C#连接存储过程提示找不到表0
下面是sql server 2008的存储过程
程序代码：
USE [MENTOR]
GO
/****** Object: StoredProcedure [dbo].[ShowInfo] Script Date: 05/23/2017 20:50:30 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[ShowInfo]
(
@Tables varchar(2000),--表名
@PrimaryKey varchar(500),--排序的字段名
@Sort varchar(500) = NULL,--待排序的字段名
@CurrentPage int = 1,--当前页数
@PageSize int = 5,--每页记录数
@Fields varchar(2000) = '*',--查询条件
@Filter varchar(1000) = NULL,
@Group varchar(1000) = NULL
)
AS
/**//*默认排序*/
IF @Sort IS NULL OR @Sort = ''
SET @Sort = @PrimaryKey
DECLARE @SortTable varchar(1000)
DECLARE @SortName varchar(1000)
DECLARE @strSortColumn varchar(1000)
DECLARE @operator char(2)
DECLARE @type varchar(1000)
DECLARE @prec int
/**//*设定排序语句.*/
IF CHARINDEX('DESC',@Sort)>0
BEGIN
SET @strSortColumn = REPLACE(@Sort, 'DESC', '')
SET @operator = '<='
END
ELSE
BEGIN
IF CHARINDEX('ASC', @Sort) = 0
print '1'
print REPLACE(@Sort, 'ASC', '')
SET @strSortColumn = REPLACE(@Sort, 'ASC', '')
print @strSortColumn
SET @operator = '>='
print @operator
END
IF CHARINDEX('.', @strSortColumn) > 0
BEGIN
SET @SortTable = SUBSTRING(@strSortColumn, 0, CHARINDEX('.',@strSortColumn))
SET @SortName = SUBSTRING(@strSortColumn, CHARINDEX('.',@strSortColumn) + 1, LEN(@strSortColumn))
END
ELSE
BEGIN
SET @SortTable = @Tables
SET @SortName = @strSortColumn
print @SortTable
print @SortName
END
程序代码：
public partial class Form1 : Form
{
int ToatalCountRecornd;//总记录数
int PageItem = 100;//每页显示的条数
int CurrentPage = 1;//当前页数
public Form1()
{
InitializeComponent();
}
public void Form1_Load(object sender, EventArgs e)
{
Binddatawithpage(1);
}
private string strcon = @"server=.;database=MENTOR;uid=sa;pwd=sophianlove2600";
private string strproc = @"ShowInfo";

private DataTable getdata(string conn, string strProcedure, int pageIndex, int pageSize)
{
using (SqlConnection connetion = new SqlConnection(conn))
{
SqlCommand command = new SqlCommand(strproc, connetion);
= CommandType.StoredProcedure;
//存储过程参数
command.Parameters.Add("@Tables", SqlDbType.VarChar, 255).Value = "MYINFO";
command.Parameters.Add("@PrimaryKey", SqlDbType.VarChar, 255).Value = "useid";
command.Parameters.Add("@Sort", SqlDbType.VarChar, 255).Value = "useid";
command.Parameters.Add("@Fields", SqlDbType.NVarChar, 1000).Value = "*";
command.Parameters.Add("@PageSize", SqlDbType.Int).Value = pageSize.ToString();
command.Parameters.Add("@CurrentPage", SqlDbType.Int).Value = pageIndex.ToString();
if (connetion.State != ConnectionState.Open)
{
connetion.Open();
}
try
{
//填充数据
SqlDataAdapter da = new SqlDataAdapter(command);
DataSet ds = new DataSet();
da.Fill(ds);
//获取总记录数
ToatalCountRecornd = Convert.ToInt32(ds.Tables[0].Rows[0][0]);
//返回数据集
return ds.Tables[0];
}
catch (SqlException err)
{
MessageBox.Show(err.Message);
return null;
}
finally
{
connetion.Close();
}
}
}
/// <summary>
///
/// </summary>
/// <param name="INdex"></param>
private void Binddatawithpage(int INdex)
{
toolStripTextBox1.Text = INdex.ToString();
dataGridView1.DataSource = getdata(strcon, strproc, INdex,100);
toolStripLabel1.Text = ToatalCountRecornd.ToString() ;
}
}
刚开始执行几次正常，几次之后就提示找不到表0了。
想问一下为什么会突然找不到表0了？
