You need to very smart and aware while writing code for this

algo will be like this
1. Get the address string
2. slipt the string by whitespace
3. create a query
4. pass the slipted string members to where clause of your query .

I believe your query contains AND condition in the where clause. the state 'TEMPA' is not provided by the user hence it will fail. i will suggest you to create dynamic query string depending upon what user had provided.

Solution 4

you can make use of like operator

SQL

SELECT col1,col2,col3 FROM Addresstable WHERE State LIKE '%' + @state + '%' and
City LIKE '%' + @city + '%'

Here

SQL

@state

and

@city

are parameters being passed.
