Error when starting SQLSERVER AGENT
sqlserver agent: "The SQLSERVER AGENT SERVICE on local computer started and
then stopped. Some services stop automatically if they have no work to do,
for example the performance logs and alerts service"
In this server I have windows 2003 and sql server 2000 (it has the service
pack already), actually some days ago it had no problem, suddenly the jobs
did not run so I realized this problem.
Help!!!!!!!!

The MSDB database has some problem,maybe it is running in single user mode.
maybe you moved it from another BD check the MSDB for any thing out of the
normal.

Error Validating Any Check Constraint
I just this day started using SQL sever 2005. I created a database and
then created a table. Then I started adding some fields. I wanted to
add a check constraint to one of the fields called state but I keep
getting the same error. I right click on the field while editing the
table and select check constraint. I then click add on the check
constraint dialogue and in the expression caption I input the
following:
<code>
@.State In('CA', 'AZ', 'UT', 'CO')
</code>
I am using a book and have straight copied the above example from
the book. However when I input the check constraint I get the following
error;
"Error validating constraint 'ck_myfirstdatabase'
I have tried this with other fields and other types of check
constraints and I still get the same error. I have tried to delete the
database and recreate it. I have tried everything I can think of and I
cannot seem to get check constraints to work. I have no idea why I keep
getting this message. I have checked the
examples a
thousand times, the syntax is definately correct. This is getting
extremely annoying as I cannot continue unless I do this. I'm all out
of ideas. Can anyone please tell me
why it could not be working? Any ideas would be greatly appreciated.
hi,
i think this
@.State In('CA', 'AZ', 'UT', 'CO')
should be like this
State In('CA', 'AZ', 'UT', 'CO')
@.state is a varaible and constraints dont use it.
Anyway the best way to learn constraint is to use TSQL scripts and here's an example
create table mytable
(
chardate char(10),
charfloat char(5)
)
GOALTER TABLE MYTABLE
ADD
CONSTRAINT column_chardate_chk
CHECK
(
chardate like '[0-1][0-9]/[3-9][0-9]/[0-9][0-9][0-9][0-9]'
)
GO
ALTER TABLE MYTABLE
ADD
CONSTRAINT column_int_chk CHECK
(
charfloat like '[0-9][0-9].[0-9][0-9]'
)
GOINSERT MYTABLE VALUES('01/01/2005','01.20') this will insert
GO
INSERT MYTABLE VALUES('01/01/2005','001.20') this will failSELECT * FROM MYTABLE
