HOW to use HAVING COUNT(*) with hibernate

Question

I need to create a query and I need COUNT(*) and HAVING COUNT(*) = x.

I\'m using a work around that uses the CustomProjection

Answer 1

If someone needs to do it in grails it would be like:

projections {
    groupProperty("id")
    sqlGroupProjection(...)
    rowCount()
}

Where sqlGroupProjection is available since 2.2.0

/**
 * Adds a sql projection to the criteria
 * 
 * @param sql SQL projecting
 * @param groupBy group by clause
 * @param columnAliases List of column aliases for the projected values
 * @param types List of types for the projected values
 */
protected void sqlGroupProjection(String sql, String groupBy, List columnAliases, List types) {
    projectionList.add(Projections.sqlGroupProjection(sql, groupBy, columnAliases.toArray(new String[columnAliases.size()]), types.toArray(new Type[types.size()])));
}
