| will need either dynamic sql or a lot of if statements.Actually I think you will have to loop through the table and execute each row.Maybe create a function to which you pass the values and return a 1 or 0?==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |

| I don't understand what you are trying to accomplish. You want to pass in a value, and use that value in a comparison statement that is build using the value from the speedOperator in the table, correct?If so, I'm not sure how the data you get is going to be meaningful, as you never really know what you're going to get back. |

| yes..actually my comparison will be against one row..I filter one unit's informationeg. speed = 17then i match it with all records with specified criterias and operatorsand then returns with matched criteriaIt matches like belowselect * from tbl_FilterCriteriawhere @speed [operator] speed[table column name] |
