CHAPTER 11 TASKBUILDER SUB-WINDOWS 123
Database Conversion Sub-window Elements
Figure 11.1 shows the Database Conversion sub-window with the following component
elements:
Source/Destination Database – ese drop-down lists allow you to choose the indi-
vidual database located on the target server machine. Because of the connection lag, it
may take a few seconds for the sub-window to update. Some databases, such as Access
and Oracle, will display only one option.
Source/Destination Table – Aer choosing a database, these drop-down lists will be
lled with every table within the database; choose a source and destination table for the
mapping. Because of the connection lag, it may take a few seconds for the sub-window
to update.
Source/Destination Columns – Aer choosing a table, these list boxes will automati-
cally ll with all of the columns in the selected table. e icon on the le of the name
will mark the column as a primary key column or a normal data column; on the right
of the name is the column data type. e column data type is important for assess-
ing type compatibility from source to destination. e data type designations can be
toggled by the Show Data Types check box at the top of the sub-window.
Mapping Diagram – e mapping diagram area is located between the source and des-
tination column lists. e colored lines represent the connections between columns
and will be drawn automatically when mappings are created.
Mappings List – Once column-to-column mappings are made, you can select and de-
lete them from this list when desired. e colors of the mappings in the list correspond
to the color mapping lines on the mapping diagram.
Delete Button – e Delete button is used to delete a selected mapping from the map-
ping list.
Clear All Button – e Clear All button deletes all mappings from the mapping list.
Accept Button – e Accept button saves the current mappings and closes the sub-
window. If there are destination columns that do not currently have a mapping, the
Default Value sub-window (discussed later in this section) will open and allow you to
select default values for those columns.
Cancel Button – e Cancel button closes the sub-window without saving any changes
to the mappings.
Key/Auto Columns –e Key and Auto columns will be present only if the destination
database is a Sybase or Oracle database. It is necessary to mark primary key and auto-
increment columns.
Creating a Mapping
e following are the two methods for creating a mapping between a source and destination
column:
Select the desired column from both column lists and click the Add button.
