Exercises What value does passing parameters to a cursor provide? How can a cursor be defined to accept parameters? Writing CURSOR FOR Loops As given evidence in the previous examples, quite a bit of usage surrounding cursors involves selecting data and performing operations on each row returned by the cursor. Exercises What predefined exception is used to identify the situation where no data is returned by a select statement? What predefined exception is used to identify when the datatype of the information returned is not the same datatype as the declared variable? Coding the Exception Handler Special attention should be paid now to the actual code of the exception handler

The Pain of Implementing LINQ Providers - ACM Queue
The impetus for building queries into the language is quite simple; it is something that is used all the time; and the promise of a unified querying model is good enough, even before you add all the language goodies that were dropped on us. The reason that you have to approach building a LINQ provider in this way is that you cannot really treat many operations as black boxes where given X output Y
The FIRST function returns the value of expression expr when evaluated in the first row of the group of rows mapped to the pattern variable that is specified in expr. Row pattern quantifiers are referred to as greedy; they will attempt to match as many instances of the regular expression on which they are applied as possible
Implementing Procedure Result Sets
Temporary Tables for the Result Data Oracle Rdb provides three types of tables, BASE tables which hold data, VIEW tables which combine data from several tables, or reduce the data from source tables, and TEMPORARY tables. Definers rights modules are generally preferred over invokers rights procedures simply because they add an extra level of security to the database access
Effective Go - The Go Programming Language
Although the concurrency features of Go can make some problems easy to structure as parallel computations, Go is a concurrent language, not a parallel one, and not all parallelization problems fit Go's model. In essence, it rewrites a piece of HTML text on the fly by substituting elements derived from data items passed to templ.Execute, in this case the form value
The Go Programming Language Specification - The Go Programming Language
Given a struct type S and a type named T, promoted methods are included in the method set of the struct as follows: If S contains an anonymous field T, the method sets of S and *S both include promoted methods with receiver T. Implementation restriction: Although numeric constants have arbitrary precision in the language, a compiler may implement them using an internal representation with limited precision
Big Performance Problem with Merge Statement
Why?Details: I have a relatively large table (about 35,000,000 records, approximately 13 GB uncompressed and 4 GB with page compression - including indexes). Help me, Obi-Wan, you're my only hope! Gail, Grant and Steve are on stage at SQLInTheCity in London right now.If you content yourself with my help, I can try to take a look
The main problem with this is that Proxy Server and DHCP can cause IP addresses to change frequently, which can cause issues with valid customers becoming locked out. Hope this helps, Scott ScottGu - Friday, December 8, 2006 5:36:39 AM Hi Scott I have the same problem as Duncan - getting a Enter Network Password box prior to an Access Denied page
There was a lot of (ahem) voiciferous feedback (including from myself) on the disappearance of Schema View from SSDT and thankfully they've realised the error that they have made. Sure, you can supply default values for those variables but you have the added advantage that they can be overridden from the command-line when deploying using vsdbcmd.exe
FAQ on the Radicore Development Infrastructure
Why is RADICORE no good for building web sites? If you think that the world revolves around a front-end website then you must be working with small websites which are so simple that they do not need a back-end administrative application. In order to determine which piece of data goes where each XML document contains a separate structure element which is obtained from a screen structure file

If else statement in C Program
Reply Link autumn October 31, 2014, 8:37 amcan anyone help me with this program,please? *a program that will accept a non-negative number and able to count how many odd or even numbers inputted by user loop will terminate if the user input negative number.

You can however optimize it yourself easily by creating this Dictionary in your code, easy to do since the dictionary key and value are just simple strings. Your best option here is to get the most maintainable code as the performance benefits you may gain will be offset by the minimal boost you may see between if..then and select case
Implementing Dynamic WHERE-Clause in Static SQL - CodeProject
Using ISNULL ISNULL is a T-SQL System function used to handle NULL values, it takes two argument, the first one is to check for an expression and the second argument is for the replacement value if the check expression value is NULL. Even if its a different Non-Null value to be used for multiple comparisons, you can still play around with simple CASE and searched CASE-functions more efficiently

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"
