I hope I will.

 

You do not need anything exhaustive to copy sqlite database in runtime. It's just C code for copying file, That's It!!!!

I've written a code sample and tested copying '.db' file from 'res' folder to 'shared/data' folder successfully.

 

FILE *src,*dst;

char srcURL[100];
char dstURL[100];
int ch;

sprintf(srcURL,"%s%s",app_get_resource_path(),"ghi.db");
sprintf(dstURL,"%s%s",app_get_shared_data_path(),"ijk.db");

dlog_print(DLOG_DEBUG,"self","%s",srcURL);
dlog_print(DLOG_DEBUG,"self","%s",dstURL);

src=fopen(srcURL,"r");
dst=fopen(dstURL,"w");

while( ( ch = getc(src) ) != EOF )
    fputc(ch, dst);


fclose(src);
fclose(dst);

Seems "How to copy sqlite data/.db file in application at runtime?" query is responsed. Now "Copying a specific table from one database to another database" is quite a different SQL query topic. I would suggest lets leave this thread answered and Have a new beginning in a new post. 'Mark as answer' if the requirement stated in title is taken cared. That would be more convenient for other developers having difficulty on the same scenario.
