I need a query to know (calculate) the size used by a record in a field by table, I was tried with the follow query (but this only show me the max length of the data type):
SELECT c.name AS column_name
,c.column_id
,t.name AS type_name
,c.max_length
,c.precision
,c.scale
FROM sys.columns AS c
JOIN sys.types AS t ON c.user_type_id=t.user_type_id
WHERE c.object_id = OBJECT_ID('dbo.bloqueos_2005')
ORDER BY c.column_id;
GO
I was tried whit the system views that contains column info, but no one give me the correct information.
If any one have the query or know some way to do this, please help me.
How do I calculate the Record size? I mean the Row size for each table. I heard that there are formulas to do that and the calculation is different for Fixed lenght Columns and Variable length Columns.
I need to calculate the record size for nearly 500 tables.This will help me to decide on the DISk capacities.
Suggest me if any scipts or calculations already available.
Hi,In MS SQL Server, while creating the table, I am getting a warningmessage saying like "maximum row size can exceed allowed maximum sizeof 8060 bytes".Is there any way in SQL Server, to increase this allowed maximum rowsize?The setting like "set ANSI_WARNINGS OFF" is not suitable in my case. Ineed creation of table with around 11000 bytes in the record (Summationof precision of all the columns). And more over, I do not want to looseany data (truncation) in inert operation to keep on the whole recordsize to 8060B.Thanks a lot in advance.Ramakrishna.
I want to calculate average row size of a record. By based on this i want to add some more columns into an existing table. Here is my table structureCREATE TABLE patient_procedure( proc_id int IDENTITY(1,1) CONSTRAINT proc_id_pri_key PRIMARY KEY, patient_id int NULL, surgeon_name varchar(40) NOT NULL, proc_name varchar(20) , part_name varchar(30), wth_contrast int , wthout_contrast int , wth_wthout_contrast int, xray_part varchar(60), arth_area varchar(30), others varchar(30) , cpt varchar(20) , procedure_date smalldatetime NOT NULL, mraloperrun varchar(20),CONSTRAINT patientid_foreign_key FOREIGN KEY(patient_id) REFERENCES dbo.patient_information (Patient_id)) Now i got a requirement that i have to add two more procedures with different columns.The columns overall size is 195 bytes.I can place those two procedures as seperate tables. I dont want to do that becuase of front end requirements.Here the problem is when the user enters these two procedures information remaining fields will store the null value. I know that when we store the null values into corresponding columns min of 1 byte will be occupied. Please suggest me that shall i include these columns into the above table. If i add these columns is performance will be decreased or not. Waiting for valuable suggestions.
Let's imagine some situation in MS SQL 2005: Table t_sample with single column SampleString of type varchar(200). If to this column will be inserted value containing 4 chars, real record (not column) size in database would be 4 or 200? In other words: do MS SQL 2005 records have always constant size (total size of all columns max sizes) or real size of record depends on actual size of inserted data?
Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
Hi, i use this script that show me the size of each table and do the sum of all the table size.
SELECT X.[name], REPLACE(CONVERT(varchar, CONVERT(money, X.[rows]), 1), '.00', '') AS [rows], REPLACE(CONVERT(varchar, CONVERT(money, X.[reserved]), 1), '.00', '') AS [reserved], REPLACE(CONVERT(varchar, CONVERT(money, X.[data]), 1), '.00', '') AS [data], REPLACE(CONVERT(varchar, CONVERT(money, X.[index_size]), 1), '.00', '') AS [index_size], REPLACE(CONVERT(varchar, CONVERT(money, X.[unused]), 1), '.00', '') AS [unused] FROM (SELECT CAST(object_name(id) AS varchar(50)) AS [name], SUM(CASE WHEN indid < 2 THEN CONVERT(bigint, [rows]) END) AS [rows], SUM(CONVERT(bigint, reserved)) * 8 AS reserved, SUM(CONVERT(bigint, dpages)) * 8 AS data, SUM(CONVERT(bigint, used) - CONVERT(bigint, dpages)) * 8 AS index_size, SUM(CONVERT(bigint, reserved) - CONVERT(bigint, used)) * 8 AS unused FROM sysindexes WITH (NOLOCK) WHERE sysindexes.indid IN (0, 1, 255) AND sysindexes.id > 100 AND object_name(sysindexes.id) <> 'dtproperties' GROUP BY sysindexes.id WITH ROLLUP) AS X ORDER BY X.[name]
the problem is that the sum of all tables is not the same size when i make a full database backup. example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?
I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual (empno, accrued_vacation, accrued_sick_effective_date, accrued_sick, import_date)
I need to write a process to get file size in kb and record count in a file. I was planning on writing a c# console app that takes the file path and name as a param however should i use a CLR?
I cant put a script in the ssis when it's bringing the file down because it has been deemed that we only use ssis for file consumption.
Hi... I was hoping if someone could share me some thoughts with the issue that I am having at the moment.
Problem: When I run the package in my local machine and update local SS DB/table - new records writes OK in the table. BUT when I changed my destination meaning write record into another physical SS DB/table there is no INSERT data occurs. AND SO when I move/copy over that same package into another server (e.g. server that do not write record earlier) and run it locally IT WORKS fine too.
What I am trying to do is very simple - Add new records in a SS table using SSIS . I only care for new rows and not even changed rows. Here is my logic - 1. Create Ole DB source to RemoteSERVER - using SELECT stmt 2. I have LoopUp component that will look for NEW records - Directs all rows that don't find match and redirect rows (error output). 3. Since I don't care for any rows that is matched in my lookup - I do nothing or I trash the rows 4. I send the error rows (NEW rows) into OleDB destination
RESULTS when I run the package locally and destination table is also local - WORKS FINE; But when I run the package locally and destination table is in another Sserver (remote) - now rows is written.
The package is run thru BIDS manually so there is no sucurity restrictions attached to it.
I am not sure what I am missing. And I do not see error in my package either. It is not failing.
In SQL Server 2000, I have a parent table with a cascade update to a child table. I want to add a record to the child table whenever I add a table to the parent table. Thanks
I would like to find out how to capture record count for a table in oracle using SSIS and then writing that value in a SQL Server table.
I understand that I can use a variable to accomplish this task. Well first issue I run into is that what import statement do I need to use in the design script section of Script Task. I see that in many examples following statement is used for SQL Server databases:
Imports System.Data.SqlClient
Which Import statement I need to use to for Oracle database. I am using a OLE DB Connection.
Previously same records exists in table having primary key and table having foreign key . we have faced 7 records were lost from primary key table but same record exists in foreign key table.
I have a table in different databases with the same name. My goal is to compare the two tables, and insert a record into the second table where there is not a match in the first table.  So far, my query looks like the following:
SELECT [metal] FROM [ProductionDatabase].[dbo].[Metalurgy] EXCEPT SELECT [metal] FROM [TestDatabase].[dbo].[Metalurgy]
This gives me a list of records from [Production].[dbo].[Metalurgy] which do not reside in [TestDatabase].[dbo].[Metalurgy]. Now, I need to use that list to insert missing records into [TestDatabase].[dbo].[Metalurgy]. How can I modify the above code to INSERT the missing records?
Hi, We want to compare one record in a table with other remaing records of the table that meet a criteria of a business logic.
eg.I have startcall_time,end_calltime as fields with other 50 fields. As a business logic we need to subtract start_calltime of new record from end_calltime of previous record and do some calculations.These calculations have to be done for all the calls where endcalltime(of a record)-startcall(timeof a different record )meet a criteria.
All- Supposing I have table_a and table_b. Table_a has fields FIRST_A and LAST_A for people's first and last names. Similarly, table_b has FIRST_B and LAST_B for people's first and last names.
How would I create a record in table_b for each record in table_a, such that for each added record, the values of FIRST_A is copied to FIRST_B and LAST_A is copied to LAST_B. (Table_b will have other fields that are left unfilled.)
Both are related through vacation_id. Every vacation however has many pictures. I need a query where the result would give me back all records (vacations) from Table 1 with only 1 record from Table 2(one image per vacation).
The largest table in our database eats up above 4G . we do "sp_spaceused" for this table.The length of all columns of this table ( just int, char, varchar, money ,numeric fields types) is about 200 bytes, and the table has around 1,300,000 rows, but the reserved spaced for this table is 4,800,000kb and the data space is around 4,600,00kb.
How can average each row take 3.7kb ( the total size of all columns just 200 bytes)? Any other things I need check? Any one can give any suggestion what cause this problem? or it is normal?
I am wondering if there is the limitation of maximum table size in SQL 6.5. I have a table with 2.6GB and 12,000,000 rows in SQL 6.5 database. Is this a problem?
Is there a practical size limit, in MB's, of a table in SQL Server 6.5?
Is there a size, that once exceeded, degrades performance signifigantly?
I am speaking of raw megabytes. The table in question will consist of only 3 int columns but has the possiblity of becoming VERY LARGE (+1,000,000 rows). I am still in the design phase and can change my strategy if this will prove to be a problem.
I am trying to solve this problem for quite some time.. I was wondering if I can get some help..
These questions are all abt. MSSQL 6.5
1. Is there a limit on the size of the table ? 2. Does it make sense to have more tables if the size of the row size is more that the limit set by 6.5 or i should let have more rows in a different table with duplicate entries for a particular field. 3. What is the number of rows before the performance of a query starts getting affected..
