- 1.0 Database Access Support Matrix
-
-
- Database Access Version 1.1 lets you use SDE data in ArcView GIS Version 3.1.
- Because ArcView GIS, Database Access, and SDE are developed on
- different schedules, it is important to maintain a record
- of which ArcView GIS version Database Access works with, and which
- SDE servers are supported. The matrix below illustrates
- which versions of these products you can use together.

- 2.0 Database Access Documentation
-
-
- The Database Access documentation is a file in Portable
- Document Format (PDF). After the Database Access Extension
- has been installed, the documentation file, dbaccess.pdf,
- will be located in the av_gis30\avdocs installation directory.
- To view and print PDF files, you will need to install the
- Acrobat Reader from Adobe. For your convenience, we have provided
- an installation of the Adobe Acrobat Reader located in the
- <CD-ROM>:\acrobat3 directory.
-
- You can also obtain the Acrobat Reader from Adobe's home
- page at www.adobe.com.

-
- 3.0 Setting Up Your Machine
-
-
- If you are new to using SDE data in ArcView GIS, you can
- find out how to set up your computer by referring to the
- on-line help for the Database Access extension. Double-click the
- Extensions book in the contents page, then the Database Access
- book. The Using the Spatial Database Engine (SDE) book
- contains topics for setting up your computer.
-
-
- 4.0 Sample extensions and Scripts
-
-
- This extension includes several sample extensions and scripts.
- For more information on these samples, double-click
- the Extensions book in the Help Contents page, then the Database
- Access book and refer to the Sample scripts and
- extensions book. Additional scripts, referenced by the Avenue
- request help, can be located by typing "database access"
- in the on-line help's Index. Select Avenue examples under
- the Database Access extension heading, then click Display.
-
- 5.0 Issues and Limitations
-
-
- For a list of known limits for this extension, double-click
- the Extensions book in the contents page, then the Database
- Access book. The "Known issues" help topic is located under the
- Troubleshooting book.
-
- The following known issues are not listed in the "Known issues" help
- topic:
-
- 1) ArcView GIS Version 3.0a projects that used the Database Themes
- extension will have problems when opened in ArcView GIS Version 3.1.
- The extension has been replaced by Database Access version 1.1 in
- core ArcView GIS. The following steps will resolve this conflict:
-
- 1. Open the project in ArcView GIS Version 3.1.
- 2. Use the Customize dialog to delete the "Add Database Theme" and
- "Export to Table" controls from the View GUI.
- 3. Delete all database themes from the project. (Scripts using
- Database Themes objects won't work.)
- 4. Load the Database Access extension, then recreate the database themes.
- 5. Rewrite any scripts.
-
- Note: Database Access requires that you use an SDE version 3.x server.
-
- 2) The DBTheme.BlinkRecord request does not work when
- the database theme has a unique value or graduated color legend.
- Because of this problem, features in the classified theme won't
- flash in some circumstances if you double-click on a feature in
- the left panel of the Identify window.
-
- 3) If you have a database theme that has a join and in theme
- properties, you replace the join statement with another where clause,
- you will lose the connection and get an error when you attempt to draw
- the theme. If this happens, you can delete the old database theme,
- create a new connection and then re-create the database theme.
-
- 4) If you have a database table with a blob field, each blob file is
- created twice when the project is opened.
-
-
- 6.0 Known Issues specific to SDE for Coverages
-
-
- 1) When opening a Map Librarian DBThemeÆs table in ArcView GIS, the table
- may appear with no records or attributes. To rectify this problem,
- remove all open DBTables and then open the Map Librarian DBTheme's
- table.
-
- 2) If you apply more than 2 spatial filters to a querydef in ArcView GIS,
- the first 2 filters will be applied and the rest will be ignored.
-
- 3) In ArcView GIS, you cannot select features from multiple SDE for
- Coverages Database Themes at once. Each themeÆs features must be
- selected separately.
-
- 4) In ArcView GIS, large number values may appear incorrectly in Database
- Tables. For example, the number 1565523000 may appear as 11000000. This
- is only a Database Table display problem so if you use the Identify tool
- or a recordset to get the number, the proper value will be returned.
-
- 5) When using the ArcView GIS legend editor on SDE for Coverages layers the
- UNIQUE, NATURAL BREAKS and QUANTILE classifications will cause ArcView GIS
- to hang until killed.
-
- 6) All features in layers registered from Shapefiles will flash when the
- feature is clicked in the Identify window in ArcView GIS.
-
- 7) If you export a registered Shapefile layer from SDE for Coverages
- using ArcView GIS, the exported fields may appear blank or contain all zeros.
-
- 8) In ArcView GIS, if you make a graduated color classification using a
- non-integer number field, the next graduated color classification you make
- using an integer field will fail. Also, if you make a graduated color
- classification using an integer field and then try to make one using a
- non-integer number field, the second classification will fail.
-
- 9) You cannot apply more than 2 spatial filters to a querydef using SDE
- for Coverages. If you apply more than 2 spatial filters, only the first
- 2 are applied.
-
- 10) Parentheses are ignored when where clauses are evaluated. This may
- cause unexpected results if you use parentheses in the query builder to
- select features or when you define a where clause for a Database Theme.
-
- 11) When creating a Database Table from a Shapefile in SDE for Coverages,
- the Shape field is ignored if it is included in the select statement. The
- Shape field is also ignored if you use the SetSql request on a querydef
- and then open a recordset.
