I hope someone can help me.
I am running a visual basic program which creates a recordset based on a stored procedure. No matter what cursor type I set I always end up with a static cursor on my recordset. I think the stored procedure is over-writing the cursor type. As I know very little about TSQL, I don't know how to fix this.
Any Ideas?

I consider CURSOR and TABLE as data types but some one has argued that these are database objects.

I've been writing this stuff for a while, and can't seem to come to the
conclusion of how I should be retrieving data and assigning this data
to variables.
Since i'm using SQL Server, I'm convinced that I should be using the
datareaders GetSqlDouble (or whatever) function, but this would mean i
need my local variables to be one of the SQL types. The problem
with that is, that there will have to be lots of conversions done by me
to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order
to retrieve them correctly (Null values included), I need to retrieve
them with GetSqlDateTime(), then when it comes time to display the date
in a table, i must first check for nulls, then convert to a
string. This seems to be very cumbersome. Would I be better
off just using GetDateTime(), and the .ToString method, and ignoring
Sql Types all together?
so, basically, how are you guys using your sql server data? with
the supplied sql types, and doing all of the post-processing work
manually? I feel like i'm having trouble conveying my
issue...hopefully someone knows what i mean....i'd just like some
direction to save trouble in the long run, since i feel like there's
got to be a better way...
Confused!
Thanks,

In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static

             while @@FETCH_STATUS=0

In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

Hi,
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
thanks.

I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim

So i have table MyObjects And ObjectParameters-OP
In the table OP i want field for Parameter Type(Type)... now i using type Varchar(63) and then i need for parameters of money type, i will get it by SELECT * FROM ObjectParameters WHERE Type = 'money'...
at the sql.ru i got an answer, where they suggest me using type "sysname", in MSDN i have found that it is equivalent nvarchar(128), i a cant find any differences between my solution and sql.ru solution.
AND main question is.. can i using ID for my types from View sys.types, And can i be sure that it will be the same ID in another version SQL Server (like 2000, 2008) or another installation of SQL Server for same type...
sorry if i have misstakes in my english...

I have a really dumb question regarding SQL data types. I have a couple columns in a table that are specified as MONEY. These columns are being read from my web app and displayed on the website for reference when filling in other information.
My problem is that when it is displayed on the website it give four decimal places instead of two. For example I want it to report $33,000.29 but what is actually displayed is $33,000.2965.
How can I set up either SQL or my web app so that it only displays the two decimal places? I've looked into changing the datatype already but SMALLMONEY and MONEY have the same type of decimal values.
Thanks!

If not is there a way to convert the encoding before I insert? Or any other ideas anyone might have. Thanks!

I'm just getting used to using SQL 7 Database and am looking for some recommendations on what DATA TYPES to use when designing tables.
The site I am working on now uses cold fusion to enter, update, and insert mainly text and articles. Now the problem with the articles is that some of them are pretty big. And when inserting or updating them, if they go over the limit of characters I get an error.
I know in access I used to use the data type "MEMO" and be able to put a large piece of info in that field.
What's the equivalent for SQL server databe?
What are the most used/common or recommended data types that should be used when putting tables together?

Hello, dear Friends!
My situation is a following:
I have some not big databases with only English data and some conteining data in Hebrew.
My question is: May I manage two collation types- meaning the database collation type will be for example some kind of Latin and some databases' collation will be in Hebrew.
If you have any experience of managing DB's in two absolutely different languages (Japanesse, Russian, Chinesse, Arabic with English) please tell me about it.
Best regards.

Hi,
I am pretty new with SQL and was dabbling in a test database that is linked with a software application.
I made a change to a table - Lets call this (Table1).
Table1 has a multiple columns.
Column1 is defined as numeric(9)
Column2 is defined as varchar(20)
In this case, I wanted to make all values in Column2 = Column1 that did not have a value defined so I ran the following query:
update Table1 set Column2 = Column1 where Column2 = ''
This took effect but the particular software application doesn't recognize these values because they are the wrong data type.
How can I convert all data in a column to varchar(20) if it is another data type (i.e. in this case numeric(9))?
I've tried in Enterprise manager to redesign the table and adjusted the length to 21 and then back and saved it but this did not work. I was looking at Convert and Cast functions but don't know how to write one to accomplish what I need to do here.
Half of the data in Column2 is varchar(20) and half is numeric(9).
I want all to be varchar(20).
Thanks,
