I am preparing to send free time to MongoDB research recently, so there will be a series of articles to record this process. Download the Windows 32 version 1.2.1: Export -- dbpath E: \ lenkydatasource \ MongoDB \ 1.2.1 \ lenkytest \ dB -- Port 55555 from the official website and execute this file to start the MongoDB service program. The decompressed file also contains the C ++ header file and library file.
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ mongodb-win32-i386-1.2.1 \ include
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ mongodb-win32-i386-1.2.1 \ Lib use them to write the MongoDB client program:
First, check for the MongoDB library files provided in boostand db-win32-i386-1.2.1.zip.
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ mongodb-win32-i386-1.2.1 \ Lib \ clients client. Lib
It is compiled using vs2008 + boost_000035_0, so you are too lazy to re-compile MongoDB. Therefore, you can use the corresponding vs2008 + boost_000035_0 compiling environment to download boost_000035_0 from the boost official website. Compile boost in two steps:
1. Run E: \ lenkydatasource \ MongoDB \ 1.2.1 \ boost_1_35_0 \ boost_1_35_0 \ tools \ jam \ build_dist.bat 2: copying data to E: \ lenkydatasource \ MongoDB \ 1.2.1 \ boost_1_35_0 \ release, then execute:
Cd e: \ lenkydatasource \ MongoDB \ 1.2.1 \ boost_1_35_0 \ boost_1_35_0
Bjam.exe link = static threading = multi variant = release runtime-link = static -- without-Python -- toolset = Many Lib libraries are generated after the msvc-9.0 is complete, such as the libboost_program_options-vc90-mt-gd-1_35.lib, copy all the Lib library files (search for the Lib keyword) to the E: \ lenkydatasource \ MongoDB \ 1.2.1 \ boost_1_35_0 \ boost_1_35_0 \ uselib directory (the uselib directory is created by myself) next, use vs2008 to create the project test, including the file first. CPP, and make the following settings:
1. Tools --> options --> projects and solutions --> VC ++ directory
Add the corresponding include file:
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ boost_1_35_0 \ boost_1_35_0
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ mongodb-win32-i386-1.2.1 \ include \ Mongo
Add the corresponding library file:
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ boost_1_35_0 \ boost_1_35_0 \ uselib
E: \ lenkydatasource \ MongoDB \ 1.2.1 \ mongodb-win32-i386-1.2.1 \ lib2, project --> Properties (Alt + F7) --> Configure properties --> C/C ++ --> code generation --> Runtime Library
Select multiple threads (/mt), which is static. Do not use DLL. Compile and execute. Result:
Time: 10.797 s
Insert finished
Time: 0.453 s
Query finished
Time: 0.094 s
I have encountered many problems in the process of removing finished. After one solution, the correct process is like the above, and I do not know what is missing or not described. First. cpp file content:
// First. cpp # include <iostream> # include "client/dbclient. H" # pragma comment (Lib, "expose client. lib ")
# Pragma comment (Lib, "wsock32.lib") using namespace STD; int main (INT argc, const char ** argv ){
Int I;
Clock_t start, finish;
String errmsg;
String table = "Test. Test ";
Int record = 100000;
Mongo: dbclientconnection conn; // connect DB Server
If (! Conn. Connect (string ("127.0.0.1: 55555"), errmsg )){
Cout <"couldn't connect to server:" <errmsg <Endl;
Return-1;
}
// Insert Test Data
Start = clock ();
For (I = 0; I <record; I ++ ){
Mongo: bsonobjbuilder query;
Query <"user" <I <"PWD" <I <"Age" <I;
Query <"email" <I <"Address" <I <"phone" <I;
Conn. insert (table, query. OBJ ());
}
Finish = clock ();
Cout <"time:" <(double) (finish-Start)/clocks_per_sec <"S" <Endl;
Cout <"insert finished" <Endl; // query Test Data
Start = clock ();
{
Mongo: bsonobjbuilder query;
// Query. append ("user", 1 );
Auto_ptr <Mongo: dbclientcursor> cursor = conn. Query (table, query. OBJ ());
While (cursor-> more ()){
Mongo: bsonobj OBJ = cursor-> next ();
// Cout <obj. jsonstring () <Endl;
}
}
Finish = clock ();
Cout <"time:" <(double) (finish-Start)/clocks_per_sec <"S" <Endl;
Cout <"query finished" <Endl; // remove Test Data
Start = clock ();
{
Mongo: bsonobjbuilder query;
// Query. append ("user", 1 );
Conn. Remove (table, query. OBJ ());
}
Finish = clock ();
Cout <"time:" <(double) (finish-Start)/clocks_per_sec <"S" <Endl;
Cout <"Remove finished" <Endl; // waiting
Cin> errmsg;
Return 0;
}
