T-SQL (SS2K8) :: Search For A String In Expression By Number Of Its Appearance - Charindex
Apr 3, 2015
I have written a query to search for a string in an expression by the number of it's appearance. Script is like this:
DECLARE @Expression VARCHAR(8000) = 'abcd_e_fgh',
@SearchString VARCHAR(10)= '_',
@OccuranceNumber SMALLINT = 1
DECLARE @SearchIndex INT = 0, @SearchIndexPrevious INT = 0, @Sno INT = 0
WHILE @Sno < @OccuranceNumber BEGIN
[Code] .....
Here i'm trying to search "_" in expression "abcd_e_fgh" where it is appearing for first time. it gives me 5 correctly. Now when i change the @OccurenceNumber to 2 or 3, it gives correct values 7 and -1 respectively. However now when i change it to 4, it gives me 5. So when it's trying to check for fifth appearance of "_", it's not actually giving 0 or -1 but repeating the value 5.
I have a column that contains the follwoing string I need to compare.
ek/df/cv/ ek/df/cv/f
All fields bfore the third / are not fixed but behind the third/ is eiter nothing or one letter I need a function to extract all the fields before the third / to compare if they are equal.
I can't do it by using the combination of Substring() and charindex() and Len()
select top 5000 textdata,substring(textdata,charindex('exec',textdata)+5,charindex('@',textdata)-1) from trace_table where TextData like '%sp_%' and TextData like '%declare%'
In t-sql 2008 r2, I would like to know how to select a specific string in a varchar(50) field. The field in question is called 'CalendarId'.
This field can contain values like:
xxIN187 13-14 W Elem HS321 13-14 D Elem IN636 13-14 C Elem 030 13-14 clark middle.
What I am looking for is the first position that contains a number value for the length of 3. Thus what I want are values that look like the following: 030, 636, 187.What I know that I want is substring(CalendarId,?,3).The question mark is where I want the starting location of a number value (0 to 9) of the value in CalendarId . I tried pathindex but my syntax did not work.
HelloI am quite hopeless and of course a newbe.The situation: Sql2k / queryI would like it ot break down the following string:2004 Inventory:Ex.Plant Farm1:1st Cut:Premium:0094Whereby:Year = '2004 Inventory'plant= 'Ex.Plant Farm1'cut = '1st Cut'grade = 'Premium'lot# = '0094'It is always seperate by ':', but it can be 5 fields or 4 or 3 and sooncode to create the view:CREATE VIEW dbo.TESTASSELECT FullName, LEFT(FullName, CHARINDEX(':', FullName + ':') -1) AS year, CASE WHEN LEN(FullName) - LEN(REPLACE(FullName, ':', ''))[color=blue]> 0 THEN LTRIM(SUBSTRING(FullName,[/color]CHARINDEX(':', FullName) + 1, CHARINDEX(':', FullName + ':',CHARINDEX(':', Fullname) + 1) - CHARINDEX(':',FullName) - 1)) ELSE NULL END AS Plant, CASEWHEN LEN(FullName) - LEN(REPLACE(FullName, ':', '')) > 1 THENLTRIM(SUBSTRING(FullName,CHARINDEX(':', FullName + ':', CHARINDEX(':',FullName) + 1) + 1, CHARINDEX(':', FullName + ':', CHARINDEX(':',Fullname) + 1) - CHARINDEX(':',FullName+':') - 1)) ELSE NULL END AS [Cut]FROM dbo.ItemInventoryCan anyone help me with this? I am stuck half the way and get for cutthe rest of the string: '1st Cut:Premium:0094'Thanks!
I've the following query. I'm using the yellow highlighted to join 2 tables, as these tables dont have a relationship between them. The format of the name field is 'AAAA-BBBBBB-123' here A will be only 4 chars, followed by '-' B can be any number of chars again followed by '-' and the last is the id which I'm using to do a join. This query will fail if the id is just 1 digit as its taking the last 3 chars as the id. I dont know how to get the id from the right using charindex. Charindex would search for the first occurence of '-' from the right and get the chars after hypen i.e 123. How can this be achieved?
SELECT id AS 'ID', name AS 'name', sequence AS 'num' FROM FirstTable A INNER JOIN SecondTable q ON (CONVERT(INT,RIGHT(name,3))= a.id) INNER JOIN ThridTable t ON(t.id = q.id) INNER JOIN FourthTable s ON (q.name = s.name ) WHERE A.id = @ID AND t.name=LEFT(s.name,((CHARINDEX('-',s.name))-1)) ORDER BY 'ID','num'
One more question on this is: Is this a good way of joining tables? If I dont use this I've a very large query containing unions. Which one should be bug-free and more efficient?
I am trying to erase some erroneous bad data in my table. The description column has a lot of </div>oqwiroiweuru</a> weird data attached to it, i want to keep the data to the left of where the </div> erroneous data begins
update MyTable set Description = LEFT(Description(CHARINDEX('<',Description)-1)) where myid = 1
that totally works.
update MyTable set Description = LEFT(Description(CHARINDEX('<',Description)-1)) where myid >= 2
gives me a Invalid length parameter passed to the LEFT or SUBSTRING function. The statement has been terminated error.
I have a scenario where in I need to use a comma delimited string as input. And search the tables with each and every string in the comma delimited string.
Yep, I know this will have been asked before (because I've seen it), but I can't for the life of me find a thread!
So I've inherited this database and I need to search the whole darn thing for a single word, returning something lovely, like the table or column the thing resides in. Basically it's a code in one of 100+ code tables, all with inconsistant, unclear naming - YAY!
FYI, I'm using SQL Server 200 and the word I'm looking for is "Unpaid".
I have been trying to calculate age and the results either round the age up one year or down one year. I have tried CASE, DATEDIFF, FLOOR functions but nothing works.
I have a text field which has entries of variable length of the form:
"house:app.apx&resultid=1234,clientip" or "tost:app.apx&resultid=123,clientip" or "airplane:app.apx&resultid=123489,clientip"
I'm trying to pick out the numbers between resultid='...',clientip no matter what the rest of the string looks like. So in this example it would be the numbers:
1234 123 12389
the part of the string of the form resultid='...',clientip always stays the same except the length of the number can vary.
I am loading data from an iseries into a sql server 2005 DB. Our dates are stored as a numeric value in a format of CYYMMDD where C = Century indicator 20'th is 0 and 21'st is 1, YY = Year, MM = Month and DD = Day!
Today would be 1070701. Now I want to use a derived column which which would be of type date using an expression to do the conversion.
Usually, we would add 19000000 to the number to give us 20070701 then I'd convert it to a string and then substring into a date format.
I'm just getting started with SQL 2005 so I don't know how to do this using an expression.
One of my measures is in seconds and I would like to convert it to hours.
It is simply a number in decimal format
the expression I tried is this [Measures].[OPEN DURATION] /60
and I ge this message Error 1 Errors in the metadata manager. The measure expression of the OPEN DURATION measure contains the [(60)] operand , which could not be resolved. 0 0
All help is appreciated, thank you in advance. I have tried a couple different syntax's with no luck.
I am a newbie to SSIS and looking for answer to a simple search/replace style question.
I am building a derived column and looking for some expression syntax that can search for several strings in one column and set a value in a new column.
A bit like a case statement:
CASE ProductLine WHEN 'R1' THEN 'Road' WHEN 'M1' THEN 'Mountain' WHEN 'T1' THEN 'Touring' WHEN 'S1' THEN 'Other sale items' ELSE 'Not for sale' END,
The twist is that 'R1','M1','T1','S1' could feature anywhere in the string that is ProductLine.
In my sql statement, I don't have any datatype as INT, when I run it, give me error as 'Arithmetic overflow error converting expression to data type int'.
example : select column1, 2, 3 ..... from (select sum(float) as column1 , ....)
When I hop my cursor on top of column1, it shows (int,null)
I need to search all tables in my user database to find a value. I don't know what the column name is.
I know of one table that contains the value, but I need to look through all the tables and all there columns to see if I can find if this value exists in more than one place. It is an int value - 394789.
I have a table which has expression as a column and the data looks similar to the following .
ID (int) Expression (nvarchar data type)
1 8*(1/2)-6
2 278*(1/4)-2
3 81*(3/5) +4
I now have the expression as an nvarchar. (Ex: 8*(1/2)-6)
Now I need to evaluate this expression and output the result (which is -2 in above Ex) .Can someone give me idea on how do I evaluate the expression which is available as a string. I need to write a procedure for this.
I am unable to cast/convert nvarchar to float/int
Any sample code would be greatly appreciated.
This a very urgent requirement for me.Please get back
Select * from TableName Where Contains(ColumnToBeSearched, 'testtosearch')
QUESTION: Can the 'testtosearch' be another table field like ''' + <AnotherTBLField> + '''Is there anyway to make the population of 'testtosearch' to be based on another table field (say when you join to it)?If not what else can I do, another function maybe?
I am looking for some syntax to help me with a traditional search/replace style requirement. I am wanting to examine the contents of one column and populate another.
similar to this SQL case statement
CASE ProductLine WHEN 'R1' THEN 'Road' WHEN 'M1' THEN 'Mountain' WHEN 'T1' THEN 'Touring' WHEN 'S2' THEN 'Other sale items' ELSE 'Not for sale' END,
the twist is that R1, M1 etc. can appear anywhere in the ProductLine column.
I can't figure this one out. I don't have enough knowledge of the string functions I guess.
I need to pull a value out of a variable I setup in a for each loop. The value is the filename/path of each source file being processed. Let's say the variable that has the source file path is called VAR1.
One sort of off topic thing I've noticed is when watch the variable in bebug mode and I look at the value of VAR1 it has double back slashes. Here's an example of the value of VAR1:
"\\L3KRZR6.na.xerox.net\C$\Documents and Settings\ca051731\Desktop\Project4\DPT_20070926.ver"
How come the back slashes have been doubled? And do I need to account for that when I start parsing the string value?
Anyway, I need to grab part of the filename from VAR1 and I need the value populated at the start of the for each loop container - ideally when I capture VAR1 in the for each container. I'll be using the string in drop table, create table and create index statements before the actual Data Flow task within the overall package
In the above example I need to grab the characters before the underscore and after the last \. So I'd need the string "DPT" captured in this example.
The actual string could be 1 to 3 characters long, even though this example has it as 3 long.
Underscores could exist anywhere in the actual UNC path once this package is moved to our actual system environments so I can't key off of the underscore.
Because I can't count on the string being a fixed lenght I can't just use a positional string function and grab specific text starting/ending at specific points.
Is there a way to use the various string functions in the expression builder to grab the text between the right most underscore and the right most back slashes or something like that? Ideally I'd like to setup a new expression based packed scope variable called VAR2 and build it using string functions applied to VAR1.
I'm not exactly sure how to phrase this problem. If I'm going about this the wrong way, any pointers would be appreciated.
I am using an expression for a data source connection so I can decide which server/database to use at runtime. I also need to pass credentials to use for that connection. The only way I'm able to get this to work is to specify "No Credentials" for the data source and then pass a DataSourceCredentials to the report throught the report viewer. This works, for the most part, but puts a "Change Credentials" link in the report viewer.
What I think would be much better is if I could specify the credentials in the connection string that I pass. However, everything I've tried so far has not worked. I get errors complaining that the compination of options is invalid or that the report server cannot find the credentials of "unknown keyword: User Name". All by trying various combinations of things.
How do other people go about this? I've seen blogs implying that this is not such a big deal (that credentials CAN be passed over in the connection string). Hopefully I'm missing something simple here. If I have no choice, the "Change Credentials" link will not be the end of the world, but that's very sloppy. The people viewing this report will not know anything about the database credentials and I'd rather not show them somthing as inviting as a link that can get them off track.
I have what should be a simple string formatting issue -- removing all alpha characters from a phone number. T-SQL below is simple and works just fine:
declare @home_phone as char(14); set @home_phone = '(123)979-3206'; set @home_phone = REPLACE(@home_phone,'-',''); set @home_phone = REPLACE(@home_phone,'(',''); set @home_phone = REPLACE(@home_phone,')','');
The condensed version below works equally well:
set @home_phone = REPLACE((REPLACE((REPLACE(@home_phone,'(','')),')','')),'-','');
Either script above returns correct result:
select @home_phone; Result = '1239793206'
HOWEVER, within SSIS Derived Column expressions, this function fails to remove parentheses. First of all, Expression Builder doesn't like outer single quotes (turns red) which I resolved by using double quotes resulting in the following expression:
Unfortunately, this expression fails to remove parentheses and instead returns: '(123)9793206'
I've tried several different permutations--no inner single quotes; adding more inner single quotes; etc., but so far no success. Any suggestions would be much appreciated!
Are the XML tags searched, as well as, the contents within the tags, when an xml column is included in a full-text index? Or is it only the contents within the tags? Would I need to combine full-text search with XPath/XQuery to get at the actual tags?
I'm trying to pull up a report of restored databases from our bug tracking software to audit and see if any of them can be taken down, and having some trouble figuring out how to pull the list of databases out of the entire request text, since they usually come in via email. Some sample data is below with the paltry beginning of a solution that I came up with.
WITH bug (BugID, BugComment) AS ( SELECT 1, 'Hello DB_001000, DB_001000, DB_001000 Blick' UNION ALL SELECT 2, 'Hi DB_001000 DB_001000 DB_001000 DB_001000 Flick' UNION ALL SELECT 3, 'Urgent DB_001000 DB_001000 Glick'
