我正在尝试填充更多信息以使银行对帐单包含更多信息，因此我决定加入两个表。此查询适用于 SQL 管理工作室。但如果我在 Visual Studio 中使用创建查询和显示数据，它会发送此异常错误
System.Data.SqlClient.SqlException(0x80131904) : Incorrect syntax near '.'.
第 62 行
我的代码是这样的:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.Reporting.WinForms;
namespace TmpZ
{
public partial class BalanceSheet : Form
{
string constring = ConfigurationManager.ConnectionStrings["ConnData"].ConnectionString;
public BalanceSheet()
{
InitializeComponent();
}
private void BalanceSheet_Load(object sender, EventArgs e)
{
}
private void reportViewer1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
if (accountNo1.Text == "")
{
MessageBox.Show("Please Enter Account Number");
}
else
{
DataTable dtb = new DataTable();
dtb = GenerateBankStatement(dtb);
reportViewer1.LocalReport.DataSources.Clear();
ReportDataSource rpd = new ReportDataSource("DataSet1", dtb);
reportViewer1.LocalReport.DataSources.Add(rpd);
reportViewer1.RefreshReport();
}
}
private DataTable GenerateBankStatement(DataTable dt)
{
using (SqlConnection cn = new SqlConnection(constring))
{
try
{
string dateF = Convert.ToDateTime(dateFrom.Text).ToString("dd-MM-yyyy");
string dateT = Convert.ToDateTime(dateTo.Text).ToString("dd-MM-yyyy");
//SqlDataAdapter da = new SqlDataAdapter("SELECT [id] as id, [transaction_desc] as transaction_desc,[credit] as credit, [debit] as debit, [balance] as balance, [transaction_date] as transaction_date FROM transactions WHERE(accountNo1 = '" + accountNo1.Text + "') AND(transaction_date BETWEEN '" + dateF + "' AND '" + dateT + "')", cn);
//SqlDataAdapter da = new SqlDataAdapter("SELECT [id] as id, [transaction_desc] as transaction_desc,[credit] as credit, [debit] as debit, [balance] as balance, [transaction_date] as transaction_date FROM transactions WHERE(accountNo1 = '" + accountNo1.Text + "')", cn);
SqlDataAdapter da = new SqlDataAdapter("SELECT [fullname] as account_info.fullname, [accountNo] as account_info.accountNo, [ccy] as account_info.ccy, [address] as account_info.address, [id] as transactions.id, [transaction_desc] as transactions.transaction_desc, [credit] as transactions.credit, [debit] as transactions.debit, [balance] as transactions.balance, [transaction_date] as transactions.transaction_date FROM transactions CROSS JOIN account_info WHERE(account_info.accountNo = '" + accountNo1.Text + "') AND(transactions.transaction_date BETWEEN '" + dateF + "' AND '" + dateT + "')", cn);
da.Fill(dt);
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
return dt;
}
}
}
第 62 行显示了 SQLDataAdapter。我做错了什么？
最佳答案
你不能在别名中使用 .
SELECT [fullname] as account_info.fullname
我相信这就是你想要的
SELECT account_info.fullname as [fullname]
