如何在VB.net中连接oracle数据库

Posted 2023-03-09

在web.config中配置：
’连接oracle
dim
strconnect
as
string
=
system.web.configuration.webconfigurationmanager.connectionstrings("conn").tostring()
dim
conn
as
oledb.oledbconnection
=
new
system.data.oledb.oledbconnection(strconnect)
’返回数据
public
function
gettable(byval
sql)
conn.open()
dim
comm
as
oledb.oledbcommand
=
new
oledb.oledbcommand(sql,
conn)
dim
da
as
oledb.oledbdataadapter
=
new
oledb.oledbdataadapter(comm)
dim
dt
as
system.data.datatable
=
new
system.data.datatable()
da.fill(dt)
conn.close()
return
dt
end
function
’返回受影响的行数
public
function
impactdate(byval
sql)
conn.open()
dim
comm
as
oledb.oledbcommand
=
new
oledb.oledbcommand(sql,
conn)
dim
i
as
integer
=
comm.executenonquery
return
i
end
function 参考技术A 只要引用“System.Data.OracleClient”就可以了
连接字符串示例：
user
id=user;data
source=server/databasename;password=pass;
其他跟
sqlserver
都差不多，只是比如SqlConnection要改成OracleConnection
SqlDataAdapter要改成OracleDataAdapter
SqlCommand
要改成OracleCommand
