In the process of resequencing my web items, I am trying to append 4 zeros on the end of each item sequence number. Everything I try does not work, it seems to automatically remove the trailing zeros because of formatting. This is an int field. The only thing I got to work for 1 item as a test was actually doing a replace such as:
update sacatalogitem
set itm_seq = replace(itm_seq, '8021', '80210000')
where itm_id = '13' and ctg_id = '917'
I have tried using a cursor with the replace and it strips the trailing zeros when executing this:
declare #SEQ int
declare #ID int
declare #CTG int
declare cur cursor for
select a.itm_seq, a.itm_id, a.ctg_id from sacatalogitem as a
join saitem as b on b.itm_id = a.itm_id
where a.cat_id = '307' and a.itm_id = '13' and a.ctg_id = '917'
open cur
fetch next from cur into #SEQ,#ID,#CTG
While (##FETCH_STATUS=0)
Begin
Update sacatalogitem
set itm_seq = replace(itm_seq, #SEQ, #SEQ + '0000')
where itm_id = #ID and ctg_id = #CTG
Update saitem
set itm_import_action = 'P'
where itm_id = #ID
fetch next from cur into #SEQ,#ID,#CTG
end
close cur
deallocate cur
This also fails for me:
update sacatalogitem
set itm_seq = itm_seq + '0000'
where itm_id = '13' and ctg_id = '917'
Any help would be appreciated for this small frustrating problem.
If it is an integer field, MULTIPY IT BY 10000.
update sacatalogitem
set itm_seq = itm_seq * 10000
where itm_id = '13' and ctg_id = '917'
You could try
cast(cast (itemsec as varchar) + '0000' as int)
but frankly #VJHill 's answer is neater

I want to post a solution to a interesting problem I was facing in T-SQL.
The problem:
Compare two string fields based on a percent match.
In addition, the two strings may have the words in them translocated.
For example: "Joni Bravo" and "Bravo Joni". These two strings should return a match of 100%, which means that position is not relevant. Few more things worth noting are that this code is made to compare strings that have space as delimiter in them. If the first string doesnt have space the match is set to 100% without actual check. This was not developed, because the strings this function is ment to compare always contain two or more words. Also, it is written on MS SQL Server 2017 if that mathers.
So here is the solution, hope this helps anyone :)

PS: I decided to write it in a user-defined function just for the needs of my project.
This was my first attempt at a SQL function. I wrote it in VB and it works like a charm. When I translated it to SQL Server, it returns not what I expect. What the function is intended to do is to return a percentage match of two strings.
How I expected it to function is this:
accept two strings, compare the two, and based on my rating values, return a percentage of the match value...matchscore/max possiblescore
The length of the larger string is multiplied by 3. This is the max possiblescore.
Go character by character of the first string and find that character in the second string.
If the character is found in the same position in the second string, add three to the matchscore and move on to the next letter.
If the character is found in the second word, but not in the same position, add one to match score and move on to the next character.
If the character is not found in the second string, add nothing and move on to the next character.
Divide the matchscore by the max possiblescore. This returns a decimal value. I read RETURN only returns an integer, so I multiplied the division result by 100.
An example of what I expected is I compare "CAT" to "CART". My expected return is 7/12...0.58. Instead, I get 0. If I compare "CAT" to "CAT", I expect 9/9...1.00. Instead, I get 2.
(Note from 9/17/2014: I appreciate your input. I used what you suggested, and did one more major change, that doesn't affect what I asked about, other than getting the correct final answer is that I got rid of the second While Loop. Instead, I search for #strLetter in #strWord2. If it is found, then, I look to see if it is in the same position in #strWord2 as #strWord1. If it is, then I add 3, if not, I add 1. This sped up the function and made the count accurate.
Here is the code:
CREATE FUNCTION [dbo].[CompareWords]
(#strWord1 VARCHAR(2000), #strWord2 VARCHAR(2000))
RETURNS DECIMAL
AS
BEGIN
SET #strWord1 = UPPER(#strWord1)
SET #strWord2 = UPPER(#strWord2)
DECLARE #intLength INT
IF LEN(#strWord1) >= LEN(#strWord2)
BEGIN
SET #intLength = LEN(#strWord1)
END
ELSE
BEGIN
SET #intLength = LEN(#strWord2)
END
DECLARE #iWordLoop1 INT
DECLARE #iWordLoop2 INT
DECLARE #intWordLoop2 INT
DECLARE #intWordScore INT
DECLARE #intLetterScore INT
SET #intWordScore = 0
SET #intWordLoop2 = Len(#strWord2)
DECLARE #strLetter VARCHAR(1000)
DECLARE #count1 INT
SET #count1 = 0
SET #iWordLoop1 = Len(#strWord1)
WHILE (#count1 < #iWordLoop1)
BEGIN
SET #strLetter = SUBSTRING(#strWord1, #count1+1, 1)
SET #intLetterScore = 0
DECLARE #count2 INT
SET #count2 = 0
SET #iWordLoop2 = Len(#strWord2)
WHILE (#count2 < #iWordLoop2)
BEGIN
If #strLetter = SUBSTRING(#strWord2, #count2+1, 1)
BEGIN
If #iWordLoop1 = #iWordLoop2
BEGIN
SET #intLetterScore = 3
SET #iWordLoop2 = Len(#strWord2)
END
ELSE
BEGIN
SET #intLetterScore = 1
END
END
SET #intWordScore = #intWordScore + #intLetterScore
SET #count2 = (#count2 + 1)
END
SET #count1 = (#count1 + 1)
END
DECLARE #sinScore DEC
SET #sinScore = (#intWordScore / (3 * #intLength)) * 100
RETURN #sinSCore
END;
The most significant changes I made were to
reset the intLetterScore to 0 after it's been used in the intWordScore calculation. Without it being reset, the same value was being used each time the inner loop and the character was not matched.
move the multiplication by 100 into the
brackets in the calculation of sinScore.
As referred to in a previous post, because you are doing integer multiplication, the decimal portion is truncated from the calculation. By growing the wordScore by a factor of 100, it is much more likely to be larger than the length and yield a result which is non-zero.
Multiplying outside the brackets has the multiplies the integer result of the division score by length. If this answer is already zero, then the multiplication result is also zero.
Other changes I made are commented in the code: the variable intWordLoop2 has no effect on the calculation and can be removed; strLetter can be declared as a Char(1) instead of VarChar(1000).

I'm writing a stored procedure and it's working for if but not for else. For if I'm getting the correct ID value but for else it's just giving me null.
SELECT #ID = ID FROM PRODUCTS WHERE SN = #SN
SELECT #Chip_ID = Chip_ID FROM PRODUCTS WHERE SN = #SN
SELECT #Power = Power From Module_Cycle WHERE ChipID = #Chip_ID
SELECT #Test_ID=Test_ID FROM TestEE_Mod WHERE ID=#ID AND #TypeID = TypeID
IF(#Test_ID IS NOT NULL)
BEGIN
IF(#TypeID = '3')
BEGIN
SELECT #Temp_TestID=TestID FROM TempCycle WHERE ChipID = #Chip_ID AND #Power = 'false'
BEGIN
UPDATE TestEE_Mod SET Temp_TestID = #Temp_TestID WHERE ID = #ID AND TypeID = #TypeID
END
END
ELSE
BEGIN
SELECT #Temp_TestID=TestID FROM TempCycle WHERE ChipID = #Chip_ID AND #Power = 'true'
BEGIN
UPDATE TestEE_Mod SET Temp_TestID = #Temp_TestID WHERE ID = #ID AND TypeID = #TypeID
END
END
END
Most likely the issue lies in the #Power variable. In your two SELECT statements, the only difference is that one includes #Power = 'false' in the WHERE clause, while the other includes #Power = 'true'.
Since #Power is a variable, not an actual column in your TempCycle table, I'm guessing you actually meant to filter by Power = #Power in both of them.
I have a SQL Cursor which I'm having issues with. When I remove the IF #debug = 1 statement from inside the cursor, only the first record from the FETCH will get updated but if I leave the IF #debug = 1 all the required records are updated. Any idea as to why this is happening, I know most likely something is wrong with my Cursor? Code is below:

It looked ok to me but i obviously dont have your data to assist. Can I recommend putting a few print statements in various parts of your cursor. That way you can see how the code is actually flowing. It doesnt help but thats what I would do.
Please, can you try to define explicilty both variables: set #ShipmentSKUCount=[initial value],set #ShipmentSKUCountCur=[initial or constant value] and see what will happen?
Also, I found there is no checking for a ##FETCH_STATUS. It may also result into reading same row twice or more.
Please, give a feedback.
I have a column in my database table which has lows of text and lows of rows. In the text, a url needs to be changed for every row. In each row the url can exist more than once.
Can I use the replace function to change all the urls in the text field in my database table without affecting the rest of the text in that same column?
Thanks
Use REPLACE()
UPDATE table SET text = REPLACE(text, 'from', 'to')
Make precise from: like with http://url_from.com/ to http://url_to.com/
