## Code Examples

```python title="Example - Clear Named Query Cache for a Specific Project"
# Calling this simply clears all Named Query caches.
# This example is being called from the shared scope. If called from the project scope, the projectName parameter should be omitted.
 
 
projectName = "myProject"
namedQueryPath = "folder/selectFromInventory"
 
system.db.clearNamedQueryCache(projectName, namedQueryPath)
```

```python title="Example - Clear Named Query Cache"
# If the same Named Query is called multiple times with different parameters in a single script, then we can clear the caches once we're done with the following.
# This example assumes the script is running in the project scope. If called from the Shared Scope, the name of the project would need to be included.
 
namedQueryPath = "myUpdateQuery"
 
# This creates one cache.
params = {"param1":"A"}
system.db.runNamedQuery(namedQueryPath, params)
 
# This creates a separate cache.
params = {"param1":"B"}
system.db.runNamedQuery(namedQueryPath, params)
 
# Clear all of the caches from the specified Named Query. Note that all caches are cleared, including those generated from elsewhere on the Gateway.
system.db.clearNamedQueryCache(namedQueryPath)
