I Am Looking For The Function That Is The Same As InStr In Access

Jan 29, 2001

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

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.

Instr (vbscript) Function Explanation ???

Jan 15, 2001

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

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

Any help would be great.

Instr Function For MSQL Query

Jun 4, 2007

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?

Class Method Is Smoking Fast When Executed Outside Of SQLServer, Dog Slow As A CLR Function Is SQLServer - Anyone?

May 10, 2007

We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?

Here is the class:

Code Snippet

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Predict.Services
public static class Foo
public static string GetIntradayQuote(string symbol)
string returnQuote = "";

HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));

request.Timeout = 1000;

HttpWebResponse response = (HttpWebResponse)(request.GetResponse());

StreamReader streamReader = new StreamReader(response.GetResponseStream());

returnQuote = streamReader.ReadToEnd();


return returnQuote;

When I run call it from a console app it is fine.

I compile it into a dll and then create the assembly and function as follows:

Code Snippet

drop function fnTestGetIntradayQuoteXML_SJS


drop assembly TestGetIntradayQuoteXML_SJS


create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS


CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote


declare @testing nvarchar(max)

set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')

print @testing

When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?

Create A TO_DATE Function For Use In SQLServer 2005

Feb 28, 2008

Hi ,

I 'm working with visual studio 2005 and I have created an SQLServer Project.
I'm using the CLR functionality which comes with SQLserver 2005. This means that I can write VB.nEt code and use it inside Sqlserver 2005.So far so good.
I am now inside the .NET
I have created a Function(must remind you that I have created an SQLserver Project) which takes two string arguments. The date value in a string format and the string format.

In Our case the function returns a string.It will return a datetime although.
So we have

Dim Datetime_Val As DateTime = Nothing
Dim Date_Val As Date = Nothing
Dim StrTemp As String = ""
Dim StrDateTemp As String = Nothing
Dim StrTimeTemp As String = Nothing
Dim ls_return As String = Nothing
Dim lindexof As Integer
Dim Counter As Integer = 0

lindexof = 0
Select Case StrFormat
For Counter = 1 To 2
lindexof = StrDate.IndexOf("-", lindexof + 1)
lindexof += 5

StrDateTemp = StrDate.Substring(0, lindexof).Trim
StrTimeTemp = StrDate.Substring(StrDateTemp.Length, StrDate.Length - StrDateTemp.Length).Trim
ls_return = StrDateTemp & " " & StrTimeTemp

End Select

The above is a simple code. As you can see I'm trying to convert the TO_DATE function ,which work with ORACLE, to make it work with SQLServer 2005.
I've been trying unsuccessfully to combine the variables StrDateTemp and StrTimeTemp into a datetime value. I used the following code but nothing

Datetime_Val = CDate(StrDateTemp & " " & StrTimeTemp)
Didn't work

Datetime_Val = Convert.ToDateTime(StrDateTemp & " " & StrTimeTemp)
Didn't work

Datetime_Val = DateTime.Parse(StrDateTemp & " " & StrTimeTemp)
Didn't work

Inside SQlServer I used this SQL statement

Select dbo.TO_DATE('31-12-1990 00:26:46','DD-MM-YYYY HH24:MIS')

But I am receiveing an error. I want to avoid changing all of my applications with a specific format.This sql statement without the dbo prefix I'm using in Oracle. I want to keep the format of the SQL and let VB.NET do the parsing for me. It is easier for me to put in my SQLs the dbo infront rather changing the complete SQL.
I have two questions . How am I going to create a TO_DATE function which Oracle uses and write something similar in SQLserver ?
And If I cannot do that how am I going to get the database 's datetime format and create with VB.NET the Datetime value from the two variables ?

My problem I believe is quite complex. I would be mostly appreciated if you could help me on this.

Thank you

Using CURSOR For INSTR Purposes

Mar 21, 2007

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


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)


1___Opera+7_______Opera 7
2___Opera/9_______Opera 9
4___Firefox/1.0___Mozilla Firefox 1.0
5___Firefox/1.5___Mozilla Firefox 1.5
6___Firefox/2.0___Mozilla Firefox 2.0
7___MSIE+5.5______Microsoft Internet Explorer 5.5
8___MSIE+5________Microsoft Internet Explorer 5
9___MSIE+6________Microsoft Internet Explorer 6
10___MSIE+7________Microsoft Internet Explorer 7
11_________________OTHER BROWSER

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.

Instr() Equivalent In SQL Server

Jul 20, 2005

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.

Equivalent Of Oracle's INSTR( With 4 Parameters) In SQL Server

Feb 2, 2005

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 ????

Reporting Services :: Getting Error Displayed When Using InStr

Nov 18, 2015

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.

Sep 20, 2006

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))

Insert Data
insert into testunicode (Bez)values('')
with 2 Unicode characters
= 0x2300
= 0x2122

When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'')

and select again voila i see
Does anyone have an idea?

Trying To 'load' A Copy Of A SQLServer 2000 Database To SQLServer 2005 Express

Apr 18, 2008

I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.

I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?

The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.

Replacing Sqlserver 2000 With Sqlserver 2005 Express

Jun 14, 2006

I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.

Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.

If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:

server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"

DB name: name of db instance

port: 1433(default)

user and pass.

My attempts so far results in

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."


"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."

SQLSERVER 2005 X64 Linked Server To SQLSERVER 7.0

Jun 20, 2007

Hello people.

I am in the process of planning a server upgrade to sql2005 x64.

I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.

I have the following error when I query the linked servers.
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error".
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.

I am aware of KB 906954.;en-us;906954

I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.

However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.

Can someone help me find a solution to this?
