问题 I'm trying to ether get rid of a real world many-to-many relationship (and just feeling stupid for not being able to) or find the proper way to input it into Access. I've tried several junction table setups and only seem to pass the many-to-many problem on to another table. Here is an abbreviated sample of the two tables: Table 1: Amp_Number Amp_S.Name 103 Rag1 194 Osd4 230 Lew6 321 Ooi4 550 Qwd3 629 Crd5 687 Rab4 879 Pra2 Table 2: Plas_Number Plas_Amp 55 Rab4 82 Osd4 & Qwd3 & Lew6 94 Rab4 &

问题 I keep getting an error when I attempt to insert values into a Access database. The error is syntactic, which leads to the following exception: OleDbException was unhandled Syntax error in INSERT INTO statement. private OleDbConnection myCon; public Form1() { InitializeComponent(); myCon = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\File.mdb"); } private void insertuser_Click(object sender, EventArgs e) { OleDbCommand cmd = new OleDbCommand(); myCon.Open(); cmd

问题 My Java application works well on two of my colleague's computers, however it will not run on mine. The application reads a spreadsheet, creates tables in access from it and then compares them. The application is able to read and create the tables, but will not compare them. The error I am getting is java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Undefined function 'replace' in expression. I have read the other threads on this but wasn't able to gain much insight. Since we

We have access to the Microsoft Office Suite and therefore most of our projects are created in Access even though there are better solutions out there. We recently received access to Visual Studio 2013 and I am interested in converting some of our more heavily used tools into VB.NET projects. I have a good understanding of VBA after using it for so many years, however, converting to VB.NET is definitely a
