------解决方案--------------------
1、
CC.ExSql("UPDATE tb_News SET newsTitle = '" + this.txtNewsTitle.Text + "', newsContent = '" + this.TextBox1.Text + "', newsStyle = '" + this.ddlNewsStyle2.SelectedValue.ToString() + "',issueDate = '" + DateTime.Now.ToString("yyyy-MM-dd") + "' WHERE ID = '" + Request.QueryString["id"] + "'");

 2、
CC.ExSql("UPDATE tb_News SET newsTitle = '" + this.txtNewsTitle.Text + "', newsContent = '" + this.TextBox1.Text + "', newsStyle = '" + this.ddlNewsStyle2.SelectedValue.ToString() + "',issueDate = '" + DateTime.Now.ToString("yyyy-MM-dd") + "' WHERE ID = " + Request.QueryString["id"] + "");
------解决方案--------------------
string strSQL = "UPDATE tb_News SET newsTitle = '" + this.txtNewsTitle.Text + "', newsContent = '" + this.TextBox1.Text + "', newsStyle = '" + this.ddlNewsStyle2.SelectedValue.ToString() + "',issueDate = '" + DateTime.Now.ToString("yyyy-MM-dd") + "' WHERE ID = " + Request.QueryString["id"];

Response.Write(strSQL); //页面上输出SQL语句，然后看看那个地方不对，就行了

CC.ExSql(strSQL);
