Controlling The Flow – Part 4

admin

I am going to continue my articles (tidbits) on controlling the execution flow of statements in a Transaction SQL (T-SQL) program. Every program has to be deterministic on what step to execute next. Otherwise, the computer would be clueless on what to do next. The only exception to this rule is error handling. A runtime error may cause the program to branch to a error handler and exit the program. Today, I want to talk about how to use the GOTO statement. I never use this statement during my coding…

I am going to write a few articles (tidbits) on controlling the execution flow of statements in a Transaction SQL (T-SQL) program. Every program has to be deterministic on what step to execute next. Otherwise, the computer would be clueless on what to do next. The only exception to this rule is error handling. A runtime error may cause the program to branch to a error handler and exit the program. Today, I want to talk about looping for repetition, statement blocks, and conditional execution. Some programming languages support the…
