Regarding Message Mapping in JDBC Scenario

Question

Hello Experts,
        I got struct up in message mapping. In message mapping we can able to see different types of Functions. So I need some clarifications on it. Functions are available like...
Conversions
Boolean
Node Functions
Constants
Date
Text
Static
Arithmetic
So please explain in simple for each functions.
Points will be rewarded.
Thank you

Hi
*Boolean*:-
And -- checks for 2condition, return a true value if both condition are satisfied
Or --checks for 2condition, return a true value if one condition is true.
Not - checks if the condition is not equal to.
Equals - Check whether 2 Boolean values are equal
NotEquals
If u2013 Returns second value if the first argument is true. otherwise returns third argument
If WithoutElse u2013 Returns value of second argument, if first argument is true.
Node Functions:-
createIf - Produces empty value if argument is true; Resultlist.SUPPRESS otherwise
removeContexts u2013 Produces plain stream of values with No context changes
replaceValue u2013 replaces value of source field to value specified in Function Properties.
Exists u2013 Returns true, if Node exists otherwise false
SplitByValue u2013 inserts context changes after event specified
collapseContexts u2013 Produces one empty string value out of each arguments context. All arguments are in one context
useOneAsMany u2013 Use First Argument as IS on same level as third argument. second argument defines when next value of first argument is used
sort u2013 sorts values in each context
sortByKey u2013 Sorts values in second queue by keys from first queue
mapwithDefault u2013 Inserts default values specified in the function properties into empty contexts
formatByExample u2013 Takes values from the first queue and inserts them in the structure of second queue.
Constants:-
Constant u2013 Generates constant value
CopyValue u2013 Takes specified value in argument stream and copies it an infinite number of times
Sender u2013 Sender System
Receiver u2013 Receiver System
Date:-
CurrentDate u2013 Return current date in specified format
DateTrans u2013 Transforms date from input format to output format
Dateafter u2013 Returns True if first date is after second otherwise false
DAteBefore - Returns True if first date is before second otherwise false
CompareDates u2013 Compares two dates
Text:-
Substring u2013 Returns substring depending upon the given parameters
Concat u2013 concatenates 2 strings inserting delimiter string parameter between them
Equals u2013 Check whether Strings are equal
indexOf2 u2013 returns the index where the second string is found for the first time in the first string
indexOf3 u2013 As with indexOf with 2 parameters, But starting search at the specified position
lastindexOf2 u2013 Returns the index where the second string is found for the last time in the first string
lastIndexOf3 u2013 As with lastIndexOf with 2 parameters starting search at the specified position
compare u2013 compares 2 strings lexicographically
replaceString u2013 Replaces each occurrence of pattern(2nd argument ) of source string(1st arg). By third string
length u2013 returns length of string
endsWith u2013 Tests whether string ends with specified suffix
startsWith2 u2013 Tests whether string starts with specified prefix
startsWith3 u2013 Tests whether string starts with specified prefix beginning at specified location
toUpperCase u2013 Converts all characters in string to upper case
trim u2013 Removes white space from both ends of string
toLowerCase u2013 Converts all characters in String to Lower case
Statistic:-
sum u2013 calculates sum of all numbers in each context
average u2013 calculates the average of all numbers in each context
count u2013 Counts number of values in each context
Index u2013 For each incoming value, this Function returns the index number of the incoming value in the context, String from the initial index and increasing by the increment defined in the parameters.
Arithmetic:-
Add u2013 add two values
Subtract u2013 subtracts second value from the first value
equalsA u2013 Returns true; If float numbers represented by argument strings are equal otherwise returns false
abs u2013 returns Absolute value of argument
sqrt u2013 Returns square root of the number
sqr u2013 Returns square of the number
sign u2013 Returns -1 if number is negative, +1 if positive, 0 if 0
neg u2013 Multiplies number to -1
1/x u2013 calculates 1/x
Power u2013 Returns value of the first argument to the power of the second argument
Less u2013 Returns true if the first number is less than the second number otherwise false
Greater - Returns true if the first number is greater than the second number otherwise false
Multiply u2013 Multiplies 2 values
Divide u2013 Divides first value by the second value
Max u2013 Returns maximum of 2 numbers
Min u2013 Returns Minimum of the 2 numbers
Ceil u2013 Returns the smallest (closest to the negative infinity) initial value that is not less than the argument and it is equal to the mathematical integer.
Floor - Returns the largest (closest to the negative infinity) initial value that is not Greater than the argument and it is equal to the mathematical integer.
Round u2013 Returns closest initial value to the argument
Counter u2013 Counts number of invocations. Initial value and increment defined by Parameters.
FormatNum u2013 Formats Number with given pattern.
Conversions:-
FixValues u2013 Creates a Local Table to perform a value Mapping
ValueMapping u2013 Define jump to Value Mapping table of Integration Directory.
