I am using Sql Server 2017 with Transact and a file with synonyms in FTData. I have found several serious flaws and problems but in the Microsoft MSDN forum and in Microsoft connect no one answers me. The rest of the people say they do not know how it works.
Problem 1: Freetexttable Error With More of 3 Words.
I use Freetexttable with thousands of synonyms in a simple query in two Pc. By entering up to 3 words "Microsoft Sql Management Studio" instantly returns the result and the memory remains stable in 6Gb.
If I enter 4 words he is thinking for 10 minutes and the memory consumes until 12Gb. At the start of the video you can see what it takes Sql Server to load the synonyms and every few minutes if Sql Server is not used again it loads them again.
SELECT [Table].*, FT.* FROM [Table] INNER JOIN FREETEXTTABLE([Table], [Contenido], 'Word1 Word2 Word3') FT ON [Table].Id=FT.[Key] WHERE ([Table].STATE IS NULL OR [Table].STATE = ' ') ORDER BY RANK DESC, Page
Problem 2: Transact does not return the inflections of a word if you do not accent it correctly.
When looking for the inflectional of a word, if I introduce the word with the accent the inflections appear well. The server collation is SQL_Latin1_General_CP1_CI_AI
If I introduce the word without the accent, the inflections do not appear. In Spanish café and cafés are accentuated.
When doing the same with the synonyms, returns the same results with or without accent.
SELECT display_term FROM SYS.DM_FTS_PARSER('FORMSOF(THESAURUS, cafe)', 3082, 0, 0)
SELECT display_term FROM SYS.DM_FTS_PARSER('FORMSOF(THESAURUS, café)', 3082, 0, 0)
display_term returns: cafe chicoria sucedaneo mezcla chicoria. In Spanish sucedáneo are accentuated.
Note:After making the video I tried to recover the inflections of the word echaré (with and without accent) and returns the inflections well in both cases. So the problem is with some words.
I have found a very interesting example. I use the verb "echar". Among others, it has 2 inflections that are "echaré" and "echaría". If I consult "echaré" with and without an accent, it works well for me and it also returns me between its inflections.
If I consult "echaría" work well with accent and bad without accent. Video: https://youtu.be/DmfZmzRW4w8
Problem 3: Transact load the synonyms many times.
I have added synonyms and a function that loads them when starting sql server. The problem is that when you make the first consultation you think about 1.5 minutes. Also, if I do not do searches, every so often (it can be 15 minutes) again it seems that it reloads the synonyms, perhaps from tempdb. How is it done to load them once and not delete them from tempdb?
I have this store procedure to load the synonyms at the start of sql server from file:
CREATE PROCEDURE Sinonimos
SET NOCOUNT ON;
EXEC sys.sp_fulltext_load_thesaurus_file 3082, @loadOnlyIfNotLoaded = 1;
Activate the store procedure at startup by:
EXEC sp_procoption @ProcName='Sinonimos', @OptionName = 'startup', @OptionValue = 'on';
Problem 4: You can not protect the synonyms.
I have to install the sql server system on a client but I do not want to leave the .xml file from FTData there with synonyms. Is there a way for the file to load it from a remote URL or can the file be encrypted?
But then I came to the ship weight, which I need to get from PRODUCT_INFO.
I forget the nomemclature for my expression above, so I wasn't able to search possibilities.
Possible to do a quick join off sC into another list?
If possible, I would need a little nudge towards getting it right.
I have a table of products with names and descriptions. So take a word like kneepads. The correct way to spell it is knee pads and the column contains that correct spelling. But users will type in kneepads to search. I solved the plural issue with a custom function that I wrote.
But I'm wondering if I can query the database in Linq, and say something like without removing, replacing a value in the database
from pr in context.PRODUCT_ITEMS
WHERE pr.Name.Replace(" ", "").Contains("kneepad")
Basically I'm just looking for ideas to handle this.
My older program had another table that contains names and descriptions that were pre-stripped for searching and I really don't want to go back to that.
Guess the original idea I had might be the best. A separate table of straight text with no white spaces and just do a join.
Or maybe a table of words with white space that are parsed out with conjunctions removed and verbs fixed.
Hello everybody, i'm writing here because i'm really becoming crazy, i read every kind of internet pages but I'm not able to find a solution but i'm also sure that the solution is behind the corner.
I have an Access database with different tables. The main table has different foreign keys to other tables. I do an example with 2 tables to make the problem easier:
Field1 - Primary Key: Product Code - text
Field2: Description - text
Field3: Product Type - integer
Field1: Primary Key - ID - integer - FK on Field3 of "Table Product"
Field2: Description - Text
Now, I open Visual Studio, I add my database and I drag&drop the table "Product" on my Windows Form as a DatagridView. The wizard create for me, the tableAdapter, bindinsource ecc....
If I start my app the DatagridView is populate with the correct data but in the column "Product Type" I see the number from the PK of the table "ProductTypes" while I'd like to see the Description.
I created a new TableAdapter query that give me the result i want to see but when I confirm I get the message that i'm created a query that give a different result from the original schema. If I continue the query is created but i'm not able to retrieve data using this new query.
THe only way I've to retrieve datas as I want is to modify the original Fill query but in this case the relation between the 2 tables will be removed and also the TableAdapter Insert method will be removed.
So, I will see the data in datagridview as i'd like to see but I don't have anymore the insert method.
Can someone help me by telling I could I retrieve the data in the way I desider without losing the chance to insert new record in the table?
