select left('Hello World /Ok',charindex('/','Hello World /Ok')-1)
Hello World
That 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 1
Invalid length parameter passed to the substring function.
Microsoft Doc incorrectly says:
"LEFT ( character_expression , integer_expression )
integer_expression
Is a positive whole number. If integer_expression is negative, a null
string is returned."
Is there an easier solutoin using left or any other string function
instead of using a case statement?
Also, charindex('/','Hello World Ok') should return NULL instead 0 so
that we can use isnull function.
Thanks.
I normally use MS ACCESS vs MS SQL,, which has a left() and right()function. I need to use MS SQL for this project but I am not familiarwith it. I have read a few books, but can not figure out how to dothis. Please help.If I need to compare the first 4 letters of a field, with the firstfour letters of another field, how can I do this?Select field1, field2 FROM table1 Where left(field1,4)=left(field2,4)(MS SQL does not have left() and right() functions)Please help.In addition, I have a CSV file with data like 10.20, which I importinrto a numberic field. Unforunately the value gets changed to 10.It's seems to get rounded. How can I fix this.The import SQL I use is....BULK INSERT dbo.tableFROM 'c:MYDATA.CSVWITH(FIRSTROW = 1,FIELDTERMINATOR = ',',ROWTERMINATOR = '')Thank you in advance!!!
How do you combine a left and a right function. I have tried different variation and none seemed to work. What I want to accomplish is 6 spaces to the right and 2 spaces to the left.
I have not been able to find the answer as to why the LEFT() function doesn't see the variable as being a variable. I originally thought it did not accept a variable as the first parameter, however the definition says it can be a variable. Anyone knows why this isn't working? This is how I have the code:
SELECT LEFT(@tpatdata, CHARINDEX('^', Alert1) -1)
the variable @tpatdata is the column name (tablename.Alert1), iif I rewrite it like this:
SELECT LEFT(tablename.Alert1, CHARINDEX('^', Alert1) -1) it works.
I've tried the following query in SQL SERVER 2005, SQL Express and MACCESS.
select * from Table1 where drid in (SELECT DrID FROM Table2 WHERE (substring(PostalCode,1,3) IN ('B0E','B1P','B2H','B2Y','B3A','B3M','B4A','B4H','E1A','E1C','E1N','G0A', …)) and (substring(Telephone,1,3) IN ('204','250','306','403','416','418','450','506','514','519','604','613','705','780','807','819','902','905')))
The query is using two table. The first one Table1 is a table with user info. The second table Table2 has the info concerning a survey.
The Table1 containt approx. 6000 row and Table2 containt only 210 rows
The table structure from the different environment(MACCESS, SQL SERVER 2005, Sql Server Express 2005) are the same. The Table1 containt the field "PostalCode" and "Telephone".
When I execute this query on MACCESS and in SQL Server 2005 the result are approximately the same(Less than half second). But there a performance issue in Sql Express 2005. The query take an execution time between 7 and 9 secondes.
When I add a condition using a field from tblResponsePQ2Part1 ex: QA=1 like in the following query : select * from Table1 where drid in (SELECT DrID FROM Table2 WHERE (QA = 1 substring(PostalCode,1,3) IN ('B0E','B1P','B2H','B2Y','B3A','B3M','B4A','B4H','E1A','E1C','E1N','G0A', …)) and (substring(Telephone,1,3) IN ('204','250','306','403','416','418','450','506','514','519','604','613','705','780','807','819','902','905'))) the query take an execution time of ~15 secondes!!!!
This issue only happen in Sql Server Express, on the others cases(mean MSAccess, Sql Server) the execution time is less than half second.
It’s weird because, Sql Express 2005 is supposed to be more performant than MACCESS, and have the same performance than Sql Server Professional Edition. Please Help Me!!!!
i have a column name remarks and i want to retrieve data like by deleting some of the leading charaters and some last characters and show the middle one.
like remarks has CALLTRANSFER_OVER_SIP:XfrTime=86.05599975585938_en and i want to show only "XfrTime=86.05599975585938" this much
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 need to left pad the column with 0 if it is less than 4 characters long and extract the first 2 characters on the left into a new column COUNTY_CODE.
How can I do that in transact SQL?
I tried:
SELECT RIGHT(RTRIM('0000'+ISNULL([Code],'')),4) FROM [Place] WHERE [Place Code]='B' and [Code]='627'
And I got 0627. And how do I extract the first 2 characters?
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
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.
Hi all, iam trying to find a string function which would replace column value where there is a ssn with 1 and anything else(blank,null,...) with 0. i need to count the number of rows with ssn and one without ssn. i checked few string functions but no use
result set should be like this pk_transactionid transactiondate description --> this is concatenated 1 1/1/2007 record1, record4, record6 2 1/2/2007 record2, record5 3 1/3/2007 record 6
select distinct(f.agency+y.year+s.type) as SDNFIn this select clause, I try to use the last 2 digit of year for y.yearvalue. which function should i apply to it?
I have a table with a column called Userdef. I is a user defined field. It looks like this ;;Polk;D-0002;;;;As you can see it is delimited by semicolons. I need to separate the semicolons into separate files like this Field1Field2Field2Field4Field5Field6<null><null>Polk<null>D-0002<null>How do I write this query in SQL Server?
Hello All, I have am importing a file that contains an address field where the city and state are in the same field, IE ['Atlanta, GA']. How do I separate the city and state into separate fields. I can get the state by using the RIGHT function. My problem is getting the city information up to the comma.
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.
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
Hope someone can help... I need a function to parse a string using a beginning character parameter and an ending character parameter and extract what is between them. For example.....
Here is the sample string: MFD-2fdr4.zip
CREATE FUNCTION Parse(String, '-' , '.') ..... .... ..... END
I'm having issues trying to build an expression using the FINDSTRING function. Even when I use an example from BOL, I get an error upon clicking the "evaluate expression" button within expression builder saying "Cannot convert system.int32 to system.string".
Here is my test expression...
Code SnippetFINDSTRING("ABC", "A", 1)
Here is the BOL expression... Code SnippetFINDSTRING("New York, NY, NY", "NY", 1) Both give me the same error message. I even tried casting it to an integer with no luck. Any ideas? Code Snippet(DT_I4) FINDSTRING("ABC" , "A" , 1)
Cannot see where I am going wrong. I always get a value of 0. I know my function works correctly, so it must be the VB.
