Rpad - rpad(string_column, len, pad_string)Returns the string 'string_column', right-padded to a length of 'len' characters with the string 'pad_string'. If length of the string 'string_column' is greater than 'len', then the first 'len' characters of 'string_column' is returnedrpad('DB',5,'a') = DBaaa

Soundex
soundex(string_column)
Returns a soundex string from 'string_column'. The soundex string is similar for
same sounding strings.
soundex('Hello') = H400
Space
space(numeric_column)
The argument value is returned as the number of space characters.space(6) = ' '
Strcmp - strcmp(string_column1, string_column2)Returns -1 if the 'string_column1' is smaller than the 'string_column2', 0 if the two strings are same, and 1 if the 'string_column1' is greater than the 'string_column2'.strcmp('abcd', 'abcde') =-1
Substr
substr(string_column, start_pos, string_len [Optional])
Returns the substring formed by cutting off the string argument passed according
to the needs.
substr('abcddb', 2,) = bcddb
Substring - substring(string_column, start_pos, string_len)Returns a substring from 'string_column'. The substring begins at position 'start_pos' with the character length of 'string_len'.substring('abcddb', 1, 4) = abcd
Substring Between
substring_between(string_column, sub_string, sub_string, start_pos [Optional])
Returns the characters between the two given substrings in the main string.substring_between('abcddb','b','d',1) = c
Substring Count
substring_count(string_column, sub_string)
Returns the count of substring occurred in the main string.substring_count('abcddb','cd') = 1
Substring Index
substring_index(string_column, delimiter, delimiter_count)
Returns the substring from string 'string_column' before count 'delimiter_count'
occurrences of the delimiter 'delimiter'.
substring_index('how.are.you', '.', 2) = how.are
Substring Position
substring_position(string_column, sub_string, start_pos [Optional])
Returns the position of substring in the main string.substring_position('abcddb','cd') = 3
Trim - trim(string_column)Returns the string with all spaces removed in prefix and suffix of the string.trim(' abcd ') = abcd
Ucase
ucase(string_column)
Returns the string 'string_column' with all characters changed to uppercase.ucase('abcD') = ABCD
Unhex
unhex(string_column)
Returns the corresponding character for each pair of hexadecimal digits.unhex('21') = !
Upper
upper(string_column)
Returns the string 'string_column' with all characters changed to uppercase.upper('abcD') = ABCD
Uppercase - uppercase(string_column) &nbsp;Returns the string 'string_column' with all characters changed to uppercase.uppercase('abcD') = ABCD

#### Logical Functions

FUNCTIONDESCRIPTIONEXAMPLE
IF - if(expr1,expr2,expr3)Returns expr2 if expr1 is true else it returns expr3if(5> 10,100,3) = 3
If Case
if_case(column, matchExpr1, returnValue1, matchExpr2, returnValue2, ..., elseValue [Optional])
Returns the 'returnValue' if the given column satisfied with 'matchExpr'.if_case('Subject','issue','Issue List',equals('bug'),'Bug List','Support List') = if the 'Subject' column equals issue then it returns 'Issue List' else if 'Subject' column equals 'bug' then it returns 'Bug List' else it returns 'Support List' if_case('Subject',startswith('issue','bug'),'Issue List',contains('help','Call'),'Call List','Support List') = if the 'Subject' column starts with 'issue' or 'bug' then it returns 'Issue List' else if 'Subject' column contains 'help' or 'Call' then it returns 'Call List' else it returns 'Support List'
Ifnull - ifnull(expr1,expr2)Returns expr1 if expr1 is not null, else it return expr2ifnull(null,10) = 10
Is Empty
isempty(column)
Returns '1' if the given column does not have any value. Returns '0' if the given
column have some value.
isempty(null) = 1
isnull( ) - isnull(expr1)Returns 1 if expr1 is null, else it returns 0.isnull(null)- 1

#### General Functions
