Mysql dateadd query problem

All,

I have been toying with this query for some time now to no avail. I need to run a retention report on sales that canceled within 30, 60, 90 days of the original sale date. My query is below. Could someone please help me in the right direction as to why it doesn't work? The error I get is below the query

<br />
SELECT count(*) FROM db.orders<br />
where date_entered between "2007-08-01" and "2007-08-31" and cancel_date <= date_add('day', 30, date_entered)<br />

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '30, date_entered)' at line 2

Thank you very much!

Reference for DATE_ADD in MySQL 6.0[^].

I think the correct syntax would be DATE_ADD(date_entered, INTERVAL 30 DAY).

MySQL is not SQL Server and they do not necessarily use the same syntax for features that both implement. There is a common but very limited standard SQL syntax; many databases support most of SQL-92, but usually not all of it.

Thank you so much! That finally got it working. I knew there was a difference in mysql, but I just couldn't figure it out. Usually its the simple things that fix these problems. Thanks again mate!

SELECT works fine when I execute directly but fails in stored proc

Hi all. I'm getting a strange error against an Oracle 9i database. I have a stored proc and one of the cursors I'm using has the following SELECT;

<br />
	SELECT ref_no_rev, ref_no FROM<br />
         (<br />
            SELECT REVERSE(ref_no) AS ref_no_rev, ref_no<br />
            FROM (<br />
                  SELECT DISTINCT ref_no<br />
                               FROM itm_table<br />
                              WHERE ref_no IS NOT NULL)<br />
         )<br />
         ORDER BY <br />
         	ref_no_rev<br />

And when I execute it directly against the database from the TOAD editor, it works fine and returns what I want. But when I try to access the cursor in code like so;

<br />
OPEN cur_ref_nos_with_rev;<br />
FETCH cur_ref_nos_with_rev BULK COLLECT INTO col_ref_nos_with_rev;

If falls over on the FETCH, giving me ORA-01001 - Invalid Cursor.

Anybody have any ideas?

It's not because you have two fields in your select statement and only one variable in your fetch statement? (Oracle not my strong point).

Re: SELECT works fine when I execute directly but fails in stored proc

Mel Padden14-Dec-07 3:51

Mel Padden

14-Dec-07 3:51

The variable in the FETCH is a strongly typed associative array of rows returned from the query. The table itself contains 500,000+ rows, this query returns about 300,000, so I want to grab it all in one go, do some processing, and then bulk update the database. That's why I'm using the BULK COLLECT. It's part of a proc that writes about 9,000,000 updates, so performance is an issue.

Doh and thricely doh. It was due to a brain fart in the piece of code preceding the fetch. My fault.

Thanks for trying to help all the same.

This article[^] shows how to query an Excel speadsheet using the Jet OLEDB Provider. Once you have your data in a DataTable, you can iterate through it and run INSERT queries against your SQL Server database. The code is in C# but it should be trivial to convert it to VB.NET.

If your spreadsheet is particularly large, you may want to consider using DTS/SSIS to perform the import and trigger the operation from your .NET code.

Importing NULLs Instead of Actual Values

Bryan Bradford13-Dec-07 9:58

Bryan Bradford

13-Dec-07 9:58

Need some help with an import problem.

Got a database (SQL 2005) with a column that has a type of VARCHAR(100) and I am trying to import data from an Excel file using ADO.NET and stored procedures.

Here are some examples of the values I am tyring to import:
0
81752646
TS:2923137:ABC
WELCOME_HEAD:H:1:2:B
etc...

I am getting the actual values to import for the ones like 0 and 81752646 but for the others it is importing a NULL value every time.

I have done the registry fix for mixed data type and it makes no difference.

Anyone have any idea how to fix this?

Thanks,
Bryan

Re: Importing NULLs Instead of Actual Values

I guess that you have altered the TypeGuessRows registry setting. Have you included the element IMEX=1 in your connection string? This informs the driver that columns where the data is of an indeterminate data type should be treated as text.

The following text is from KB article 194124:

NOTE: Setting IMEX=1 tells the driver to use Import mode. In this state, the registry setting ImportMixedTypes=Text will be noticed. This forces mixed data to be converted to text. For this to work reliably, you may also have to modify the registry setting, TypeGuessRows=8. The ISAM driver by default looks at the first eight rows and from that sampling determines the datatype. If this eight row sampling is all numeric, then setting IMEX=1 will not convert the default datatype to Text; it will remain numeric.

Adding this setting as well as modifying the registry should produce the desired results.

I have the TypeGuessRows set to 0. I'll have to go back to the code to see if I'm using the IMEX = 1.

Database redesign advice, please.

I have been asked to redesign the database my company uses for it's web applications. The old database is SQL Server 2000 and I am updating it to 2005.
The old db has many problems, not the least of which is that it simply "evolved". As each new developer worked on it they added tables to do whatever they needed to do instead of finding tables that already contained the data they were operating on. I currently have in excess of 250 tables, a quick search of the pages in the website reveals that at least 60 of these tables are not used. What I need to do is find what data is used and what data is repeated in different tables under different names.

I would appreciate any advice, where to find articles, etc., on how to go about this redesign while minimizing the time I have to spend. Please, point me to where I can find strategies, techniques, etc., to optimize my efforts.
Thanks
Jim

Firstly you need to work out how important your existing data it. How much needs to be retained, etc.

Then you can decide whether you are going to be massaging the existing schema (yuck) and keeping all the data, or you have free reign to redesign the entire thing from scratch.

Try making an entity relationship diagram off the existing schema (or business process - as the existing schema is probably crap) and see what is left out or missing.

Then get signoff on the ERD, and enjoy a nice new schema that makes sense. Try and follow some of our tips in our quick reference sheet under Active Record Friendly Databases - it will give you a much wider choice in selecting your data layer tool.

Thanks for the advice Mark. After several days of working on the old database I went to my manager and told him it was going to be too much work to simply rework the old data into a new database so now I get to build from scratch.
What url for Active Record Friendly Databases? I can't find the page.

Its in the Diamond Binding Quick Reference Sheet, in the downloads section.[^]

While following those tips isn't mandatory, it will certainly make your object model a lot more intuitive - especially if you use a tool like Diamond Binding to handle your data layer (give it a try!).

Hi,

im new to using SSRS reports. I created a report and tried viewing it in Firefox, however it is not displaying correctly. The width of the whole report is shrunk on the left of the page. Arents SSRS reports compatible with Firefox browsers?.. or is there something im missing here?
I'd appreciate some help in this...

Thanks

The SSRS documentation states that reports can only be expected to render correctly in Internet Explorer. A known workaround is to place a hidden textbox on your report that spans the entire page width.

Hi guys,
I've a problem opening a CRecordset object on an Oracle database
using the Microsoft ODBC for Oracle.
The query I'm using is something like the following:

SELECT MAX(OBJECTID) FROM MY_TABLE

the CRecordset object is a dynaset.

When I execute the code I get an error from the ODBC driver
tha says that is not possible to use keyset cursor in join
operations with distinct, union, intersect or minus conditions
or on read only dataset.

Can someone tell me how to solve the problem ?

Thanks a lot !
