Re: Insert record using DataReader - Database Discussion Boards

From memory, "Input Into" is a special command that is handled by directly by the ISQL program (and so is not understood by the database engine).

You might consider using running the Sybase BCP command - although you need to be careful of your %PATH environmental variable if you have MS-SQL installed (because the MSSQL client tools has a DLL that clashes). Other possibilities include using MS-SQL's DTS packages.

Hope this helps.

Loading Excel to DataSet

Hello,

I am trying to load Excel data to DataSet, (using OldDb... classes). Unfortunately during Fill method of OleDbDataAdapter OLE looses part of my data. I think that is becouse before loading data JET 4.0 makes some assumptions about what type columns in the sheet are. I think, this is why, when in a column there are some numbers and some strings I can read only numbers or only strings - it depends on which is more frequent.

Is there any way I could make OleDBDataAdapter (or JET driver) to read data as string!

Best regards

Leszek

Hi there. In your connection string, you can use the IMEX import mode - IMEX=1. Something like this:

string sCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\SomeExcelWorksheet.xls;"
            + "Extended Properties=\"Excel 8.0;IMEX=1\"";

You can look at this Microsoft Support document[^] for a more thorough description of the IMEX option.

Asscess and linked tables

14-Oct-04 20:52

Hi !

My application (developped in C++) is using an Access database. The database is actually made of two '*.mdb' files, one being linked to the other with linked tables.

It works fine : I use one database, and I can make SQL queries including the linked tables from the other without any troubles.

My problem now is if I want to install my app on someone else's computer, the path to the databases is different, but the link is absolute. Thus, the linked tables are not found and my application doesn't work.

I know that with Access, there is a menu to update the path of the linked tables, but of course, I don't want to have to do it manually through the Access Application : I want to be able, from my app, to update the linked tables automatically.

Problem : I have no idea if it is possible to do that, and how !

Any help ?

Thanks !
Jerome

Insert record using DataReader

Anonymous14-Oct-04 11:46

Guys,

I have a stored procedure in SQL Server where I pass few parameters like username, email address etc. The stored procedure simply inserts these records into users table that has an identity column as ID. Finally I read the @@IDENTITY variable to read the ID of newly inserted record and returns it via an OUT parameter passed in the stored procedure.

Now question is if I have to call this stored procedure from my C# code, can I used DataReader for this purpose? What are the best practices?

TIA
Jixi

If you are accessing the newly inserted ID via an OUT parameter then you would use SqlCommand.ExecuteNonQuery().

You could alterantively return the newly inserted ID via a select statement and use a data reader if you want to. e.g. After the insert in your stored procedure you would put

SELECT @@IDENTITY As Identity

and you could retrieve that single value using a DataReader, but that is really a bit reduntant because that is what SqlCommand.ExecuteScalar() does for you anyway.

You need to either log in with an account that has permission to use SQL Server, or you need to set up the permission in SQL Server for the account you want to use.

I'm not really a fan of allowing Anonymous access to things in a business senario so I would suggest that you log in using an appropriate account. As you are accessing this through an ASP.NET application I am curious as to what your security settings are, if you check the box that says allow anonymous access then it will access resources through a special ASP.NET account.

search for a specific string in a stored procedure

hi

I have a very large database with several stored procedures. now, I need to find a stored procedure that does some calculation if that stored procedure has a string "MESSAGE"(just an example) in an IF statement somewhere down the procedure.

currently i am opening every stored procedure, doing a Ctrl+F for the above string and if i find it then that means i determine that this is the stored procedure that i will have to work with(change the calculation in it or some work)

so my question is that can i write something ... that will list me all the stored procedures which have a certain string contained in them??

I am new to sql stuff .. so please help me. this could save me a lot of time.

thanks

sp_helptext is a system stored procedure which takes the name of a stored procedure and then lists it. This code will list all your stored procedure names:

SELECT name FROM sysobjects WHERE type = 'P'

So all you need to do is make a table of the names, then go through it, calling sp_helptext to get the stored procedure text, and if your text matches, return the name.

hi christian

thank you for the reply. the thing is that there are 120 stored procedures in the database and I need to know which stored procedure's BODY contains the string 'MESSAGE', etc. some stored procedures are almost 4 pages long.

I am not searching for the stored procedure named %Message%. but searching for a stored procedure whose body contains the string.

can you please give me a code sample ?

thanks

Sure - so you need to use the code I provided to build a table that has a list of stored procedure names. Then you need to use that tempory table to step through the stored procedures, IN CODE, retrieving the text of the stored procedures, WHERE the text is LIKE %Message%.

its_skar wrote:

That's why I gave you the name of the stored procedure that returns all the text of the procedure. You also need to get the names, otherwise, how will you know where to get the text from ?

Disable ODBC default settings

Its due when12-Oct-04 20:30

Its due when

12-Oct-04 20:30

Quoting from MSDN:
"SQL Query Analyzer uses the SQL Server ODBC driver, which, by default, sets these SQL-92 options on: SET ANSI_WARNINGS, SET ANSI_PADDING, and SET ANSI_NULLS. Any errors returned are formatted as ODBC errors rather than DB-Library errors."

Is there any way to modify these options so that they are not the default?
Thanks!

You don't specify what your program is written in, so I'll assume it is a language that targets the .NET Framework.

You change the connection string property of the SqlCommand object so that the part of the string that reads "Server=(local)", changes the (local), or 127.0.0.1 or whatever to the IP or machine name of the remote server.

Do you want to know more?

You can't, simple as that. A PalmIII is only able to connect via a conduit, I believe, and certainly there is no support for SQL databases on the Palm.

Why do you need the network angle ? Just install MSDE or SQL Server on your laptop, the system will be agnostic to where the db comes from anyhow.
