我使用以下代码将记录从一个数据库插入到另一个数据库，但它不起作用。我尝试了查询，MS-ACCESS 2007它工作正常，但是从我的代码以编程方式调用时它不起作用C#？

string query_insert = "INSERT INTO Questionnaires_Table(BranchName,Factor,Region,Branch_ID,Current_Date,No_Employees) "
    + "SELECT BranchName,Factor,Region,Branch_ID,Current_Date,No_Employees "
    + "FROM Questionnaires_Table IN '" + dialog.FileName + "' Where Branch_ID = " + textBox1.Text ;

dbConnDest.Open();


   OleDbDataAdapter dAdapter = new OleDbDataAdapter();
   OleDbCommand cmd_insert = new OleDbCommand(query_insert, dbConnDest);

   dAdapter.InsertCommand = cmd_insert;
   cmd_insert.ExecuteNonQuery();

dbConnDest.Close();

当我获取query_insertin ms 访问的内容时，它工作正常

它抛出

cmd_insert.ExecuteNonQuery() 行中的 INSERT INTO 语法错误异常；

您在 query_insert 中缺少“值”关键字。

我在这个 Microsoft 论坛中发现了不同的语法

  INSERT INTO [AccessTable] SELECT * FROM [MS Access;DATABASE=D:\My Documents\db2.mdb].[Table2]

所以你可以试试这个

string query_insert = "INSERT INTO Questionnaires_Table " +
    "(BranchName,Factor,Region,Branch_ID,[Current_Date],No_Employees) " +
    "SELECT BranchName,Factor,Region,Branch_ID,[Current_Date],No_Employees " +
    "FROM [MS Access;DATABASE=" + dialog.FileName  + "].Questionnaires_Table " +
    "Where Branch_ID = @branch";

dbConnDest.Open();
OleDbCommand cmd_insert = new OleDbCommand(query_insert, dbConnDest);
cmd_insert.Parameters.AddWithValue("@branch", textBox1.Text);
cmd.ExecuteNonQuery();

经测试"Provider=Microsoft.ACE.OLEDB.12.0;"

然而，随着更多的研究，很明显给出的语法错误是由于保留关键字CURRENT_DATE 的存在。这可以通过用方括号封装字段名称来解决。

顺便说一句，一旦解决了 CURRENT_DATE 的问题，IN 语法也能正常工作。

就像其他人说的那样，那是一个 SQL 语法问题。您缺少 VALUES 关键字，请查看：

INSERT INTO TABLENAME (COL1, COL2, COL2) VALUES (VAL1, VAL2, VAL3)

您的 VALUES 关键字在哪里？

我不太熟悉 ms 访问查询，但我认为您不应该使用 OleDbDataAdapter。代码应类似于以下内容：

string query_insert = "INSERT INTO Questionnaires_Table(BranchName,Factor,Region,Branch_ID,Current_Date,No_Employees) "
    + "SELECT BranchName,Factor,Region,Branch_ID,Current_Date,No_Employees "
    + "FROM Questionnaires_Table IN '" + dialog.FileName + "' Where Branch_ID = " + textBox1.Text ;

dbConnDest.Open();

OleDbCommand cmd_insert = new OleDbCommand(query_insert, dbConnDest);
cmd_insert.ExecuteNonQuery();

dbConnDest.Close();
