Can somebody else please provide feedback and let me know if this is happening to them too? This could be a problem with my internet browser because I've had this happen before. You definitely know what youre talking about, why waste your intelligence on just posting videos to your site when you could be giving us something enlightening to read? 14
ALTER TABLE
Subpartitions and LOB subpartitions of that partition that you create subsequently will inherit these values unless you override them explicitly when creating the subpartition or LOB subpartition. You cannot specify this clause if the column was created or added using the IS OF TYPE syntax, which limits the range of subtypes permitted in an object column or attribute to a particular subtype
The orders in which these are executed are as follows: Table Functions Unique Constraints Check Constraints Indexes You must also edit this script to use your desired collation. Download all scripts and explanation here About Collation Consolidation At some time in your DBA career, you may find yourself in a position when you sit back and realize that your database collations have somehow run amuck, or are faced with the ever annoying CANNOT RESOLVE COLLATION message when trying to join data of varying collation settings
sql server 2008 - Quickly change NULL column to NOT NULL - Database Administrators Stack Exchange
One problem with this is that even if you know the column in fact has no NULLs the constraint is not trusted by the query optimiser which means that the plans can be sub optimal. Adding the constraint with NOCHECK means that no rows will need to be read to verify it, and if you are starting from a position where the column does not contain NULL values (and if you know none will be added between checking and adding the constraint) then, as the constraint prevents NULL values being created from future INSERT or UPDATE operations, this will work
First of all, If there is any application which depends on the order of column it is really not good programming and will create problem for sure in future. With the time passing, the developper must add a colum like Deathday, as the life is not eternal, to notify the death of our preferred singer Miachael Kackson for example
Alter column order
It will take care of dropping and recreating all indices, foreign key constraints, etc as you could well overlook something or make a mistake.I guess it's nice from a database diagram perspective to have the columns nicely ordered and, depending on your reporting tools and how end-users use them it's also nice to have the columns in a particular order. A purist would say that the end user, if they must use a reporting tool, should only be accessing views anyway in which case you can change the columns by simply changing the view
Resize or Modify a MS SQL Server Table Column with Default Constraint using T-SQL Commands
If you execute the below sample t-sql statements command by command, you can see how a column which has a default constraint can be resized or modified using t-sql. As an IT professional working on database programming I had to alter table columns to keep generally more data, so resize and modify their size length without changing the table column data type
SQL Server Forums - Alter table - Add new column in between..
Make sure you run it in pieces.Here is the code: USE Northwind GO PRINT 'This script attempts to reorder a column by updating the system tables themselves. For any column, it is the number of columns in that table with colid's not greater than its own colid.I use similar logic all the time to calculate rankings, with the rank of a given record being 1 + the number of higher-valued records
Question: how do I discern between "user-generated statistics" and "query optimizer generated statistics"? As a T-SQL "IF" statement would be ideal, because I want to make my alter table command conditional upon this
alter table abc ADD dad varchar(50) after parentname But it throws me the following error message Msg 170, Level 15, State 1, Line 1 Line 1: Incorrect syntax near 'after'. If you look at a page of data (for example, by using DBCC PAGE in MSSQL) you will see that the storage order of the fields does not correspond to the order you specified in the CREATE TABLE statement
