Body
I use Spring Jdbc Template that way: <pre><code>public List<User> getUsersForGrid(int rows, int page, String sidx, String sord) { int fromRecord = 0; int toRecord = 0; toRecord = page * rows; fromRecord = (page - 1) * rows; StringBuilder sqlB = new StringBuilder(); sqlB.append("SELECT user_id, username "); sqlB.append("FROM users "); sqlB.append("WHERE :fromRecord <= rownum AND rownum <= :toRecord "); sqlB.append("ORDER BY %s %s "); String sql = String.format(sqlB.toString(), sidx, sord); MapSqlParameterSource params = new MapSqlParameterSource(); params.addValue("fromRecord", fromRecord); params.addValue("toRecord", toRecord); List<Map<String, Object>> rsRows = this.jdbcTemplate.queryForList(sql .toString(),params); List<User> users = new ArrayList<User>(); for (Map<String, Object> row : rsRows) { BigDecimal id = (BigDecimal) row.get("user_id"); String username = (String) row.get("username"); User user = new User(id.intValue(), username); users.add(user); } return users; } </code></pre> and get <code>java.sql.SQLException: Invalid column type</code> sidx is column nate("user_id" for example) sord is asc/desc When pass no params(execute only <pre><code> sql.append("SELECT user_id, username "); sql.append("FROM users "); </code></pre> ) everything is OK. Update: Works with: <pre><code>sqlB.append("WHERE ? <= rownum AND rownum <= ? "); </code></pre> and <pre><code>this.jdbcTemplate.queryForList(sql.toString(),new Object[]{fromRecord, toRecord}); </code></pre> Seems like problem with Spring MapSqlParameterSource and named parameters. I use Spring 3.1.3 DB is Oracle 11.2 <pre><code>describe users; Name Null Type ------------------------------ -------- --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- USER_ID NOT NULL NUMBER USERNAME NOT NULL VARCHAR2(40) PASSWORD NOT NULL VARCHAR2(20) ENABLED NOT NULL NUMBER </code></pre>

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.
