The <columnOverride> element is used to change certain attributes of an introspected database column from their calculated values. This element is an optional child element of the <table> element.
| Attribute | Description |
|---|---|
| column | The column name of the introspected. |
| Attribute | Description |
|---|---|
| property | The name of a Java property to be used. If not specified, Abator will generate properties based on the column name. For example, if a table has a column named STRT_DTE, Abator will generate the property name as either STRT_DTE or strtDte based on the value of the "useActualColumnNames" property (see the description of the <table> element for more information). This property could be used to rename the column "startDate" |
| javaType | The fully qualified Java Type of the property for this column. This
can be used to override the type calculated by the JavaTypeResolver
if required. For some databases, this is necessary to handle
"odd" database types (e.g. MySql's unsigned bigint type
should be mapped to java.lang.Object). |
| jdbcType | The JDBC Type (INTEGER, DECIMAL, NUMERIC, VARCHAR, etc.) for the column.
This can be used to override the type calculated by the JavaTypeResolver
if required. For some databases this is necessary to handle JDBC driver
quirks (e.g. DB2's LONGVARCHAR type should be mapped to VARCHAR for iBATIS). |
| typeHandler | A user defined type handler that should be used for this column.
This should be the fully
qualified name of a class that implements iBATIS'
TypeHandler or TypeHandlerCallback
interface (TypeHandlerCallback is simpler to implement).
If unspecified, or blank,
then iBATIS will use the default type facility for handling types.
Important: Abator does not verify that this type handler exists,
or is valid. Abator simply inserts this value at the appropriate places
in the generated SQL Map configuration file.
|
| delimitedColumnName | Specifies whether the column name should be delimited in the generated SQL.
Abator will automatically delimit the column name if the name contains a space,
so this override is only necessary when the column name is forces to a certain
case, or when the column name is a reserved word in the database.
When "true", the The delimiter characters are specified on the <abatorContext> element. The default value is false. However, Abator will automatically delimit column names that contain a space, so no override is necessary in that case. |
