When I run this code on a column of the type float or real it's ok, but not if the column is decimal, why?
this produces an error:
SELECT IsNull(column1,'') as column1
FROM mytable
---
this code works:
SELECT IsNull(column1,0) as column1
FROM mytable
---
The problem is that this query is used in a C++ environment to build an insert into another table. The query is build together in a CString.
C++ considers a CString to have ended if it encounters a NULL, therefore I need the check on all columns.
The error message I get is:
"Error converting data type varchar to numeric."
Why is it ok to use float or rel, but not decimal??
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.
I have built a DTS package in SQL Server 2000 to Delete all rows from a table and then import from another table. I have scheduled it run twice a day and everytime it runs, it does not delete anything but imports all the records from another table. So when its done, I have twice the number of records in my final table. Then I go back to the server and execute the package manually and it works perfect. It deletes all and then imports new. I have enabled package logging and it shows both the steps executed perfectly (even when it executes on scheduled time). What can be the problem? Thanks, Bullpit
I am so confused. I hope someone can help! I wrote a large stored procedure that is meant to be called from a VB application. The store procedure collects data from several tables and buildsa new table of summary data. It is called with 4 parameters (date ranges and names for the new summary tables to create).
I tested the SP in SQL 7 while developing it, and never had any problems. But when I tried it in 6.5, it complained that I had too many subqueries. So I rewrote the procedure with less nestings, and then when I tried it I didn't get an error but it crashed with a DB Disconnected error.
I rewrote it again and then it finally worked (but only from Enterprise Manager); when I called from a VB application (using ADO), I get an error "protocol error in TDS stream." And looking in the SQL error log I see a whole lot of errors, none of which I understand, but the first mesage is "EXCEPTION_ACCESS_VIOLATION raised, attempting to create symptom dump.
I know that without knowing the contents of the stored procedure, there's no way anybody can tell me exactly what's going wrong, but I'm sure hoping that some people can give me some clues or directions to look. I'm desperate and have been working on this one project for too long already!
MY DATABASE FOR SHOPPING CART IS ACTING STRANGE IT HAS AUTOMATICALLY DESTOYED ALL PRIMARY KEYS. AND HAS CREATED 4 DUPLICATE RECORDS FOR EACH RECORD SO AT THIS STAGE I HAVE AROUNG 15000 RECORDS IN EACH TABLE IT MEANS 15 TIMES 4 60000 RECORDS. CAN ANYONE UPDATEME WHY THIS HAS HAPPENED AND WHAT CAN BE DONE TO DELETE EXISTING DUPLICATES. I NEED FAST REPLY IN THIS MATTER AS THIS IS URGENT. IF POSSIBLE KINDLY WRITE QUERIES TRIGGERS FOR FUTURE PROBLEMS AS WELL AS THESE DAYS I AM SICK SO MY BRAIN AINT WORKING IN THIS MATTER. URGENT URGENT URGENT THANKS ALOT I HAVE PREVIOUSLY POSTED AND HAVE GOT A GOOD RESPONSE. AND HOPE A GOOD ONE AGAIN. ONE MORE THING IS THAT I HAVE A BACKUP HERE AT MY OFFICE SYSTEM IT ALSO HAS DONE THE SAMETHING. I MADE A NEW DATABASE AND TRYED TO IMPORT DATA WITH DISTINCT KEYWORD BUUT IT IS NOT COPYING IT AS WELL. URGENT RESPONSE REQUIRED IF ANYONE CAN DO.

I wonder if anyone can explain what I am doing wrong here:
I need to transport data between several tables using dataflow components. I need to wrap this in transactions to either succeed or fail completly, I do want to use my own BEGIN TRAN and COMMIT TRAN statements, not the transaction support built into SSIS.
As written in several BLOGs, I should set the "RetainConnection" property to "TRUE" to make sure each dataflow runs on the same connection as the BEGIN and COMMIT statements... and that seems to be random.
Sometimes they do run on the same connection, but I also logged (using SQL Profiler) package executions where the BEGIN TRAN was issued to SPID different than the one used in first dataflow, another SPID again for the second dataflow and finally yet another for the COMMIT... in this case COMMIT fails with "needs an open transaction".
One of my table, dbo.Customer, gives me different values of "row count" everytime I check the properties.
The dbo.Customer have around 12 000 rows but when I check the properties (or open the table) the value always differs. The table row count can have any value from ~9000 - 12000.
Its like the table are trying to load all rows but cant.

I am trying to import some data from csv files. When I try it using bulk insert I get a conversion error. When I use the exact same format file and data file with an openrowset it works fine. I would prefer to use the BULK insert as I can make some generic stored procedures to handle all my imports and not have to code the column names in the SQL. Any suggestions?
BULK Insert stuff
From 'c:projects estdatalist.txt'
with
(FORMATFILE='c:projects estdatamyformat.xml')
insert into stuff (ExternalId, Description, ScheduledDate, SentDate, Name)
select *
from OPENROWSET (BULK 'c:projects estdatalist.txt',
FORMATFILE='c:projects estdatamyformat.xml')
as t1
The destination table has more columns than the data file. The Field IDs represent the ordinal position of the columns in the destination table. Column 1 in the destination table is an int identity. The conversion failure is from trying to convert column 5 to int which makes me think bulk insert is ignoring the name attributes in the XML and just trying to insert the columns into the table in order without skipping.
I am having quesion about attributes acting as both inputs and predictive outputs in a mining models, I mean if we are going to predict the outputs, then I cant actually see the effects of themselves acting as inputs as well?
I dont really see through the points of it.
Could please any experts here shed me any light on it.
I am looking forward to hearing from you shortly and thanks a lot in advance.
I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?
Example: AutomobileTypeId (PK, decimal(10,0), not null)
I am creating a table on SQL Server. One of the columns in this new table contains whole integer as wells as decimal values (i.e. 4500 0.9876). I currently have this column defined as Decimal(12,4). This adds 4 digits after the decimal point to the whole integers. Is there a data type that will have the decimal point only for decimal values and no decimal point for the whole integers?
I would like to cast (convert) data type decimal(24,4) to decimal(21,4). I could not do this using standard casting function CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable) because of the following error: "Arithmetic overflow error converting numeric to data type numeric." Is that because of possible loss of the value?
In my environment always on is there. Today I observed that primary server fail over to secondary server .now the secondary server acting as primary role.
Can I know when is fail over is happened and who did the fail over. Is there any script to find this?
I wanted to convert a dataset from vb.net (2.0) to an .XLS file, by MS Jet. My national standard is using decimal commas, not decimal points for numbers signing the beginning of decimal places. But the MS Jet Engine uses decimal point,in default. Therefore, in the Excel file only string formatted cells can welcome this data, not number formatted. How can I solve or get around this problem? (with jet if it possible) iviczl
I'd like to convert a Decimal value into a string so that the entireoriginal value and length remains intact but there is no decimal point.For example, the decimal value 6.250 is selected as 06250.Can this be done?
I am designing some reports for a German branch of my company and need to replace decimal point with a comma and the thousand comma seperator with a decimal point.
e.g. ‚¬1,500,123.00 to ‚¬1.500.123,00
Is there a property that I can change in the report designer to allow this to happen or is this something I need to convert in a Stored Proc.
I am having a file in which amount fields are given in a Packed Decimal format. Can anyone suggest me how I can read this data element from the file and convert it into SQL decimal datatype.
File is a fixed length. All the amount fields are given in Packed Decimal Format and rest of the fields are given in text format. How can i identify and convert only those packed decimals using SQL/.Net.
Example : a row in a file that has some packed decimals 158203508540188236252EUR20BZK0030 Å“& 20060715 0001010100010101

for the query i created i need zeros where ever the filed is blank. i have used count(acc) for selecting the count . can any one help me out with sample query. Thanks in advance
I have two tables, tblMTO and tblIMPORT_MTO. If I import an entire MTOinto the import table I want to create a delta from it (i.e. leave onlythe changed items). I have a view (simplified)SELECT dbo.tblIMPORT_MTO.ImportID, dbo.tblIMPORT_MTO.MTONo,dbo.tblIMPORT_MTO.Rev AS New_Rev, dbo.tblMTO.Rev AS Old_RevFROM dbo.tblIMPORT_MTO LEFT OUTER JOINdbo.tblMTO ON dbo.tblIMPORT_MTO.MTONo = dbo.tblMTO.MTONoNow to get all rows where old_rev = new_rev I also want all rows whereboth are null, is the best method to put ISNULL() in the view or toselect from the view using ISNULL in the criteria, e.g.select * from view1 where ISNULL(Old_Rev,0)=ISNULL(new_rev,0)or in the viewCREATE VIEW view1 asSELECT dbo.tblIMPORT_MTO.ImportID, dbo.tblIMPORT_MTO.MTONo,ISNULL(dbo.tblIMPORT_MTO.Rev,0) AS New_Rev, ISNULL(dbo.tblMTO.Rev ASOld_Rev,0)FROM dbo.tblIMPORT_MTO LEFT OUTER JOINdbo.tblMTO ON dbo.tblIMPORT_MTO.MTONo = dbo.tblMTO.MTONo;select * from view1 where Old_Rev=new_rev;
does sql server mobile 2005 support the isnull function? I'm getting an error when I try to use it and I don't know if it is becuase of using the isnull function or not, but when I run the same query on Sql Server 2005 it works fine.
I've seen lots of entries recommending the use of ISNULL in SQL WHERE clauses, e.g. in a search sproc where users can enter some or all parameters to search a table. Previously I would have used something like:SELECT * FROM MyTableWHERE (FName = @fname OR @fname IS NULL) AND(MName = @mname OR @mname IS NULL) AND(LName = @lname OR @lname IS NULL)So using the neat ISNULL syntax it could be updated to:SELECT * FROM MyTableWHERE (FName = ISNULL(@fname, FName)) AND(MName = ISNULL(@mname, MName)) AND(LName = ISNULL(@lname, LName))Having played around with this I stumbled upon a problem. If one of the fields, e.g. MName, is NULL then that clause will return false since MName = NULL isn't true and you have to use MName IS NULL. Did I miss all the caveats with using ISNULL in this way on fields that can contain NULL or have I missed something else?
I've got this query and it use to work or at least I thought it did. Could someone please help me with it. Thank you SELECT CID, CompletionDate, MarkedExport, CustomerName, EditUser, RouteID, WorkOrder FROM RouteCustomer WHERE (CompletionDate IS NOT NULL) AND (ExportDate IS NULL) AND (RouteID LIKE '%' + ISNULL(RouteID,@RouteID) + '%') AND (EditUser IS NULL OR EditUser = '' OR EditUser = @EmployeeID) AND (MONTH(CompletionDate) = ISNULL(MONTH(CompletionDate),@Month)) The problem comes with in the WHERE clause. What I wanted it to do is if the user did want to use a RouteID critera then the user would speified one else it wouldn't, and it was my belief that the ISNULL feature in SQL was the answer for that. same for the Month. I believe the EditUser is fine the way it is written. thanks to anyone that can help me with this. Rex
I have to display string "not assigined" when a datefield is null in a table. I am using like ISNULL(datefiled, "not assigned"), but I am getting following error Syntax error converting character string to smalldatetime data type. Is there any way, I can acheive desired result. Please help
To give you a little background, there is a CRM system with SQL server as its back-end. The CRM uses a view in SQL Server to list all the communications a user has had with his client over any given interval of time. Now there is a requirement to add a new column in the view that tells a user if the communication was filed in automatically or if it happened overnight via an automated archive manager process. I have achieved this using an expression field which is based on the comm_url field in the communications table in database.
example:
create view vCommunications as select col1, col2,...,case when comm_url is null then 'Manually filed' else 'Automatically Filed' as Filing from Communications
alternatively, this can also be achieved by the following:
create view vCommunications as select col1, col2,...,isnull(comm_url, 'Manually Filed') as Filing from Communications
Now my question is, given that there are many rows in the communications table, which of the above two expression fields will be more efficient in performance i.e. CASE versus ISNULL. I've checked a lot on google but I haven't been able to come up with a concrete answer.
Hey, I'm taking an intro SQL Server class, and I have a pretty simple homework assignment. We were provided with a DB and asked to write several SELECT statements. However, I'm stuck up one of the questions. Here is the question: 12.Create a SELECT statement that displays all employees and their Qualifications. Display that individuals with no Qualifications as having ‘NoQual’. Hint: Use a function to determine this ‘empty’ field using ISNULL.
Here is what I have:
SELECT FNAME + ' ' + LNAME AS 'Employee Name', ISNULL(QUALID, 'NoQual') AS 'Qualifications' FROM EMPLOYEE, QUALIFICATION WHERE EMPLOYEE.QUALID = QUALIFICATION.QUALID;
However, I do not get any results that have a NULL value in the QUALID column. Here is the code for the DB:
INSERT INTO position VALUES (1, 'President'); INSERT INTO position VALUES (2, 'Manager'); INSERT INTO position VALUES (3, 'Programmer'); INSERT INTO position VALUES (4, 'Accountant'); INSERT INTO position VALUES (5, 'Salesman');
INSERT INTO emplevel VALUES (1, 1, 25000); INSERT INTO emplevel VALUES (2, 25001, 50000); INSERT INTO emplevel VALUES (3, 50001, 100000); INSERT INTO emplevel VALUES (4, 100001, 500000);
INSERT INTO qualification VALUES (1, 'Doctorate'); INSERT INTO qualification VALUES (2, 'Masters'); INSERT INTO qualification VALUES (3, 'Bachelors'); INSERT INTO qualification VALUES (4, 'Associates'); INSERT INTO qualification VALUES (5, 'High School');
INSERT INTO dept VALUES (10, 'Finance', 'Charlotte', 123); INSERT INTO dept VALUES (20, 'InfoSys', 'New York', 543); INSERT INTO dept VALUES (30, 'Sales', 'Woodbridge', 135); INSERT INTO dept VALUES (40, 'Marketing', 'Los Angeles', 246);
