the CQL string you specify, getting the tablename appropriately from the POCO Type T.
Declaration
Task DeleteAsync<T>(string cql, params object[] args)
Parameters
Returns
Type Parameters
DeleteAsync<T>(T, CqlQueryOptions)
Deletes the specified POCO from Cassandra.

Parameters
Returns
InsertAsync<T>(T, CqlQueryOptions)
Inserts the specified POCO in Cassandra.
Declaration
Task InsertAsync<T>(T poco, CqlQueryOptions queryOptions = null)
Parameters
Returns
Type Parameters
InsertAsync<T>(T, bool, 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
|
| bool |
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 Parameters
InsertAsync<T>(T, bool, int?, 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
|
| bool |
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.
|
| int? |
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 Parameters
UpdateAsync<T>(Cql)
Updates the table for the poco type specified (T) using the CQL statement specified. Prepends "UPDATE tablename" to the CQL statement you specify,

string you specify, getting the tablename appropriately from the POCO Type T.
Declaration
Task UpdateAsync<T>(string cql, params object[] args)
