用c＃代码插入ms访问另一个数据库的数据库

Question

我使用下面的代码将一个记录从一个数据库插入另一个数据库，但它不起作用。我试过MS-ACCESS 2007中的查询，它工作正常，但从我的C#代码以编程方式调用时不起作用？

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(); 

当我走在MS Access中的的​​内容，它工作正常

它抛出

INSERT INTO语法错误例外线 cmd_insert.ExecuteNonQuery（）;

Answer 1

我发现了一个不同的语法in this Microsoft forum

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(); 

测试了"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存在于CURRENT_DATE reserved keyword。这可以解决用方括号封装字段名称。

顺便说一句，一旦解决了CURRENT_DATE问题，IN语法也可以正常工作。

Answer 2

你缺少 '价值' 在query_insert关键字。

Answer 3

我不是很熟悉ms访问查询，但我认为你不应该使用OleDbDataAdapter。该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(); 

Answer 4

和其他人一样，这是一个SQL语法问题。您缺少VALUES关键字，请看：

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

您的VALUES关键字在哪里？
