Database Size

  • Dear All,

    How to find the database size?

    Will it shows the correct value i.e db size when executing sp_helpdb,?

    Please advise.

    Thanks and Regards,

    Ravichandra.

  • Can you run sp_helpdb 'database_name'

    M&M

  • You can right click the DB in SSMS and go to properties. That is how i find it, or are you trying to use T-SQL only? Then you can query either sysfiles or sys.database_files.

  • Hi there. Sorry for ignoramus question but I"ve jumped into here to try and help a customer out. I am a Splunk admin and not a sql guy but our customer wants me to query his sql databases and report on database and logfile size if possible. Splunk has a db connector into which I can put any query but the account I have only has datareader access to the DBs and so most of the queries I can find will not work. I found exec sp_spaceused but I have to specify every database before that with use "db_name". I saw the 'usealldatabses' (from memory, could be wrong) "secret" command but that doesn't work for me.

    Any clues as to how I might achieve this with this level of access would be great OR what's the lowest level of access I can get this sort of infomration.

    Thanks very much.

  • Exercise your Google-Fu.

    Here[/url]'s one.

    If you google it, you'll find more answers than you can shake a stick at.

  • Don't worry I've certainly been google fooing and I found that one but I get the following when I run it: command="dbxquery", Incorrect syntax near '—'.

    And I get:

    SQL Error (4145):Incorrect syntax near '—'

    An expression of non-boolean type specified in a context where a condition is expected, near 'need'.

    If i try to run it against the database server using Heidi sql.

    Also, the bottom of this page: https://msdn.microsoft.com/en-IN/library/ms186782.aspx lists the permissions required to access sys.master_files which is why i was asking if there was a method to obtain this, or something similar to it, using lesser user rights.

  • "If i try to run it against the database server using Heidi sql."

    Is this a SQL Server database?

    If you're using SQL Server, I would look here... just because it's a great resource:

    http://www.sqlauthority.com

    Yes, it's an indirect answer, but Pinal Dave's website is well worth checking out if you are learning SQL Server.

  • I'm really not going to be able to spread myself across into sql, it's just this one question I thought I'd try and put out there.

    Thanks.

  • what database engine are you writing against? HeidiSQL?

  • No it's an MS SQL Server, I installed HEIDI just so I could run some queries against the sql servers so I could take the Splunk DB connector out of the equation as it's very slow. I don't have access to sql server studio or anything else.

    Sorry I should have made it clear. I have to MS SQL servers that I doin't have access to. I have another windows server that runs Splunk along with Splunk's database connector. I connect from there to the sql dbs with an account I"ve been given that is datareader level access. With that I can query the databases fine but I can't get system type info such as the database and log sizes. To help with testing I installed Heidi on the Splunk server so that I could more quickly test queries agains the sql servers.

    Thanks.

  • The following will fail for databases within which your account is not a db_datareader.

    That's normal. You cannot query a database if you do not have sufficient rights.

    Use an account that has the required rights.
