dataset Tag

Dataset tag is a command tag. It defines a data set which stores rows of data to be retrieved later by other command tags.

The syntax is:

  <dataset autorewind="true/false" id="datasetid" mode="replace/append">

There are two ways to populate the data set with rows of data.

• sql - use sql tag to declare the sql statement to be used to retrieve the data from jdbc data source to populate this data set.
• rowdata tag - use rowdata tag to manually populate one row of data into this data set.

The autorewind attribute is used to automatically start at the first row when all rows have been retrieved.

The mode attribute is used to append the new data to the data set or to clear the old data and replace them with the new data.

Use getData(...) (system method in mScript method) to retrieve data row/field from the dataset.
