Edit online

Table Explorer View

Relational databases tables in the Data Source Explorer view can be displayed and edited in the Table Explorer view by selecting the Edit action from the contextual menu of a Table node or by double-clicking one of its fields. To modify the content of a cell, double-click it and start typing. When editing is complete, Oxygen XML Author attempts to update the database with the new cell content.

Figure 1. Table Explorer View

You can sort the content of a table by one of its columns by clicking its column header.

Note the following:

  • The first column is an index (not part of the table structure).
  • Every column header contains the field name and its data type.
  • The primary key columns are marked with this symbol: .
  • Multiple tables are presented in a tabbed manner.

For performance issues, you can set the maximum number of cells that are displayed in the Table Explorer view (using the Limit the number of cells option in the Data Sources Preferences page). If a table that has more cells than the value set in the options is displayed in the Table Explorer view, a warning dialog box informs you that the table is only partially shown.

You are notified if the value you have entered in a cell is not valid (and thus cannot be updated).

  • If the content of the edited cell does not belong to the data type of the column, the cell is marked by a red square and remains in an editing state until a correct value is inserted. For example, in the following figure propID contains LONG values. If a character or string is inserted, the cell will look like this:

  • If the constraints of the database are not met (for instance, primary key constraints), an information dialog box will appear, notifying you of the reason the database has not been updated. For example, in the table below, trying to set the second record in the primary key propID column to 8, results in a duplicate entry error since that value has already been used in the first record:
