Topic: with SQL requests from Delfi
Such question -
By means of SQL request from Delfi I write down in table ACCESS the data.
After that I fulfill to this table other request on determination of the maximum value of one of columns and I save this value in a variable. It is fulfilled in a cycle and why - that the correct value is appropriated by this variable not always. Periodically, and sometimes and often appears 0. Such sensation that the data has not time to be saved in the table. Tried to increase an interval between record and request about 4 seconds, but result it is not watched. In what there can be a business?
