 | o | EXTRACT(xml, xpath, [, namespaces ])           | Returns the XML fragment of the element or elements matched by the XPath expression. The optional namespace value that specifies a default mapping or namespace mapping for prefixes, which is used when evaluating the XPath expression
 | o | EXISTSNODE(xml, xpath, [, namespaces ])        | Determines whether traversal of a XML document using a specified xpath results in any nodes. Returns 0 if no nodes remain after applying the XPath traversal on the document fragment of the element or elements matched by the XPath expression. Returns 1 if any nodes remain. The optional namespace value that specifies a default mapping or namespace mapping for prefixes, which is used when evaluating the XPath expression.
 | m | EXTRACTVALUE(xml, xpathExpr))                  | Returns the text of the first text node which is a child of the element or elements matched by the XPath expression.
+| h s | FIND_IN_SET(string, stringArray)             | Returns the index (1-based) of the given *string* in the comma-delimited *stringArray*  Returns 0, if the given *string* was not found or if *string* contains a comma
 | b | FLOOR(value)                                   | Similar to standard `FLOOR(value)` except if *value* is an integer type, the return type is a double
 | b | FORMAT_DATE(string, date)                      | Formats *date* according to the specified format *string*
 | b | FORMAT_DATETIME(string, timestamp)             | Formats *timestamp* according to the specified format *string*
 | h s | FORMAT_NUMBER(value, decimalVal)             | Formats the number *value* like '#,###,###.##', rounded to decimal places *decimalVal*. If *decimalVal* is 0, the result has no decimal point or fractional part
 | h s | FORMAT_NUMBER(value, format)                 | Formats the number *value* to MySQL's FORMAT *format*, like '#,###,###.##0.00'
 | b | FORMAT_TIME(string, time)                      | Formats *time* according to the specified format *string*
 | b | FORMAT_TIMESTAMP(string timestamp)             | Formats *timestamp* according to the specified format *string*
-| h s | FIND_IN_SET(string, stringArray)             | Returns the index (1-based) of the given *string* in the comma-delimited *stringArray*  Returns 0, if the given *string* was not found or if *string* contains a comma
 | s | GETBIT(value, position)                        | Equivalent to `BIT_GET(value, position)`
 | b o | GREATEST(expr [, expr ]*)                    | Returns the greatest of the expressions
 | b h s | IF(condition, value1, value2)              | Returns *value1* if *condition* is TRUE, *value2* otherwise
