## Release History

### Current Release

<span class="warning">iciql is undergoing rapid development so api and configuration are subject to change from release to release</span>

**%VERSION%** ([zip](http://code.google.com/p/iciql/downloads/detail?name=%ZIP%)|[jar](http://code.google.com/p/iciql/downloads/detail?name=%JAR%)) &nbsp; *released %BUILDDATE%*

- Added support for single column subquery *select name, address from user_table where user_id in (select user_id from invoice table where paid = false)*
- Added support for left outer join (Github/backpaper0)

**0.7.10** &nbsp; *released 2012-01-27*

- Fixed default String value bug where a default empty string threw an IndexOutOfBounds exception

**0.7.9** &nbsp; *released 2012-01-24*

- Added toParameter() option for SET commands and allow generating parameterized UPDATE statements<br/>
String q = db.from(t).set(t.timestamp).toParameter().where(t.id).is(5).toSQL();<br/>
db.executeUpdate(q, new Date());

**0.7.8** &nbsp; *released 2012-01-11*

- Replaced non-threadsafe counter used for assigning AS identifiers in JOIN statements with an AtomicInteger
- Prevent negative rollover of the AS counter
- Added optional alias parameter to *Query.toSQL* and *QueryWhere.toSQL* to force generated statement to prefix an AS identifier or, alternatively, the tablename.  
    - Query.toSQL(boolean distinct, K alias)
    - QueryWhere.toSQL(boolean distinct, K alias)
- Fixed bug in Query.select(Z z) which assumed that Z must always be an anonymous inner class which may not always be true.  This allows for specifying an existing alias to force table or identifier usage in the generated select list.  This is very useful for DISTINCT JOIN statements where only the columns of the primary table are of interest.

**0.7.7** &nbsp; *released 2012-01-05*

- added *Query.toSQL()* and *QueryWhere.toSQL()* methods which, when combined with the following new methods, allows for generation of a parameterized, static sql string to be reused with a dynamic query or a PreparedStatement.  
    - QueryCondition.isParameter()
    - QueryCondition.atLeastParameter()
    - QueryCondition.atMostParameter()
    - QueryCondition.exceedsParameter()
    - QueryCondition.lessThanParameter()
    - QueryCondition.likeParameter()
    - QueryCondition.isNotParameter()
- Disallow **declaring and explicitly referencing** multiple instances of an enum type within a single model.<br/>A runtime exception will be thrown if an attempt to use where/set/on/and/or/groupBy/orderBy(enum) and your model has multiple fields of a single enum type.

**0.7.6** &nbsp; *released 2011-12-21*

- Iciql now tries to instantiate a default value from an annotated default value IFF the field object is null, it is specified *nullable = false*, and a defaultValue exists.  This only applies to *db.insert* or *db.update*.

**0.7.5** &nbsp; *released 2011-12-12*

- Iciql now identifies wildcard queries and builds a dynamic column lookup.  Otherwise, the original field-position-based approach is used.  This corrects the performance regression released in 0.7.4 while still fixing the wildcard statement column mapping problem. 

**0.7.4** &nbsp; *released 2011-12-06*

- Disallow **declaring and explicitly referencing** multiple primitive booleans in a single model.<br/>A runtime exception will be thrown if an attempt to use where/set/on/and/or/groupBy/orderBy(boolean) and your model has multiple mapped primitive boolean fields.
- Added list alternatives to the varargs methods because it was too easy to forget list.toArray()<br/>
*Db.executeQuery(Class&lt;? extends T&gt; modelClass, String sql, List&lt;?&gt; args)*<br/>
*Db.executeQuery(String sql, List&lt;?&gt; args)*<br/>
*Query.where(String fragment, List&lt;?&gt; args)*<br/>
- Fixed inherited JaQu bug related to model classes and wildcard queries (select *).<p/>
Iciql maps resultset columns by the index of the model class field from a list.  This assumes that *all* columns in the resultset have a corresponding model field definition.  This works fine for most queries because iciql explicitly selects columns from the table (*select alpha, beta...*) when you execute *select()*.  The problem is when iciql issues a dynamic wildcard query and your model does not represent all columns in the resultset: columns and fields may fail to correctly line-up.<p/>
Iciql now maps all fields by their column name, not by their position.
