When a user creates an XML column, ArcSDE stores corresponding XML document, index, and tag information in a series of system tables. The business table created
by the user contains an integer ID in the XML column. ArcSDE uses this ID to refer to the following system tables:
 Database
Schema
Diagram
When an XML column is added to a business table, a row is added to the
XML columns table. This table occurs once in each ArcSDE database.
| COLUMN_ID |
SE_INT32_TYPE |
NOT NULL |
The XML column's identifier and the table's primary key
This value is assigned by ArcSDE at the time the XML column is created. |
| REGISTRATION_ID |
SE_INT32_TYPE |
NOT NULL |
The identifier of the business table containing the XML column
A foreign key to the ArcSDE table registry |
| COLUMN_NAME |
SE_STRING_TYPE |
NOT NULL |
The name of the XML column in the
business table |
| INDEX_ID |
SE_INT32_TYPE |
NULL |
The identifier of the XPath index associated with the XML column, if one exists.
A foreign key to the XML indexes table |
| MINIMUM_ID |
SE_INT32_TYPE |
NULL |
The value of the initial number used in
the business table's XML column to identify individual XML documents |
| CONFIG_KEYWORD |
SE_STRING_TYPE |
NULL |
The DBTUNE configuration keyword whose parameters determine how the XML document, index tables, and
text indexes created on those tables are defined in the database |
| XFLAGS |
SE_INT32_TYPE |
NULL |
A value indicating if the original documents in the XML document table are stored compressed or uncompressed
By default,
documents are compressed. Compressed documents provide better performance. |
This table occurs once in each ArcSDE database. It contains one row for
each XML column that has an XPath index.
| INDEX_ID |
SE_INT32_TYPE |
NOT NULL |
The identifier of the XPath index The table’s primary key, also used to reference SE_XML_INDEX_TAGS
table |
| INDEX_NAME |
SE_STRING_TYPE |
NOT NULL |
The name of the XPath index |
| OWNER |
SE_STRING_TYPE |
NOT NULL |
The database user who owns the XML column
For ArcIMS Metadata Services, this is the user specified in the service’s ArcXML
configuration file. |
| INDEX_TYPE |
SE_INT32_TYPE |
NOT NULL |
A value indicating the type of XPath index
The value will be 2 for the index type SE_XML_INDEX_DEFINITION and 1 for the index type SE_XML_INDEX_TEMPLATE.
For XPath indexes associated with an ArcIMS Metadata Service, only the index type SE_XML_INDEX_DEFINITION
is supported. |
| DESCRIPTION |
SE_STRING_TYPE |
NULL |
Text identifying the XPath index If an
index definition file was used to create the index, the index’s description may
be specified at the top of the file |
The definition of which elements and attributes are included in or excluded
from each XPath index is recorded in this table. This table occurs once
in each ArcSDE database. It contains one row for each XPath associated
with an XML column’s XPath.
| INDEX_ID |
SE_INT32_TYPE |
NOT NULL |
The identifier of the XPath index associated with an XML column, if one exists,
and a foreign key to the XML indexes table |
| TAG_ID |
SE_INT32_TYPE |
NOT NULL |
The identifier of an XPath or tag |
| TAG_NAME |
SE_STRING_TYPE |
NOT NULL |
An absolute XPath identifying an XML
element or attribute that may occur in an XML document |
| DATA_TYPE |
SE_INT32_TYPE |
NOT NULL |
Data type of tag |
| TAG_ALIAS |
SE_INT32_TYPE |
NULL |
A number that may be used to identify an XPath |
| DESCRIPTION |
SE_STRING_TYPE |
NULL |
Text identifying the content that should
be contained in the XML element or attribute |
| IS_EXCLUDED |
SE_INT32_TYPE |
NOT NULL |
A value indicating if the XML element is included in or excluded from the XPath index A zero indicates the XPath is included; a one indicates the
XPath is excluded. |
The ArcSDE database contains one of these tables for each XML column that
has an XPath index. The number in the table name is the XML column’s identifier.
This table contains one row for each XML element or attribute in each
document that is included in the XPath index.
| XML_KEY_COLUMN |
SE_INT32_TYPE |
NOT NULL |
The primary key for the table, Sde_xml_id (SE_INT32_TYPE),
and the XML document’s identifier A foreign key to the XML document table |
| SDE_XML_ID |
SE_INT32_TYPE |
NOT NULL |
The XML document’s identifier and a
foreign key to the XML document table |
| TAG_ID |
SE_INT32_TYPE |
NOT NULL |
The identifier for the XML element or attribute that is indexed This number corresponds to the value in the tag_id
column in the XML index tags table |
| DOUBLE_TAG |
FLOAT |
NULL |
For XPaths that are indexed numerically, the number contained in the element or attribute For ArcIMS Metadata Services, this column is used to respond
to TAGVALUE requests. |
| STRING_TAG |
SE_NSTRING_TYPE |
NULL |
For BTREE indexes |
| TEXT_TAG |
CLOB (Oracle)
NTEXT (SqlServer) |
NULL |
For XML elements or attributes that are indexed as string, the text contained in the element or attribute A text index may
optionally be built on this column and this index is used to respond to XPath queries
or, for ArcIMS Metadata Services, to respond to TAGTEXT
requests. |
| SDE_TIME_STAMP* |
SE_INT32_TYPE |
NOT NULL |
For SQL Server only
This column contains a time stamp that is used to support incremental updates to the text index. |
The ArcSDE database contains one of these tables for each XML column. The
number in the table name is the XML column’s identifier. This table contains
one row for each XML document stored in the XML column.
| SDE_XML_ID |
SE_INT32_TYPE |
NOT NULL |
The identifier for an XML document stored in the XML column
and primary key for the table |
| DOC_PROPERTY |
SE_INT32_TYPE |
NULL |
A value indicating if any conflicts were found when adding the content of an XML document to the XPath index
One indicates a conflict was found; for example, when an element is supposed to
be indexed numerically but the document contains a string in that element
instead
A NULL value indicates there were no problems indexing the document |
| XML_DOC |
BLOB |
NOT NULL |
The actual XML document |
| XML_DOC_VAL |
BLOB |
NULL |
The content
of the entire XML document with all XML tags removed A text index is built on this column by default;
this index is used to respond to full-text queries or, for ArcIMS Metadata
Services, to respond to FULLTEXT requests |
| SDE_TIME_STAMP* |
SE_INT32_TYPE |
NOT NULL |
For SQL Server only
This column contains a time stamp that is used to support incremental updates to
the text index |
