    <p>Hope this will be helpful. </p> <p>When the <code>Table</code> class is initialized, all the input values will be initialized. When <code>getSelectQuery</code> method is called, based on inputs select query will be formed. And <code>populatePreparedSt</code> will be called to set PreparedStatement. Finally based on the inputs, you set in constructor of <code>Table</code>, you will get the query and result.</p> <p>Table class:</p> <pre><code>public class TableRow { private String attibute1; private String attibute2; private int id; // getter and setters public final String selectQuery = " SELECT ID, ATTIBUTE1, ATTIBUTE2 FROM TABLEROW "; public CECardLogRow(int id, String attibute1, String attibute2) { this.id = id; this.attibute1 = attibute1; this.attibute2 = attibute2; } public String getSelectQuery () { StringBuilder sql = new StringBuilder(); boolean whereClauseAdded = false; sql = sql.append(selectQuery); if (id &gt; -1) { sql.append(" WHERE ID = ? "); whereClauseCt++; } if (attibute1 != null &amp;&amp; attibute1.trim() != "") { sql.append(whereClauseAdded ? " AND " : " WHERE "); sql.append(" ATTIBUTE1 = ? "); } if (attibute2 != null &amp;&amp; attibute2.trim() != "") { sql.append(whereClauseAdded ? " AND " : " WHERE "); sql.append(" ATTIBUTE2 = ? "); } return sql.toString(); } public void populatePreparedSt (PreparedStatement ps) { int i = 1; if (id &gt; -1) { ps.setInt(i++, id); } if (attibute1 != null &amp;&amp; attibute1.trim() != "") { ps.setString(i++, attibute1); } if (attibute2 != null &amp;&amp; attibute2.trim() != "") { ps.setString(i++, attibute2); } } } </code></pre> <p>Calling method:</p> <pre><code>public List&lt;TableRow&gt; getData (int id, String attibute1, String attibute2) { List&lt;TableRow&gt; rows = new ArrayList&lt;TableRow&gt;(); Connection con = null; PreparedStatement ps = null; ResultSet rs = null; try { TableRow row = new TableRow(id, attibute1, attibute2); String sql = row.getSelectQuery(); con = global.getConnection(); // get connection ps = con.prepareStatement(sql); row.populatePreparedSt(ps); rs = ps.executeQuery(); while (rs.next()) { TableRow row = new TableRow(); // get data row.setId(rs.getInt("ID"));// and so on rows.add(tableRow); } } catch (SQLException sqe) { throw sqe; } finally() { // closeConnection } return rows; } </code></pre>

    1. COI think people you have got me wrong. I have made an entity class as EntityBo . This class will have all the fields of the tables . Now i'll have one more helper class which will populate the fields in the EntityBo class . Now i have populated this entity class also . After this in the helper class we need a method which will dynamically build the sql query . So basically i am stuck over here to make a method which will build a query dynamically based on the input attributes populated .

    2. COThe query will be some what like this :- SELECT * from CCMS.USER_ACT_AUDIT where CLIENT_ID = ‘GUI’ AND USER_ID = ‘pagi@yahoo.co.in’ AND ACTION = ‘searchParties’ with ur . The attributes mentioned in the query here will be populated in the entity class and based on these attributes the query will be made dynamically . So i just need a method to build the query dynamically .

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
