TDengineDriver Namespace

this class used to get an instance of struct of TAO_BIND or TAOS_MULTI_BIND And the instance is corresponding with TDengine data type. For example, calling "bindBinary" will return a TAOS_BIND object that is corresponding with TDengine's binary type.

Using to bind different columns types in multiple rows.

Defined this Driver's mainly APIs

TDengine's meta info.

TAOS_BIND struct, used to hold a parameter(one value) while using "stmt insert".

TAOS_MULTI_BINDstruct,used to hold a multiple values while using "stmt bind".

User defined callback function for interface FetchRowAsync(IntPtr, FetchRowAsyncCallback, IntPtr),actually is a delegate in .Net. This callback allow applications to get each row of the batch records by calling FetchRowAsync(IntPtr, FetchRowAsyncCallback, IntPtr) forward iteration.After reading all the records in a block, the application needs to continue calling FetchRowAsync(IntPtr, FetchRowAsyncCallback, IntPtr) in this callback function to obtain the next batch of records for processing until the number of records is zero.

User defined callback function for interface QueryAsync(IntPtr, String, QueryAsyncCallback, IntPtr),actually is a delegate in .Net. This function aim to handle the taoRes which points to the caller method's SQL result set.

In asynchronous subscribe mode, the prototype of the callback function.

The enum indicate the data types and their code that TDengine supports.

Options that can be set before get TDegnine connection. Can set like locale,char-set,timezone,taos.cfg Dir and connection active time.

Precision string of the timestamps in the text data while using schemaless insert.

This enum is used to indicate different TDengine's different schemaless protocol.
