Wouldn't be a good idea to delay call of openCursor() till the first fetch in ISC API emulation layer?
If your provider is supposed to be used only for embedded connections - yep, you can do it. Remote layer does not support this format change since at least arrival of batch records transfer.
If this is a limitation of remote provider then it is remote provider who must throw the error.
So, ability to call isc_dsql_fetch() with different SQLDA is broken in FB4, right? -- WBR, SD. Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
