如何把数组的值插入到数据库 c#

string

connectStr

=

"User

Id=scottPassword=tigerData

Source="

OracleConnection

conn

=

new

OracleConnection(connectStr)

OracleCommand

command

=

new

OracleCommand()

command.Connection

=

conn

conn.Open()

2.通过循环写入大量的数据

for

(int

i

=

0

i

<

recc

i++)

{

string

sql

=

"insert

into

dept

values("

+

i.ToString()

+

","

+

i.ToString()

+

","

+

i.ToString()

+

")"

command.CommandText

=

sql

command.ExecuteNonQuery()

}

//设置一个数据库的连接串

string

connectStr

=

"User

Id=scottPassword=tigerData

Source="

OracleConnection

conn

=

new

OracleConnection(connectStr)

OracleCommand

command

=

new

OracleCommand()

command.Connection

=

conn

//到此为止，还都是我们熟悉的代码，下面就要开始喽

//这个参数需要指定每次批插入的记录数

command.ArrayBindCount

=

recc

//在这个命令行中,用到了参数,参数我们很熟悉,但是这个参数在传值的时候

//用到的是数组,而不是单个的值,这就是它独特的地方

command.CommandText

=

"insert

into

dept

values(:deptno,

:deptname,

:loc)"

conn.Open()

//下面定义几个数组,分别表示三个字段,数组的长度由参数直接给出

int[]

deptNo

=

new

int[recc]

string[]

dname

=

new

string[recc]

string[]

loc

=

new

string[recc]

//

为了传递参数,不可避免的要使用参数,下面会连续定义三个

//

从名称可以直接看出每个参数的含义,不在每个解释了

OracleParameter

deptNoParam

=

new

OracleParameter("deptno",

OracleDbType.Int32)

deptNoParam.Direction

=

ParameterDirection.Input

deptNoParam.Value

=

deptNo

command.Parameters.Add(deptNoParam)

OracleParameter

deptNameParam

=

new

OracleParameter("deptname",

OracleDbType.Varchar2)

deptNameParam.Direction

=

ParameterDirection.Input

deptNameParam.Value

=

dname

command.Parameters.Add(deptNameParam)

OracleParameter

deptLocParam

=

new

OracleParameter("loc",

OracleDbType.Varchar2)

deptLocParam.Direction

=

ParameterDirection.Input

deptLocParam.Value

=

loc

command.Parameters.Add(deptLocParam)

//在下面的循环中,先把数组定义好,而不是像上面那样直接生成SQL

for

(int

i

=

0

i

<

recc

i++)

{

deptNo[i]

=

i

dname[i]

=

i.ToString()

loc[i]

=

i.ToString()

}

//这个调用将把参数数组传进SQL,同时写入数据库

command.ExecuteNonQuery()

//把数据写入数据库

function res() {

//获取输入值(myname和mymail是两个文本框的id)

var uname = document.getElementById("myname").value

var umail = document.getElementById("mymail").value

//数据库连接对象

var con = new ActiveXObject("ADODB.Connection")

//连接字符串

var str = "DRIVER={SQL SERVER}SERVER=(local)uid=sapwd=123456database=xslt"

//打开数据源

con.Open(str)

//sql语句

var sql = "insert into xslt(name,mail) values(''" + uname + "'',''" + umail + "'')"

try {

//执行sql语句

con.Execute(sql)

//关闭连接

con.Close()

//转向成功页面

catch (e) {

alert(e)

}
