Returns

Type	Description
System.Threading.Tasks.Task

Type Parameters

Name	Description
T

DeleteAsync<T>(String, Object[])

Deletes from the table for the POCO type specified (T) using the CQL string and bind variable values specified. Prepends "DELETE FROM tablname " to the CQL string you specify, getting the tablename appropriately from the POCO Type T.

Declaration

Task DeleteAsync<T>(string cql, params object[] args)

Parameters

Type	Name	Description
System.String	cql
System.Object[]	args

Returns

Type	Description
System.Threading.Tasks.Task

Returns

Type	Description
System.Threading.Tasks.Task

ExecuteAsync(String, Object[])

Executes an arbitrary CQL string with the bind variable values specified.

Declaration

InsertAsync<T>(T, CqlQueryOptions)

Inserts the specified POCO in Cassandra.

Declaration

Task InsertAsync<T>(T poco, CqlQueryOptions queryOptions = null)

Parameters

Type	Name	Description
T	poco
CqlQueryOptions	queryOptions

Returns

Type	Description
System.Threading.Tasks.Task

Type Parameters

Name	Description
T

InsertAsync<T>(T, Boolean, CqlQueryOptions)

Inserts the specified POCO in Cassandra.

Declaration

Task InsertAsync<T>(T poco, bool insertNulls, CqlQueryOptions queryOptions = null)

Parameters

Type	Name	Description
T	poco	The POCO instance
System.Boolean	insertNulls	Determines if the query must be generated using NULL values for null POCO members. Use false if you don't want to consider null values for the INSERT operation (recommended). Use true if you want to override all the values in the table, generating tombstones for null values.
CqlQueryOptions	queryOptions	Optional query options

Returns

Type	Description
System.Threading.Tasks.Task

Type Parameters

Name	Description
T

InsertAsync<T>(T, Boolean, Nullable<Int32>, CqlQueryOptions)

Inserts the specified POCO in Cassandra.

Declaration

Task InsertAsync<T>(T poco, bool insertNulls, int? ttl, CqlQueryOptions queryOptions = null)

Parameters

Type	Name	Description
T	poco	The POCO instance
System.Boolean	insertNulls	Determines if the query must be generated using NULL values for null POCO members. Use false if you don't want to consider null values for the INSERT operation (recommended). Use true if you want to override all the values in the table, generating tombstones for null values.
System.Nullable<System.Int32>	ttl	Time to live (in seconds) for the inserted values. If set, the inserted values are automatically removed from the database after the specified time.
CqlQueryOptions	queryOptions	Optional query options

Returns

Type	Description
System.Threading.Tasks.Task

Type Parameters

Name	Description
T

UpdateAsync<T>(T, CqlQueryOptions)
