SQL Server - Query to get table sizes
Once again I am posting SQL that I have found on the internet (mainly so that I have can find this scriopt easily in the future). This one is thanks to marc_s and can be found in this Stackoverflow post.
The script will give you a breakdown of the table size for each table in your database. This includes a row count, disk space used and disk space available. I have modified the original script slightly as a number of databases I work with have multiple schemas and the original script doesn't show the schema name.

T-SQL script for finding object dependencies
This morning I wanted to find out where a specific stored procedure was being used. I wasn't sure how to do this using T-SQL so did a bit of googling and found this article. I have made a slight enhancement to the scripts shown in the article.
I am sure I will get a lot of milage out of this in the future.
DECLARE @ObjectName VARCHAR(500) SET @ObjectName = 'dbo.sp_test_Proc' -- shows objects that the named object depends on SELECT DISTINCT OBJECT_NAME(DEPID) DEPENDENT_ON_OBJECT, OBJECT_NAME (ID) OBJECTNAME FROM SYS.SYSDEPENDS WHERE ID = OBJECT_ID(@ObjectName) -- shows objects that use the named object SELECT DISTINCT OBJECT_NAME(DEPID) OBJECT_NAME, OBJECT_NAME (ID) USED_IN_OBJECT FROM SYS.SYSDEPENDS WHERE DEPID = OBJECT_ID(@ObjectName)
I am sure I will get a lot of milage out of this in the future.
