Because associative arrays are intended for temporary data rather than storing persistent data, you cannot use them with SQL statements such as INSERT and SELECT INTO. When the remote database performs operations such as FIRST and NEXT, it uses its own character order even if that is different from the order where the collection originated

If this is not done, the installer will automatically drop the schema before proceeding to the next configuration assistant.If the Oracle Management Service Configuration Assistant fails before completion, you can click Retry, which automatically cleans up the repository when the configuration tool is rerun. in the beginning there is installed the Oracle 11 software including all patches.After the migration I miss the execution of the post scripts belonging to the patches

No DBMS can stand for long if you have an increase of couple TBs of data coming in daily and yet no increase in batch window, no matter how much money you throw in it .... But life of DBA is much easier with Teradata.As stated before also by me, it might be a rough road to crossover to Teradata from Oracle background but the effort will be worth it

Tuning parameters that were used in original Export and Import, such as BUFFER and RECORDLENGTH, are neither required nor supported by Data Pump Export and Import. When you are importing data into an existing table using either APPEND or TRUNCATE, if any row violates an active constraint, the load is discontinued and no data is loaded

In this article, both of these functions will be explored to see how efficient they are, plus it will cover a few other methods to get the same results. There are two other ways to improve performance, the first one does not use a WHERE clause but instead uses a UNION and LEFT OUTER JOIN to get the same results

Here's some stats from our runs, do you have any tests that show index lookups are actually faster? Our indexed column is varchar2, and the values are not random. This is what I want to avoid, I do not want all databases to have same master key, or the same ewallet.12 file (as suggested by the manual, have different wallets for different databases)

http://hemantoracledba.blogspot.com/2009/07/difference-between-not-in-and-not.html Competition: low
Popular wisdom is that the difference between the two is only in terms of performance (being on the basis of whether the larger table is the "outer" or the "inner" in the query) but that the results are the same.However, we must remember that such an operation being an Anti-Join fails when NULLs are involved

http://stackoverflow.com/questions/173041/not-in-vs-not-exists Competition: low
If the subquery must be correlated with the outer select, then NOT EXISTS may be preferable, since the optimizer may discover a simplification that prevents the creation of any temporary tables to perform the same function. The subquery inside the NOT IN statement can be evaluated at the beginning of the execution, and the temporary table can be checked against each value in the outer select, rather than re-running the subselect every time as would be required with the NOT EXISTS statement

In general the second query would be processed as Loop through t1, for each value in t1 look it up in t2 Which is faster? Well imagine that t1 contains just 2 rows and t2 is large and indexed on column y.

However, there are two indexes that contain them separately: the index on value created explicitly, and the index on id created implicitly to police the PRIMARY KEY. This behaviour was explained in the first article of the series (that concerning SQL Server) and this is a reason why PostgreSQL is reluctant to use an Anti Join for NOT IN

(and use two subqueries, not three - just or the last condition on the last two) If what you say is true, it looks like a bad plan (bug) is being generated for the first query - but I cannot confirm that as I don't have the schema or the entire query and cannot verify that. did you know we can and will rewrite your IN to be Exists, your Exists to be In, your not in as not exists, your not exists as not in??? they are the same to us - we use them as we see fit
