When there’s a table with a primary key that is an IDENTITY and you want to remove the IDENTITY property, there’s no simple SQL code to do it. It is not a trivial task. In fact, there’re many steps to be done and it’s better to do all of them inside a single transaction, to avoid to leave the database in a inconsistent way (without FK, or . . .
I’ve found three ways of getting user permissions (grants and denies) in SQL Server:
- SQL Server Management Studio: It’s OK and user-friendly. But it’s not an option if you’ve a large farm of servers or you want to script it and create task to run the checks.
- Impersonate as the user and check its permissions.
- SELECT on system tables to see . . .
Why it's important to buy a good RAID controller
I write this post to explain a problem I found with a RAID controller. One morning I was notified that PostgreSQL in one development server was stopped. I connected to it and I found the service stopped. It was a physical server running Windows Server 2008 R2 and PostgreSQL 9.0. The server had a RAID 1. It’s important to notice that Windows . . .
Pyrseas is a Database Version Control for PostgreSQL with a very interesting approach and with an easy way to script a database (database to a YAML file) and to apply changes to a database (YAML file to a database). It’s develped in Python by Joe Abbate (thank you Joe for it!)
Currently I’m using
dbtoyaml to script the database in every . . .
Don't let it to the system configuration
Implicit date format conversions, when no format is specified, are always a source of troubles when:
- Passing dates as parameters in scripts to databases, other scripts, applications, web services or other targets, because each system is waiting the dates in specific format.
- Running a SQL script in databases with different language settings. . . .
It’s a good practise to use the Write-Verbose,Write-Debug and other about_CommonParameters when writing functions because it helps you to write clean code in a very integrated way with Powershell. One of its main benefits is for debugging and verbosing without needing to modify your code.
I’ll focus on the usage of
Write-Verbose. The others . . .
I really like Powershell because you can do a lot of tasks very easily and it’s very integrated with Windows and .NET framework. So, it’s powerfull.
Get-ChildItem it’s a versatile and useful cmdlet that gets the items and child items in one or more specified locations. In this post I write some code examples that I hope you find it useful for . . .
