[分享]用數(shù)據(jù)源(用數(shù)據(jù)源(ODBC)創(chuàng)建數(shù)據(jù)庫連接DSN設(shè)置)創(chuàng)建數(shù)據(jù)庫連接DSN設(shè)置

Asp連接數(shù)據(jù)庫推薦用ACCESS+MSSQL /

ASP+ACCESS

Conn.open=”provider=microsoft.jet.oledb.4.0;data source=”&server.mappath(“數(shù)據(jù)庫路徑”)

ASP+MSSQL

Conn.open=”provider=sqloledb;server=127.0.0.1;uid=sa;pwd=admin;database=wm”

ASP+MYSQL

conn.open="driver={MYSQLODBC 3.51 DRIVER};uid=root;pwd=;database=HR_MOVE;server=127.0.0.1"

ASP+SQLITE

A conn.open="DSN=SQL_WM;DRIVER={SQLite3 ODBC Driver}"

B conn.open="DRIVER={SQLite3 ODBC Driver};DATABASE=D:\SQLITE\WWWW"

ASP+PostgreSQL conn.open="DRIVER={PostgreSQL ANSI};server=127.0.0.1;uid=itnows;pwd=000000;database=test1"

php連接數(shù)據(jù)庫推薦用PHP+MYSQL

PHP+ACCESS

$conn = new com("ADODB.Connection"); $connstr = "DRIVER={Microsoft Access Driver (*.mdb)};

DBQ=" . realpath("workermove.mdb");

$conn->Open($connstr); $rs = new com("ADODB.RecordSet"); $rs->Open(SQL語句,$conn,1,1);

PHP+MSSQL

$connstr = "DRIVER={SQL SERVER};SERVER=127.0.0.1\GSQL;UID=SA;PWD=ADMIN;DATABASE=WORKMOVE";

$conn->Open($connstr); ?> PHP+MYSQL

PHP+SQLITE

$db = @sqlite_open("sqlite.db"); 也可調(diào)用odbc方式連接sqlite 詳見PHP手冊(cè)

PHP+PostgreSQL

$conn_string =@pg_connect("host=127.0.0.1 port=5432 dbname=test1 user=itnows password=000000")

關(guān)于MYSQL與SQLITE共同提取5151筆資料時(shí)間比較次數(shù) MYSQL SQLITE (單位，毫秒)

1 467.59 325.57 69.6% 2 509.15 333.10 65.4% 3 487.99 326.93 66.9% 4 511.35 352.47 68.9% 5 500.42 328.93 65.7%

補(bǔ)充： SQLite數(shù)據(jù)庫在ASP下使用，先要裝ODBC的驅(qū)動(dòng)。才能set conn=server.createobject("adodb.connection")。

到這邊下載sqlite的odbc驅(qū)動(dòng)程序安裝下就可以使用了

connstr="driver={sqlite3 odbc driver};database="&server.MapPath("data.db3")
set conn=server.CreateObject("adodb.Connection")
conn.open connstr
