i'm creating a sql hoilday database and i need to write a sequence but i've been told its wrong but i dont know why, can anyone help?
CREATE SEQUENCE SEQ_HOILDAY_SITES
INSERT INTO Details_of_sites_visited(Code_of_the_sites, Sites_name)
VALUES(SEQ_HOILDAY_SITES.NEXTVAL,'124','Yosemite National Park');

Im doing a quickie Access Project for a Fileroom orginization DB. Generally, Records are addressed by a 7 character unique ID, with all sorts of rules, assigned by another system. However we need to track Items that for various reasons do not exist in that system. For this, we enter a code that consists of 2 characters of invalid data, followed by a simple incrementing number. In Oracle, i would do this with a Sequence. How do I go about this in Sql Server?basicly, I want to write a trigger that says something like: pseudo code wrote:before insert: if :new.ItemType is Type3 Then-- File local to our file room :new.FileID = "IV" + getNextLocalNumber().ToString() end ifNote that the fileID is not a Key in the normal DB Sense. It is a neumonicly unique identifier w/ some other properties so that people can easily look things up.
there is this little dumb thing i don't manage to understand about sequences when i create a table i put the id as the primary key and write something like this
Code Block[Id] [int] IDENTITY(1,1) NOT NULL,
so each time the sequence is incremented by,
but if i delete a line from a table and then insert a new one instead of inserting the id 3 for example it inserts id = 4
What is the escape sequence in a stored procedure?
Here is what I'm trying to achieve:
ALTER PROCEDURE Test ( @Func VarChar(1000) )
AS DECLARE @SQL VarChar(8000) SELECT @SQL = 'SELECT DISTINCT TNAME FROM TABLE WHERE FUNC LIKE ' + @Func
Now, my goal is to add single quote (') before @Func and another one after that. For eg, if @Func is "Test", I want my query to be SELECT DISTINCT TNAME FROM TABLE WHERE FUNC LIKE 'Test'
and NOT SELECT DISTINCT TNAME FROM TABLE WHERE FUNC LIKE Test
I have to identify missing records from the example below.
Category BatchNo TransactionNo
CAT1 1 1
CAT1 1 2
CAT1 2 3
CAT1 2 4
CAT1 2 5
CAT1 3 6
CAT1 3 7
CAT1 3 8
CAT1 5 12
CAT1 5 13
CAT1 5 14
CAT1 5 15
CAT1 7 18
CAT2 1 1
CAT2 1 2
CAT2 3 6
CAT2 3 7
CAT2 3 8
CAT2 3 9
CAT2 4 10
CAT2 4 11
CAT2 4 12
CAT2 6 14
I need a script that will identify missing records as below
Category BatchNo
CAT1 4
CAT1 6
CAT2 2
CAT2 5
I do not need to know that CAT1 8 and CAT2 7 are not there as they potentially have not been inserted yet.
I idealy want a nice clean SQL statement and do not particually want to insert new table's or triggers although views i Can deal with to an extent.
Considerations up to 50,000 records added per day!!! Only need script to run once a day and I have insert dates to help me. Only 12 Categorys Batch numbers always start at 1 for different categorys
I would like to use sequences and triggers to update table identity field with int value from sequence via before insert trigger. I'm searching on google for a few days and there are no same or identical article about this subject.
Is there any sample how to create table with column Id, Name, Comment and sequence (for generate int numbers for Int field in table) and trigger which will fired before insert and check is inserted Id is NULL and update this field from sequence or nothing if id is set up.
I am working on a text mining application wherein I need to detect unusual/anomalous sentences in text. Certain sentences, that I know occur very frequently, are given a likelihood of 0.2 by PredictCaseLikelihood. Other sentences that are just as frequent get a much higher likelihood (>0.9). I am using the NORMALIZED option. The only significant difference between these sentences is their length. The one with the lower likelihood has only 2 words in it, whereas the one with the higher likelihood has more than 10 words. The problem is that the shorter sentences end up being interpreted as anomalous, when in fact they are'nt. Any suggestions?
I've seen several posts about reading and writing files that have different record types with varying column metadata. My particular file has 11 record types plus several header types and looks something like:
<Header1>
<Header2>
<Detail01-#1>
<Subdetail02>
<Subdetail03>
...
<Detail01-#2>
<Subdetail02>
<Subdetail03>
...
...
Since i need to get different detail and subdetail records, i can't really use the technique of 3 dest file connection managers found in http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=87269&SiteID=1
I've tried using an exec sql to get the main detail records and then a forech ADO en umerator that would get the subdetails, but it all seems so kludgy. I'm starting to think that I should just write the bulk of the file creation code in a c# app instead of trying to smush this into SSIS. Opinions? Am I missing some trick in SSIS?
