Tutorial by Topics: limit



As database tables grow, it's often useful to limit the results of queries to a fixed number or percentage. This can be achieved using SQL Server's TOP keyword or OFFSET FETCH clause.

DEX means Android app's (APK) executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app.

The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536 (64K)—including Android framework methods, library methods, and methods in your own code.

To overcome this limit requires configure your app build process to generate more than one DEX file, known as a Multidex.

Some times you may need to create a delimited text file for various uses. The following example is one of many ways to help you do that. I have used a pipe ("|") for my delimiter, to change that just change the assignment of the Sep variable. In my example I dump the recordset to an array, this is by no means the defacto approach, its just my go to. This can easily be done using the recordset itself as well.

Batch files allows only 32bit integer calculations , though this can be bypassed with different approaches.
