You can use Visual Explain to
view explained SQL statements as
a graph. You can use the information available from the graph to tune
your
SQL queries for better performance. The nodes in the graph represent
tables
and indexes and each operation on them. The links between the nodes
represent
the flow of data.
Before you begin
In the SQL Query
Builder, Visual Explain is only supported for a single
DML statement.
