Specifies whether an application can call the SQLGetData() function for the previously accessed LOB columns and maintain the data offset position from the previous call to the SQLGetData() function when querying data servers that support Dynamic Data Format.
Note that when the keyword is set to 1 to allow re-access to LOB columns, some resources on the server might not be freed upon completion of SQLGetData().
If the server does not support Dynamic Data Format, this keyword has no effect, and calls to SQLGetData() for previously accessed LOB columns are allowed.
A similar keyword exists called AllowGetDataLOBReaccess that allows applications to call SQLGetData() for previously accessed LOB columns. However, if the AllowGetDataLOBReaccess keyword is used, data position and offset information is not maintained. When the LOB column is re-accessed after interleaving, SQLGetData() starts reading data from the beginning for that LOB data column. If both AllowGetDataLOBReaccess and AllowInterleavedGetData are set for a given connection or statement, the AllowInterleavedGetData setting takes precedence over AllowGetDataLOBReaccess.
