成员
| 成员名称 | 说明 | |
|---|---|---|
| BUFF_INIT | Specifies that the columns in new buffers of this type are initialized with zeros. | |
| BUFF_NOOLEDB | Specifies that the buffer does not contain status information in its rows. |
注释
The values in this enumeration are provided to the RegisterBufferType method to control how the columns in the registered buffer type are initialized, whether status information is stored for each column in the buffer, and whether the data flow task is notified when the buffer becomes full.
If the BUFF_NOOLEDB value is not set, the memory size of a buffer is reduced because space for column status is not allocated for each column in the buffer. The memory savings equals the size of the status value, times the number of rows in the buffer, times the number of columns in a row.
