This is very useful. Can you please also show how this can be used to validate user input like for example:
We have this query currently: select id from users where id like '<user_enterred-value>%'; Now I want to validate that the user-enterred-value is only a numeric value... (the major problem is where users enter special characters that leads to exceptions / errors being thrown - like if the user enterred ' (a single quote) that would close the string and the %' would be considered as an invalid character..)
