As you may know, in Oracle the syntax from creating a table that is the same as another is: 1 CREATE NEWTABLE AS SELECT * FROM TABLEcreate NEWTABLE as select * from TABLE In SQL Server, the syntax is slightly different: 1 SELECT * INTO NEWTABLE FROM TABLEselect * into NEWTABLE from TABLE Note: This will not copy indexes, constraints, triggers, or other attributes of the table. It will copy the column names, data type, and data only.
I will be placing SQLDataSource examples here shortly. I know there is controversy relating to placing SQL or even Stored Procedure names in .aspx files, but the reality is that for some applications, there is no need to concern ourselves with the complexities related to N-tiered, fully-abstracted, technical-utpoia development. This is especially prevalent when the resources working on an implementation do not have the background or ability (for a variety of reasons not always their own doing) to deliver solutions with these concepts intact each time. Certainly, Microsoft must have agreed as they allow/support this approach. None-the-less, feel free to engage in healthy … Read More
I hit what I considered to be an annoying “issue” in ASP.NET 2.0 the other day that I thought I would share so others can avoid the problem. I created a form with some text controls and an sqldatasource that called a stored proc while accepting parameters via asp:FormParameter. This worked great and tested out fine. Once I added the same code into a Master Page, everything began getting passed as “NULL” (it was no longer finding the FormParameters on the page. After troubleshooting for more time than I preferred, I found out that I can achieve success by using … Read More
Following are some of the best Oracle books for developers. The only thing that gets DBA’s more upset than making a mistake that compromises a production database is when a developer makes the mistake. Even if it is merely culture-driven, developers need to be on top of their game when it comes to database-reliant enterprise applications. It only makes you that much better. Here are some good places to start: Cost-Based Oracle Fundamentals – Jonathan Lewis Expert Oracle Database Architecture: 9i and 10g Programming Techniques and Solutions – Thomas Kyte Effective Oracle by Design – Thomas Kyte
Following is the call that can be made to refresh your materialized view in Oracle manually: 1 EXECUTE DBMS_SNAPSHOT.REFRESH('[MV_NAME]’,'[refresh_option]’);execute DBMS_SNAPSHOT.REFRESH(‘[MV_NAME]’,'[refresh_option]’); Refresh Options: ? – Uses default F or f – Fast C or c – Complete A – Always complete
Are you a TOAD fanatic when it comes to “anything-Oracle”? If so, you probably realized that TOAD will not show you the DDL for a materialized view in any of the tabs in the schema browser. The “Scripts” tab will look similar to a table’s script. Following is an SQL statement you can run to find out the SQL used by the materialized view: 1 SELECT query FROM user_mviews WHERE mview_name='[MV_NAME]’;select query from user_mviews where mview_name='[MV_NAME]’; Enjoy!
This will run only the SQL that your cursor is on. You do not need to highlight the line or the entire SQL statement; simply place your cursor anywhere inside the SQL statement and click SHIFT-F9.
This will verify (parse) the statement without executing it.
This will execute an explain plan on the current statement.
This will bring up your previous SQL statement. If you use SHIFT-F9 and are disciplined about keeping all iterations of executed statements in the screen…
