SQL Profile Recommendations

During SQL tuning, you select a statement for automatic tuning and run SQL Tuning Advisor. The database can profile the following types of statement:

DML statements (

SELECT

,

INSERT

with a

SELECT

clause,

UPDATE

, and

DELETE

)

CREATE

TABLE

statements (only with the

AS

SELECT

clause)

MERGE

statements (the update or insert operations)

SQL Tuning Advisor invokes Automatic Tuning Optimizer to generate recommendations. Recommendations to accept SQL profiles occur in a finding.
