erlang下安装支持mysql访问【转】

慧9建

　　下载源码：

svn checkout http://erlang-mysql
-driver.google
code.com/svn/trunk/
erlang-mysql-driver-read-only


下载完后命名目录为"mysql"，进入mysql/src目录对其下的文件
全部进行编译；

建立mysql/ebin目录，把编译好的.beam文件拷贝到ebin中

复制mysql目录到erlang/lib目录下。



启动erlang sehll环境

#erl



连接mysql:

1>mysql:start_link(p1, "localhost", "root", "password", "test").
mysql_conn:620: greeting version "5.0.45" (protocol 10) salt ">H1XKN%k" caps 41516 server char <<8,2,0,0,

mysql_conn:426: fetch <<"use test">> (id <0.49.0>)
{ok,<0.47.0>}
 　　





更新数据操作

2>mysql:fetch(p1,<<"insert into t(id,name)values('12','laja')">>).

mysql_conn:426: fetch <<"insert into t(id,name)values('12','laja')">> (id <0.49.0>)

{updated,{mysql_result,[],[],1,[]}} #1表示影响数




查询数据操作

3> mysql:fetch(p1,<<"select * from t">>).

mysql_conn:426: fetch <<"select * from t">> (id <0.49.0>)

{data,{mysql_result,[{<<"t">>,<<"id">>,11,'LONG'},

                     {<<"t">>,<<"name">>,20,'STRING'}],

                     [12,<<"laja">>]],

                    0,[]}}




连接一切正常，到此结束。
