OLE DB Property of Rowset and Command — «force_param_describe»
This property is now obsolete. Was removed in the third version (v3.20).
This property is now obsolete. Starting from version 3.15, IBProvider always obtains the parameter descriptions from server.
Implicit obtaining of parameters descriptions and using of it for transfer parameters values with that types which database server hopes to get. In this mode they may, for example, not to make any difference for parameters for usual string and BLOB (adChar, adVarChar, adLongVarChar) fields — provider will make all necessary conversions.
Pay your attention to the fact that «Client Cursor Engine» can interpret long strings (e.g. VARCHAR(32000)) as BLOB-field and work with it with incorrect method.
The overheads are one access a server when executing the command first time. If you work with IBProvider through ADODB without using of «Client Cursor Engine» and exactly define parameters types than it should be better to set it in False.
