Set the parameter value from a buffer.
Source position: db.pas line 1456
public procedure TParam.SetData( |
Buffer: Pointer |

Buffer |
|
Buffer to read data from. |
SetData performs the reverse operation of TParam.GetData: it reads the parameter value from the memory area pointed to by Buffer. The size of the data read is determined by TParam.GetDataSize and the type of data by TParam.DataType : it is the same storage mechanism used by TField, and so can be used to copy the value from a TDataset record buffer.
Not all field types are supported. If an unsupported field type is encountered, an EDatabaseError exception is raised.
