BUG #: 55938 (SQLBUG_70)
The following query gives varying performance depending on the value you use for col6 in the BETWEEN clause:
SELECT T1.col1 ,T1.col2 ,T1.col3FROM Table1 AS T1WHERE EXISTS(SELECT * FROM TABLE1 AS T2WHERE T1.col1 = T2.col1 and T1.col4 = T2.col4 AND(T2.col5 = 801101 OR T2.col5=801102 OR T2.col5=801105 OR T2.col5=803198 ) AND T2.col6 BETWEEN 1 and 10 )
A value lower than the one used in the BETWEEN clause must exist in the table. In the preceding example, col6 in TABLE1 must have a value lower than 1 or it will degrade performance.
Insert a dummy row in the table with a value for col6 that is lower than the one used in the BETWEEN clause.
