Data Integration with Sybase Avaki Studio 145
Input Source
To edit the expressions, click in the Value column to make it editable. Type your map-
ping expression directly in the table cell, or click the “…” button to open the Edit
Expression dialog if you need more room than the table cell provides. Right click
(either in the table cell directly, or in the Edit Expression dialog) to show a con-
text-sensitive menu of column names, variables, and functions that you can paste into
the Expression field. For details on using JavaScript expressions, see “Using expres-
sions within Avaki Studio” on page 66. For details on the context menu, see “The
expressions menu” on page 71.
Arrays. If a given parameter is an array, when you click in the Value column, the
Array Parameter Values dialog appears.
You can enter an expression that evaluates to an array of the same type using the Java-
Script Expression tab. For example, your model might already have a parameter
that’s an array of the right type, which you want to map directly to the input source
parameter.
Alternatively, you can enter an array of individual expressions using the Array tab.
• Click the Add button to add a new element to the array.
• Click the Remove button next to any element to remove it.
• Edit the expression next to any element in the array. Remember that string con-
stants must be surrounded by quotation marks.
