 'hello' name dual union select 2, 'peter' dual;" can replaced query.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
