Sp_prepexec And Compatiblity Mode 7: Float Variables Comparing To String Field Fails
Jul 20, 2005
I have a statement that works in compatibility mode 8 of SQL Server
2000 while it fails in 7:
declare @P3 int
exec sp_prepexec @P3 output, N'@P1 float', N'select custname from
customer where custnr = @P1', 12600034
custnr is a varchar(15). As long as the float p1 is less than
1,000,000 the query returns correct results, but as soon as p1 is
equal or greater than 1,000,000 the resultset is empty. I could
figure, that above 1 million, sp_exec converts the float into
exponential format and compares this format to the string containing
fixed format values. As said above, in mode 8 the statement returns
correct results above 1,000,000.
Please don't ask me, why we use float variables - I don't have any
influence on the statement - we isolated the statement with the
profiler.
We are also currently dependent on the compatibility mode 7.
I would be very grateful if you have any ideas, help or other issues
for me.
Thank you,
Peter

Hi,we found some strange behavior when operating with floats and round().The following simplified statement reproduces the problem.select 6.56 - round(convert(float, 6.56), 2)from sysusers where name = 'public';===========-8.88178419In "real world", the floats are not literals, but float fields in tables.I could figure, that 6.56 - 6.56 will result in something like 0.00001,but -8.88178419 is beyond my imagination.The same statement without round results in 0.Has anyone any clue on this?Regards,Peter

HiThe scenario:The price of products are determined by size.I have a Prices table that contains 3 columnsWidth Length and Price.User inputs their own width and length values as inWidth and inLength.It is unlikely that these values will exactly match existing lengths and widths in the price table.I need to take these User Input values and round them up to the nearest values found in the Prices table to pull the correct price.What is the most efficient way of achieving this?Thanks for your time.C# novice!

I am running into some issues with conversion and would appreciate someone who can help on this.
I need to roll up a column which contains numeric (float) data but it is stored in a varchar field.
I was trying to do the following (please note that Activity field is varchar(50) in MyTable):
SELECT CONVERT(float, (NULLIF(Activity,0))) from MyTable
and i get the following error.
Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value '-39862.8' to data type int.
I even tried with case statement (as below) but still got same issue.
SELECT CASE ISNUMERIC(NULLIF(Activity,0))
WHEN 1 THEN
CONVERT(float, (NULLIF(Activity,0)))
ELSE 0
END
from MyTable
Thanks,
Ashish

I have a table with three columns: UniqID, Latitude, and Longitude.
I need to write a query to identify when the latitude has more than 6 decimal places past the decimal. Same with Longitude. Values in these attributes can be a negative number. These fields are FLOAT.

I have a field called PPH and this field type float. so, this field could be null, 0.0, or values. I am using case statement:
[PPH] = case when h.HoursFloat = 0 then 0 else
round(s.Pledges / h.HoursFloat,2) end,
I am trying to add where if h.HourFloat is null then 0 but, it does not work. I have tried different ways such as
[PPH] = CASE isnull (h.HoursFloat,0)
when 0 then 0 else ....
How to add another condition to check on null then 0.

Hi,
When i try to insert a value in to a field of datatype float(8), it is storing the wrong values(approximate values).
For example, if i try to insert 2.62 , it takes it as 2.6200000000000001
But i can see the correct values displayed in the frontend.
Heard that there is a fix available for this issue.
Could any of you help me in getting the details about that fix?
Thanks in advance.

I have this problem of inserting my query into database field. My code is as of below.
The @AVERAGESCORE parameter is derived from
Dim averagescore As Single = (122 * 1 + 159 * 2 + 18 * 3 + 3 * 4 + 0 * 5) / (122 + 159 + 18 + 3 + 0)
and the value returned is (averagescore.toString("0.00"))
However, I have error inserting the averagescore variable into a field of datatype float during the transaction. I have no problems when using non transactional sql insert methods. What could be the problem?
Try
Dim i As Integer
For i = 0 To arraySql.Count - 1
myCommand = New SqlCommand
Dim consolidatedobjitem As ConsolidatedObjItem = arraySql(i)
myCommand.CommandText = sqlStr
myCommand.Connection = myConnection
myCommand.Transaction = myTrans
With myCommand.Parameters
.Add(New SqlParameter("@AVERAGESCORE", consolidatedobjitem.getaveragescore))
End With
myCommand.ExecuteNonQuery()
Next
myTrans.Commit()
myConnection.Close()
Catch ex As Exception
Console.Write(ex.Message)
myTrans.Rollback()
myConnection.Close()
End Try

Am converting varchar field to float and summing using group by and next inserting to varchar field(table).
while inserting float value it is converting to exponential ex:1.04177e+006 but if i execute only select statment actual float value will get display ex:1041765.726
My question is why it is converting while inserting ? and how to avoid it.
select query : SUM(CONVERT(float,(rtrim(REPLACE(REPLACE( column1, CHAR(13), ' '), CHAR(10), ' '))))) as AggregateValue

HiI have a problem trying to compare a string value in a WHERE statement. Below is the sql statement. ALTER PROCEDURE dbo.StoredProcedure1(@oby char,@Area char,@Startrow INT,@Maxrow INT, @Minp INT,@Maxp INT,@Bed INT
)
ASSELECT * FROM
(
SELECT row_number() OVER (ORDER BY @oby DESC) AS rownum,Ref,Price,Area,Town,BedFROM [Houses] WHERE ([Price] >= @Minp) AND ([Price] <= @Maxp) AND ([Bed] >= @Bed) AND ([Area] = @Area)) AS AWHERE A.rownum BETWEEN (@Startrow) AND (@Startrow + @Maxrow) The problem is the Area variable if i enter it manually it works if i try and pass the variable in it doesn't work. If i change ([Area] = @Area) to ([Area] = 'The First Area') it is fine. The only problem i see is that the @Area has spaces, but i even tried passing 'The First Area' with the quotes and it still didnt work.Please help, its got to be something simple.Thanks In Advance

Hi, I have the following query
SELECT *
FROM PABX
INNER JOIN LOGIN ON (PABX.COD_CLIENTE = LOGIN.COD_CLIENTE)
AND LEFT(LOGIN.TELEFONE1,3) = LEFT(PABX.NRTELEFONE,3)
LEFT JOIN AUXILIAR ON (AUXILIAR.ORIGEM=LOGIN.LOCALIDADE)
WHERE
pabx.COD_cliente = 224 and
SUBSTRING(PABX.NRTELEFONE,4,1) NOT IN ('9', '8', '7')
AND LOGIN.UF = RIGHT(PABX.LOCALIDADE,2)
AND LOGIN.LOCALIDADE <> PABX.LOCALIDADE
AND PABX.CLASSIFICA IS NULL
AND PABX.LOCALIDADE <> AUXILIAR.DESTINO
AND (BLOQUEADO = 0 OR BLOQUEADO IS NULL)
But It has a problem because when AUXILIAR.DESTINO returns null (it means there is no registry) the condition AND PABX.LOCALIDADE <> AUXILIAR.DESTINO doesn't work, like 'SAO PAULO' is different from 'NULL' but for my query no it's not even equal, and this condition ommit the results....how can I solve it ?
PS: Both auxiliar.destino and pabx.localidade is varchar(255)
Thanks

I have to write a where condition where i need to compare string with date
I have 2 columns FROMDATE and TODATE with datatype varchar(9)
The strings in the columns looks like YYYYMMDD+'1' or YYYYMMDD+'2' here 1 is Am and 2 is PM
i.e., 201401011 or 201401012
So I need to chop off last character before using them in WHERE condition.
Now I need to write a where condition like [if todays date is in between fromdate and todate columns then return rows.
if FROMDATE column is null it should take minimum date 1900/01/01 if TODATE is null then date should be 9999/01/01
The query i wrote is
select * from Table where ISNULL(SUBSTRING(VALIDTO,1,8),'19000101') > = getdate()
AND ISNULL(SUBSTRING(VALIDTO,1,8),'99991231') < convert(varchar, getdate(), 112)
but it shows no data...

Hi,
I run 2 steps viz with NORECOVERY and with RECOVERY in sequence as SQP jobs. The 2nd step fails some times. When it starts failing, I run full backup of the production server again and the 2nd step starts succeding. Unless I run the full backup the 2nd step keeps on failing.
What are the conditions which generate for [SQLSTATE 42000] (Error 3013) and how to tackle this problem.?
The 2 steps are :-
1.RESTORE DATABASE ARSYSTEM
FROM DISK = 'E:SQL backup from productionsql_full_backup'
WITH
Replace ,
MOVE 'arsystem' TO 'd:ardataarsystem.mdf' ,
MOVE 'arsystem_log' TO 'D:ARLOGARsystem' ,
NORECOVERY
GO
2.RESTORE DATABASE ARSYSTEM
FROM DISK = 'E:SQL backup from productionSQL daily diff back up'
WITH
Recovery
The status of the 2 steps is :
1 Executed as user: BPOTESTREMEDY
emedybackup. Processed 104480 pages for database 'ARSYSTEM', file 'ARSystem' on file 1. [SQLSTATE 01000] (Message 4035) Processed 1 pages for database 'ARSYSTEM', file 'ARSystem_log' on file 1.

Hi Guys, I am experiencing weird results
SELECT DSNew, DTTM, RQDT
FROM dbo.Feb
INNER JOIN DMSEFL
ON ACTR = DSNew
where cast(DSNew as varchar(20)) = cast(ACTR As varchar(20))
If I run the above query I get zero recs back.
If I substitute a Value then I get the desired results (ie. where DSNew = '93235500') or if I enter (ACTR = '93235500') or if I put (where DSNew = '93235500' AND ACTR = '93235500')
Can anyone suggest a reason why this is happening. I know the records exist on both tables I ran the query in Acess and got the desired resutls.
Thank you,
Trudye

Hi,
I'm running a profiler trace and I'm finding that sP_prepexec is running over 6 seconds everytime.
I looked at the SQL profiler and found out that the ODBC driver generates the update statements using sp_prepexec, I tried to run the update(without sp_prepexec) in Query analyzer, it returns the results right away.
Is there any known problems with ODBC driver about this or sp_prepexec related problems, if yes, how can I work around this.

Using the "set values" tab, I am trying to set the values of package variables to strings that contain spaces and/or dashes. If I run the package using the integrations services server, it runs perfectly. If I schedule the package on SQL Server agent, I get the following error.
"Executed as user: GBPSQLServer. Microsoft (R) SQL Server Execute Package Utility Version 9.00.3042.00 for 64-bit Copyright (C) Microsoft Corp 1984-2005. All rights reserved. Option "-restofstring" is not valid. The command line parameters are invalid. The step failed."
Looking at the command line generated by the SQL Agent interface, the value is quoted using double quotes like this:
/SQL "PackageName" /SERVER SQL1 /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /SET "Package.Variables[LogFolder].Value";"\remoteservernameinetpub he-restofstring
estofstring" /REPORTING E
It seems that the command line parser is not recognising the quotes, or maybe the slashes are throwing it off, or sql server agent is doing something funny to the command line before it executes it.
Anybody got any ideas?

I am executing a stored proc with in the Execute SQL Task using OLEDB provider. I am passing the data as
ConnectionType: OLEDB
Connection : to my database
SQLSourceType: Direct
SQL Statment : Exec mysp 'table1',OUTPUT,OUTPUT
In the parmeter mappings:
variable1--direction Output, datatype Long, Parameter name: 0
variable2--direction Output, datatype date, Parameter name: 1
The variable 1 is created as int32 and variable 2 is created as dattime.
When i execute the SQLtask, I get error:
[Execute SQL Task] Error: Executing the query "Exec mysp 'table1',OUTPUT,OUTPUT" failed with the following error: "Error converting data type nvarchar to int.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
What am i missing. I tried changing the data types adding the input variable also as a variable in the mapping. Nothing seems to work. Any ideas please?

Hi,
We are having problems with those two procedures, they are blocking other processes. I have seen sp_prepexec block another process for 5 hours, beforeI finally killed the process and the blocked process executed. Has anyone experienced behavior like this? What else can I do to troubleshoot this and determine the issue that is causing this? We could really use some assistance to determine the root of the problem.
Thanks.

What does are the rammifications in SQL 2005 of setting the compatibility level for a database to a lower level, for example SQL 2000 (80)?
Does this affect the underlying datastructure, the stored files on the server, or the indexes?
What effect does changing the compatibility level have? Does changing it cause the server to have to do any work to the indexs or table?
TIA!

I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits.
The mfg_start_date is delcared as a string variable
mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))
option 1
I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
With refresh_shipping_sched

We have some URLs within a bulk block of text some of which are very long. I need to identify rows where such urls exceed say 100 characters in length in amongst other text.So the rule would be return a record if within the string there is a string (without spaces) longer than 100 characters.

I can't take full credit for this. I want to share this with Jeff Moden who did the important research for this calculation here.
All I did was just adapting some old code according to the mantissa finding Jeff made and optimized it a little
Some test codeDECLARE@SomeNumber FLOAT,
@BinFloat BINARY(8)
SELECT@SomeNumber = -185.6125,
@BinFloat = CAST(@SomeNumber AS BINARY(8))
SELECT@SomeNumber AS [Original],
CAST(@SomeNumber AS BINARY(8)) AS [Binary],
dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Converted],
@SomeNumber - dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Error]
And here is the code for the function.CREATE FUNCTION dbo.fnBinaryFloat2Float
(
@BinaryFloat BINARY(8)
)
RETURNS FLOAT
AS
BEGIN
DECLARE@Part TINYINT,
@PartValue TINYINT,
@Mask TINYINT,
@Mantissa FLOAT,

@Bit TINYINT,
@Ln2 FLOAT,
@BigValue BIGINT
SELECT@Part = 1,
@Mantissa = 1,
@Bit = 1,
@Ln2 = LOG(2),
@BigValue = CAST(@BinaryFloat AS BIGINT),
@Exponent = (@BigValue & 0x7ff0000000000000) / EXP(52 * @Ln2)
WHILE @Part <= 8
BEGIN
SELECT@Part = @Part + 1,
@PartValue = CAST(SUBSTRING(@BinaryFloat, @Part, 1) AS TINYINT),
@Mask =CASE WHEN @Part = 2 THEN 8 ELSE 128 END
WHILE @Mask > 0
BEGIN
IF @PartValue & @Mask > 0
SET @Mantissa = @Mantissa + EXP(-@Bit * @Ln2)
SELECT@Bit = @Bit + 1,
