Code fucntion insert works well in excel. Code fucntion insert在excel中运行良好。 But code Update is not working.also I tried to run step by step..it executes all but stops at adap.update(ds.tables[0]) saying Syntax error in UPDATE statement. 但是代码更新不起作用。所以我试着一步一步地运行..在adap.update（ds.tables [0]）执行除了停止在UPDATE语句中的语法错误。
exception: System.Data.OleDb.OleDbException was unhandled
HResult=-2147217900
Message=Syntax error in UPDATE statement.

Suppose You have following Data in your workSheet PR 假设您在workSheet PR有以下数据
FirstName LastName Age
johny Depp 55
Statham John 45
Diana bantley 35
then you have to go through this code in your Button Click for Update 然后你必须在Button Click for Update中查看这段代码
conn= new OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=e:\PRTEXT.xls;Extended Properties=Excel 8.0";
conn.Open();
string xlsSheet = "PR$";
adap.UpdateCommand = new OleDbCommand("UPDATE [" + xlsSheet + "] SET FirstName = ?, LastName = ?, Age = ?" +
" WHERE FirstName = "+ ds.Tables[0].Rows[0][0], conn);
adap.UpdateCommand.Parameters.Add("@FirstName", OleDbType.Char, 255).SourceColumn = "FirstName";
adap.UpdateCommand.Parameters.Add("@LastName", OleDbType.Char, 255).SourceColumn = "LastName";
adap.UpdateCommand.Parameters.Add("@Age", OleDbType.Char, 255).SourceColumn = "Age";
//// Updates the first row
ds.Tables[0].Rows[0]["FirstName"] = "john";
ds.Tables[0].Rows[0]["LastName"] = "Statham";
ds.Tables[0].Rows[0]["Age"] = "55";
adap.Update(ds.Tables[0]);
conn.Close();
MessageBox.Show("Updated");
where we give whole Query of update and in where condition we pass value of first index (ie (Zero index) value) , this update value Succesfully by changing our data DataTable Zero Index row. 我们给出整个查询更新和在哪里条件我们传递第一个索引的值（即（零索引）值），这个更新值成功地通过改变我们的数据DataTable零索引行。

kindly change PrimaryColumnIndex which you want to be not change in Excel File. 请更改您希望不在Excel文件中更改的PrimaryColumnIndex 。
Update: 更新：

Update 2 : 更新2：
It is throwing error Because, Space is not supported in Query between Feilds Name. 抛出错误因为，在Feilds Name之间的Query中不支持Space 。
