union all fails

  • i have three tables all with the same structure, if i query two tables and do a union between them everything is fine, if i query three tables with a union between each then the data changes, i have a field that is a unique number, when i look at the results of the three way query it has used the first value found for subsequent rows

  • apologies, being a complete arse, my subquery was completly wrong and was duplicating results

    but that still did not explain why the field data changed ?

  • note if any fiels in any table is changed (even if you put only space in it), the whole record of the table containing this field is appeared in Union query..

    please read again carefully about union query
