unionM,N: The row refers to the union of the rows with id values of M and N. derivedN: The row refers to the derived table result for the row with an id value of N. A derived table may result, for example, from a subquery in the FROM clause. subqueryN: The row refers to the...
A default PLAN_TABLE exists for every user without the need to create it beforehand. Using the DBMS_XPLAN.DISPLAY_CURSOR Function Alternatively the execution plan for an executed SQL statement can be generated and displayed by using the DBMS_XPLAN.DISPLAY_CURSOR function. The following example ...
DFEApply – Executes the function specified by functor in the arguments section, on the value stored in the specified variable DFEAlgoWriteProperty – Explain operator for the property-writing portion of mutate algorithm invocations. DFEBFSAlgo – Explain operator for invocations of the Breadth First...
MySQL was ableto do a LEFT JOIN optimization on the query and does not examine more rows inthis table for the previous row combination after it finds one row that matchesthe LEFT JOIN criteria. Here is an example of the type of query that can beoptimized this way: SELECT * FROM t1 LEF...

Keys such as the join key or group by key that are involved in expressions: If you use a CAST function to convert data types, the local join feature is not used. In this case, redistribution occurs. Examples: Example 1: Join two tables. The distribution key is invalid and redistribution...
There is another problem with local variables. When you leave the function where they are declared, their values disappear! You cannot permanently store a value in a local variable. For example, consider the following incorrect code: function SetSpeed(NewValue) ...
In a non-restrictive database, EXECUTE privilege is granted to PUBLIC when the function is automatically created. Information returned The data type of the result is CLOB(50M). Example SELECT EXPLAIN_FORMAT_STATS(SNAPSHOT) FROM EXPLAIN_STATEMENT WHERE EXPLAIN_REQUESTER = 'DB2USER1' AND EXPLAIN_...
When the rows to be read can be read during the optimization phase (for example, by reading index rows), there is no need to read any tables during query execution. The first condition is fulfilled when the query is implicitly grouped (contains an aggregate function but no GROUP BY ...
Again, when a logged-in user has provided case specific phenotype information (see A), they are shown a gene-to-phenotype rank (according to CADA ranking), in our example rank for a variant in PAX9. (D) Semi-automated ACMG classification of our structural variant based on AutoCNV (see ...
