Go to the MapViewer home page, click on the demos link, then choose the jview.jsp demo. This is a simple utility that you can use to quickly view any spatial data stored in the database or created through Oracle Spatial's functions (such as the result of an sdo_buffer operation). In the jview.jsp page, fill in a datasource name that you already defined, and then simply type a SQL query that will select the table's geometries in the text area named "query 1".

No, but it can use map images from a Webmap Server. MapViewer 10.1.2 supports a new theme type called WMS-Theme, which can be used to import a map layer generated by any 3rd party's OGC WMS 1.1 compliant server. Here is a sample XML map request for MapViewer that includes a WMS theme. Note you can also add WMS themes through the Java API. Note the parameters specified in the WMS theme are for illustration only. <?xml version="1.

Prior to version 10.1.2, all the spatial data rendered by MapViewer had to be in the same spatial reference system (SRS). If your data comes from different sources and they use different SRS's, you had to explicitly use Oracle Spatial's coordinate system functions to transform them into a single reference system for viewing purposes. Starting with 10.1.2, MapViewer can now perform on-the-fly projection of your spatial data. To enable this, you must specify a master srid in your map request.

Yes, support for Oracle workspace manager (WM) is added in MapViewer 10.1.2. For any theme (predefined or dynamic) whose base table is version enabled, you can view its latest modifications in any workspace (and save point within that workspace) by specifying the workspace name (and optionally the savepoint) for the theme. For instance, here is a map request with a dynamic theme that shows the spatial data in a workspace named "ws_1". <map_request ..

Data used with geographic information technology have different characteristics than data required in conventional data base systems. GIS uses spatial data which, quite simply, includes anything that takes up geographic space or has geographic distribution.

The most common cause is the use of double-quotes around table or column names during table creation. When double-quotes are used, table and column names (called identifiers) are stored case-sensitive, meaning you must use double-quotes when referencing the names in a query. Some interfaces, like pgAdmin, automatically double-quote identifiers during table creation. So, for identifiers to be recognized, you must either:

DROP COLUMN functionality was added in release 7.3 with ALTER TABLE DROP COLUMN. In earlier versions, you can do this: BEGIN; LOCK TABLE old_table; SELECT ..

This is basically an excel file, which is stored in the folder of the test created, its name is Default.xls by default.

It is important to note that in order for the data in a Grid to show correct information when using a Filter or when connected to an ODBC source (such as Access) that you set the Index Order for the Table. Otherwise, as you edit data or move around the Grid, the data seem to 'change' (though it doesn't actually change in the Table).

Prepend "[ </a> ]" to the column formula for the first column. This will deactivate the hyperlink to the document. You can then reference the current document in any other column using the Domino syntax and @DocumentUniqueID as the document hyperlink.

Yes. Modify the geometry storage parameter for the defaults keyword of your dbtune.sde file to be SDO_GEOMETRY. For more information on setting up the dbtune.sde file and setting parameters for each of the geometry storage types, refer to the ArcSDE Configuration and Tuning Guide for Oracle (config_tuning_guide_oracle.pdf located in the documentation folder of your install location).

Geo-spatial data is a term used to cover any data with geographic references, for example, Ordnance Survey national grid references, postal addresses, place names or the names of administrative areas.

Oracle database version 8i (8.1.6) or later, as well as Oracle Application Server 9i (9.0.2) or later. It's also possible to simply install a standalone version of Oracle Container for J2EE (OC4J) and deploy MapViewer to it.

A collection of 19 FAQs on working with database objects in PL/SQL. Clear answers are provided with tutorial exercises on defining, opening, and closing cursors, looping through cursors, defining and using cursor variables.

Let's suppose you have two tables: Customers (case table), Purchases (transaction table). Then, the following steps will create a mining model with a nested table column you want: When you're asked to select case table, check "A single table contains the data" and go ahead to select "Customers" as the case table Select a column as the key of the nest table column. Note that this column is not the key of "Purchases", but the key of the rows that belong to the same customer.

The NJEDL's partnership with the NJDEP requires that spatial (GIS) data is cataloged on the NJ Spatial Data Clearinghouse, which was designed in coordination with the Federal Geographic Data Committee (FGDC). This is intended to provide a clearinghouse for spatial data, or GIS compatible data. A data set is considered to be "spatial" if it has spatial coordinates, such as latitude and longitude, or an x,y Cartesian coordinate system.

We do not support ALTER TABLE DROP COLUMN, but do this: SELECT ... -- select all columns but the one you want to remove INTO TABLE new_table FROM old_table; DROP TABLE old_table; ALTER TABLE new_table RENAME TO old_table;
