Subject Re: TIBOQuery param AsFloat strange behaviour
Author
I did some tests and it seems that IBO is sending the old parameter's buffer value to Firebird. 

For example, if I set the parameter to zero, at the first execution, IBO is sending null.
If before the second execution I set the parameter to 1, IBO is sending "0" (the previous value), and so on...

This is a bug for sure, but I don't think IBOQuery is the right component to run DML statements. For that, IB_DSQL should be used (and it doesn't have this bug).
