UniQuery.Params.ValueCount

[FredS]

Hi,
While attempting to lessen the performance hit reported in Bulk Inserts I ran into an issue.

Setting:

Code: Select all

UniQuery.Params.ValueCount := 2; 

after it was 1 essentially makes existing data at index 0 unavailable.

The described behavior is correct. On modifying the UniQuery.Params.ValueCount property, you will lose access to previously created elements.

The described behavior is correct. On modifying the UniQuery.Params.ValueCount property, you will lose access to previously created elements.

That setter method calls RedimItems which calls VarArrayRedim on any other change which preserves prior data.
So from 2..200k existing data is retained.

We will consider the possibility to change behavior of UniDAC in the studied case. We will inform you about the results shortly.

Thank you for the information. We have reproduced the problem and fixed the bug. The fix will be included in the next UniDAC build.
