>>Hi!
>>Have a problem with primary ID field in a table. I shall be glad if you will help.
>>
>>Legend:
>>VFP 5.0, Win2000 and about 10 very active users.
>>
>>We have a table with primary key on ID field N(13,0).
>>The table is consist of 400`000 records. Every day users add 5000 new rows in this table.
>>
>>Every day (!!!) programmer find 2-5 broken ID value (only in ID field).
>>Good ID value looks like 3010000001234.
>>Broken ID value looks like |010000001234 or 3|10000001234 (character symbol in first or second position in NUMERIC field). VFP understand this bad ID as 0 and 3. And it means that every day programmer find in the table _several_ rows with the same ID=0 (or ID=3) – the purpose of primary key is not work. Transaction mechanism was not help.
>>
>>The main trouble is: except this work place there are 16 similar sites with 2-5 users and 1-2 broken ID for a week (…and without local support).
>>
>>Need idea!
>>Thank you!
