Field Datatype Conversion In SQL Server 7
Apr 30, 1999
Can anyone tell me how to calculate datatype conversion times in SQL Server
7? I have a varchar (15) field that I tried to convert to integer using
the table design GUI in Enterprise Manager. The table holds about
72,000,000 records about 1k apiece in size.
It's been running for about an hour now with no seeable results. In
Performance Monitor I don't see any page reads happening, so is this
indicative that the process died? Enterprise Manager is no longer
responsive - even if I open another session.
I'd like to know how long I can reasonably expect this conversion to take.
Also, how can I abort this request safely if I want to?
Thanks for any insights.

Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,
B

Hello!
I am trying to run a query on an SQL-server database:
SELECT (Left(Comments, 20)) As shortComment FROM myTable
The Field Comments is a Text field (datatype is text), and I can't get the LEFT function to work with this datatype...
How can I bypass this problem? Can I convert the commentfield to varchar in the QUERY?

I am getting a "Syntax error converting the varchar value '10,90' to a column of data type int." error when I run the following procedure:
@myList varchar(200)
SELECT column1
FROM table1
WHERE table1.ID IN (@myList)
When @myList is a single value, I get no errors. However, when @myList is a comma separated list like in the message above, I error out. I am using SQL Server 2000.
How else can I build this list of IDs? Thank you in advance for your comments.

Dear All:
I am in the process of developing a code generation tool to generate automatically:
1- Business Layer objects
2- Object Layer objects
3- Data Layer objects
The code follows the same technique used in IssueTracker Starter Kit.
I faced somehting wierd today while trying to convert between SQL Data types to C# data types:
Check the image please, the problem is that, different value number is being given to each column type, by using both:
syscolumsn.type and syscolumns.xtype,
which one to use ? which is the best used to convert to C# ?
Are there any place where data types of SQL Server are being converted to C# data types ?
check the pic here please SQL DB
Thanks a lot

I am using DTS to import a DB2 table from the mainframe and export the table in text format to a shared folder. I want to convert two fields to a date format yyyy-mm-dd. RELSE_Date is in this format and Updtts is a timestamp coming from the mainframe. The text file is all vchar. In dts here is my query pulling from the mainframe
SELECT A.PROD_ORDER_NUMBER, A.DYE_SEQUENCE, A.STYLE,
A.COLOR, A.SIZE, A.STATUS_IND, A.STATUS_CODE,
A.QUANTITY_REC_DC, B.SHIP_OTFQ_QTY,
A.MRP_PACK_CODE, A.LABELS_PRINTED,
date(A.RELSE_DATE) as RELSE_DATE,
date(A.UPDTTS) as UPDtts, A.LOCATION
FROM DB2.WP1_PO_CUST_REQ A,
DB2.WP1_DYE_LOT_REQ B
WHERE A.PROD_ORDER_NUMBER = B.PROD_ORDER_NUMBER
AND A.DYE_SEQUENCE = B.DYE_SEQUENCE
AND A.STYLE = B.STYLE
AND A.COLOR = B.COLOR
AND A.SIZE = B.SIZE
AND (A.PROD_ORDER_NUMBER LIKE '__K____')
When I parse the query it accepts it. When I run the DTS I get an error stating (SQL STATE 220077 SQLCODE -180) The sting representation of a datetime value has invalid syntax. Does anyone have a suggestion on how to convert these fields before the text file is exported or another output format that is similar to .dat in comma delimited format? Thank you.

Have a simple question -
Will it be possible to convert a varchar data type column (having values that are numbers or null only) to a numeric data type column having the number values and the null values not being replaced by 0.
Col A Col A
(varchar) (int or numeric)
123 123
124 124
NULL 0 <expected blank>
125 125
I tried using CAST(Col A as int) and it converts the NULL to 0. Will
CAST(ISNULL(ColA,'') as int) work? The reason for this requirement is the value 0 will give different meaning to the data. Any insights will be appreciated.

Hi ALL!
I have a table named 'Table1' which contains a column 'Name'.
The data type of column [Name] is varchar(50).
When i try to change its datatype to binary by trying following code
ALTER TABLE Table1 Alter Column [Name] Binary(5000)
It gives following error.
" Creation of table 'bp_MAIN' failed because the row size would be 10021, including internal overhead. This exceeds the maximum allowable table row size, 8060. "
So, how can i change the datatype of this column ?
Regards,
Shabber Abbas.

here is my problem:
i have a variable @sid_x as binary(16) = 0x4CF254AB0BA5D411AA3E00508BC5C413
and i want to use it as argument in sp_addlogin statement.
select @sqlcmd = 'sp_addlogin "test", @sid = ' + @sid_t
/* this doesn't work, because @sid_t is binary... */
select @sqlcmd = 'sp_addlogin "test", @sid = ' + convert (char (20), @sid_x)
/* this doesn't work either, because it doesn't convert to binary text */
my question, is there any way i can get @sid_x in follow text format
0x4CF254AB0BA5D411AA3E00508BC5C413 ?
Thanks a lot!

Exception in one of the stored procs:
Conversion failed when converting the nvarchar value to datatype int. After moving database from 2000 to 2005.
Using backup and restore.
Note I had the same issue after restoring the production database on my local server SQL2000->SQL2000.
The problem was solved by restoring master and msdb from the production. But I can't do this on the SQL2005.
This is not a collation issue as I have ensured collation is the same on all databases including the system ones.
The database in question makes extensive use of user defined data types (Which I have recreated on the destination server).
Can anyone please help?

Hi All,
Here is a description of the issue I'm facing about decimal datatype conversion from DB2 to SSIS throught Microsoft OLE DB Provider for DB2.
I first discovered it when I tried to use a LookUp trans. and selected a decimal typed field. I was unable to validate it and clicking the OK button threw the error copied below:
TITLE: Microsoft Visual Studio
------------------------------
Error at Data Flow Task [DTS.Pipeline]: The "output column "MFIXFRA" (317)" has a value set for length, precision, scale, or code page that is a value other than zero, but the data type requires the value to be zero.
------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC0204019 (Microsoft.SqlServer.DTSPipelineWrap)
------------------------------
BUTTONS:
OK
------------------------------
Some workarounds on this issue led me to two other strange behaviours:
- If I create a dataflow task to perform a raw copy of a DB2 table to a brand new table in SQLServer destination (by clicking "new" instead of choosing an existing destination table), generated "create table" script for decimal fields is quite different from source table. For example, a source field declared Dec(15,2) is translated as Dec(29,5), and so on.
- Quite same behaviour if I try to derive a column using as derived column trans. If the source column is a decimal, it's scale and precision are interpreted ramdomly.
Any idea welcome
André

I have a field with a datatype of text. In SQL it looks like:
Body(text,null)
This field is used for notes. For certain records users will enter a date.
20150425
I'm looking to do a select statement that will grab only those records with a date and make them an int field. This doesn't seem to work.
select convert(int, body)
from b
where left(body,2)='20'

Is there an AutoType Datatype for Date field. just like the Identity property for an ID field.
It increments by 1 for each new record.
The same way if i add a record to the table can it automatically put todays date or date and time for the field date created in my table.
The reason is i am uploading the record from xml file(Using SQLXMLBULKLOAD) so i dont have a chance to mention on the front end code or in the XSD file.
Any help would be greatly appreciated.

Hi everyone.
I have a field that is image datatype. That table is included in a snapshot replication. When I try to update that field - on the publication server, which is the same as distributor server - if the image is too big (in size), an error message appears. When I try to update with images that has less size it works. If I take out the subscriptions, it works for every image size.
Any ideas?

Hi, I've read conflicting articles on updating an ntext field in acolumn.My ntext field will exceed 8,000 characters (typically twice that size-- but just a text string).One article (I think from MicroSoft) said you could NOT use ntext inan UPDATE statement, but I've seen examples from other people usingit...but don't know if it's related to the size/characters issue.Is this true or not?Thanks very much...Kathy

Hi there,
I have been hired for a couple of weeks to investigate the performance of a sql server 2000 system.
One of the things that strikes me is that all the Primary key (identity field) fileds uses an decimal(18,0) as it's datatype.
An decimal with a precision of 18,0 takes 9 bytes for each column, while an int takes only 4 bytes and and bigint 8 bytes.
Many tables aren't that big, so the values will fit in an int datatype.
1. Is iot a good option to change the decimals columns to an int column ?
2. Many of these columns are indexed by a clustered index. Can the decimal datatype be a performance issue ?
3. sometimes they have deadlocks due page splits. Can this by reduced by changing the data types, while more data fit's into an page?
Thanks in advance,
Greetz,
Patrick de Jong

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.

Hello, I would appreciate any suggestions
I've got a datetime field that I'd like to store as just the date without the time component, but still to keep it defined as a datetime field. I ran this update statement but this conversion isn't working. Conversion to char gives me what I want but I need to keep the field as a date datatype if possible.
Thanks :)
update
<table>
set
<column>=convert(datetime,convert(char(10),hire_date,101)) )

Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
