may or may not be a default constraint that needs to be dropped before the renaming. But it all works....UNLESS....anything I haven't conceived of happens. One of those things was finding out that one of the tables on my list actually had both a Big and and IsBig column, in which case this script didn't fail, just skirted around the table, kept processing other tables, and gave no error or exception.Where and with which constructs should I begin?---retrieves tables to changeUSE DatabaseNameGODECLARE @TableName varchar(max)DECLARE getTableName CURSOR FORselect ss.name + '.' + o.name as table_namefrom sys.objects ojoin sys.schemas ss on ss.schema_id = o.schema_id where type = 'u' andss.name + '.' + o.name in('mgo.tablename1','sbr.tablename2','dkl.tablename3'); OPEN getTableName FETCH NEXT FROM getTableName INTO @TableName WHILE @@FETCH_STATUS = 0 BEGIN declare @default varchar(max) declare @table_name varchar(max) set @table_name = @TableName set @default = null ---- identify if default constraint on Big column existsSELECT @default = d.namefrom sys.tables t join sys.default_constraints d on d.parent_object_id = t.object_id join sys.columns c on c.object_id = t.object_id and c.column_id = d.parent_column_idwhere t.name = SUBSTRING(@Table_Name,5,50)and c.name = 'Big'if @default is not nullBEGIN---- ren

T-SQL in SQL Server 2008 still provides access to these tools, but also supports modern structured error handling similar to that offered by other high-level languages such as C++, C#, and Visual Basic. In this chapter, sql error I will discuss legacy T-SQL error-handling functionality and the newer structured error-handling model in T-SQL. This chapter introduces tools useful for debugging server-side code, including T-SQL statements and the Visual Studio IDE.

This part is also available in a Spanish translation by Geovanny Hernandez. Introduction This article is the first in a series of three about error and transaction handling in SQL Server. The aim of this first article is to give you a jumpstart with error handling by showing you a basic pattern which is good for the main bulk of your code. This part is written with the innocent and inexperienced reader in mind, why I am intentionally silent on many details. The purpose here is to tell you how without dwelling much on why. If you take my words for your truth, you may prefer to only read this part and save the other two for a later point in your career. On the other hand, if you question my guidelines, you certainly need to read the other two parts, where I go into much deeper detail exploring the very confusing world of error and transaction handling in SQL Server. Parts Two and Three, as well as the three appendixes, are directed towards readers with a more general programming experience, although necessarily not with SQL Server. This first article is short; Parts Two and Three are considerably longer. Table of Contents Introduction Index of All Error-Handling Articles Why Error Handling?
