Runs a named query and returns the results. Note that the number of parameters in the function is determined by scope. Both versions of the function are listed below.
This scripting function has no Client Permission restrictions.
system.db.runNamedQuery(path, parameters, [tx], [getKey])
String path - The path to the named query to run. Note that this is the full path to the query, including any folders.
PyDictionary parameters - A Python dictionary of parameters for the named query to use.
String tx - An optional transaction ID, obtained from beginNamedQueryTransaction. If blank, will not be part of a transaction.
Boolean getKey - Optional. Only used for Update Query types. A flag indicating whether or not the result should be the number of rows affected (getKey=0) or the newly generated key value that was created as a result of the update (getKey=1). Not all databases support automatic retrieval of generated keys.
Object - The results of the query. The exact object returned depends on the Query Type property of the Named Query: typically either a dataset when set to Query, an integer representing the number of rows affected when set to Update Query, or an object matching the datatype of the value returned by a Scalar Query.

system.db.runNamedQuery(project, path, parameters, [tx], [getKey])
String project - The project name the query exists in.

Gateway
# This example will run a Named Query without any parameters in the Project scope.
# The second argument in the function is NOT optional, so named queries that do not require a parameter must still pass an empty dictionary as an argument.
# Request the Named Query with an empty dictionary as the second parameter.
system.db.runNamedQuery("folderName/myNamedQuery", {})
# This example will run a Named Query without any parameters in the Gateway scope.
# The last argument in the function is NOT optional, so named queries that do not require a parameter must still pass an empty dictionary as an argument.
# Request the Named Query to execute.
system.db.runNamedQuery("ProjectName", "folderName/myNamedQuery", {})
# This example will run a Named Query while passing some parameters in the Project scope.
# The Named Query is assumed to have two parameters already defined on the Named Query:
# param1 : A string
# param2 : An integer
# Create a python dictionary of parameters to pass
params = {"param1":"my string", "param2":10}
# Run the Named Query
system.db.runNamedQuery("myUpdateQuery", params)
