public virtual size_t GetPlan(char * dst, size_t dstSize)

The number of bytes copied to the buffer; otherwise, if the dst value is NULL, returns the number of bytes required to store the plan, excluding the null-terminator.

This method is intended primarily for use during development.

An empty string is returned if there is no plan. Plans exist when the prepared statement is a SQL query.

When the plan is obtained before the associated query has been executed, the plan shows the operations used to execute the query. The plan additionally shows the number of rows each operation produced when the plan is obtained after the query has been executed. This plan can be used to gain insight about the execution of the query.
