The following table describes the workflow parameter data type conversion that the Data Integration Service performs:

To convert a string to an integer, the string must contain a number.

To convert a string to a boolean, the string must contain either "true" or "false."

For example, a Mapping task has a High Precision property with a boolean data type. You need to assign a workflow parameter to the property. You can define the workflow parameter as a string with a default value of "true" or "false". When you run the workflow, the Data Integration Service converts the parameter value to the boolean value.

You cannot assign a connection parameter to a parameter that is not a connection parameter.
