Hi all,
I am dealing with a very large database, and as soon as a record is
submitted I need to run a full-text query against it. I believe it
might take a while before the record is fully indexed and therefore
would not return a result.
How can I check whether the record in question is already indexed, if
at all?
This is MS SQL 2005
Thanks in advance..
How can (is full-text indexed) property TRUE in column properties in moment create table with right-click on tables and select NEW TABLE?
View 1 Replies View RelatedHi,
I have problem that Im sure others must have had before so I am looking for advice on the best way to solve it. I have a table of text information tbl_base which is related to another table containing tags, which can contain several rows for each row in base.
I want to create an indexed view of the data for full text search. I would like to select all the tags related to a particular row in the tbl_base together into a string and join it to the end of the tbl_base table so they can be indexed along with the tbl_base data for full text indexing. Ive tried several methods but I am never able to make an index on my view because it say I cant use COALESCE, or Cursors.
Sample data here :
tbl_base
id | Text
------------------------
1 | BLah blah
2 | Dum de dum
3 | HAr HAr
tbl_base_tags
tagID | base_id | TagText
--------------------------
1 | 1 | first
2 | 1 | second
3 | 1 | third
4 | 2 | fourth
The view I want to end up with will look like this :
vw_tables
base_id | Text | Tags
-------------------------------------
1 | Blah blah | first second third
2 | dum de dum | fourth
How can I achieve this? Do I have to index all the tables seperately?
I'm currently developing a C# Winforms Application that is using FTS on SQL Server. But the documents that I add into the database are not getting indexed. Meaning I can search for what ever I want but not getting any documents back from the sql server. I've made a Full Text Catalog on the desired table and did a full population but nothing happens.Why are the documents that I add into the Database not searchable?How can I index the documents on insert?
View 5 Replies View RelatedI'm creating Indexed view by JOINING multiple tables and trying to create FULL TEXT search index. Unique column is generated by concatenating to ID columns from different table. I can successfully able to create unique index however when trying to create FULLTEXT INDEX getting below error.
"A full-text search key must be a unique, non-nullable, single-column index which is not offline, is not defined on a non-deterministic or imprecise nonpersisted computed column, does not have a filter, and has maximum size of 900 bytes. Choose another index for the full-text key."
The message clearly says the column should be single-column index, non-deterministic.
I have written this sample query to search a full-text indexed table and return the results. If the word occurs more than once I want it to return as a new record and the results show a short summary of the location. I was using 'like', but the full table scans were really slowing it down. Can performance be improved for the following (The results returned by my query are accurate)
Query
DECLARE @searchString nvarchar(255);
DECLARE @searchStringWild nvarchar(275);
SET @searchString = 'first';
SET @searchStringWild = UPPER('"' +@searchString+ '*"');
SELECT id, '...' + SUBSTRING(searchResults.MatchedCell, searchResults.StartPosition, searchResults.EndPosition - searchResults.StartPosition) + '...' as Result

I have a problem with inserting records into table when an indexed viewis based on it.Table has text field (without it there is no problem, but I need it).Here is a sample code:USE testGOCREATE TABLE dbo.aTable ([id] INT NOT NULL, [text] TEXT NOT NULL)GOCREATE VIEW dbo.aViewWITH SCHEMABINDING ASSELECT [id], CAST([text] AS VARCHAR(8000)) [text]FROM dbo.aTableGOCREATE TRIGGER dbo.aTrigger ON dbo.aView INSTEAD OF INSERTASBEGININSERT INTO aTableSELECT [id], [text]FROM insertedENDGODo the insert into aTable (also through aView).INSERT INTO dbo.aTable VALUES (1, 'a')INSERT INTO dbo.aView VALUES (2, 'b')Still do not have any problem. But when I need index on viewCREATE UNIQUE CLUSTERED INDEX [id] ON dbo.aView ([id])GOI get following error while inserting record into aTable:-- Server: Msg 8626, Level 16, State 1, Procedure aTrigger, Line 4-- Only text pointers are allowed in work tables, never text, ntext, orimage columns. The query processor produced a query plan that requireda text, ntext, or image column in a work table.Does anyone know what causes the error?

I have two database in the sql server and consider that i have a query which has 4 tables inner joined.
When i execute the query in the database1 , the query is returning rows, But when i execute the same query in the database2, the query is not retuning rows . I know that the
no rows are returned because of missing data in the database2. But have no idea how to trace what values are missing in the database2. Please note the tables is having a huge
list of records by which manually comparison is painfull. Please consider i dont have any background idea of the values in the tables but just using it. Any help would be
appericated.
I have created a table from another table where I specified that one of the fields, an number field, is sorted in ascending order and have NOT specified that it is to be an indexed field and there are 10 million records, from 1 to 10,000,000 exactly.
Now, if I query that table, asking to return records 1-1,000 from that non indexed number field that I sorted in ascending order (where number field <= 1,000) , will it run as fast as if it were indexed?
In other words, does SQL know somehow that these records are sorted in ascending order and so will not do a full table scan, stopping at 1,000 to return my data set?
Or is there no way for SQL to know this and only specifying an indexed field allows SQL to know that its in some order and so it doesn't have to do the full scan?
Hi, i'm trying to do a full text search on my site to add a weighting score to my results. I have the following database structure:
Documents: - DocumentID (int, PK) - Title (varchar) - Content (text) - CategoryID (int, FK)
Categories: - CategoryID (int, PK) - CategoryName (varchar)
I need to create a full text index which searches the Title, Content and CategoryName fields. I figured since i needed to search the CategoryName field i would create an indexed view. I tried to execute the following query:
CREATE VIEW vw_DocumentsWITH SCHEMABINDING ASSELECT dbo.Documents.DocumentID, dbo.Documents.Title, dbo.Documents.[Content], dbo.Documents.CategoryID, dbo.Categories.CategoryNameFROM dbo.Categories INNER JOIN dbo.Documents ON dbo.Categories.CategoryID = dbo.Documents.CategoryID
GOCREATE UNIQUE CLUSTERED INDEX vw_DocumentsIndexON vw_Documents(DocumentID)
But this gave me the error:
Cannot create index on view 'dbname.dbo.vw_Documents'. It contains text, ntext, image or xml columns.
I tried converting the Content to a varchar(max) within my view but it still didn't like.
Appreciate if someone can tell me how this can be done as surely what i'm trying to do is not ground breaking.
Hello everyone !
I want to perform Full Text Search with SQL Server 2000. My documents (.doc, .xls, .txt, .pdf) are stored in a SQL Server field which is binary (the type of the column is image).
I would like to know, how you can extract pieces of text from the documents.
Example:
I have a ASPX page with codebehind in C# making the search in a table in SQL server that is full text indexed.
I make a search looking for the word "peace", than SQL server will take care about the search and return it to me the rows that match with that. But also I'd like to extract the 50 characters before and after where sql server found the word "peace" to show in the result page.
Does anyone has any idea how to work around it ?
Best regards.

Hi,
Can someone please tell me the best practices for checking the primary key field before inserting a record into my database?
As an example I have created an asp.net page using VB with an SQL server database. The web page will just insert two fields into a table (Name & Surname into the Names table). The primary key or the Names table is "Name". When I click the Submit button I would like to check to ensure there is not a duplicate primary key. If there is return a user friendly message i.e. A record already exisits, if there no duplicate, add the record.
I guess I could use try, catch within the .APSX page or would a stored procedure be better?
Thanks

Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey

Any idea?

How to check if a record is already in the database I want to import to before importing?
My table have 2 primary key, and the DTS is suppose to be schedule to run every night, though it can be run whenever a user want to get the most updated data.
Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey
1 2 Null
2 8 1
8 5 2
5 null 8
Ex : In the first record of the table, the NextKey is pointing to 2.
So the next record of Skey will be 2. The Next Key for this record is 8. Like wise the next record of this should have the Skey as 8.
Now I need to check whether the NextKey and SKey are correct for all rows.
For that I need to check the previous record of "Next key" and next record of "Skey".
Any idea?

Is there a t-sql shortcut/ quick way to return the full max record.
So basically if I had:
prog_area glh description
HS 200 health and social care
EN 300 engineering
HS 400 health care
EN 250 engineering and construction
so grouping by prog_area and taking max glh would return appropriate descriptions like:
HS 400 health care
EN 300 engineering
This is quite a simple example and I would be using it on much larger datasets. I know how to do it by doing a join to itself with max glh but it seems to me there should be an easier way to return the appropriate full record set. Hopefully somethin fast in t-sql
I am using the tables created by the aspnet_regsql.exe tool for security. Basically, I need to ensure that an account named Administrator is never deleted. I also have a role named administrator, and I need to make sure that Administrator is never removed from the administrator role.Can I create a trigger to ensure that the Administrator is never deleted and that the Administrator is never removed from the Administrator role? I know it will probably be two separate triggers: one on the aspnet_users table and one on the aspnet_usersinroles table.Thanks a lot for the help!

I am setting up Availability Groups and I want to use the secondary replica to perform the full copy_only backups to reduce the load on the primary replica.But what is the best way to check for successful full backups on Availability Group databases?
Previously I could check the system table msdb.dbo.backupset but this is not available for copy_only backups.So I wonder how people are monitoring that their full backups have been successful?
Do you just check that the SQL Agent job that runs the backup was successful?
Or do you search the SQL Server Error Log for entries like "Database backed up. Database: xxx" where database xxx is in an Availability Group?
Or is there a better method?

Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field.

Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?
