I have a task (Derived Column Task) and I want to write something like this :
IsNumeric(aColumnOfString) == true ? "All numbers" : "there are some characters"
Here aColumnOfString can be something like "123a5" or 12345". I do not want to simply check if the left-most character is a number or not. I want to check the entire expression and return me a TRUE or false.
A TRUE is returned if the entire expression contains ONLY numbers, and FALSE otherwise.
I read some posting using regular expression. But that is not a solution for this situation.
CREATE FUNCTION [dbo].[ToTime] ( @intHora int, --A valid hour @intMin int -- A valid minute ) RETURNS smalldatetime AS BEGIN declare @strTime smalldatetime declare @errorvar int
select @strTime=cast(convert(varchar,cast((cast(@intHora as varchar) +':'+ cast(@intMin as varchar)) as smalldatetime),108) as varchar) return @strTime; END
the function works perfect but when the parameter for the hour is a negative number (for example -1), or a number > 23 and the parameter for the minute is an negative number (-1) or a number > 59, the function produce an error. I need handle this error converting the wrong value in 0, but i don't want to do this using "if statement". for example
if @intHora < 0 or @intHora >23 begin set @intHora = 0 end if @intMin <0 or @intMin>59 begin set @intMin = 0 end
please, If someone know some sql function (try - catch doesn't work) to handle this kind of error or some good way to do it, please help me.
I have a holding tree with more than 200 companies, and several layers. Each company is defined by:
- a unique ID - a direct parent ID --> the company immediately above in the tree - an ultimate parent ID --> the company that owns the entire tree, it is the same for all
Now I am looking for a function that returns the list of all companies below a given one in the tree, and there could be several layers underneath. Doing that for the ultimate parent is easy because all companies now who their ultimate parent is, but I am struggling to build a function that works for an intermediary parent in a dynamic way.
i am migrating data from a legacy system with a not nice front-end. as a result, i have all sorts of garbage stored on the tables.
i am trying to convert values from varchar(12) to float, but i have an error during selecting data that says that data can not be converted eventhough i am using the ISNUMERIC() function to check.
case when isNumeric( myCol01 ) = 0 then null else convert( float , myCol01 ) end
but my error occours when ISNUMERIC() encounters the value '. ' ; that is a dot with spaces after it.
2/1/2008 1 2/1/2008 1 2/1/2008 0 2/1/2008 x 2/1/2008 0
The grpMiscError can contain 0, 1 or x only. I need to sum up this column for all the zeros by a particular date. I have the following but doesn't work: SELECT SUM(CASE ISNUMERIC(grpMiscError) WHEN 0 THEN 1 ELSE 0 END)AS MiscError FROM TableA WHERE GrpDate = '2/1/2008'
I get back an answer of 1 MiscError instead of 2 What am I doing wrong here?
HiHere's the problem:I need to search a postcode database by the first one or two letters.Problems occur for example when i want to search north London postcodes (N) when using:postcode LIKE @postcode + '%' As this picks up everything beginning with N, eg, NG for Nottingham, or NE for Newcastle. So i need a like statement which searches for the first one or two digits followed by a number!I've found the ISNUMERIC() function but not sure what the best way to use it with the like statement - or even if there is a better way altogether - can you use regular expressions in MSSQL?thanks
sneaky, sneaky, sneaky ISNUMERIC returns 1 when the input expression evaluates to a valid integer, floating point number, money or decimal type; otherwise it returns 0. A return value of 1 guarantees that expression can be converted to one of these numeric types.
thanks, but which one??
numeric as far as float is concerned, is not the same thing as numeric as far as money is concerned

I'm casting a varchar field to a decimal field using the format
CASE ISNUMERIC(GrossMktCapGbp) WHEN 1 THEN CONVERT(DECIMAL(18,6),GrossMktCapGbp) ELSE NULL end
Thinking this would ensure that any spurious rows got set to null.
However I had a problem with some values that were set to '.', it seems that isnumeric thinks these are numbers but casting them to decimal produces an error.
SELECT ISNUMERIC('.') SELECT CAST('.' AS DECIMAL(18,6))
Should I have been doing something different in my check possibly.
The above expression seems to work fine if Fields!Accreditation.Value is a number. However, if Fields!Accreditation.Value is not a number, it gives an #Error. Why is the true part evaluated when the expression is false?
Been meaning to post this for a while. It does a very limited job of only allowing [0-9], but could be extended to allow negative numbers, or numeric values that are suitable for numeric types other than INT, but avoiding the pitfalls of IsNumeric() which might allow through data not suitable for some of the numeric datatypes

I would like to validate datatype using Derived Column.My data type are such as numeric(X,X),datetime,int, and varchar.How do I do this using Derived Column.Example if row does not qualify as ISNUMERIC()...throw it in ERROR table else send it to SUCCESS table.Any Idea ?
Hello, I have searched the forum, and have discovered that the DTS method using IsNumeric to check for numierc values (ActiveX) is not valid in SSIS. Most of what I have seen prescribes using the script component to handle this.
So formerly, I checked to see if a column was numeric. If it was, then I needed to use the numeric value as is, or in some cases, I needed to perform a calculation on the value and use the result. If the value was not numeric, then whatever the value was needed to be changed to zero.
Here is an example of how I would use the current value, or set the value to zero:
If IsNumeric(DTSSource("Col003")) Then DTSDestination("ADepTrnx") = CLng(DTSSource("Col003")) Else DTSDestination("ADepTrnx") = 0 End If
This is an example of how I would use the current value in a calculation, or set the value to zero:
If IsNumeric(DTSSource("Col012")) Then DTSDestination("AlliStdFee") = CLng(DTSSource("Col012"))/100 Else DTSDestination("AlliStdFee") = 0 End If
Does anyone have an example of how I would handle both situations in a script component?
I've wrote a small query for SQL 2005 and it's doesn't seem to work.
I have a table that contains two columns (X and Y), X is an int and Y is an nvarchar(50). I've populated this table with some data where Y contains numbers and some strings (e.g. "1", "2", "foo", etc). I've then got a view which only returns the rows where Y is numeric - now, I then query this table stating I only want numbers greater than 0 (i've casted the column) but this throws an error stating "foo" can't be casted. This is strange because the view doesn't return that.
What's going on? All of this works fine in SQL 2000 but not in SQL 2005 - looks like it's looking at the underlying table rather than the view. Sample code below to help you all out: -
Create Table ============ CREATE TABLE [dbo].[tblTest]( [X] [int] NOT NULL, [nvarchar](50) NOT NULL ) ON [PRIMARY]
Insert Data =========== INSERT INTO tblTest(X, Y) VALUES(1, '1') INSERT INTO tblTest(X, Y) VALUES(1, '2') INSERT INTO tblTest(X, Y) VALUES(2, 'foo') INSERT INTO tblTest(X, Y) VALUES(2, 'bar')
Create View =========== CREATE VIEW [dbo].[vwTest] AS SELECT X, Y FROM dbo.tblTest WHERE (ISNUMERIC(Y) = 1)
Finally ======= SELECT X, Y FROM dbo.vwTest WHERE (CONVERT(int, Y) >= 0)
Msg 245, Level 16, State 1, Line 1 Conversion failed when converting the nvarchar value 'foo' to data type int.
I'm using service broker and keep getting errors in the log even though everythig is working as expected
SQL Server 2005 Two databases Two end points - 1 in each database Two stored procedures: SP1 is activated when a message enters the sending queue. it insert a new row in a table SP2 is activated when a response is sent from the receiving queue. it cleans up the sending queue.
I have a table with an update trigger In that trigger, if the updted row meets a certain condition a dialogue is created and a message is sent to the sending queue. I know that SP1 and SP2 are behaving properly because i get the expected result. Sp1 is inserteding the expected data in the table SP2 is cleaning up the sending queue.
In the Sql Server log however i'm getting errors on both of the stored procs. error #1 The activated proc <SP 1 Name> running on queue Applications.dbo.ffreceiverQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
error #2 The activated proc <SP 2 Name> running on queue ADAPT_APP.dbo.ffsenderQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
I would appreceiate anybody's help into why i'm getting this. have i set up the stored procs in correctly?
i can provide code of the stored procs if that helps.
Hi - Please excuse me if this is really simple, but I'm fairly new to this lark.
My (made up) code is below... I'd be grateful for any pointers.
insert into [tblInvoices] (full_period, supplier_no, account_code, tran_amount, function) select full_period, supplier_no, account_code, tran_amount case when substring(account_code,1,2) = 'FY' then '-' when isNumeric(account_code) then left(account_code, 2) when not isNumeric(substring(account_code,1,2)) then left(account_code, 1) else 'oops' end as function, from tblLoadMSV900_i end
Is this even close?
I'm using a stored proc to insert the data from tblLoadMSV900_i into tblInvoices and at the same time insert some data into the function field.
In plain english I want make sure that: If the first 2 chars of account_code are 'FY' then function='-', If the first char of account_code is numeric then function=left(account_code, 2), If the the first char is not numeric (and if first two chars are not 'FY' i.e. first char could be 'F') then function=left(account_code, 1)
And there's plenty more where this came from! But if I can crack this with your help then I should have a better idea about the rest of the proc.
There is a MSSQL function that check the value. Like ISNULL(), ISDATE() and ISNUMERIC(). I don't see a function that check for decimal. If there isn't any then is there an user-defined function for it? I need to be able to validate the string value for decimal before it get assigned to a decimal datatype or T-SQL will run into an error.
SELECT uri, evFieldUri, evFieldVal , CAST(evFieldVal AS BIGINT) FROM TSEXFIELDV
[Code] ....
And it returns this error:
Msg 8114, Level 16, State 5, Line 1 Error converting data type varchar to bigint.
So, I tried again, and this worked…
SELECT uri, evFieldUri, evFieldVal,CAST(evFieldVal AS BIGINT), ISNUMERIC(evFieldVal) FROM TSEXFIELDV WHERE URI > 0 AND evFieldUri IN ( SELECT URI FROM TSEXFIELD WHERE exFieldFormat IN (1,11))
I logged out and came back and tried again, and it still worked. So then I tried…
SELECT uri, evFieldUri, evFieldVal,CAST(evFieldVal AS BIGINT) FROM TSEXFIELDV WHERE URI > 0
We have implemented our service broker architecture using conversation handle reuse per MS/Remus's recommendations. We have all of the sudden started receiving the conversation handle not found errors in the sql log every hour or so (which makes perfect sense considering the dialog timer is set for 1 hour). My question is...is this expected behavior when you have employed conversation recycling? Should you expect to see these messages pop up every hour, but the logic in the queuing proc says to retry after deleting from your conversation handle table so the messages is enqueued as expected?
Second question...i think i know why we were not receiving these errors before and wanted to confirm this theory as well. In the queuing proc I was not initializing the variable @Counter to 0 so when it came down to the retry logic it could not add 1 to null so was never entering that part of the code...I am guessing with this set up it would actually output the error to the application calling the queueing proc and NOT into the SQL error logs...is this a correct assumption?
I have attached an example of one of the queuing procs below:
Code Block DECLARE @conversationHandle UNIQUEIDENTIFIER, @err int, @counter int, @DialogTimeOut int, @Message nvarchar(max), @SendType int, @ConversationID uniqueidentifier select @Counter = 0 -- THIS PART VERY IMPORTANT LOL :) select @DialogTimeOut = Value from dbo.tConfiguration with (nolock) where keyvalue = 'ConversationEndpoints' and subvalue = 'DeleteAfterSec' WHILE (1=1) BEGIN -- Lookup the current SPIDs handle SELECT @conversationHandle = [handle] FROM tConversationSPID with (nolock) WHERE spid = @@SPID and messagetype = 'TestQueueMsg'; IF @conversationHandle IS NULL BEGIN BEGIN DIALOG CONVERSATION @conversationHandle FROM SERVICE [InitiatorQueue_SER] TO SERVICE 'ReceiveTestQueue_SER' ON CONTRACT [TestQueueMsg_CON] WITH ENCRYPTION = OFF; BEGIN CONVERSATION TIMER ( @conversationHandle ) TIMEOUT = @DialogTimeOut -- insert the conversation in the association table INSERT INTO tConversationSPID ([spid], MessageType,[handle]) VALUES (@@SPID, 'TestQueueMsg', @conversationHandle);
SEND ON CONVERSATION @conversationHandle MESSAGE TYPE [TestQueueMsg] (@Message)
END ELSE IF @conversationHandle IS NOT NULL BEGIN SEND ON CONVERSATION @conversationHandle MESSAGE TYPE [TestQueueMsg] (@Message) END SELECT @err = @@ERROR; -- if succeeded, exit the loop now IF (@err = 0) BREAK; SELECT @counter = @counter + 1; IF @counter > 10 BEGIN -- Refer to http://msdn2.microsoft.com/en-us/library/ms164086.aspx for severity levels EXEC spLogMessageQueue 20002, 8, 'Failed to SEND on a conversation for more than 10 times. Error %i.' BREAK; END -- We tried on the said conversation, but failed -- remove the record from the association table, then -- let the loop try again DELETE FROM tConversationSPID WHERE [spid] = @@SPID; SELECT @conversationHandle = NULL; END;
I have another issue. I have an excel file that I pipe through a "data conversion" task. I have set all the column data types to strings, because there's no way to know beforehand if a particular column will be number or text because the file is very non-standard (it looks more like a formatted report).
After the data conversion, I send all the rows to a script task. In the script task, I do a check on the numeric fields.
for example:
If Not IsNumeric(Row.Price) Then
Row.Price_IsNull = True
End If
However, this check fails each and every time, even if the field contains a number! I don't have this problem when using flat file sources.
So, none of my numeric fields are getting loaded to my ole db destination.
Help, is there a way around this? Or am I forced to just skip this number check altogether? I'd prefer not to.
SET @VRUSERVICEMIN = 46 SET @BILLEDFLAT = 0 -- PROCESS ONLY RECORDS WHERE THERE IS NO FLAT FEE IF @BILLEDFLAT = 0 BEGIN IF @VRUSERVICEMIN BETWEEN 0 AND 15 BEGIN SET @VRUSERVICEMIN = .25 END ELSE IF @VRUSERVICEMIN = 15 BEGIN SET @VRUSERVICEMIN = .25 END ELSE IF @VRUSERVICEMIN BETWEEN 15 AND 30 BEGIN SET @VRUSERVICEMIN = .5 END ELSE IF @VRUSERVICEMIN = 30 BEGIN SET @VRUSERVICEMIN = .5 END ELSE IF @VRUSERVICEMIN BETWEEN 30 AND 45 BEGIN SET @VRUSERVICEMIN = .75 END ELSE IF @VRUSERVICEMIN = 45 BEGIN SET @VRUSERVICEMIN = .75 END ELSE IF @VRUSERVICEMIN > 45 BEGIN SET @VRUSERVICEMIN = 1 END END
Is it possible to catch and error and then keep the process going in a stored procedure? So if an update encounters a primary key violation on a row, is it possible to skip that row and keep the process going?
Hi! I have some try .. catch block trying to insert some data into database. During its action duplicate key row insert error could raise, for example. The question is how could I know distinguish it from other sql errors? Object ex (Catch ex As Exception) has only message property '{"Cannot insert duplicate key row in object 'dbo.Group_Courses' with unique index 'IX_Group_Courses'.The statement has been terminated."}' and type System.Data.SqlClient.SqlException. Knowing the type of error is not enough, because there are different SqlExceptions. Even the message is not unique for this error, because now i deal with 'dbo.Group_Courses' and then it could be other table. Is there something that unique identifies each error? For example error code. If it exists, where could I get it? Thanks in advance!
I test my the now function and it is getting the right date. When I try to send that to the sql database I have it turns it into 1/1/1900. Does anyone know why this is happening, I have tried everything Here is my code:
Hi, I would like to handle a sql error in t-sql and return a certain value in case error occurs. For example if I would like to add a record I want to return a certain identity value or maybe a status of transaction (0 for incomplete, 1 for succesfull trans). If error occurs in sql I cannot return any values back to asp.net because of What I am doing at the moment is catching an error in asp.net and then displaying an error message. Is there a way to return only a return value to asp.net and somehow handle the error in t-sql? Thanks
I don't know what's wrong with SQL2000 setup, the problem is: whenever I execute a query with a date/time such as 02/02/200, SQL give me an error message saying that the date is "Out of Range".
I'm having trouble with something and I was hoping that you could point me in the right direction.
Here's the scenario: I have a VB application that clients use to add records to a SQK 2K DB. The info they have added that day is shown in a grid. They have the ability to edit items in the grid, and then update those changes to the database. The problem is that sometimes they change the values to something they shouldn't. To combat this I've started experimenting with check constraints. In query analyzer I test the constraint by trying to update an entry to an 'illegal' value. When I do this, I get an error saying: "Server: Msg 547, Level 16, State 1, Line 1" and the change is not made. What I'd like to do is to give the user a dialog box notifying him of the error. Is there a way to have a sub-routine or stored procedure be triggered when a message of this type is generated?
My specs are: W2K pro clients, SQL2K on an NT4 sp6a server. Application is written in VB6.
I have a select statement that works, but I know there has to be a better way( I apologize for being TSQL brain dead today). Here is the statement
SELECT PATIENT_ACPT_STATUS, DISP_NOTES, RECORD_ID, modified_by, last_name, ddate FROM PATIENT_MEDICATION_DISPERSAL_ Where (ddate = convert(char(10),getdate(),101) and (MODIFIED_BY = CURRENT_USER) and rec_status = 1) or (ddate = convert(char(10),getdate(),101) and (PATIENT_ACPT_STATUS = 1)) OR (ddate = convert(char(10),getdate(),101) and (MODIFIED_BY = 'open'))
