Sql – Installing sql server express: VS2008 sp1 problem

sql serversql-server-2008sql-server-express

I am trying to install SQL server express 2008 on my machine. I get an error message that says that older version of VS 2008 in installed on the computer. Upgrade to VS2008 SP1 before installing Sql server 2008.

I tried to install sp1 but I get an error message that a compatible version of vs2008 is not detected on the system. the upgrade is not compatible with express editions.

I am having trouble installing sql server 2008 express installed on my machine and I am having problems. Please help me.

I had the same problem that ironsavior describes. I had VS 2008 SP1 and no other VS installed (i.e. no Express edition of anything.)

Here's how I solved it, basically a registry incentive. I went to the the registry key HKLM\SOFTWARE\Wow6432Node\Microsoft\DevDiv\VS\Servicing\9.0\IDE\1033 and changed the following values (they used to be 0, 0, and "RTM" respectively)

SP = dword:00000001
SPIndex = dword:00000001
SPName = "SP1"

You don't even need to quit the installer to do this. Just rerun the checks after the registry tweak and it should pass. At least worked for me.

Syntax:

ALTER TABLE {TABLENAME} 
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL} 
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
WITH VALUES

Example:

ALTER TABLE SomeTable
        ADD SomeCol Bit NULL --Or NOT NULL.
 CONSTRAINT D_SomeTable_SomeCol --When Omitted a Default-Constraint Name is autogenerated.
    DEFAULT (0)--Optional Default-Constraint.
WITH VALUES --Add if Column is Nullable and you want the Default Value for Existing Records.

Notes:

Optional Constraint Name:
If you leave out CONSTRAINT D_SomeTable_SomeCol then SQL Server will autogenerate
a Default-Contraint with a funny Name like: DF__SomeTa__SomeC__4FB7FEF6

Optional With-Values Statement:
The WITH VALUES is only needed when your Column is Nullable
and you want the Default Value used for Existing Records.
If your Column is NOT NULL, then it will automatically use the Default Value
for all Existing Records, whether you specify WITH VALUES or not.

How Inserts work with a Default-Constraint:
If you insert a Record into SomeTable and do not Specify SomeCol's value, then it will Default to 0.
If you insert a Record and Specify SomeCol's value as NULL (and your column allows nulls),
then the Default-Constraint will not be used and NULL will be inserted as the Value.

Notes were based on everyone's great feedback below.
