sqlcpp
SETUP for VISUAL STUDIO 2017
Making it Run with CHAI-3D
- Copy DBManager.cpp / DBManager.h to the project folder from https://github.com/sandeepzgk/sqlcpp
- Right Click the application > Click on Add > Add Existing Items and select the DBManager.cpp and DBManager.h files
- Download SQLITE DLL and def from the link https://sqlite.org/download.html "Precompiled Binaries for Windows" get both x86 and win64 versions.
- Create SQLITE import library from the downloaded sqlite3.def file. for both 32 and 64 bits (needed for different compiler options for chai3d / vs applications) Use "DEVELOPER COMMAND PROMPT FOR VS"
- Ideally the the dll's should be extracted to a folder say "c:\sqlite" and then run the command
lib /DEF:"C:\sqlite\sqlite-dll-win64\sqlite3.def" /OUT:"c:\sqlite\sqlite3-32.lib"in the DEVELOPER COMMAND PROMPT FOR VS This will generate the 32 bit lib files. - Make the 64 bit libs files using /MACHINE toggle like this
lib /DEF:"C:\sqlite\sqlite-dll-win64\sqlite3.def" /OUT:"c:\sqlite\sqlite3.lib" /MACHINE:X64, Ensure the names are different for both the 32 bit and 64 bit. - To include sqlite.h in the Vs project download source code for sqlite3 from https://sqlite.org/download.html "sqlite-amalgamation-xxxxxxx.zip" Extract the zip file and copy sqlite3.h to a directory say for eg:"c:\sqlite" also copy generated sqlite3.lib (in step-2) and sqlite3.dll to the same directory.
- In visual studio in your code add the appropriate folders
- Set additional include directory to sqlite.h file directory. for this ,in the Vs solution explorer take project properties and go to. Configuration Properties–>C++–>General–>set additional directories set it as the directory in which sqlite3.h copied for eg: "c:\sqlite"
- Now set sqlite.lib as linker input. for this ,in the Vs solution explorer take project properties and go to. Configuration Properties–>Linker–>Input and add sqlite3.lib to it. Ensure you have either 32 or 64 bit as you created and named.
- Set sqlite3.lib library directory as additional library for this in the Vs solution explorer take project properties and go to. Configuration Properties–>Linker–>General–>Additional Library Directories set it , for eg:"c:\sqlite"
HOW TO USE THIS
- In your main file, include the header file #include "DBManager.h"
- Get an instance of the class by DBManager *dbmanager = DBManager::GetInstance();
- There are two writes possible with this class, 3a. dbmanager->writeMainData(5.5, "P1", "A", 3, 2, "Y"); 3b. dbmanager->writeSRData("P1",1,12); 3c. dbmanager->writeForceData("Og81",12,1.24,15.55,12.44)
- These writes will add values to the three different tables in the database.
A working example of this code is available at https://github.com/sandeepzgk/chai3d-experiments/tree/SQLIntegration_Test SQLIntegration_Test as a part of the chai3d-experiements repository.

ADDITIONAL IMPORTANT NOTES
-
The code now implements singleton pattern and you can get the instance anywhere
- The filename for the db is test.db which can be changed to anything else
- There is no delay in startup of the code
- this uses detachable threads to write data to the db and only ONE write thread is available
- Before exiting the application just check if isBusy function is returning true or false, if its busy please DO NOT EXIT
- the write call should immediately return control to the main thread, as it has already spawn a write thread to the DB which will kill itself after execution.
EXPLORING THE DB
- Use https://sqlitebrowser.org/ this is a pretty good tool to explore the sqlite database
- You will see two tables MAINDATA and SRDATA tables that contains the data entered by you.
SETUP for UBUNTU
- sudo apt-get install libsqlite3-dev
- sudo apt-get install sqlite3
- use cmake to build the makefile and make that should get you the executable. https://github.com/sandeepzgk/sqlcpp
