I have a table where in I store data for every client we have. So, the column used to know which rows belong to which client is through the client_id column
Now, can I have a way to determine the data size in the table for a specific client_id?
Get size of all tables in database, Note: The database compatibility level must be set to 90 or above for this to work Above queries are good for finding the amount of space used by the table N' IT' --AND a2.name = 'MyTable' --Filter for specific table --ORDER BY a3.name,� SQL Server provides a built-in stored procedure that you can run to easily show the size of a table, including the size of the indexes… which might surprise you. Syntax: sp_spaceused ‘Tablename’ Here’s an example of it in action: Highly useful stuff. It’s always interesting to see that the indexes are bigger than the actual data.
There is no such way to check the size for specific ID. But there is a work around for that.
Insert your records for client_id in an empty table and check the space of that table using the command:
This will give you the output like:
name rows reserved data index_size unused TEST 18484 8504 KB 7800 KB 632 KB 72 KB
How to estimate/predict data size and index size of a table in MySQL , Given the table description, I see. 66 bytes per row of data; 4 bytes per row for the primary key; 7 bytes per row for country code index. 3 bytes for the country� DATA_LENGTH is the length (or size) of all data in the table (in bytes). INDEX_LENGTH is the length (or size) of the index file for the table (also in bytes). Armed with this information, we can execute a query that will list all tables in a specific database along with the disk space (size) of each.
If you mean you want to know how many rows are associated with each client, then you can do something fairly simple like this:
SELECT client_id, COUNT(client_id) num_of_items FROM yourtable GROUP BY client_id
How to determine free space and file size for SQL Server databases, At the beginning, size of the database can be set up using the SIZE parameter and how It leaves us with two options either by specific absolute value or by Gigantic sized table data will be dispensed into multiple files in a larger Understanding Log Sequence Numbers for SQL Server Transaction Log� There is no such way to check the size for specific ID. But there is a work around for that. Insert your records for client_id in an empty table and check the space of that table using the command: sp_spaceused newtablename This will give you the output like: name rows reserved data index_size unused
Understanding how SQL Server stores data in data files, As you know, data in tables is stored in row and column format at the You can change the name of the database, file path, file names, size and file growth according to your needs.

Introduction to data.table, This vignette introduces the data.table syntax, its general form, how to subset to a particular function from a potentially huge set of functions available before by knowing precisely the data required for each operation, leading to very fast data.table is an R package that provides an enhanced version of� Similar to Excel, there are multiple ways to determine if a data set contains a specific value using 1010data's GUI. Mirroring the solution from Excel, you can populate a cell, or in 1010data's case, a column of cells, with text stating if the value is "Found" or "Not Clicking on Columns> Create Computed Column, will open the following dialog.

- Did you means disk/resultset data size or did you simply meant that you want to count records.. Question is not totally clear.. See Why should I provide a Minimal Reproducible Example for a very simple SQL query?
- I meant the disk/resultset data size
- @RedDevil's answer should give the disk size, but for the resultset i think you need to write estimating function.. If you want it more preciese you need to reverse engineer a SQL Server client plugin or study the protocol to figure out how large a resultset is protocol wise..
- Thanks Gordon. Based on Red Devil's answer below, does the data column produced by sp_spaceused newtablename give me the bytes of data of only the rows and not the table?
- @RathiRao . . . It returns lots of information, including the total amount of space and the total amount of space used by data and by indexes.
- Thanks Gordon. Should I then use the data column as the actual space consumed by the table rows only?
- ADyson, thank you, I need the data size of a particular client. Not the number of rows
- Please give a precise definition of "data size" then. You mean the number of bytes used to store the data for the all the rows associated to a specific client ID, or something?
- Yes, I meant the number of bytes of data for the rows associated for a particular client_id
- @RathiRao I see. I think you should read Gordon's answer carefully. Due to the way SQL Server's storage system is implemented it is not quite as simple as that.
