Notes:
Attribute |
Description |
---|---|
Entity |
|
ApiNeeded |
Indicate whether or not APIs should be generated. Valid values are Y or N. A default set of APIs are generated if Y is passed. For
example in the ABC_CUSTOMER_ORDER_LINE tables, the application creates
the following APIs when the database extension jar file is generated:
These APIs can be accessed as services using the Service Definition Framework. |
AuditRequired |
If set to Y, an audit record for this entity is created. |
HasHistory |
This flag indicates whether the custom table can have a history table associated with it. The default value is N. If the flag is set to Y, the appropriate scripts for generating database scripts for creating and altering the history table is generated by dbverify. For a custom table, the HasHistory flag must be set to Y for generating history tables. However, if a Parent relationship is defined in the entity XML, this flag is copied from the parent table definition, and all child entities cannot override this flag. |
Prefix |
The prefix added to your custom tables. It is recommended that you do not use a prefix starting with Y. |
TableName |
The name given to your custom table. |
KeyType |
Optional. The valid value is Random. When the value is set to Random, the logic used to generate primary keys for the table results in random primary keys rather than sequential primary keys being generated. That is, when KeyType=”Random”, two random digits are included in the primary keys. For example, the format of generated primary keys is YYYYMMDDHHRRMM(SS)NNNNNNNN, where RR represents the two random digits. |
Entity/Attributes/Attribute |
|
ColumnName |
The names of the column that comprise the table. |
DataType |
The data type of the column. Valid data types are given in the install_dir/repository/datatypes/datatypes.xml file. Note: BLOB datatype is not supported.
|
CompressionSupported |
Optional. Attribute used to indicate whether or not the data compression is supported for this column. Valid values are True or False. If True compression support is enabled. Note: If the data inserted into
a column has both CompressionSupported and UseCompression attributes
set to True, then this attribute should not
be set back to False. Doing so would result
in all compressed data being retrieved without any decompression.
|
UseCompression |
Optional. Attribute used to compress data for this column. Valid values are True or False. If True data is compressed. Note: The value of this attribute should be set to True only
if the CompressionSupported attribute is set to True.
|
QueryAllowed |
Optional. Attribute used to enable a compressible column to be used for queries in a List API. Valid values are True or False. If True the column can be used for queries in the List APIs. Note: If the value of the CompressionSupported
attribute is set to true then the value of this attribute should also
be set to True.
|
DefaultValue |
Default value for the column. |
Description |
A description of the columns that could be used in Javadocs or ERD. |
Nullable |
Optional. Attribute used to describe the nullable value of a field. Default is false. Nullable=true is allowed for all columns except Primary Key Attributes and Entity Relationships. |
XMLName |
Optional. XML name of the attribute, if it is different from the name of the attribute. Note: If ColumnName
is specified using a non-ASCII character set, this attribute is required.
Choose a name that does not conflict with the base extension. It is recommended that you use Extn as a prefix. It is also strongly recommended that you use the same convention for arriving at the XMLName as the base product does: Make each letter following the underscore in the column name upper case, and the rest lower case. Then, remove the underscores. Thus, Extn_Item_Id should be: ExtnItemId. |
Name |
Mandatory. The name of the database class. |
Entity/PrimaryKey |
|
Name |
Name of the unique index created for the primary key. Note: The name of the primary key in the extension
XML should end with _PK.
|
ColumnName |
The name of the table column that is identified as the primary key. |
Entity/Indices/Index |
|
Name |
The index name. This value cannot exceed 18 characters. |
Unique |
This key is present only for custom entities. Valid values are True or False. If True a unique index is created. |
AllowCompressedColumns |
Optional. If True, the index is allowed to contain columns marked with CompressionSupported attribute set to True. |
Column/ Name |
The table column name associated with the index. |
Entity/Parent |
|
ParentTableName |
Name of the other table this entity has foreign key relationship. |
XMLName |
The XML name of the parent attribute. It should start with the prefix mentioned in the parent table. By default the parent table name is assumed. |
Parent/Attribute Level |
|
ParentColumnName |
Column name in the parent table. Note: To create relationships among entities, the data type of parent column must be of type CHAR or VARCHAR. |
ColumnName |
Column name in this custom entity. |
Entity/ForeignKeys/ForeignKey |
|
ParentTableName |
The name of the table with which the entity has a foreign key relationship. |
XMLName |
XML representation of the element name. By default the parent table name is assumed. |
Entity/ForeignKeys/ForeignKey/Attribute |
|
ParentColumnName |
Column name of the parent table. Note: To create foreign keys among entities, the data type of parent column must be of type CHAR or VARCHAR. |
ColumnName |
Column name in this custom entity. |
Entity/AuditReferences/Reference |
|
ColumnName |
Reference Column name in the audit table. |
