Hello All,
I am using a SqlDataSource with a GridView on a ASP.NET 2005 page. I have a DropDownList (control parameter {0}) and a TextBox(control parameter {1}). The user picks the field they want to search in the DropDownList and then types in a search into the TextBox and it doesn't appear to like the use of LIKE in the SqlDataSource's FilterExpression property; i.e.
SqlDataSource1.FilterExpression = "{0} LIKE '{1}'"; produces a filter that searches on EXACT MATCHes only instead of STARTS WITH like the docs say. What would be ideal for my requirements is a CONTAINS search, really. I know I could use CharIndex -- at least in an explicit WHERE clause -- however, putting FilterExpression="CharIndex('{1}',{0})>0) raises a System.Data.EvaluateException: The expression contains undefined function call CharIndex() error.
Any hints? Thanks in advance.
Sincerely Yours,

You need to use wildcard characters if you don't want to find an exact match.
The % wildcard matches zero or more characters. If you change your code to
SqlDataSource1.FilterExpression = "{0} LIKE '{1}%'";
you will get records that start with the specified sequence rather than exactly matching it.

I have the need for a database that has a large number of fields and would be accessable via ASP.NET Web page.
The table would center around locations;
Fort Worth, Topeka, etc.
Each location has up to 28 Backup Batteries that require a semi-annual inspection;
This inspection includes Voltage, Conductance, Tempreture, and Voltage with the charger off.
A number of true/false quesiton are also associated to the inspection.
Would it be best to create four tables for the Backup Batteries, another for the locations and quesitons, and then create a relationship with the Locations table for everything else?
Or would it be smarter to just create one gigantic table that has upwards of 130 columns?
Thanks,
|

Off the top of my head, the following tables should be sufficient:
1. Table to store locations
2. Table to store types of inspection check e.g. Voltage, Temperature
3. Table to store inspection questions
4. Table to store location/battery combinations
5. Table to store location/inspection instance combinations
5. Table to store location/inspection instance/battery/inspection check result combinations
6. Table to store location/inspection instance/inspection question result combinations

Hi Paul, would I need to have a common Primary Key field for each one? and then would I also need to "join" them?
Thanks,
|
|
|
|

The primary keys for the tables would look like this:
1. LocationID
2. InspectionCheckItemID
3. InspectionQuestionID
4. LocationID | BatteryID
5. LocationID | InspectionID
6. LocationID | InspectionID | BatteryID | InspectionCheckItemID
7. LocationID | InspectionID | InspectionQuestionID
You should also consider setting up referential integrity between the primary and foreign keys in your tables to ensure the overall integrity of your data.

If you are planning on using an ActiveRecord design pattern then I suggest you use surrogate keys on your tables, as it tends to make the mapping more straightforward.

To add a new column to a table, run a DDL query like the following:
ALTER TABLE mytable
ADD mycolumn datatype [NULL|NOT NULL]

hi
you can write the trigger on Source table for insert..
and you will get the inserted value from table "insertiing"
eg; select emp_staffid from inserting
will return the emp_staffid ie: inserted
and you can insert that value in to detination table
regards
Joe

hi All
In my Company we are using SQL 2000, and we want to upgrade to SQL2005. we have an inhouse GIS web Application that uses ARc GIS servers. Am not experienced in GIS. i just Gooogled what was Arc GIS server. Now ArcGIS server needs to be upgraded to version 9.2. So my question is, can we still keep the version of SQL 2000, while the upgrade of 2005 is taking place on the same server. because we want to keep some other applications under SQL 2000 And still upgrade to ArcGIS 9.2.
i hope i explained it, i tried
Thanks

Create a backup of your database. Restore it under a different name and run the upgrade wizard against this new database.

Shouldn't be any problem. SQL 2005 is backwards-compatible, so all your stored procedure code should work OK.

I'm not sure what you mean? How do you want to access it?
The best way to find out would be to try it for yourself. I don't have access to an instance of SQL 2000 at the moment.

Is it possible to iterate through a table or a temporary, because i have to add a temporary column and insert different values for each row according to condition to return a comma separated value. I show a rough sketch what i want to do.
Select SAP.LoginName,var="--Some Very Long Query according to a criteria within the rows of a table like where Test.Folder_ID=CM.Folder_ID--"
From dbo.sysCommunicatorMessages CM
Inner Join dbo.sysAppLogins SAP On CM.MESSAGEFROM = SAP.LOGIN_ID
where "--Some Criteria--" and CM.Folder_ID<>-2
I have used functions to solve the problem but they are currently not acceptable.
Bye

You could use a CURSOR. Have a look at this article[^].
