How to display encoded values in SQL?
I have some data that is encoded in my select query. Unfortunately it doesn’t show the data. It just returns 7 columns and each column has each value. I only want 1 column with the different values. Please provide different solutions to display the data. You can use VALUES, aka Table Value Constructor, clause for encoded values:
Table of Contents

How to insert encoded values in SELECT query?
SELECT syntax. See reference for more details. The encoded values should be in your SELECT query rather than within VALUES. For example, you have a database like Movies (Title, Director, Cost, Profits). if you want to input the values into the respective tables, please select the table first and then insert the values into those tables.

How to get rid of unwanted characters in SQL?
If you want to detect hidden or unwanted characters as part of an initial diagnosis, use LENGTH. Then use TRIM to get rid of unwanted characters. We also discuss how you can nest SQL functions, which is a powerful technique in programming.
Why do you need to avoid hard coding in your SQL code?
No more no less. It’s risky and a bad idea (it’s also doubly risky with character sets that store a variable number of bytes for characters outside the ASCII character set). I can’t estimate how many bytes the variable will need in the future, so it’s better to use more than 100 bytes in that case.
Is the second query hard coded or does it bind correctly?
The first query joins correctly (according to available data), but the second query is hard coded to get the value (and by the way gives the cartesian product, the columns don’t join correctly here and you can get duplicate values). Check if the index has been created on relevant fields.
