ill-defined question, but I think I can answer

by john.a.wills In reply to What does it mean when a ...

What does WHAT mean when etc.? The question would have made more sense with "that" where you have "when". With that correction I cannot answer your question due to lack of context, but I imagine that what is really at issue here is strings of characters constituting so-called "regular expressions", used for searching texts and lists. The "$" refers to the end of a line in a text, so that, for example, if you search in an editor (say vi) for "xyz$" you will find the next instance of "xyz" at the end of a line.

The "%" is a bit trickier, because it is not, so far as I am aware, defined in regular expressions properly so called. However, it is recognized by SQL in a text as being anything in the context you give, e.g., if you input the clause WHERE t. xyz = '%aha' you will restrict yourself to values of xyz ending in "aha"; "%" can also be placed part-way along a string or at the end of the string (probably its most frequent position).

If this doesn't solve you problem, please give better context.

What does WHAT mean when etc.? The question would have made more sense with that 2 where you have when. With that correction I cannot answer your question due to lack of context, but I imagine that what is really at issue here is strings of characters constituting so-called regular expressions, used for searching texts and lists. The $ refers to the end of a line in a text, so that, for example, if you search in an editor (say vi) for xyz$ you will find the next instance of xyz at the end of a line.

The % is a bit trickier, because it is not, so far as I am aware, defined in regular expressions properly so called. However, it is recognized by SQL in a text as being anything in the context you give, e.g., if you Use %aha in a WHERE clause %aha you will restrict yourself to values of the specified column ending in aha; % can also be placed part-way along a string or at the end of the string (probably its most frequent position).

If this does not solve you problem, please give better context.

If this text is not as clear as it should be, that is because TR is being a nuisance about quotation marks and apostrophes.
