Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error: Cast from type ''''DBNull'''' to type ''''String'''' is not valid. I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL. Is there another way around this? Check if it is equal to DBNull.Value first and if it is, don't do the cast.Stanley Tan theSpoke Blog Where in the code does it need to go?

What's the difference between 'Build' and 'Publish'
Greetings....this subject might belong in one of the Visual Studio forums but it's so danged noob-sque.... I'm particularly confused by the 'Precompiled' term in the Publish operation. I'm interested in the path of least resistance between my VS project and my public IIS webserver. thx--steve...  Build means creating the assembly of the project ( .dll or .exe file) wich contains MSIL and a manifest file.

'IN' Clause or 'OR'
Hello, [1]: select * from TABLEA where COL1 IN('value1','value2''valu3'....) [2]:select * from TABLEA where COL1 = 'value1' OR COL1= 'value2' OR COL1='valu3'. TABLEA is a huge table and it has non-clustered index on COL1. Among the above 2 queries, which query will give me the better performance or fast response and WHY? What is the difference between 'IN' and 'OR' clauses as for as Sybase Optimization is concerned. Which is the better one to be used on huge tables. Thanks. Mac An IN list is treated ...

'or' or 'union'
Hello I was just wondering, in general what is better to use, an 'or' clause in a select or a 'union' to join two selects together. Do both statements create work tables? Many thanks Alex I think OR will be better than union. because suppose u have 3 tables and using OR u can join table a and table b and table c so each table will have only one read. but using union you will join table a and table b and in another query of union u will use table (a or b) and table c so ur one read is more in union .
