SQL 2012 :: FullText Search - Can Search Terms Come From Another Table
Mar 25, 2015I have a table that contains words that will be used to search another table where FullText index has been created on searchable columns. I'm basically trying to run something like this:
SELECT t1.col1, t2.col3
FROM tbl1 t1, tbl2 t2
WHERE CONTAINS (t1.col1, t2.col1)
I know this won't work but is there a way to join these two tables so the words (t2.col1) can be passed as search conditions? There is no common key on both tables so normal join won't work. I'm trying to find a way to pass the search words from one table to another.
Search Database For Any Terms Stored Proc Help
May 28, 2008hey all,
basically, what I am trying to achieve to 2 types of search functions...
Search for All terms (easy and complete) and search for Any Terms...
the way I have gone about this so far is to in my asp.net app, split the search string by spaces, and then search for each word, and merging the resulting dataset into the main return dataset.
this, however has a few problems. the result dataset will contain duplicate values, and i am running queries in a loop.
What i am looking for is a one-stop-shop stored procedue that will split the search string, loop through each word, and add the results to a return table, ONLY if it does not exist already within the return table.
Can anyone point me in the right direction... basically with the splitting of the string and the looping through the words...the rest i think i can handle...
or any other hints/tips/tricks would also be helpful.
Thanks Everyone!
Does MS Have A Glossary Of Terms?

Sql Server Express Terms Of Use
Nov 22, 2006Hi
Hopefully im asking this in the right place, sorry if its not, maybe you could point me in the right direction
I have been informed that use of MDF Files (SQL Server Express) Databases on the net was restricted as this was classed as multi connections and therefore was outside the free license agreement.
I am looking at commercially developing and marketing a web based system for with a relatively small database footprint (well under 1gb) with ASP.NET 2.0 and like the look of SQL Server Express.
Could anyone clear up whether or not this is allowed under the SQL Server Express terms of use, or point me in the direction of somewhere i can find information.
Thanks

Is It Possible To Perform Terms Lookup On Unstructured Files ?
Feb 5, 2007Hi,
I need to categorize a lot of html or text files according to a list of terms and I wonder if terms lookup is adequate for this. The problem is that terms lookup can only take an Oledb source as input. My files can be up to 80 Kb big and aren't columns structured.
Should I import my files in a table ? But if so, how can I import a column with more than 8000 characters ?
Thank you in advance.
Stored Procedure Sizes In Terms Of Lines Of Code ?
Sep 8, 2005First and foremost, thanks for reading and responding!Does it matter how big a stored procedure is if you do things in the stored procedure such as:declare the parametersIF @Parm_Select = '<ALL>'do a select IF @Parm_Select <> '<ALL> and @Parm_Report = '1'do a selectIF @Parm_Select <> '<ALL> and @Parm_Report = '2'do select This goes on and on and on and I have written a couple of stored procedures that are about 1500 lines of code based upon parameters passed I do not create any tables - they are just all select statements based upon the parameters passed.I thought I was doing the right thing cause I did not want to have to write a procedure that called a procedure, (I read this and got confused on the return prarmeters cause there is a lot of data being returned from the select ----- I don't think I said that correctly! . I am just learning this SQL stuff and I it is cool and I am excited - but I don't want to develop any bad habits in the beginning - and I try to look these things up on the www - but I just don't get explicit answers from reading all of this stuff. Thank to all in advance!

How To Get Date Difference In Terms Of Year,month,days
Mar 31, 2008
I am using oracle 10G DB as back end.I have two date fields in a table.
1)premium_paying_start_date
2)premium_paying_end_date
i have to get the premium_term i.e, the difference between the two dates(premium_paying_end_date-premium_paying_start_date).
The difference should show the year,month and no of days difference.
For example :
premium_paying_start_date : 14-10-1984
premium_paying_end_date : 01-03-2008
Difference should be : 23 Y : 4 M : 15 D (Y = years, M = months , D= days)
So please give me the solution for this.
SQL 2000 MS Search: Boolean Search Doesn't Work When Search By Phrase
Aug 9, 2006I'm just wonder if this is a bug in MS Search or am I doing something wrong.
I have a query below
declare @search_clause varchar(255)
set @Search_Clause = ' "hepatitis b" and "hepatocellular carcinoma"'
select * from results
where contains(finding,@search_clause)
I don't get the correct result at all.
If I change my search_clause to "hepatitis" and "hepatocellular carcinoma -- without the "b"
then i get the correct result.
It seems MS Search doesn't like the phrase contain one letter or some sort or is it a know bug?
Anyone know?
Thanks
How To Find Terms In A File Name: Regular Expression OR A String Function
Oct 15, 2007hi,
i am using a forEach look to import each file within a folder, but i also need to calculate the dataset related ot these files.
the file are named as:
ff_inbound_20071008_1.csv
ff_inbound_20071008_2.csv
where for file ff_inbound_20071008_1.csv:
ff => flat file
inbound => dataset of this csv
20071008 => date
1=> file count
having in mind that they are store in the variable as a full path:
z:myFlatFilesexportsproj01ff_inbound_20071008_2.csv
i need to extract the dataset and the date for each file.
how can i extract these terms from the file name?
many thanks,

Cached Datasets?
Aug 8, 2007Hello all,
I have a report with a table and a chart. It uses dataset1 as the data source.
All works fine.
I create a new dataset called dataset2.
The queries are exactly the same. The only differences between the 2 datasets is the database server and the fact that one of the columns is a smallint (in dataset2) and an int(in Dataset1)
I change the datasetName property of both the table and the chart to use dataset2.
When I run the report I get a conversion error stating that there was an overflow of int2 while using dataset1. I have verified the report is not using dataset1 anywhere. If I delete dataset1 and run the report the error goes away. If I add it back, I get the error again. Why is the report looking at dataset1 if it is not referenced at all in the report? Does SQL RS cache the datasets and verify each when it compiles?
regards,
Bill
View Result Cached
Aug 1, 2007I am using SQL server 2005. I have a VIEW that joins several tables. One of the table's column can be added dynamically by the user from a GUI interface. However, after a column is added, it does not show up in the VIEW immediately. It will take a while (I haven't figured out exactly how long) before the extra column shows up as the execution result of the VIEW.
So it seems like SQL server is caching that VIEW's schema. Is there anyway I can make this view always comes back with the latest schema?
Thanks a lot!

Non-cached Lookup Method
May 28, 2008Phil, great links, really helpful and appreciated.
I just need to verify one thing on the lookup method:
--One of the lookup methods people were discussing is non-cached lookup -- which seem to be evaluated to be the fastest. Is the non-cached the default of LookUp transformation? and when I wanted the lookup method to be cached, I need to go into the Advance tab and set it to however %, right? thanks.
Snapshot And Cached Instances
Oct 23, 2007Hi,
I'm trying to understand the cases where it's more interesting to use snapshot and when it's more interesting to use cached instances.
If I have 100 users trying to reach a report, is it better to use snaphsot or cache instance ? In both case, the 100 users will have the same report result. And what about the performance, are they similar ?
Thanks for your time and response,
See you,
Have a nice day!

Snapshots Vs Cached Instances
Jun 19, 2007Hello,
I would like to know what is the difference between a snapshot and a cached instance in SSRS?
Which one has the best performances and which one is the best for multiple users and reports containing parameters (the parameters are then passed in the where clause of the sql code; ex: WHERE IN(@param1))?
Thanks for your answers.

Too Many Stored Procedures Or Cached Plans?
Aug 16, 2005I was wondering if anyone had an concrete information about if there is a problem with having too many stored procedures or plans in the cache? Obviously there is an impact on memory but if we can ignore that for the time being, does SQL perform just as well with 100 query plans as it does with 10's millions of plans?
View 9 Replies View RelatedKeeping A Cached Lookup In Memory
Dec 10, 2007Is it possible to keep a Cached Lookup in memory when executing multiple Data Flows? Executing DFT€™s in parallel will cache and use the same LOOKUP statement. But what if I€™m executing the DFT sequentially, can I keep the LOOKUP from the first DFT in memory for the second DFT? For example, in my case, I€™m caching a lookup against the Customer dimension for invoices. The second DFT then processes credits and again does a lookup against the Customer dimension. I want to use the cached Customer records from the first DFT.

View 7 Replies View RelatedFull Cached Lookup With Parameters
Jul 8, 2006Parameterized queries are only allowed on partial or none cache style lookup transforms, not 'full' ones. Is there some "trick" to parameterizing a full cache lookup, or should the join simply be done at the source, obviating the need for a full cache lookup at all (other suggestion certainly welcome)
More particularly, I'd like to use the lookup transform in a surrogate key pipeline. However, the dimension is large (900 million rows), so its would be useful to restrict the lookup transform's cache by a join to the source.
For example:
Source query is: select a,b,c from t where z=@filter (20,000 rows)
Lookup transform query: select surrogate_key,business_key from dimension (900 M rows, not tenable)
Ideal Lookup transform query:
select distinct surrogate_key
,business_key
from dimension d inner join
t on d.business_key = t.c
where t.z = @filter
Linked Servers And Cached Execution Path
May 1, 2006I have a procedure that generates dynamic sql and then executes via the execute(strSQL) syntax. BOL states that if I use sp_executesql with hard-typed parameters passed in variables, the query optimizer will 'probably' match the sql statement with the cached execution path, thus avoiding recompilation and speeding up the results for heavily run procedures.
Can anyone tell me if this is also true if the sql references an object on a linked sql server 2000 database? Technically, the sql is exactly the same, but I'm unsure if there is some exception due to the way linked objects are processed.
Thanks!
SQL 2012 :: Way To Invalidate Cached Query Plans?
Apr 29, 2014Any way to invalidate cached query plans? I would rather target a specific query instead of invalidating all of them. Also any sql server setting that will cause cached query plans to invalidate even though only one character in the queries has changed?
exec sp_executesql N'select
cast(5 as int) as DisplaySequence,
mt.Description + '' '' + ct.Description as Source,
c.FirstName + '' '' + c.LastName as Name,
cus.CustomerNumber Code,
c.companyname as "Company Name",
a.Address1,
a.Address2,
[code]....
In this query we have seen (on some databases) simply changing ‘@CustomerId int',@CustomerId=1065’ too ‘@customerId int',@customerId=1065’ fixed the a speed problem….just changed the case on the Customer bind parameter. On other servers this has no effect.the server is using an old cached query plan, but don’t know for sure.
Images Not Displaying From Snapshot Or Cached Report
Apr 11, 2008Hello,
This is my first post, and I'm hoping you all can help.
Using Reporting Services 2005, I have several reports that use embedded images.
All images render fine when the report execution is set to:
1) Always run this report with the most recent data
1a) Do not cache temporary copies of this report
However, when I change the execution to either a Cache or a Snapshot, the images and some charts render as red "X" placeholders. This is sometimes remedied when the user clicks the page refresh button, but not always.
Of course, I could just have all the concurrent users use the uncached report that hits the OLAP server, but that would be highly inefficient, and just plain slow.
Thanks for any help on this subject.

Clear Cached Reports In Visual Studio
Jun 12, 2007I am frequently going back and forth between the making changes to my reports and previewing those changes, all from within visual studio without publishing the reports each time.
The problem is that frequently changes that I make are not reflected in the preview window unless I either close out of visual studio completely or I wait some length of time, (I'm not sure how long exactly, but 1/2 an hour seems to always do the trick.)
Is there a way to clear any cache and force visual studio to completely reprocess a report?
At least when it is formatting changes I can identify whether the change has stuck, but when I'm fixing bugs in the code, I can't tell if I didn't fix it or if the change just hasn't taken effect.
Storing Daily Cached Query Results In SQL Server
Mar 7, 2005I'm working on a reporting tool that could bring back hundreds of thousands of results back at once. I need some way to run the actual query only once a day, and then the reporting tool would just pull back this cached results. To be short, I need to figure out how to do this using a minimum amount of resources. Would a DataView work with something like this? How would I have it update only once a day? I appreciate any advice!
View 2 Replies View RelatedSQL 2012 :: Entity Framework Returning Cached Data
Mar 23, 2014I have a datagridview bound to a table that is part of an Entity Framework model. A user can edit data in the datagridview and save the changes back to SQL. But, there is a stored procedure that can also change the data, in SQL, not in the datagridview. When I try to "refresh" the datagridview the linq query always returned the older cached data. Here's the code that I have tried using to force EF to pull retrieve new data:
// now refresh the maintenance datagridview data source
using (var context = new spdwEntities())
{
var maintData =
from o in spdwContext.MR_EquipmentCheck
where o.ProdDate == editDate
orderby o.Caster, o.Strand
select o;
mnt_DGV.DataSource = maintData;
}
When I debug, I can see that the SQL table has the updated data in it, but when this snippet of code runs, maintData has the old data in it.

Auto Stats Adversly Affect Cached Plans?
May 31, 2007With SQL2005 SP2, we are seeing that when auto stats run on one or more indexes of a large table (1.5M rows), then immediately the stored proc using that table starts acting as if the query plan is no longer any good. This causes a drastic slowdown in response time and a corresponding increase of table reads to get the data. E.g, the next execution of the procedure after the auto stats kick in goes from 355 reads to 755000 reads (as depicted by Profiler). Generally, there are about 25 people using the DB at any one time. They connect through a mid-tier VB component.
I tried adding WITH RECOMPILE to the stored proc in question, but that caused almost all executions to run at the higher number. I thought that the WITH RECOMPILE hint would create a new query plan for each execution of the procedure and that plan would the the latest and greatest. Perhaps it did, but most users got stuck with the higher number of reads anyway. After taking the hint out, everyone went back to getting the 335 number and quick response times.
What we are wrestling with is that when those auto stats hit, it really messes up everyone until we manually recompile the procedure. Daily we delete all records in the table that are over 45 days old, so the table stays pretty much the same size. We also set the recompile flag to cause a new plan to be generated that will reflect the smaller amount of data. Should we also run a stats update before recompiling the procedure? Profiler has been very helpful in capturing what is going on, so I think I have a good handle on that. However, I don't understand why WITH RECOMPILE produced a messed up plan for everyone. The compile itself seems to take only 1 ms when done from the query screen.
Reporting Services :: SSRS 2008 R2 BIS Deploy Does Not Always Clear Cached Reports

Is there a workaround, fix, process change, configuration change I can do to keep this from happening?
