Query Responds With Check the 'Function Name Parsing and Resolution' section in the Reference Manual

Question

Would someone please explain to me what is wrong with this??

SELECT COUNT (`ID`) FROM `tableImSpecifying` WHERE `VisitorsEmail` = \'$VarThatHoldsEmailFromA$_         


        

Answer 1

Change:

SELECT COUNT (`ID`) 

to

SELECT COUNT(`ID`) 

The space is messing it up.

Answer 2

MYSQL doesn't like white space after function names. Try taking out the space after COUNT.

I also take it that those variable names are just an example and your not actually using them in production!

Answer 3

I also encountered the same problem while running the query

SELECT MIN (released_year) FROM books

where i encountered the error

FUNCTION records.MIN does not exist.
Check the 'Function Name Parsing and Resolution' section in the Reference Manual.  

But it worked when i removed the space between MIN and (released_year) so the correct one is:

SELECT MIN(released_year) FROM books

Answer 4

This:

FUNCTION myhost_classifieds.COUNT does not exist. Check the 'Function Name Parsing and Resolution' section in the Reference Manual

Would prompt you to read this

Which leads you to alter this:

COUNT (`ID`)

To:

COUNT(`ID`)

(note the removed space).

(you could also fiddle around with IGNORE_SPACE, but I wouldn't recommend it for a novice.

Answer 5

try this

 SELECT COUNT(`ID`) FROM `tableImSpecifying` WHERE `VisitorsEmail` = '$VarThatHoldsEmailFromA$_POSTInput'
            ^^-------remove space here

Answer 6

In simple terms, according to Wrikken, on the SQL Manual it says,

To use the name as a function call in an expression, there must be no whitespace between the name and the following ( parenthesis character.

So the expression,

SELECT COUNT (`ID`) FROM `tableImSpecifying` WHERE `VisitorsEmail` = '$VarThatHoldsEmailFromA$_POSTInput'

doesn't work because there is a whitespace between COUNT and the ( ). Simply remove the whitespace and change it to:

SELECT COUNT('ID') ...
