Python Script tool

Question

I have written a scripting tool for first time using python where I am filtering the feature set of a feature layer by applying filters on the fields in the attribute table of a feature Layer Also, Providing a feature layer as a parameter and input field having datatype Value Table and to perform filtering on the Feature Layer I need to generate SQL expression for which I need the data Type of particular field .
Is this approach fine or should I implement it in any other way

You can easily create SQL expressions with the SqlExpression parameter type. Just set its dependency to the layer and ArcGIS automatically fills out the possible fields and values.
