附近有错误
string strconn = "server=localhost;uid=sa;pwd=sa;database=购物 ";
SqlConnection cn = new SqlConnection(strconn);
string mysql = "select * from Product,Price where Product.PID=Price.PPID ";
if (ddl_pgroup.SelectedIndex.ToString() != "0 ")
{
mysql = mysql + "and pgroup= " + Convert.ToInt16(ddl_pgroup.SelectedIndex.ToString());
}
if (tbx_pid.Text.ToString() != " ")
{
mysql = mysql + "and PID= " + Convert.ToInt16(tbx_pid.Text.ToString());
}
if (tbx_pname.Text.ToString()!= " ")
{
mysql = mysql + "and pname like '% " + tbx_pname.Text.ToString() + "% ' ";
}
if (tbx_pvender.Text.ToString() != " ")
{
mysql = mysql + "and pvender like '% " + tbx_pvender.Text.ToString() + "% ' ";
}
SqlDataAdapter da = new SqlDataAdapter(mysql, cn);
DataSet ds = new DataSet();
da.Fill(ds);
dgd_plist.DataSource = ds;
dgd_plist.DataBind();
cn.Close();
这是一段搜索的代码,但是每次运行的时候,只要用任何的内容来搜索总是出现错误。比如用pname来搜索,就出现“ 'pname ' 附近有语法错误”的问题,哪位高手能指点一下啊,谢谢
------解决方案--------------------string mysql = "select * from Product,Price where Product.PID=Price.PPID ";
==========================================================================
string mysql = "select * from Product,Price where Product.PID=Price.PPID ";
后面先加一个空格,否则拼接肯定错误
