# Projections management
The EventStoreDB Client API includes helper methods that use the HTTP API to allow you to manage projections. This document describes the methods found in the ProjectionsManager class. All methods in this class are asynchronous.
# Enable a projection
Enables an existing projection by name. You must have access to a projection to enable it.
public Task EnableAsync(string name, UserCredentials userCredentials = null)
# Disable a projection
Disables an existing projection by name. You must have access to a projection to disable it.
public Task DisableAsync(string name, UserCredentials userCredentials = null)
# Abort a projection
Aborts an existing projection by name. You must have access to a projection to abort it.
public Task AbortAsync(string name, UserCredentials userCredentials = null)
# Create a one-time projection
Creates a projection that runs until the end of the log and then stops. The query parameter contains the JavaScript you want created as a one time projection.
public Task CreateOneTimeAsync(string query, UserCredentials userCredentials = null)
# Create a continuous projection
Creates a projection that runs until the end of the log and then continues running. The query parameter contains the JavaScript you want created as a one time projection. Continuous projections have explicit names and you can enable or disable them via this name.
public Task CreateContinuousAsync(string name, string query, UserCredentials userCredentials = null)
# List all projections
Returns a list of all projections.
public Task<List<ProjectionDetails>> ListAllAsync(UserCredentials userCredentials = null)
# List one-time projections
Returns a list of all One-Time Projections.
public Task<List<ProjectionDetails>> ListOneTimeAsync(UserCredentials userCredentials = null)
# Get statistics on a projection
Returns the statistics associated with a named projection.
public Task<string> GetStatisticsAsync(string name, UserCredentials userCredentials = null)
# Delete projection
Deletes a named projection. You must have access to a projection to delete it.
public Task DeleteAsync(string name, UserCredentials userCredentials = null)
# Get state
Retrieves the state of a projection.
public Task<string> GetState(string name, UserCredentials userCredentials = null)
# Get partition state
Retrieves the state of the projection via the given partition.
public Task<string> GetPartitionStateAsync(string name, string partition, UserCredentials userCredentials = null)
# Get result
Retrieves the result of the projection.
public Task<string> GetResult(string name, UserCredentials userCredentials = null)
# Get partition result
Retrieves the result of the projection via the given partition.
public Task<string> GetPartitionResultAsync(string name, string partition, UserCredentials userCredentials = null)
