Advanced Cursor Options dialog
• Close Query field: Enter any tag; when the value of the tag changes, the cursor releases the result set.
• Previous field: Enter any tag; when the value of the tag changes, the cursor moves to the previous row
of the result set and copies those values to the tag configured in the worksheet body.
• Total number of rows field: Enter a numeric tag that will receive the total number of rows in the result
set.
• Current row number field: Enter a numeric tag that will receive the number of the current row (i.e., the
position of the cursor). When a result set is first opened using the Select trigger, this number is 1.
Each Next trigger increments this number, and each Previous trigger decrements it.
• Table Triggers area…
• Insert field: Enter any tag; when the value of the tag changes, a new row is inserted with the current
values of the tags configured in the worksheet body.
• Update field: Enter any tag; when the value of the tag changes, all rows of the result set are overwritten
with the current values of the tags configured in the worksheet body.
• Delete field: Enter any tag; when the value of the tag changes, all rows of the result set are deleted.
Worksheet Body
Note: Table triggers are available only when Type is set to Table, because these operations work on
the entire table row.
In the body of the worksheet, you can map project tags to the columns (fields) of the result set. For each row
of the body, enter a Tag Name and its corresponding Column. Which columns are available depends on how the
result set is selected, and how it is selected may change during runtime, so be sure to map all necessary
columns.
