If a procedural object, such as a stored PL/SQL function or a view, becomes invalid, the DBA does not necessarily have to do anything: the first time it is accessed, Oracle will attempt to recompile it and this may well succeed But if an index becomes unusable for any reason, it must always be repaired explicitly before it can be used An index consists of the index key values, sorted into order, each with the relevant rowid The rowid is the physical pointer to the location of the row to which the index key refers If the rowids of the table are changed, then the index will be marked as unusable This could occur for a number of reasons Perhaps the most common is that the table has been moved, with the ALTER TABLE MOVE command This will change the physical placement of all the rows, and therefore the index entries will be pointing to the wrong place Oracle will be aware of this and will therefore not permit use of the index In earlier releases of the Oracle database, it was more than likely that users would detect unusable indexes because their sessions would return errors When executing SQL statements, if the session attempted to use an unusable index, it would immediately return an error, and the statement would fail From release 10g and higher the database changes this behavior If a statement attempts to use an unusable index, the statement will revert to an execution plan that does not require the index Thus, statements will always succeed but perhaps at greatly reduced performance This behavior is controlled by the instance parameter SKIP_UNUSABLE_INDEXES, which defaults to TRUE The exception to this is if the index is necessary to enforce a constraint: if the index on a primary key column becomes unusable, the table will be locked for DML TIP If you wish your database to react as earlier releases, where unusable indexes would cause errors, issue the command ALTER SYSTEM SET SKIP_ UNUSABLE_INDEXES=FALSE; To detect indexes that have become unusable, query the DBA_INDEXES view:. qr code excel 2010 Generating QR Code barcodes from cells in Excel using VBA and ...

Download Free Trial Package | Users Tutorial included. of the table, in order to find the relevant rows If the table has billions of rows, this can take hours If there is an index on the relevant column(s), Oracle can search the index instead An index is a sorted list of key values, structured in a manner that makes the search very efficient With each key value is a pointer to the row in the table Locating relevant rows via an index lookup is far faster than using a full table scan, if the table is over a certain size and the proportion of the rows to be retrieved is below a certain value For small tables, or for a WHERE clause that will retrieve a large fraction of the table s rows, a full table scan will be quicker: you can (usually) trust Oracle to make the correct decision regarding whether to use an index, based on statistical information the database gathers about the tables and the rows within them A second circumstance where indexes can be used is for sorting A SELECT statement that includes the ORDER BY, GROUP BY, or UNION keyword (and a few others) must sort the rows into order unless there is an index, which can return the rows in the correct order without needing to sort them first A third circumstance when indexes can improve performance is when tables are joined, but again Oracle has a choice: depending on the size of the tables and the memory resources available, it may be quicker to scan tables into memory and join them there, rather than use indexes The nested loop join technique passes through one table using an index on the other table to locate the matching rows; this is usually a disk-intensive operation A hash join technique reads the entire table into memory, converts it into a hash table, and uses a hashing algorithm to locate matching rows; this is more memory and CPU intensive A sort merge join sorts the tables on the join column and then merges them together; this is often a compromise among disk, memory, and CPU resources If there are no indexes, then Oracle is severely limited in the join techniques available TIP Indexes assist SELECT statements, and also any UPDATE, DELETE, or MERGE statements that use a WHERE clause but they will slow down INSERT statements. excel qr code formula Generating QR Code barcodes from cells in Excel using VBA and ...
