This execution plan shows the SQL optimizers query execution path. This is a feature of the database, not SQL Developer. Oracle prepares and compiles an execution plan for all of the DML statements executed. But you can check the estimated execution time. The database is called Oracle, but it isnt able to predict the future. What you DON’T have to do now, is look up the SQL_ID or write the SELECT statement from scratch anymore.Īlso, we don’t run that query for you automatically – you need to decide if you want to get the results in a GRID (F9) or as unformatted text (F5). Getting exact execution time without actual execution, that just wont happen. If you want to change up the options to the call, you just need to amend the query. Put your cursor on the query, click on the drop-down arrow on the Explain Plan button. We’ve made it VERY EASY to get those DBMS_XPLANs the old-fashioned way – we generate the call for you. ![]() But maybe you just want to always run DBMS_XPLAN. Query execution is performed in the processing layer. ![]() Now, SQL Developer has for a few releases made it easy to SEE what those SQL_IDs are for your queries… Note the drop-down control added to the Explain Plan button in the worksheet toolbar.Ĭlicking that hyperlinked text, we’d go get the plan for you and feed it to OUR plan viewer. Instead, Snowflake combines a completely new SQL query engine with an innovative architecture. The not-fun part, is going from a SQL statement to the SQL_ID. There is even a nice set of views that contain everything we need to know about our SQL and their exectution plans.Īnd, we have a really cool PL/SQL package, DBMS_XPLAN for generating reports on our troublesome queries. The database gives us MANY things to help with this.
