Your code: "SELECT * FROM user WHERE UName='" & nm & "'AND Pwd='" & pass & "'" Should be: "SELECT * FROM user WHERE UName='" & nm & "' AND Pwd='" & pass & "'" However, you should use parameterized queries to avoid the possibility of SQL injection attacks. Something like this: sql = "SELECT * FROM user WHERE UName=@nm AND Pwd=@pass" cmd = New OleDbCommand(sql, cn) cmd.Parameters.AddWithValue("@nm", TextBox1.Text) cmd.Parameters.AddWithValue("@pass", TextBox2.Text) cmd.CommandType = CommandT

I think you can use backticks to allow it, but suggest changing that table name to Users or something else –Ryan J Jan 31 '15 at 18:49 Thanks A lot it work –Mohamed Mostafa Jan 31 '15 at 18:53 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted "User" is a reserved word for Access.

caused by something not that complex. As the case always is once you have the solution. https://blogs.msdn.microsoft.com/spike/2008/07/17/syntax-error-in-from-clause-when-using-text-based-datasources/ So I thought I would share some of the things that I've come across, and hopefully tha {"Syntax error in FROM clause."} when using text based datasources ★★★★★★★★★★★★★★★ http://www.ibm.com/support/docview.wss?uid=swg21352053 Michael Aspengren - MSFTJuly 17, 20080 0 0 0 This is also one of the issues that I have seen a few times. What happens here is that customer uses *.csv or *.xls or any text file as a data source and connects to it using .Net and OleDb. The error reported from the framework when issuing a SELECT is: {"Syntax error in FROM clause."} The most common reason for this is that error in from the *.csv or *.xls file name contains a space. No space and all is well. The reason for this is that the file name is the table name, and as such, no spaces are allowed and should be enclosed in square brackets ie. [table name]. Let’s show by example. Create a *.csv file in C:\Temp with the following content. CID;FNAME;LNAME 1;John;Smith 2;Peter;Johnson 3;Steve;Lloyd Then save it as Test.csv and then as Test Test.csv. Create a new .Net console application and just edit the Program.cs file to look like this. using System; using System.Text; using System.Data.OleDb; using System.Data; class Program { static void Main(string[] args) { // With space string fName = @"C:\Temp\Test Test.csv"; // Without space //string fName = @"C:\Temp\Test.csv"; // Get the dir out of the full path. string path = fName.Substring(0, fName.LastIndexOf(@"\")); string cString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties='text;HDR=Yes;FMT=CSVDelimited'"; OleDbConnection oc = new OleDbConnection(cString)
(troubleshooting) Problem(Abstract) Problem Number Error Error number -3989587 DMS-E-GENERAL, A General Exception has occurred during operation 'prepare request'. DMS-E-DBPARSER, The underlying database detected an error during processing of the SQL request. [Microsoft][ODBC Text Driver] Syntax error in FROM clause. when querying an ODBC datasource using the Microsoft ODBC Text Driver. Solution Description This error is due to an issue with the ODBC driver. Microsoft have documented this issue in their Knowledge Base articles #Q124322, Q125959 and Q124319. Please contact Microsoft for further information on this issue. As a workaround it may be possible to Qualify the Tables Less in the Catalog Tables dialog window. It may also be necessary to change the delimiter type in the ODBC drivers options, and to use Escape Metacharacters when retrieving the data. This option is also set in the Options for the ODBC driver. The problem is due to the driver not supporting quoted schema's or tables thus to eliminate the problem the attach must be made using the connection parameter DELIMIT=COL. Microsoft offers the following as a workaround. Please contact Microsoft for further information on this technique. These workarounds are not set within Impromptu but are for the Driver. Method 1: Name the range something other than "Database" or "Table." Method 2: If you are accessing data from a Microsoft Excel 5.0 workbook that contains a global range named "Database" or "Table," define it as a local range name, such as "Sheet1!Database." Note that making the name a local one will cause the table name to be displayed with the sheet name and then the range name: Sheet1!Database. Method 3: Add brackets ([) around the words "Database" or "Table." For example, to select all records from a table called Database, follow these steps: a. In Microsoft Query, click the SQL button on the toolbar. This displays the SQL dialog box. b. In the dialog box, type the following SQL statement: SELECT * FROM [Database] c. Choose OK. A message will appear stating that the query cannot be represented graphically. d. Choose Yes to continue. This displays only the Data pane in the query window. Resolving the problem This error is due to an issue with the ODBC driver. Microsoft have documented this issue in their Knowledge Base articles #Q124322, Q125959 and Q124319.
