I'm trying to pass a table name into my mysql stored procedure to use this sproc to select off of different tables but it's not working...
this is what I"m trying:
CREATE PROCEDURE `usp_SelectFromTables`(
IN TableName varchar(100)
)
BEGIN
SELECT * FROM @TableName;
END
I've also tried it w/o the @ sign and that just tells me that TableName doesn't exist...which I know :)
I am having a hard time understanding how to change the width of columns when creating a table view.
I know you can set the width in pixels of a column but that is not what I want to do.
Say, for instance, I have 2 columns and want each column to take up half the screen. How do I do this without explicitly setting the pixels, so that my code can work on multiple screen sizes?

I have two tables with the same column definitions. I need to move (not copy) a row from one table to another. Before I go off and use INSERT INTO/DELETE (in a transaction), is there a smarter way?
SQL Server 2005
My table looks like this with duplicates in col1
col1, col2, col3, col4
1, 1, 0, a
1, 2, 1, a
1, 3, 1, a
2, 4, 1, b
3, 5, 0, c
I want to select distinct col1 with max (col3) and min(col2);
so result set will be:
col1, col2, col3, col4
1, 2, 1, a
2, 4, 1, b
3, 5, 0, c
I have a solution but looking for best ideas?

I'm struggling getting my head around the Django's ORM. What I want to do is get a list of distinct values within a field on my table .... the equivalent of one of the following:
SELECT DISTINCT myfieldname FROM mytable
(or alternatively)
SELECT myfieldname FROM mytable GROUP BY myfieldname
I'd at least like to do it the Django way before resorting to raw sql.
I am getting data from a query and processing it using Javascript in the xaction file.
Now I want to pass the processed data (a 2D array) down to a prpt where it will be used to generate graph and table.
What is the format in which Javascript would generate the data and how is it passed to and received by the prpt file from the xaction.
Thanks...
I have table and I want to swap the values from two rows. I have the rows IDs of the two rows.
Is there any query to do that? Here is an example. Before the query I have this:
row1 : 1,2,3
row2 : 5,6,7
After the swap I want this:
row1 : 5,6,7
row2 : 1,2,3
I don't want write it in .NET code because I think an SQL query is easier than that.

SELECT a.ID
FROM tblitem a
WHERE (4) = (select count(*)
from tblItem b
where b.id < a.id)
Thanks in advance
I try to draw a table on a panel in C# Windows Form by using GDI+. The problem is that when I minimize the application, my drawing disappears. How can I avoid this and why acting this way?
I want to confirm if the statement below is indeed true:
There is no way to specify a storage engine for a certain database, only for single tables, You can, however, specify a storage engine to be used during one session with:
SET storage_engine=InnoDB;
so you don't have to specify it for each table.
How do i confirm, if indeed all the tables are using InnoDB
All the tables were using myISAM.
I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes.
My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique:
SELECT OBJECT_NAME(OBJECT_ID) as tableName,
last_user_update as lastUpdate
FROM mydb.sys.dm_db_index_usage_stats
This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?

For example (iId is the input value)
DECLARE pVal INT(20);
DECLARE val INT(20);
SELECT price INTO pVal FROM products WHERE Id=iId;
SELECT price FROM products;
IF price == pVal THEN
SET val = price;
END IF;
