So, a basic CREATE TABLE statement looks like this in my code (Listing 2-13): Listing 2-13 I keep DDL pretty simple. Customer (CustomerID int identity PRIMARY KEY, CustomerName varchar(40) NOT NULL, Address varchar(60) NULL, City varchar(20) NULL, State char(2) NULL, Zip varchar(10) NULL DEFAULT 'TX', Country varchar(20) NULL, Phone varchar(24) NULL, Fax varchar(24) NULL ) Part I: The Basics 51 52 Part I: The Basics Owner Qualification Because qualifying an object name with its owner can actually improve performance, I try to remember to owner-qualify all object references.
This technique is used with a number of SQL Server's own extended procedures. Many of them are wrapped in system stored procedures that have no purpose other than to make the extended procedures they call a bit handier. Listing 1-19 is an example of a system procedure wrapping a call to an extended procedure: 34 Part I: The Basics Part I: The Basics 35 Listing 1-19 System procedures are commonly used to "wrap" extended procedures. sp_hexstring @int varchar(10)=NULL, @hexstring varchar(30)=NULL OUT /* Object: sp_hexstring Description: Return an integer as a hexadecimal string Usage: sp_hexstring @int=Integer to convert, @hexstring=OUTPUT parm to receive hex string Returns: (None) $Author: Khen $.
RAISERROR can reference an error message added to the sysmessages table via the sp_addmessage system procedure, or you can supply it a message string of your own. If you pass a custom message string to RAISERROR, the error number is set to 50,000; if you raise an error by number using a message ID in the sysmessages table, @@ERROR is assigned the message number you raise. RAISERROR can format messages similarly to the C PRINTF() function, allowing you to supply your own arguments for the error messages it returns.
