MySQL嵌入式版本的小程序例子_MySQL

bitsCN.comMySQL嵌入式版本越来越式微了。碰巧有个小应用用到了它，顺便记录一下。文档可以参考http://dev.mysql.com/doc/refman/5.6/en/libmysqld-example.html，看起来年久失修的样子，没法一看就懂。希望下面这个简化的步骤可以起到点作用。1. 下载代码并且进行版本编译。这个还比较简单，文档说的也很靠谱。$ cmake . -DCMAKE_INSTALL_PREFIX=/home/mysql -DWITH_EMBEDDED_SERVER=1$ make clean$ make -j 8 $ make install2. 写个小程序$ lsGNUmakefile main.cc my.cnf具体代码就看附件好了，其实很简单。$ make3. 安装好MySQL，初始化一下$ cd /home/mysql$ scripts/mysql_install_db --defaults-file=/home/mysql/my.cnf4. 启动小程序$ ./main附件：# This assumes the MySQL software is installed in /usr/local/mysql#inc := /usr/local/mysql/include/mysql#lib := /usr/local/mysql/lib# If you have not installed the MySQL software yet, try this insteadtopdir := /home/mysql/mysql-5.5.35inc := $(topdir)/includelib := $(topdir)/libmysqldCXX := g++CPPFLAGS := -I$(inc) -D_THREAD_SAFE -D_REENTRANTCXXFLAGS := -g -WallLDFLAGS := # You can change -lmysqld to -lmysqlclient to use the# client/server libraryLDLIBS = -L$(lib) -lmysqld -lm -lcrypt -ldl -lz -lrtifneq (,$(shell grep FreeBSD /COPYRIGHT 2>/dev/null))# FreeBSDLDFLAGS += -pthreadelse# Assume LinuxLDLIBS += -pthreadendif# This works for simple one-file test programssources := $(wildcard *.cc)objects := $(patsubst %cc,%o,$(sources))targets := $(basename $(sources))all: $(targets)clean:rm -f $(targets) $(objects) *.core---#include #include #include using namespace std;const char *server_options[] = / { "mysql_test", "--defaults-file=my.cnf", NULL };int num_elements = (sizeof(server_options) / sizeof(char *)) - 1;const char *server_groups[]= { "libmysqld_server", "libmysqld_client", NULL};bool is_server_started= false;MYSQL *MySQL= NULL;const char *db= NULL;void start_server(){ cout reconnect= 1; return rc;}void output_rows(MYSQL_RES *res){ MYSQL_ROW row; unsigned long n = 0; while ((row= mysql_fetch_row(res)) != 0) { mysql_field_seek(res, 0); for (unsigned int i= 0 ; i 登录后复制bitsCN.com
