SQL Pattern Matching
Mar 20, 2008Hi everyone. I'm developing a web search engine using asp and SQL Server 2000. I need to return records that matches with a string entered by users. In example, suppose my database to have this structure and it's filled like this:
ID NAME KEYWORDS
--- ------- -----------
AA025 NAME1 attached, atic, common, business, hotels
AA026 NAME2 headache, medicin, aspirins, heat, health
AA027 NAME3 at, services, music, electronics
suppose that user enters 'at'. By now, i'm using this pattern '%<input_text>%'. So in this example, pattern would be '%at%'. As i remarked in the fields above, the three fields matches, and that's not what i'm looking for. I want that the result of that query be just the last field, with 'AA027' ID.
Thanks in advance guys.
Cheers.
Unicode And Pattern Matching
Mar 30, 2015I've been trying to find and filter out data that can cause FOR XML to fail with the error:FOR XML could not serialize the data for node ?? because it contains a character (0x0006) which is not allowed in XML.I thought it would be simple, just identify the rows that don't match the XML spec URL...
However, the following doesn't work.
select fieldname
from tablename
where fieldname
like N'%[^'+nchar(0x9)+nchar(0xA)+nchar(0xD)+nchar(0x20)+N'-'+nchar(0xD7FF)+N']%'
Not only does this fail to find the offending rows, when I checked by inverted it by taking out the "^" it still returns no rows.When I reduced 0xD7FF down to 0xFF it returns data, but I cannot add the other range back in without all rows not matching.I've experimented with values and found 0x02E9 was the highest I could go without all values vanishing. Even then, numbers lower than that caused a large variation in the number of rows returned.My Field is NVarchar(100) in SQL_Latin1_General_CP1_CI_AS.
Like Pattern Matching - Problem With Param
Mar 19, 2008I've decalred this stored procedure with a simple where and like statement. The problem is I don't see any result.
Here is my code
create procedure sp_Select_ProfileNames
@NameSearch varchar(50)
as
select ProfileFirstName +' '+ ProfileLastName as ProfileName
from Profiles
where ProfileLastName like '%@NameSearch%';
When i change this line:
where ProfileLastName like '%@NameSearch%';
to
where ProfileLastName like '%Bil%';
I see names starting with Bil, but when i enter Bil as param, I don't get anything.
What's wrong here ?
Pattern Matching With Multiple Values
Aug 25, 2006I want to check for multiple patterns in a particular column.
For one pattern I can write e.g.
SELECT * FROM <TablName> WHERE ColumnName LIKE '%abcd%'.
My requirment is to select all rows for which column value matches with many patterns.I will fetch the patterns in a subquery
e.g. (SELECT '%'+name+'%' FROM <TableName>)
Any thoughts?
Pattern Matching Or Find And Replace In SQL Query
Oct 29, 2007I have a table called MessageBoard. It has a column called Messages.
A user can type text including any html tags through a text area ans when he saves it by clicking a button, the content typed by the user is saved in the MessageBoard Table (in the Messages) column. So once saved, the html tags are kept intact. If I have to find and replace certain html tags, what kind of SQL Query I have to write?
For example I want to find all the <pre> </pre> tags and replace it with <p> </p> tags. How do I do this?

Pattern Matching And Full-text Search
Aug 30, 2007I'm not quite sure that this is possible but, I figured that I would check with you experts out there before trying a new approach. I've done quite a bit of research and have not seen anyone quite figure this out yet.
We have a SQL Server 2005 application that stores and indexes documents to the database as an image data type. I'm able to do full-text queries against the documents without any trouble. I begin to run into problems when trying to pattern match social security numbers and drivers licenses stored in a full-text index. I have a user defined function that I call which runs my regular expression that checks for hits of a ssn or license number in the index. I have no problem getting hits when the data sits in a column.
I do need to mention that I have no trouble when searching for a ssn with a fixed value and where I know the ssn (ex: 123-45-6789). I am actually trying to find the existence of the pattern of ###-##-#### (ex: ^d{3}-d{2}-d{4}$) anywhere in the index.
Any help would be very much appreciated.
SQL Server 2012 :: Case Sensitive Pattern Matching?
Dec 20, 2013I have a set of data where a column contains titles which have been formatted as follows:
"FirstWordSecondWordThirdWord...." etc.
That is, all the words have been concatenated but can be visually separated by their capital first letters.
For reporting purposes, I need to break this column into the separate words so that it looks like:
"First Word Second Word Third Word...." etc.
how this can be achieved?
SQL Server 2012 :: Pattern Matching And Data Conversion
Feb 20, 2014I have a table ("MyData") with string columns that have nvarchar data that looks like this:
ColA
--------
42/90
78/109
I plan to do a mathematical grouping on the numerator (eg: 0-10,11-20,21-30, etc... ), So I need to grab the numerator and turn it into an int. For reasons I can't get into, I have to do this in pure T-SQL.
So my question: How would I write a select statement that regex pattern matches "^([0-9]+)/" on ColA and returns integers instead of text?
E.g. THis Query:
SELECT [magic t-sql syntax] as Converted_ColA from MyData
should return this set of int values:
42
78
SQL Server 2008 :: Pattern Matching And Extract Text
Sep 17, 2015I have two tables in SQL Server--an expression table and a translate table.
DECLARE @EXPRTABLE TABLE
(
expression varchar(100)
)
INSERT INTO @EXPRTABLE
SELECT 'CALL("-","","TEST")'
[Code] ....
I am trying to (for lack of a better way to explain it), overlay the pattern onto the expression and extract the text where the "#" symbols are.
So,
CALL("-","","TEST") using pattern CALL("#","#","#") would return -,,TEST
SUB(2,67,TEST,4,) using pattern SUB(2,#,TEST,4,) would return 67
Is Pattern Matching Possible In Derived Columns Expression Syntax?
Feb 8, 2008
Chaps,
apologies for the drip-drip approach......
Is it possible to do pattern matching against a string using FINDSTRING or similar in a derived column expression without recourse to including 3rd party regexp style plugins?
I want to seach for a reference in a string which will have the format ANNNNNAAA ie. an alpha with a certain value followed by 5 digits followed by three alphas with specific values.
eg Z00001YYY or X00022HHH
thanks for your assistance,
regards,
Chris
SQL Server 2012 :: Pattern Matching (positive Across Records - Negative Within A Field)
Jan 6, 2015I am doing some analysis on our customer base and their payment profiles. I have generated two profile strings, one for whether the balance of an account has gone up or down and one for the size of the balance in relation to the normal invoice amount for the customer. So (for example) the balance movement string will look like this:
UUUDUUUDUUUD-D00 Where U = Up, D = Down, - = no change and 0 = no change and no balance
I want to analyse these strings in two ways. The first is that I want to find customers with a similar pattern: in the example below the first and last patterns are the same, just one out of sync but should be considered the same
Movement Multiple CountRecords
UUUDUUUDUUUD1230123012301175
------------0000000000001163
UDUUUDUUUDUU3012301230121082
The second type of analysis is to find customers whose pattern has changed: in the examples above the patterns are repeated and therefore 'normal' in the records below the patterns have changed in that the first part does not match the second part.
Movement Multiple CountRecords
UUDUUUDUUUUU-----------07
UDUUUDUUUUUU------------7
good way to approach this without either a cursor or a hidden REBAR. The challenge as I see it is that I have to interrogate every string to find out if there is a repeating pattern and if so where it starts and how long it is (heuristic because some strings will start with a repeating pattern and then the pattern may change or deteriorate) and then compare the string for N groups of repeating characters to see if and when it changes and I can't think of an efficient method to do this in SQL because it is not a set based operation.
Reporting Services :: Exporting SSRS Reports To PDF With Background Pattern - Pattern Not Visible?
May 8, 2015I tried creating one simple bar chart report in SSRS, with background fill with pattern "UpwardDiagonal", the stripes on the column when viewed insider report viewer control is quite prominently visible, whereas when exporting the same report to PDF the lines are very thin and dense and hence makes it very difficult to differentiate between one column with pattern inside and one without. I have even tried various other pattern like "LightUpwardDiagonal" and "WideUpwardDiagonal" but all have same result when exported to PDF.why?
View 2 Replies View RelatedPattern Matching - Searching For Numeric Or Alpha Or Alpha-Numeric Characters In A String
Aug 18, 2006Hi,
I was trying to find numeric characters in a field of nvarchar. I looked this up in HELP.
Wildcard
Meaning
%
Any string of zero or more characters.
_
Any single character.
[ ]
Any single character within the specified range (for example, [a-f]) or set (for example, [abcdef]).
Any single character not within the specified range (for example, [^a - f]) or set (for example, [^abcdef]).
Nowhere in the examples below it in Help was it explicitly detailed that a user could do this.
In MS Access the # can be substituted for any numeric character such that I could do a WHERE clause:
WHERE
Gift_Date NOT LIKE "####*"
After looking at the above for the [ ] wildcard, it became clear that I could subsitute [0-9] for #:
WHERE
Gift_Date NOT LIKE '[0-9][0-9][0-9][0-9]%'
using single quotes and the % wildcard instead of Access' double quotes and * wildcard.
Just putting this out there for anybody else that is new to SQL, like me.

Returning Matching/Non Matching Records
Feb 4, 2007Hi All
I have a strange request that might not be possible based on the laws of relational databases but I thought I'd give it a try.
I have three tables which for simplicity I will call A, B and C. Table A contains my master records, Table B contains user details and the final table contains some extra data
In my initial search when joining A and B, I return 100 records. I then need to search in table C for these 100 records based on a criteria. the expected result should return all 100 rows for the ones that match and also the ones that do not match. The problem is that in Table C, not all the 100 IDs exist, so there will not be a corresponding record. Unfortunately, our users still want to see all 100 records in the output. Is this possible
As always any help or direction would be appreciated.

Reverse Engineering SPs
Mar 8, 1999Does anyone know of a way to determine the code of a stored procedure that was built with encryption? I inherited a db with many of these and we are not sure which version of the source code exists on the server. Alternatively, can I compile a new SP and compare it to the old one in any way other than testing lots of data?

Reverse Cross Tab
Feb 19, 2002Is is possible to write a query that does the reverse of a cross tab query, I have a table that is mirrored for our Main frame, the table contains a item number a warehouse number and a date field and then 43 fields like field01 thru field43 which store quantities, each field out from 01 is another date our from the date field and I need to look for the item, warehouse and return a date where one of the many field is greater than or equal to the quantity I am looking for, I obviously will have to calculate the date field but thought If I could do the reverse of a cross tab giving a resuld set of 43 records for everyone in the first file I could do a quick update for item number, warehouse match and quantity field greater than what i need returning the date
blah blah blah , sorry I made it sound so confusing
THANKS IN ADVANCE
Reverse Formula
Feb 12, 2008
Hi . My database seems to be somehow encrypted by the software I used. When I try to export my data some fields are encrypted like this:
1 => 31911
2 => 63758
3 => 95540
4 => 127258
5 => 158912
6 => 190504
7 => 222032
8 => 253498
I'm really sure it's not some complicated formula (because I managed to recover other fields) . I just want to reverse the formula used to "encrypt" this data.
Thank you. Excuse my english.
Master - Details In Reverse
Mar 20, 2006HI, I'm using Visual Web Developer and SQL Server 2005 Express Editions. I have a database with two tables, say AccountsTable and PersonsTable, with a one to many relationship respectively.
Given a particular selected record in PersonsTable, I need to look up the corresponding master record in AccountsTable. Here's what I've done:
SqlDataSource1 has a "SELECT * FROM PersonsTable" and a GridView1 which uses this as its datasource and the 'enable Selection' checkbox is On. This works fine.
Then, I create a second SqlDataSource2. When I click on the WHERE button in the Configure Data Source page, I have chosen the following parameters:
Column:PrimaryKeyField; Operator:=; Source=Control; ControlID=GridView1; Default Value='I left this blank' but the Value field shows GridView1.SelectedValue when I click the ADD button.
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:bizConnectionString %>"
SelectCommand="SELECT * FROM [AccountsTable] WHERE ([AccountNumber] = @AccountNumber)">
<SelectParameters>
<asp:ControlParameter ControlID="GridView1" Name="AccountNumber" PropertyName="SelectedValue"
Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
I have bound DetailsView1 to SqlDataSource2. When I run the page, the GridView1 is shown with Persons records OK. Then I click the 'Select' next to a record in the Gridview expecting the corresponding lookup to the master record (Account) to be shown in the DetailsView, but it does not show anything.
What am I doing wrong? Is there a better way of doing this?
Your help is much appreciated. Thank you.
PS. I could find Tutorials showing Master/Details retrieving records in a top down fashion (1:n), but I could not find the reverse (n:1)

DDL Cube Reverse Generate
Aug 9, 2005Hi guys
I have built several cubes. However I would need to create local cubes from the built cubes in Analysis Services. As a result I need to work out the DDL for my existing cubes. However the cube contains many mdx calculated members. I was wondering if it would be easier to simply generate the DDL from my existing cube in Analysis Services.
Does anyone know any third party tools that I can use to reverse engineer the DDL from the built cubes in Analysis Services ?

Reverse-engineer Database
Aug 31, 1998I`d like to find a script that will create a "create" script for an entire database. It would write a create-table script for every table in the database, complete with all the PKs and FKs too.
Since I`m asking for the world (or at least the world`s creation script), then I`d also like the script to (optionally) write insert statements for all the rows currently residing in all the tables.
Do you have such a script? If not, can you give me a couple of pointers to assist me in writing my own?

INDEX Possible For Reverse Wildcards?
Jul 20, 2005If I use _reverse_ wildcard search will it always result in a tablescan? Is it possible to get the DB (Oracle or SQL server) to useindexes when doing reverse wildcard match?let's say I have:table email_address (id int, email varchar)with the following entries2, www.%shoes.%3, w%.super%shoes.%4, %webbox.somecopany.comselect id from email_address where 'www.superdupershoes.com' likeemail;this returns 2,3But the query always results in a table scan even if I add an index toemail. What kind of index can I employ in this situation?Please note that this is a _reverse_ search, the opposite of what'snormally done, i.e. select from email_address where email like'www.%shoes.com'.Thanks!- Robert

Reverse Sign For Display
Aug 13, 2007In Crystal Reports, there was a "reverse sign for display" property that could be checked for a number box. This was used for debits and credits (and such) so a negative number would be displayed as a positive and a positive displayed as a negative.
