sqlplus show all tables command
Unfortunately SQL Server seems to not have a function to get back the result value of a default constraint expression and then saving the expression in case of constant values is also a little bit strange. By doing it in this way, you can generate any type of Static XML, Remember the word Static which i had used over here, you will come to know why i had termed it as Static at the end of this article
SQL 101: Getting Answers with SELECT
Figure 3: The Results tab in the SQL Worksheet In the tool bar, the small green arrow superimposed on the image of a piece of paper is the Run Script icon. When your logical models and physical implementations use meaningful entities and well-chosen datatypes, you have multiple options for accessing the data
How to Create and Manage Partition Tables in Oracle
If you place partitions in different tablespaces then you can isolate problems due to failures as only a particular partition will not be available and rest of the partitions will still be available. The partition value list for any corresponding local index partition is correspondingly extended, and any global index, or global or local index partitions, remain usable
Replicating Transactions Between Microsoft SQL Server and Oracle Database Using Oracle GoldenGate
This options tells the Extract process to routinely check and delete the CDC capture job, resulting in better performance and less occupied space for captured data. The company is now encouraging its customers to use Oracle GoldenGate (which is part of the Oracle Fusion Middleware family) for their data replication needs in new applications
In that case, set the buffer size to a larger value, eg.: set serveroutput on size 200000 If you forget to set serveroutput on type SET SERVEROUTPUT ON once you remember, and then EXEC NULL;. When a trigger tries to reference a table that is in state of flux (being changed), it is considered "mutating" and raises an error since Oracle should not return data that has not yet reached its final state

Verify experience! Anyone considering using the services of an Oracle support expert should independently investigate their credentials and experience, and not rely on advertisements and self-proclaimed expertise
Oracle SQL
After the current transaction has ended with a COMMIT or ROLLBACK, the first executable SQL statement that you subsequently issue will automatically begin another transaction. Every time you create an index (either explicitly with CREATE INDEX or implicitly with a UNIQUE or PRIMARY KEY declaration), you should (on the Stanford Oracle) follow the declaration by TABLESPACE INDX
SQL*Plus Command Reference
EDIT alone places the contents of the SQL buffer in a file by default named AFIEDT.BUF (in your current working directory) and invokes the text editor on the contents of the file. SQL*Plus SET commands such as SET LONG and SET LONGCHUNKSIZE and SET LOBOFFSET may be used to control the size of the buffer while PRINTing CLOB or NCLOB bind variables
Oracle Dynamic SQL
Method 3 This method lets your program accept or build a dynamic query, then process it using the PREPARE command with the DECLARE, OPEN, FETCH, and CLOSE cursor commands. Regardless of the value of DBMS, if you use a VARCHAR variable to store the dynamic SQL statement, make sure the length of the VARCHAR is set (or reset) correctly before you execute the PREPARE or EXECUTE IMMEDIATE statement
sql - Get list of all tables in Oracle? - Stack Overflow
Of course, you may want to exclude certain schemas like SYS and SYSTEM which have large numbers of tables that you probably don't care about because those are all delivered by Oracle
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"
