How to use the Postgresql pl/sql WHILE LOOP, with the keywords EXIT and CONTINUE.

PostgreSQL - WHILE LOOP https://github.com/softwareNuggets/PostgreSQL_While_Loop A WHILE loop in PostgreSQL is a control structure that allows you to execute a block of code repeatedly as long as a specific condition is met. It is useful for performing an operation repeatedly until a certain condition is satisfied, such as iterating over a table until all rows have been processed. For example, you could use a WHILE loop to iterate over a table of data and insert each row into another table until all rows have been processed. The while loop statement runs code until the expression evaluates to false. PostgreSQL evaluates the expression before executing the block of statements in this syntax. If the condition is met, the statements are carried out. The while loop evaluates the condition again after each iteration. How to use Raise Notice?

This could be a specific number of iterations, a certain value being reached, or a specific condition being met. Use the WHILE keyword followed by the condition to start the loop. Write the code that you want to execute repeatedly inside the loop. This could be a set of SQL statements, a function call, or any other code that you want to execute multiple times. Use the LOOP keyword to indicate the end of the code block that will be executed repeatedly. Use the END keyword to indicate the end of the loop. Test your code to make sure that the loop is executing correctly and stopping when the specified condition is met. Use the EXIT keyword to exit the loop early if a specific condition is met. Use the CONTINUE keyword to skip the rest of the current iteration and move on to the next iteration of the loop. Use the BREAK keyword to break out of the loop entirely. Use the ITERATE keyword to go back to the beginning of the loop and start the next iteration. #softwarenuggets, WHILE LOOP, @softwareNuggets
