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.
