Hi, can any one tell me when we need to use recompile option in Stored proc ?
How can we figure out it ?
Is execution plan show any sign that SP needs recompilation?

When the query(s) have no single optimal plan. One example is when you have severe parameter sniffing, data skew or similar.

There is no hard and fast formula as in "You MUST use it here, you MAY NOT use it there." It's a case by case basis.

However, one general rule you could apply, if the procedure builds dynamic TSQL statements, then it might benefit from the recompile option.
