sql - Oracle Query Date Range -


This query takes 16 minutes is there a faster way? 

  INIT.MPI_MEMHEAD.MEMIDNUM is selected from INIT.MPI_MEMHEAD at INIT.MPI_AUDHEAD INIT.MPI_AUDHEAD.audrecno = INIT.MPI_MEMHEAD.CAUDRECNO where INIT.MPI_AUDHEAD.audctime +0) & gt; = To_date ('01 -JAN-14 ') and (INIT.MPI_AUDHEAD.audctime + 0) & lt; = To_date ('01-APR-14 ')    
 
 
 First of all, you "( INIT.MPI_AUDHEAD.audctime + 0) & gt; = to_date ('01 -JAN-14 ') and (INIT.MPI_AUDHEAD.audctime + 0) & lt; = to_date ('01 -APR-14') "to" Code> Where INIT.MPI_AUDHEAD.audctime between date '01 -JAN-14 'and date '01 - APR-14'  ".  
 Second, if you have INIT If you want to always select this table in one quarter by MPI_AUDHEAD.audctime, you can change this table in a partition table by auditing it. As mentioned below:  
  create MPI_Oddhead (Audit Date) range by audit (overtime) (less than the Partial payment payment value (TO_DATE ('2014-01-01 00:00:00' , 'Yay-MM-DD hh24: Mile: SS')) Tabspex TBS 01, Partition Part 02 Low Price (TO_DATE ('2014-04-01 00:00:00', 'YAY-MM-DD HH 24: Mile: SS ')) TABLESPACE tbs02,);   
)  
 Third, add an index to the audit.  
 For your reference.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
