Can't Change Datatype???
Jul 20, 2005
Hello all,
First of all, I must state that I'm new to SQL Server, but have been a
long-time software guy for quite some time. Please excuse the potential
simplicity of the solution to my problem.
I create a blank database (TestDB) under my server machine (SQL Server 2000
Standard)... I then create a new table (Run_Number) with only one record in
it.
Field(1): Next_Run_Number (bigint), identity w/ seed 1 and increment 1, no
nulls, PK
I can successfully save this new table to disk and everything seems fine...
problem comes up when I go back into the table and change the datatype from
(bigint) to (int). I try and save changes and I get the following error
prompt:
'Run_Number' table
- Unable to create index 'PK_Run_Number'.
ODBC error: [Microsoft][ODBC SQL Server Driver]Invalid cursor state
I've checked and there's plenty of disk space available and the dbase is set
to grow by 10% as necessary. Any ideas what could be going wrong? I'm able
to successfully make this change on my other machine running SQL Server 2000
Personal. Thoughts?
TIA!
-J.C..

Hello,How do I change the datatype of a column in a CSV file. Preferably in the select statement (apparently Cast, Convert, & Replace functions don't work when selecting from a CSV). I have a page where users upload their CSV files to and then I use SQLBulkCopy to insert all the records into my sql table. The problem is with columns of money data. EX: "$2,000" >> 2000The CSV file interprets the "$2,000" as a string of text. How do I convert it to a decimal so I can insert it into my sql database?

I am running Microsoft SQL Server 2012.
I had created a database named "Company-Data" that contains a table named "tblStock". This table contains several columns such as ID, Product, Quantity. The datatype for the column "Quantity" is INT.
I had entered 100 records to the table, now I want to change the datatype for the column "Quantity" from INT to MONEY.
How can we do this without loosing the data that has been entered the the column previously.

Hello,
I would like to change the datatype on a particular column from varchar to bigint across 100's of tables within a database.
I have the command ready which is:
ALTER TABLE tablename ALTER COLUMN columnname BIGINT
The problem happening is that it seems there are constraints across all the columns in every tables.
The error message is:
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF__tablename__columnname__0ABD916C' is dependent on column 'columnname'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN columnname failed because one or more objects access this column.
I understand that if I delete this constraint, then it will let me modify the datatype of the column, but since there are tons of them and they are randomly named, how do I achive changing the datatype across multiple tables in bulk.

I am trying to replace the value of a column in a derived column component, but it will not let me change the datatype.
It has decided that the column is a float, which is wrong.
How can I change it to the correct type?

Hello,
I am trying to extract from some strings like the following strings the number and order them by that number:
Box 1
Box 2
Box 3
Box 20
Box 21
...(and so on)
The problem I am having is that I already extracted the number using
Substring([field],[starting position],[lenght])
but the output seems to be in a string format, so the order is not in an ascending order.
Thanks for any suggestions.

I have a data source that I access via odbc in a DataReader Source component in SSIS. I can access the data fine. However, I am having problems with certain fields that are numeric (specifically home prices ranging from 100,000.00 to 99,999,999.00). In the advanced editor for my data reader source under the input and output properties tab, in data reader output under the external columns and output columns, these fields for some reason default to numeric data types with a precision of 4 and a scale of zero, not large enough to hold the data that is coming in. This causes errors that make the data come in as null (after i specify to ignore the errors).
I can change the precision and scale to 18 and 4 in the external columns, but when I try to change the datatype, precision or scale in the output columns I get the following message:
Property Value is not valid.
The details are:
Error at Import DataReader Source: The data type of output columns on the component "DataReader Source" cannot be changed.
Error at DataReader Source: System.Runtime.InteropServices.COMException (0xC020837D)
at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostSetOutputColumnDataTypeProperties(IDTSManagedComponentWrapper90 wrapper, Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
Any help is greatly appreciated.

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

We ran into weird/interesting issue with below details.
Version: Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64) Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200):
We are using SQLCMD to run DDL script on our product database in below order. That script has below content.
step # 1 - database collation change (case -sensitive) statement as very first statement of the script
step # 2 - Actual DDL SQL statements
step # 3 - database collation change back to original (case insensitive)
When we execute all above 3 steps in single script using SQLCMD on our test_server#1 , it is successful but when same is being implemented on test_ server#2 , it is failing.We ensured that there is no other user accessing the db and setting on both the server are all default/basic. Separating out all 3 steps in 3 different script working fine. This is only problem when we combine them into single script and fire it using SQLCMD. If it is something related to session/transaction then we should hit same issue on our test_server#1 server as well but that is not the case.test_server#1 and test_server#2 has exact same database/data, just two different physical machine & SQL Server instance.

I have a USERS database table with a column called IsValidated. It identifies if a user has been validated.
I'd like to know which datatype would be the most efficient for this column.
Our DBA made it a varchar(1) column. Would using int be better?
Please advice.

I have a message box or multiline textbox on my form and I am storing into an SQL DB. I currently have it as a VARCHAR, but that doesn't seem to store the carriage returns. Do I have to store them as a nvarchar, text, ntext or something else to make the returns show? I am pulling them out of the DB and showing them in a label where I replace the with a <br>.
tempMessage = Dr("Message")
message.Text = tempMessage.Replace("", "<br />")

Over the years I have always used the decimal(18,0) as the datatype forprimary keys. Aside from the number of significant numbers involved,would BigInt type be better for performance or is decimal(18,0) still okay.--Don VaillancourtDirector of Software DevelopmentWEB IMPACT INC.phone: 416-815-2000 ext. 245fax: 416-815-2001email: Join Bytes! <mailto:donv@webimpact.com>web: http://www.web-impact.comWeb Impact Inc. <http://www.web-impact.com>This email message is intended only for the addressee(s) and containsinformation that may be confidential and/or copyright.If you are not the intended recipient please notify the sender by replyemail and immediately delete this email.Use, disclosure or reproduction of this email by anyone other than theintended recipient(s) is strictly prohibited.
