SQL Server Memory Usage Continue To Increase

Dec 28, 2004

On the last Sunday 26/12/04 on 20:00 I got on one of our applications in the customer site this error:
"There is insufficient system memory to run this query."


Computer: IBM XSERIES_345, dual CPU 2.8 Intel xeo, 1,047,952 KB ram, windows 2000 server sp4.
Disk space: 4395 MB, Virtual memory: initial size 1536 MB, Max size 3072 MB. Registry size: current 14 MB, Max 90 MB.

SQL Server 2000 SP 3, two production databases (1) Data size 100 MB, log size 15 MB (2) Data size 500 MB, log size 125 MB
All the memory options are configured as default i.e. dynamically configure for memory and not changes in any sp_configure options.

SQL server is the only major application running on the machine.

On that evening the I've checked the Task Manager and found that SQL Server use 500 MB in Mem Usage and 1200 MB in VM size.
In the query analyzer I execute the select query which results the "…insufficient system memory…" error on both databases and on the one with more data it failed with this error, but on the other database it completed successfully.
I restart SQL Server service to solve it, and as for today 28/12/04 at 08:00 it use 590 MB in Mem Usage and 590 MB in VM size.

I have checked the system with Performance monitor and didn't find any problems I use the Memory: Pages/sec, Memory: Available Bytes, Physical Disk: % Disk Time, Processor: % Processor Time, SQL Server Buffer: Buffer Cache Hit Ratio.

We have 8 user connections for one of the database and 16 for the other one.
Our system runs with this configuration for 2 months, I backup the databases FULL, DIFF and LOG backup.
It's not real time system, and the load on the SQL is medium, but we use bad queries as update for all fields in one query (please don't ask…)

I know that SQL server is greedy with the memory and released memory only if other process needs it.

Any ideas why it happens?

SQL Server 2012 :: Curious Use Of Percentage On Where Clause

I found a code snippet that use the curious following sintax on the creation of View:

CREATE VIEW [dbo].[vw_EvenValues]
SELECT [TestColumn]
FROM [dbo].[TestTable]
WHERE [TestColumn] % 2 = 1


IF [TestColumn] on the Select is varchar, then error occurs and say:"Conversion failed when converting for the varchar value 'A001' to data type int"

SQL Server 2012 :: Grouping By Percentage Of Time Worked By Person

Jul 2, 2014

I have a table of People and their ID, the starting month (a fixed number of months, say 10 for this), the ending month, and the percent of work time (0-1 being 0-100%). If they have a % work of 0, I do not want to see anything. But if the % changes, from say .5 to .75, I would need the first and last month they were at .5, and the first and last month they were at .75

The Table:

/****** Object: Table [dbo].[TestProject] Script Date: 02.07.2014 10:15:08 ******/
IF OBJECT_ID('TempDB..#TestProject2','U') IS NOT NULL
DROP TABLE [dbo].[#TestProject2]
CREATE TABLE [dbo].[#TestProject2](

[Code] ....

The data:

--===== All Inserts into the IDENTITY column
INSERT INTO #TestProject2
("ID","PersonID", "PercentLoad","MonthID")
SELECT 1,123456,0,1 UNION ALL

[Code] ....


Person ID StartMonth EndMonth LOADPCT
123456 3 4 .5
123456 5 6 1
654321 1 2 1
654321 4 4 .5
654321 5 6 .75
654321 7 9 .5

SQL Server 2012 :: Best Way To Handle Like Percentage On Column Too Large For Index

Sep 18, 2015

We have a table to 100M rows and up until now we were fine with an non clustered index a varchar(4000) because we never went above 900 bytes (yes it is a bad design).We have the need to support international character sets now so the column was updated to nvarchar(4000) and now we have data past the 900 byte limit.

The data is long, seems useless but is needed by the business and they need to be able to search "where bigcolumn like 'test%'". With an index, even with a huge amount of data, it was 'fast'. Now of course without an index it is unusable. The wildcard is always at the end of the search. I made a full text index on the column and basic queries such as: select * from ourtable where contains(bigcolumn, 'AReallyLongStringofTextHere') works fine unless there is a space in the data. We loose thousands of returned rows because of spaces in the data.

I have tried select * from ourtable where contains(bigcolumn, '"AReallyLongStringofTextHere that includes spaces"') but not all of the data is returned. I get 112 rows with the contains statement. The table scanning statement of "select * from ourtable where bigcolumn like 'AReallyLongStringofTextHere that includes spaces%' returns 1939 rows.I understand that a full text index is breaking the long string up since it contains spaces. Is there a way to retain the entire string as 1 index entry or is there a way to fix my query to return all of the rows?

SQL Server 2012 :: Calculation Based On Count Function To Format As Decimal Value Or Percentage

Dec 4, 2014

I'm trying to get a calculation based on count(*) to format as a decimal value or percentage.

I keep getting 0s for the solution_rejected_percent column. How can I format this like 0.50 (for 50%)?

select mi.id, count(*) as cnt,
count(*) + 1 as cntplusone,
cast(count(*) / (count(*) + 1) as numeric(10,2)) as solution_rejected_percent
from metric_instance mi
INNER JOIN incident i
on i.number = mi.id
WHERE mi.definition = 'Solution Rejected'
AND i.state = 'Closed'
group by mi.id

id cnt cntplusone solution_rejected_percent
-------------------------------------------------- ----------- ----------- ---------------------------------------
INC011256 1 2 0.00
INC011290 1 2 0.00
INC011291 1 2 0.00
INC011522 1 2 0.00
INC011799 2 3 0.00

Get Percentage From Two Columns

Feb 12, 2008

I am trying to get the a percentage from two columns, but I can not figure out how to do it. An example of my data is:

Red 1000 78
Blue 1000 247
Yellow 1000 472

My thoughts was to do something like:
FROM TableName

When I do this the PERCENTAGE column just has 0s. Could someone tell me can this be done....and what am I missing.

FYI: Columns MAX and ACT are Int (4)

SQL Server 2008 :: Usage Of Built-in Functions On Columns Ignores / Excludes Indexes On That Column?

May 25, 2015

Somewhere i read..that in SQL Server...usage of Built-in Functions on Columns, makes query optimizer to ignore indexes on that column...!

So lets say we have table EMP with Emp_id and Emp_Name....

Also we have Non-Clustered index on Emp_Name.

So following query would NOT use Non-Clustered index on Emp_Name column.

SELECTLEFT(emp_name, 3) as emp3

Is this true? i am using SQL Server 2008.

SQL 2012 :: Memory Usage Extremely High And Causes Server To Crash

Jun 11, 2015

I have been having issues with our SQL server for awhile now. It seems to run out of memory every few days and when I look at the memory dump, the MEMORYCLERK_SQLOPTIMIZER seem to take over memory and eventually cause the server to crash.

Here is the SQL verison we are using: Microsoft SQL Server 2012 (SP1) - 11.0.3460.0 (X64) Jul 22 2014 15:22:00 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.2 (Build 9200: ) (Hypervisor)..It is on a VM on Windows 2012 server. It has 20gb of RAM allocated to it and the MAX Server Memory is set to 16.5gb.

I have seen the MEMORYCLERK_SQLOPTIMIZER grow to about 11gb at the time of the server crash. Why that is happening? What is causing the memoryclerk_sqloptimizer to get so high? I have looked it up and it looks like it has to do with ad hoc requests, but is there something I can do to bring that memory down when it gets so high so that I can prevent a server crash?Do we just need to add more memory or is there a memory leak somewhere?

SQL 2012 :: Percentage Of Rows That Meet Multiple Criteria?

Jun 2, 2015

I am working on a project that was assigned to me that has to do with data in one of our SQL databases. I have the following query that takes information from a single table and averages test scores for each student.

--Group all scores from same student and average them together

with cte_names as
SELECT StudentID, MAX(StudentName) AS StudentName
WHERE schoolYear='2014-2015' AND term = 3


I now need to take the results from the above query and determine the percentage of students, per school that scored a 2 or greater in grade 7 for each test. For grade 8 scored a 2.5 or greater, grade 9 scored a 3 or greater, grade 10 scored a 3 or greater, grade 11 scored a 3.5 or greater, and grade 12 scored a 3.5 or greater.

SQL 2012 :: How To Track SPs To TempDB Usage

Apr 10, 2015

I can get a snapshot of tables in tempDB, but I would like to track which procs are causing the load in the tempDB.

I think I can sample and record objects in the tempdb, but I would like to record the proc creating the most tempDB usage, and disk read/writes associated with those procs.

The DMV's give usage in the individual DB's, but what's a good way to correlate procs in the DB's to tempdb usage?

SQL 2012 :: How To Find CPU Usage From History

I am trying to find out CPU utilization from the history using process.%processor time. I am having dual core CPU with 2 numa nodes each having 16 logical cpus bind to it.

how to calculate the CPU utilization using perfmon.I tried to use SQL query which gives CPU history using SQL DMV, but I am unable to get the exact value. Because in between I have used the same querry to capture my CPU usage on the run day, the value on run day and the query which iam tryting to pull out is different. I am using the same query to pull the history data with providing the date.

-- Get CPU Utilization History (SQL Server 2008 and above)

SELECT @ts =(SELECT cpu_ticks/(cpu_ticks/ms_ticks)
FROM sys.dm_os_sys_info);
SELECT SQLProcessUtilization AS [SQLServer_Process_CPU_Utilization],
SystemIdle AS [System_Idle_Process],
100 - SystemIdle - SQLProcessUtilization AS [Other_Process_CPU_Utilization],

SQL Server 2012 :: Where Clause On Multiple Columns?

May 16, 2014

Right now I have to do something like this and it is time consuming every time I have to query a specific table...

SELECT lots_of_columns
FROM table
WHERE (column5 = '1' OR column6 = '1' OR column7 = '1' OR column8 = '1' OR column9 = '1' OR column10 = '1' OR column11 = '1' OR column12 = '1')
AND other_query_critiera_here

Typing out the OR statement gets long, time consuming and prone to errors because that first where line with all the ORs can sometimes have 20+ ORs in it. As some insight, the columns are text columns, sometimes they have data, sometimes they are NULL. Sometimes they have the same data (i.e., column5 and column6 and column12 could both have '1' as values).

SQL Server 2012 :: Adding New Columns To A Table

Apr 28, 2015

I am planning to add some new columns to an existing sql server 2012 table. I know that I need to use the alter statement to accomplish this goal. However my questions is the location of where I want to add the new columns to the table. It would make more sense to add the new columns to the middle of the table since these columns have a similar meaning as other columns in the middle of the table.

However is it better to add these new columns at the end of the table? I am asking this question since I am thinking I might need some sql to move the values of existing columns and values around?

Thus is it better to add new columns to a table in the middle of the table, at the end of the table, or at the end of the table? If so, why one location is better than another location?

is there a way to do this?

i can do a temporary table and then an update query to add the values to those columns.

just not sure how to get the next value and then the next etc.
