In order to fully utilize the capabilities of MS Access, one must learn not only learn the Visual Basic (VB) programming language, but should also learn Standard Query Language (SQL). Once a grasp of these two languages have been obtained, MS Access users can begin to build faster and more efficient databases.
One tool that has proved itself very useful to me over the years is querying data from tables or queries using VB and SQL code. A brief introduction to this process is presented in this article. To best understand this process, an example is provided below along with an explanation of its parts.
Dim rstTemp As Recordset
Dim strSQL As String
Dim routeNum As Integer
strSQL = "SELECT [Route], [Main Route PM], [Intersecting Route], [IntBeginPM], [IntEndPM] â€œ
strSQL =Â strSQL + â€œFROM Intersections_list WHERE (((CStr([Route])) = """ + cmbRouteQuery + """));"
Set rstTemp = CurrentDb.OpenRecordset(strSQL, dbOpenDynaset)
If (Not (rstTemp.EOF)) Then
routeNum = rstTemp(0)
An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.
Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications. Enterprise grid computing creates large pools of industry-standard, modular storage and servers. With this architecture, each new system can be rapidly provisioned from the pool of components. There is no need for peak workloads, because capacity can be easily added or reallocated from the resource pools as needed.
How can write a SELECT statement that finds the n greatest values in a column? From what i’ve read, the TOP statement only returns the first n rows, it doesn’t take any regard to the values. For example, if a have a column with ages, i want to be able to find the 5 oldest people.

I wrote this little table and procedure to help me remember what style 104 did, or how to get HH:MM AM/PM out of a DATETIME column. Basically, it populates a table with the valid style numbers, then loops through those, and produces the result (and the syntax for producing that result) for each style, given the current date and time.
It uses also a cursor. This is designed to be a helper function, not something you would use as part of a production environment, so I don’t think the performance implications should be a big concern.
In an SQL Server View, a problem is that the DateTime field has many Null values which is causing a problem with the parsing of the data in MSAccess.
How to I use CAST (or CONVERT) to handle Null Date values in my SQL Server view?
There is a way to use CAST or CONVERT similar to the nz type function in MSAccess to handle null date values but I can’t remember the syntax.
What is happening now is that I get a data mismatch in my MSAccess function when it hits a Null Date value. Can I somehow use the ISNULL or ISDate function? I believe I need to somehow return “” instead of Null.
