JAVA中数据类型的sql转换

Question

我正在运行我的程序，出现了以下错误：

'[Microsoft][ODBC SQL Server Driver][SQL Server]Disallowed implicit conversion from data type char to data type money, table 'OJT.dbo.Patients', column 'pTotalDue'. Use the CONVERT function to run this query'

我该怎么修？有人能帮我吗

这是我的密码：

private void btnInsertActionPerformed(java.awt.event.ActionEvent evt) {
        PreparedStatement pstmt = null;
        try {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        String url = "jdbc:odbc:OJT_dsn";
        String user = "******";
        String pass = "******";
        String sql = "INSERT INTO dbo.Patients" 
                + "(pIDNo,pLName,pFName,pMI,pSex,pStatus,pTelNo,pDocID,pAddr,pStreet,pBarangay,pCity,pProvince,pLnameKIN,pFNameKIN,pMIKIN,pRelationKIN,pTotalDue)"
                + "VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
        Connection connection = DriverManager.getConnection(url, user, pass);
        pstmt = connection.prepareStatement(sql);
        pstmt.setString(1, txtPatientID.getText());
        pstmt.setString(2, txtpLName.getText());
        pstmt.setString(3, txtpFName.getText());
        pstmt.setString(4, txtpMI.getText());
        pstmt.setString(5, txtSex.getText());
        pstmt.setString(6, txtStatus.getText());
        pstmt.setString(7, txtpTel.getText());
        pstmt.setString(8, txtpDoctor.getText());
        pstmt.setString(9, txtStreetNo.getText());
        pstmt.setString(10, txtStreetName.getText());
        pstmt.setString(11, txtBarangay.getText());
        pstmt.setString(12, txtCity.getText());
        pstmt.setString(13, txtProvince.getText());
        pstmt.setString(14, txtLnameKIN.getText());
        pstmt.setString(15, txtFNameKIN.getText());
        pstmt.setString(16, txtMIKIN.getText());
        pstmt.setString(17, txtRelation.getText());
        pstmt.setString(18, txtTotal.getText());
        pstmt.executeUpdate();
        JOptionPane.showMessageDialog(rootPane, "Patient Added!");
        }catch (Exception ex) {
            JOptionPane.showMessageDialog(this, ex.getMessage());
        }
    }

Answer 1

你应该使用pstmt.setDouble(...);

pstmt.setDouble(18, Double.parseDouble(txtTotal.getText()));

Answer 2

它在错误中写道

Disallowed implicit conversion from data type char to data type money

pTotalDue不是char。您需要设置数字类型值

使用BigDecimal。使用任何原语迟早会导致精度问题

Answer 3

这段代码使用的是JDBC-ODBC桥驱动程序，要配置桥驱动程序，请确保正确配置了系统DSN

对于Windows来说就是这样

控制面板>；管理工具>；数据源（ODBC）>；您的系统DSN设置 司机

或者使用瘦驱动程序来编写代码
