Parameters

Type	Name	Description
Cql	cql

Type Parameters

Name	Description
T

Delete<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

void Delete<T>(string cql, params object[] args)

Parameters

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

Type Parameters

Name	Description
T

Execute(Cql)

Executes the arbitrary CQL statement specified.

Declaration

void Execute(Cql cql)

Parameters

Type	Name	Description
Cql	cql

Execute(String, Object[])

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

Declaration

void Execute(string cql, params object[] args)

Parameters

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

Insert<T>(T, CqlQueryOptions)

Inserts the specified POCO in Cassandra.

Declaration

void Insert<T>(T poco, CqlQueryOptions queryOptions = null)

Parameters

Type	Name	Description
T	poco
CqlQueryOptions	queryOptions

Type Parameters

Name	Description
T

Insert<T>(T, Boolean, CqlQueryOptions)

Inserts the specified POCO in Cassandra.

Declaration

void Insert<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

Type Parameters

Name	Description
T

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

Inserts the specified POCO in Cassandra.

Declaration

void Insert<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

Type Parameters

Name	Description
T

Update<T>(T, CqlQueryOptions)

Updates the POCO specified in Cassandra.
