DataAdapter.Fill（），错误出现“附近的语法不正确”）'“

Question

When retrieving a datatable from database using the following code in ASP.Net & C#: The database is located in my local machine.

string connectionString = @"Data Source=CCS90; Initial Catalog=Ribo; Trusted_Connection=True;";
SqlConnection myConn = new SqlConnection(connectionString);
myConn.Open();       

SqlCommand sqlCommand = new SqlCommand("SELECT * FROM PUR_POHEADER WHERE POID = @POID", myConn);
sqlCommand.Parameters.Add("@POID", SqlDbType.Int);
sqlCommand.Parameters["@POID"].Value = Convert.ToInt32(request.ReferenceNo);

DataSet DS = new DataSet();
SqlDataAdapter AD = new SqlDataAdapter(sqlCommand, myConn);
//AD.Fill(DS);
AD.Fill(DS, "POTABLE");   //Error arise at this place
DataTable DT = DS.Tables[0];
myConn.Close();

When compiler comes to the line AD.Fill(DS, "POTABLE"); , error occurs at Incorrect syntax near ') . What may be the reason?

Answer 1

You may try with

AD.Fill(DS);

instead of

AD.Fill(DS,"PORTABLE");

Also try:

SqlDataAdapter AD = new SqlDataAdapter(sqlCommand);

instead of

SqlDataAdapter AD = new SqlDataAdapter(insertStatement, myConn);

Answer 2

You create a SqlCommand with a SELECT statement and then you don't use it. What is insertStatement ? Surely you should be using sqlCommand .

Answer 3

Problem is here:

SqlDataAdapter AD = new SqlDataAdapter(insertStatement, myConn);

replace it with:

SqlDataAdapter AD = new SqlDataAdapter(sqlCommand);

and also you are using this overload i think:

AD.Fill(DS, "NameOfDataTable");

then you can access it like this:

DataTable DT = DS.Tables["NameOfDataTable"];

insetad of using 0 index.
