saIKIRAN May 10th, 2015 asked about the second highest age so as per our common sense (for eg: who are joined in an organization first those persons age will be high when compare to the latest recruited persons ) ............ However,queries that return more than one row you must declare an explicit cursor or use a cursor FOR loop.Explicit cursor is a cursor in which the cursor name is explicitly assigned to a SELECT statement via the CURSOR...IS statement

At the time of writing, Oracle 10g is being launched and who knows what further improvements are included? Perhaps a solution to the "implementation restriction" that prevents FORALL from accessing individual attributes in collections of records? Perhaps a BULK COLLECT into an associative array indexed by VARCHAR2? It is understood that FORALL will be able to process non-contiguous arrays for the first time. This will cause two iterations of our FORALL statement to error but rather than fail the entire transaction, we will report the errors (in a production system you would probably store these off in an exceptions table) and allow the "clean" data to process through
flashback table in 10g
a warning on indexes and constraints When a table is dropped without purge, any additional segments "belonging" to the table (such as indexes or LOBs) are also renamed and recorded in the recycle bin. the table has row movement enabled, either by an ALTER TABLE or at the time of CREATE as in the demonstration table above; and the user performing the flashback has either the FLASHBACK ANY TABLE system privilege or the FLASHBACK grant on the target table
Tunde Top Best Answer 0 Mark this reply as the best answer?(Choose carefully, this can't be changed) I have one command namely...Bulk script command but somehow i am getting syntax error in that. It's a simple, monthly task for me (with some preseted control files and prepared unix shell cmd-s I have only to modify sometimes), but I shall consider the other offers I could read from the previous answers
If you set the isolation level of the main transaction to SERIALIZABLE, changes made by its autonomous transactions are not visible to the main transaction when it resumes: SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; Controlling Autonomous Transactions The first SQL statement in an autonomous routine begins a transaction. You use them when you want to perform a query in one subprogram, and process the results in a different subprogram (possibly one written in a different language)

See Also: "Subprogram Parameter Aliasing with Parameters Passed by Reference" In Example 12-18, the intention is to select specific values from a collection, numbers1, and then store them in the same collection. However, because the compiler inlines subprograms early in the optimization process, it is possible for subprogram inlining to preclude later, more powerful optimizations
SQL FAQ - Oracle FAQ
COMMIT - save work done SAVEPOINT - identify a point in a transaction to which you can later roll back ROLLBACK - undo the modification I made since the last COMMIT SET TRANSACTION - Change transaction options like isolation level and what rollback segment to use SET ROLE - set the current active roles DML are not auto-commit. If you include the SAMPLE clause within a multi-table or remote query, you will get a parse error or "ORA-30561: SAMPLE option not allowed in statement with multiple table references"
SQL Server: Select query from one database and insert into a table in another database
There are obviously many ways to accomplish that, including elaborate UPDATE queries with anywhere from one to numerous REPLACE functions (even within REPLACE functions). I have a simple query I am wanting to insert into a VBSCRIPT .VBS file to run a query against a DB and output the source to a CSV file locally on the computer then email the document to a specific email address with out outlook
By default, your stylesheet will be loaded after the theme stylesheets, which means that your rules can take precedence and override the theme CSS rules. SQL copy tables to new table When performing this command, a table will created using the same data types as the columns which as selected in the select statement
Insert Into Oracle FROM Sql Server over Linked Server
Do you know if there a way to convert that datetime value into another datatype (varchar?) in the sql server select statement I use to populate my table? Then I would need to just go from varchar (for example) to the Oracle timestamp field. The SQL Server field could work like an Oracle timestamp if you populate the field with an INSTEAD OF trigger to make sure it is current.If you transfer data from Oracle to SQL Server and want to maintain the original values, you could use ALTER TABLE to disable the timestamp trigger and then reenable it after the transfer
If data is huge, if there are any Non-Clustered indexes that are not build on primary key or unique key, then disable those indexes, loading will be much faster. How can I fix? I have SQL Server 2008 and Visual Studio 2008 and am trying to automatically insert new records into a child table based on new inserts into its parent table
sql - Oracle Insert via Select from multiple tables where one table may not have a row - Stack Overflow
If you are concerned about performance, you would be better to check if the values you intend to bind are null or not and then issue different SQL statement to avoid the OR
