This the brief scenario where the results are shown wrong

Select query is used to fetch selected columns from multiple tables, query uses DISTINCT .

Query: SELECT DISTINCT(c.column2), a.column1, c.column3, d.column2, d.column4, c.column4, c.column5 FROM tableA a,tableB b, tableC c, tableD d WHERE a.column2 = b.column2 AND c.column1 = b.column2 AND c.column3 = b.column3 AND c.column2 = d.column3 AND d.column5 = b.column3;

Parallely from another sessions updates are issued on the tables

update tableA set column7=568 where column1='878767888';

In this case , select query is resulting garbage outputs .
