Alternatively, model classes can be automatically generated by iciql using the model generation tool. Please see the [tools](tools.html) page for details.\r
\r
-### Supported Data Types\r
-<table>\r
+### Configuration Requirements and Limitations\r
+\r
+1. Your model class **must** provide a public default constructor.\r
+2. Only the specified types are supported. Other types such as arrays and custom types are not supported.\r
+3. Triggers, views, and other advanced database features are not supported.\r
\r
+### Fully Supported Data Types\r
+The following data types can be used for all iciql expressions.\r
+<table>\r
+<tr><th colspan="2">All Databases</th></tr>\r
<tr><td>java.lang.String</td>\r
<td>VARCHAR *(length > 0)* or TEXT *(length == 0)*</td></tr>\r
\r
<tr><td>java.util.Date</td>\r
<td>TIMESTAMP</td></tr>\r
\r
-<tr><td>byte []</td>\r
-<td>BLOB</td></tr>\r
-\r
-<tr><td>java.lang.Enum.name()</td>\r
-<td>VARCHAR *(length > 0)* or TEXT *(length == 0)*<br/>*EnumType.STRING*</td></tr>\r
+<tr><td>java.lang.Enum.name()<br/>*default type*</td>\r
+<td>VARCHAR *(length > 0)* or TEXT *(length == 0)*<br/>*EnumType.NAME*</td></tr>\r
\r
<tr><td>java.lang.Enum.ordinal()</td>\r
<td>INT<br/>*EnumType.ORDINAL*</td></tr>\r
<tr><td>java.lang.Enum implements<br/>*com.iciql.Iciql.EnumId.enumId()*</td>\r
<td>INT<br/>*EnumType.ENUMID*</td></tr>\r
\r
+<tr><th colspan="2">H2 Databases</th></tr>\r
+<tr><td>java.util.UUID</td>\r
+<td>UUID</td><tr/>\r
+\r
</table>\r
\r
**NOTE:**<br/>\r
The reverse lookup used for model generation, SQL type -> Java type, contains more mappings.<br/>\r
Please consult the `com.iciql.ModelUtils` class for details. \r
\r
-### Unsupported Types\r
-- Java primitives (use their object counterparts instead)\r
-- array types\r
-- custom types\r
+### Partially Supported Data Types\r
+The following data types can be mapped to columns for all general statements <u>BUT</u> these field types may **not** be used to specify **compile-time** *clauses or constraints*.\r
+\r
+<table>\r
+<tr><td>byte []</td>\r
+<td>BLOB</td></tr>\r
+\r
+<tr><td>boolean</td>\r
+<td>BIT</td></tr>\r
+ \r
+<tr><td>byte</td>\r
+<td>TINYINT</td></tr>\r
+ \r
+<tr><td>short</td>\r
+<td>SMALLINT</td></tr>\r
+ \r
+<tr><td>int</td>\r
+<td>INT</td></tr>\r
+ \r
+<tr><td>long</td>\r
+<td>BIGINT</td></tr>\r
+ \r
+<tr><td>float</td>\r
+<td>REAL</td></tr>\r
+ \r
+<tr><td>double</td>\r
+<td>DOUBLE</td></tr>\r
+\r
+</table>\r
\r
-### Configuration Rules\r
-1. field mappings must be Objects not primitives\r
-2. the model class must have a default public constructor\r
+#### Partially Supported Data Types Example\r
+%BEGINCODE%\r
+class Primitives {\r
+ @IQColumn(primaryKey = true)\r
+ int id;\r
+ \r
+ @IQColumn\r
+ String name;\r
+ \r
+ public Primitives() {\r
+ }\r
+ \r
+ public Primitives(int id, String name) {\r
+ this.id = id;\r
+ this.name = name;\r
+ } \r
+}\r
+ \r
+Primitives p = new Primitives();\r
+\r
+// the following expressions compile, but will throw iciql runtime exceptions\r
+db.from(p).where(p.id).is(100).selectFirst();\r
+db.from(p).where(p.id).atLeast(10).select();\r
+\r
+// the following expressions will work as expected\r
+db.from(p).select();\r
+db.from(p).where("id = ?", 100).selectFirst();\r
+db.from(p).where("id >= ?", 10).select();\r
+db.insert(new Primitives(150, "test"));\r
+db.update(new Primitives(150, "modified"));\r
+db.delete(new Primitives(150, "test"));\r
+%ENDCODE%\r
\r
-### Configuration Limitations\r
-Triggers, views, and other advanced database features are unimplemented.\r
\r
## Annotation Configuration\r
The recommended approach to setup a model class is to annotate the class and field declarations.\r
### How does it work?\r
If you choose to use versioning, iciql will maintain a table within your database named *_iq_versions* which is defined as:\r
\r
- CREATE TABLE _IQ_VERSIONS(SCHEMANAME TEXT NOT NULL, TABLENAME TEXT NOT NULL, VERSION INT NOT NULL)\r
+ CREATE TABLE _IQ_VERSIONS(SCHEMANAME VARCHAR(255) NOT NULL, TABLENAME VARCHAR(255) NOT NULL, VERSION INT NOT NULL)\r
\r
This database table is automatically created if and only if at least one of your model classes specifies a *version* > 0.\r
\r
#### Db.executeQuery Approaches\r
There may be times when the hybrid approach is still too restrictive and you'd prefer to write straight SQL. You can do that too and use iciql to build objects from your ResultSet, but be careful:\r
\r
-1. Make sure to _select *_ in your query otherwise db.bindResultSet() will throw a RuntimeException\r
+1. Make sure to _select *_ in your query otherwise db.buildObjects() will throw a RuntimeException\r
2. There is no model class type checking nor field type checking. \r
