Convertion functions in BODS with Examples_Part1

Conversion functions in BODS_Part1

There is different conversion function which used to convert one form of data into another format. The BODS support most of basic conversion functions.

Here, I will explain the syntax and examples for those conversion functions.

1. To_char

The to_char function used to convert number or date value into string format.

This function will help you to convert a number or date to string.

The syntax for this function is given below with examples.

To_char(number or date, format)

Number to string.

e.g.      

• to_char(123,’9999’)= ’123’

• to_char(123,’09999’)=  ‘0123’
• to_char(31,’xx’) = ‘1f ‘ ----> string contains hexadecimal integer.
• to_char(31,’xx’)= ’37’ ----> string contains octal integer

Date to string.

e.g.

• to_char(sysdate(),’MM’)= ‘06’ --> month number of the date
• to_char(sysdate(),’MON’)= ‘JUN’  ---> Month name with 3 letter like ‘JUN’
• to_char(sysdate(),’MONTH’)= = ‘JUNE ‘ ----> Month name  like 'JUNE'.
• to_char(sysdate(),’DD’)=’03’ ----> Day part of the date
• to_char(sysdate(),’YY’)=’13’-----> 2 digit YEAR
• to_char(sysdate(),’YYYY’)=’2013’----> 4 digit YEAR
• to_char(sysdate(),’HH’)=’12’----> 2 digit Hour
• to_char(sysdate(),’MI’)=’13’----> 2 digit Minute
• to_char(sysdate(),’SS’)=’13’----> 2 digit Second
• to_char(sysdate(),’FF’)=’286959000’----> Sub second

2. Intervel_to_char

This function is to convert an interval to string. This will help you find out the date difference between two dates in different format. Find below given examples and syntax for this function.

The syntax for this function is given below.

Interval_to_char(interval, interval type)

$start_date=2013.01.01 00:00:00

sysdate() = 2013.06.05 17:31:54

Interval_to_char($start_date- sysdate(),’D’)=’155’

This statement will give the number of days between given interval. Similarly,

Interval type:     M for minutes

                          S for Seconds

                          H for hours

3. Julian_To_Date

This will convert Julian value to date value.

The syntax for this function is given below.

Julian_to_date(Julian) return date

Julian_to_date(2,451,545) = 2000.01.01 00:00:00

Please refer below link to get more information about Julian day.

4. Num_to_Intervel

This function will help you to convert an number into interval value.

The syntax and examples are given below.

If sysdate()=2013.06.05 17:52:21

E.g. sysdate()+num_to_intervel(12,’D’)=2013.06.17 17:52:21(Adding 12 days to given date)

       sysdate()+num_to_intervel(1,’H’)=2013.06.05 18:52:21(Adding 1 hour to given date)

Similarly, the number can convert into minutes (M) and seconds(S).
