You need a basic understanding of the following skills
- Reading and understanding requirements.
- Creating designs
- Creating data models
- Creating databases
And I expect that you are going to also need the following skills
- Internet Security
- Web design
- Basic SQL
- Intermediate Database management and SQL
- Basic user security
- Basic business retail knowledge
You could probably start by learning how to create databases, create tables and use SQL to access them. That would probably take a week.
Then learn about business retail and improve your requirement reading skills. No idea how long that will take you.
The two above together can then be used to create some tables that are at least something like what is needed for the project.
OK, so as I understand it the db_accessadmin role got merged into db_securityadmin in recent versions of SQL server? This is fine, it's better this way.
My question is, when did it happen? I try to cater for all reasonable flavours of SQL server in my system, I recently took great joy in removing support for SQL 7 (The last client using it paid me to migrate their data to 2008r2 via 2005).
Now I'm trying to set up a login with both db_accessadmin & db_securityadmin rights. Or just db_securityadmin, if appropriate. So I need to know which release they merge in. Google is useless on this, so is MSDN.
I could just try to grant the right and suppress the error if it fails, On Error resume next anyone
One day we'll look back on this and plow into a parked car.
I have a SQL Server project that I'm currently adding code to using SSMSE2k8 and beside the fact that this is all TSQL, there's this creep that's occuring in the facility. Namely the .xml. Now, here's the more technical side of TSQL as related to XML, using a FOR XML PATH juncture. I can do a basic SELECT query and get output of xml (pseudo output really because ... this is the creep; in ssmse that's as far as development WENT) but I'm constrained by all these substitutions in he editor:
Could have knocked me over with a feather ... the reason that my editor (was) going south was because of the type I had used to reassign parsed lines of singleline .xml while striking it up as data in a table!.
[nvarchar](MAX) throws (bad use of an alliteration) the phantom formatter into overdrive, while [xml] is silently overlooked. Thus arrows are preserved.
SELECT [xmliform] AS 'data()' FROM [database].[xml].[tblXMLAsTypeNvarchar] FOR XML PATH('')
So, as you can see, an editor will try to format anything from a table where the type is [nvarchar] using it's xml parser when I specify "FOR XML PATH" regardless of how bad I "want" it as xml. And that is with substituted control characters.
ok but this is when that you use COMMIT end of my related code.
but i dont use COMMIT tran in my code.
First, it's a lousy example; there's no way that the server can "guess" whether it should be rolled back or comitted automatically. Second, there is nothing to commit or rollback, since a SELECT statement doesn't change the data. Don't use a transaction when selecting. Also, set <a href="http://msdn.microsoft.com/en-us/library/ms188792.aspx">XACT ABORT</a>[<a href="http://msdn.microsoft.com/en-us/library/ms188792.aspx" target="_blank" title="New Window">^</a>] to ON. Also, don't lock an entire table, unless really, really required.
and if use this code you can see that this table is lock:
hi to all
im face with low performance by below query in sql server 2008 any one can help me.
my query is goon work when top has larg number but when top has less row (for example top 19) this query has low performance for table loaninstallment with amount of records(10000000 R).
any one can help me
thanks for any help
selecttop19 * from(select ROW_NUMBER()over (orderby ID ) as rowNumber,* from BML.LoanInstallment where total_amount like'%80%') tbl
select ID,ROW_NUMBER() over(orderby ID) RowNum from BML.LoanInstallment
selecttop19 * from(select payment_date,total_amount,BML.LoanInstallment.ID,RowNumber from BML.LoanInstallment
#tblTemp on #tblTemp.ID = BML.LoanInstallment.ID
where total_amount like'%80%') tbl
this run completed a large of second
i think the reason of this is my where clause that i use like in this clause and if i remove it my query is ok and response in reasonable time.
what you thinks ?
