Tell me what’s wrong in these two queries?
SELECT * FROM `product_description` WHERE CHAR_LENGTH (description) > 250
SELECT * FROM `product_description` WHERE LENGTH (description) > 250
They return these error
Function table.name CHAR_LENGTH does not exist
Function table.name LENGTH does not exist
both functions seems not to work… what is going on ?
Maybe it is this which causes the issue
By default there must be no whitespace between a function name and the parenthesis following it. This helps the MySQL parser distinguish between function calls and references to tables or columns that happen to have the same name as a function. However, spaces around function arguments are permitted.
