String Function - InStr
Dec 11, 2002
In VB there is InStr, in Excel you have SEARCH. what function can i use to search a string for a specific string. ie: how can i find where a space is in someones name?
our database has a table that is used for security. it contains a user code, user name and passcode. i need to split the username (currently forename and surname in same field) into two, around the space.
in VB i would write something like
strFName = left(<usernamefield>,InStr(1,<usernamefield>," ")-1)
to get the forename and similar to get the surname. how can i do this in SQL so that a view will supply the data apprpriately?
one of the reasons i want to do this is so that i can sort the users by surname! another is so that i can give options on their usercode - a combination of forename initial and 2 characters from surname.
any help welcomed.

Hello there...
I am looking for the function that is the same as InStr in Access for SQL server. I have a column that has format like this.. Lastname,Firstname Middlename...
This column doesn't separate each one of them. However I need to separate Lastname and Firstname and Middlename.. I was told that in Access there is function(InStr) that can find a position of comma and separate it as Lastname like that....
I was searching BOL but I couldn't find like this function in SQL Server..
So I need help:-))))
Because everybody has a different length of the lastname, I have a problem.
I can not use SUBSTRING or LEFT or RIGHT because of the varying position of comma ...
Thanks in advance

I went to Microsoft to find some info about the function Instr. I need to
perform a search with a string similar to their example I found below. Can
anyone explain to me Microsoft's example?? I am little confused by the
parameters used and the explanation it gives back to me??
Dim SearchString, SearchChar, MyPos
SearchString ="XXpXXpXXPXXP" ' String to search in.
SearchChar = "P" ' Search for "P".
MyPos = Instr(4, SearchString, SearchChar, 1) ' A textual comparison
starting at position 4. Returns 6.
MyPos = Instr(1, SearchString, SearchChar, 0) ' A binary comparison
starting at position 1. Returns 9.
MyPos = Instr(SearchString, SearchChar) ' Comparison is binary by default
(last argument is omitted). Returns 9.
MyPos = Instr(1, SearchString, "W") ' A binary comparison starting at
position 1. Returns 0 ("W" is not found).
My problem is this:
I need to scan within SearchString for blanks/spaces characters. When I
find one, then place the values to the left and right of it in seperate
columns. For example, I would need to scan 'John Smith A' and then place
'John' in FirstName column, 'Smith' in LastName column, and 'A' in MidName
column.
I think this is how my code would read, but I am confused on how to place
the results into my table to the correct columns?
my search string would be SearchString = 'John Smith A'
my SearchChar would be SearchChar = ' ' (note I am searching for a
space/blank character)
So would then my code be like:
Dim SearchString, SearchChar, MyPos
SearchString = 'John Smith A'
SearchChar = ' '
MyPos = Instr(1, SearchString, SearchChar, 0)
How do I get whatever is returned from the Instr function to a column in a
table??
Any help would be great.

Hi All
My SQL is extremly rusted so I need some help with a very basic function. I have a character field which is built up using a category code + '-' + number. The problem I have is that the category codes are all different lengths and the items were added using 9 instead of 09. I'm trying to clean up the data so that the same item with e.g. category code DZ20 cannot be added as DZ20-1 and DZ20-01. How do I find the position of the '-' in the Query Analyser for MSSQL 2000?

TASK: At my work we want to categorize and summarize all our IIS web logs and make statistics from it and such. What I need to do is take the browser type from a certain column in the table. All the information is stored in 1 column, and I figure an instr function would be best to do this. I am new to SQL, so I was told to look up the cursor function. In summary, I want to take all the IIS data and match it up against a defined table and then have a sum function for each browser.
Here are some examples of what the column data looks like: (found in the [csMethod] column
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+2.0.50727)
Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.04506.30;+InfoPath.2;+.NET+CLR+1.1.4322)
Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US;+rv:1.8.0.8)+Gecko/20061025+Firefox/1.5.0.8
I made a define table which lists an ID (primary key) and instr to search for as well as the full browser name. (define.browser)
DEFINE.BROWSER
ID# INSTR# BROWSER NAME
###############################
1___Opera+7_______Opera 7
2___Opera/9_______Opera 9
3___Safari/_______Safari
4___Firefox/1.0___Mozilla Firefox 1.0

8___MSIE+5________Microsoft Internet Explorer 5

I am having problems getting a cursor to work. Are there any good tutorials out there, or can anyone be of assistance. Thank you in advance.

I am trying to convert a complex function from Oracle to SQL Serverand have come across Oracle's Instr() function. I see SQL Server hasCHARINDEX() which is similar, however it does not provide some keyfunctionality I need. Here is an example of the Oracle code:if Instr( sTg , cDelim, 1, 3 ) > 0 thensd := SubStr( sTg, Instr( sTg , cDelim, 1, 1 ) + 1, Instr( sTg,cDelim, 1, 2 ) - Instr( sTg , cDelim, 1, 1 ) - 1)end if;Has anybody converted anything similar to this within SQL Server? Anyhelp is GREATLY appreciated!Thanks.

The syntax for Oracle's INSTR function is
instr (string1, string2, [start_position], [nth_appearance])
string1 is the string to search.
string2 is the substring to search for in string1.
start_position is the position in string1 where the search will start. This argument is optional. If omitted, it defaults to 1. The first position in the string is 1. If the start_position is negative, the function counts back start_position number of characters from the end of string1 and then searches towards the beginning of string1.
nth_appearance is the nth appearance of string2. This is optional. If omiited, it defaults to 1.
In SQL Server, we are having CHARINDEX and PATINDEX functions. But they will not accept the fourth paremeter (nth_appearance)
Do anybody know the solution for this ????

I have a field that contains a town  ex : New York. Sometimes, the field will have brackets to be more specific ex: New York (Brooklyn). What I need is a formula that will return only "Brooklyn" if there are brackets or  the whole field if there are no brackets.Here's what I thought would do the trick :
=Iif(InStr(First(Fields!Ville.Value, "MW1R017A_IdentificationTravailleur_AdresseTravailleur"), "(") > 0,
Left(Split(First(Fields!Ville.Value, "MW1R017A_IdentificationTravailleur_AdresseTravailleur"), "(")(1), len(Split(First(Fields!Ville.Value, "MW1R017A_IdentificationTravailleur_AdresseTravailleur"), "(")(1)) - 1)
, First(Fields!Ville.Value, "MW1R017A_IdentificationTravailleur_AdresseTravailleur"))
So if InStr returns more than 0, meaning that I have brackets, I'll split at the "(", get the second part and remove the last character which is the closing bracket I don't want. If there is no bracket, I'll return the whole field.Somehow, when there is no bracket, my report overview shows me "#Error" as if the first Iif was true and what's in the true part is not actually possible, because it's trying to take the second part of a split that couldn't split because there is no bracket to split.

I need to take the character from a text field. I need the character which
is the second one from the end(right). Like out of '12345' or '99821'
I would need the 4 from the first and the 2 from the second. Can I combine
a string and a right statement to do this?
Thanks

Here is the scenario.
I have a 10 position varchar field that holds a project number. The project number is in the form yy-nnn... where yy is the current year (06) and nnn is a sequential number. The project number is displayed on a data entry form so that the next record has the next sequential number.
So when the data entry form first opens the project number field has 06-1 after that record is entered the form is cleared and reinitialized and the project number now shows 06-2. If the form is closed and then reopened the project number would still show 06-2 if that previous record was not entered and 06-3 if it was.
The way I am going about getting the next sequential number is the following:
SELECT MAX(RIGHT(ERFNumber, LEN(ERFNumber)-3)) AS MaxERFNumber From Table1
This approach is working fantastic until record 06-9 is entered. The above line does determine that 06-9 is the MAX record and then creates a record 06-10 but every subsequent time a record is attempted it still thinks 06-9 is the MAX value of the above statement.
I am assuming that since the field is defined as a varchar the MAX function is applying character logic versus numeric logic thus the 9 being treated as the MAX value.
Is there an SQL function that can change the result of RIGHT(ERFNumber, LEN(ERFNumber)-3) to a numeric value so that the MAX function will work correctly.
I know there are many other ways to do this but in the interest of time because the application is almost finished, changing this now is going to be a major undertaking.
Any help or guidence would be greatly appreciated.

This function is useful for fixed width output. E.g.
String(expr,10-len(expr),'0') will give you a number with leading zeros so it is always 10 characters long.

The 'LIKE' function looks for words that start with whatever is in the like condition. Is there an sql function similar but will look and compare at any part of the search string.
For example I am using a webservice in dot net to populate a dropdown list using this sql
SELECT compound_name FROM dbo.compound_name WHERE compound_name like @prefixText
In this table there is a compound called SILCAP310 and I would like the search function to pick up 310 if I put this into the @prefix parameter. (but I would still like the search to perform like the 'LIKE' does also.
SELECT compound_name FROM dbo.compound_name WHERE compound_name like @prefixText or compound_name SearchPartString @prefixText
Thanks in advance

select left('Hello World /Ok',charindex('/','Hello World /Ok')-1)Hello WorldThat works fine.However I got an error message:select left('Hello World Ok',charindex('/','Hello World Ok')-1)Instead of:'Hello World Ok'I get:Server: Msg 536, Level 16, State 3, Line 1Invalid length parameter passed to the substring function.Microsoft Doc incorrectly says:"LEFT ( character_expression , integer_expression )integer_expressionIs a positive whole number. If integer_expression is negative, a nullstring is returned."Is there an easier solutoin using left or any other string functioninstead of using a case statement?Also, charindex('/','Hello World Ok') should return NULL instead 0 sothat we can use isnull function.Thanks.
