Constructors

Table(ISession, MappingConfiguration, string, string)

Creates a new instance of the Linq IQueryProvider that represents a table in Cassandra using the mapping configuration provided.

Use this constructor if you want to use a different table and keyspace names than the ones defined in the mapping configuration.

Fluent configuration or attributes can be used to define mapping information.

Declaration
public Table(ISession session, MappingConfiguration config, string tableName, string keyspaceName)
Parameters
Type Name Description
ISession session

Session instance to be used to execute the statements
MappingConfiguration config

Mapping configuration
string tableName

Name of the table
string keyspaceName

Name of the keyspace were the table was created.
Remarks

In case no mapping information is defined, case-insensitive class and method names will be used.

Table(ISession, MappingConfiguration, string)

Use this constructor if you want to use a different table name than the one defined in the mapping configuration.

Fluent configuration or attributes can be used to define mapping information.

Declaration
public Table(ISession session, MappingConfiguration config, string tableName)
Parameters
Type Name Description
ISession session

Session instance to be used to execute the statements
MappingConfiguration config

Mapping configuration
string tableName

Name of the table
Remarks

In case no mapping information is defined, case-insensitive class and method names will be used.

Table(ISession, MappingConfiguration)

Table(ISession)

Creates a new instance of the Linq IQueryProvider that represents a table in Cassandra using Global configuration.

Declaration
public Table(ISession session)
Parameters
Type Name Description
ISession session

Session instance to be used to execute the statements

Properties

Insert(TEntity, bool)

Returns a new CqlInsert<TEntity> command. Use Execute() method to execute the query.

Declaration
public CqlInsert<TEntity> Insert(TEntity entity, bool insertNulls)
Parameters
Type Name Description
TEntity entity

The entity to insert
bool insertNulls
