| DecimalToDecimal(mylink.mydec,”ceil”) | If the column mylink.mydec contains the decimal number 2.5345, the following function returns the decimal number 00000002.54 |
| DecimalToString(mylink.mydec,”suppress_zero”) | If the column mylink.mydec contains the decimal number 00000004.00, the following function returns the string “0000000000000000000000000004.0000000000”. |
| DecimalToString(mylink.mydec,”fix_zero”) | If the column mylink.mydec contains the decimal number 00012344.00, the following function returns the string “12344”. |
| StringToDecimal(mylink.mystring,”ceil”) | If the column mylink.mystring contains the string “19982.2276”, and the target is defined as having a precision of 7 and a scale of 2, then the following function returns the decimal 19983.23. |
| DecimalToTimestamp(mylink.mytimestampdec, “%hh%nn%ss%yy%mm%dd”) | If the column mylink.mytimestampdec contains the decimal value 200658580818, then the following function returns the timestamp 1958–08–18 20:06:58: |
| IsValid(“int8”,mylink.mystring) | If the column mylink.mystring contains the string “1”, then the following function returns the value 1 If the column mylink.mystring contains the string “380096.06”, then the following function returns the value 0. |
| IsValidDate(mylink.mydate) | If the column mylink.mydate contains the date 2011-09-13, then the following function returns the value 1. If the column mylink.mydate contains the string “380096.06”, then the following function returns the value 0, because the converted string is not a valid date. |
| IsValidDecimal(mylink.mynum) | If the column mylink.mynum contains the value 310007.65, then the following function returns the value 1. If the column mylink.mynum contains the string “wake-robin”, then the following function returns the value 0, because the converted string is not a valid decimal. |
| IsValidTime(mylink.mytime) | If the column mylink.mytime contains the time 23:09:22, then the following function returns the value 1: If the column mylink.mydate contains the string “IbnKayeed”, then the following function returns the value 0, because the converted string is not a valid time. |
| IsValidTimestamp(mylink.mytimestamp) | If the column mylink.mytimestamp contains the time 2011-09-13 23:09:22, then the following function returns the value 1: If the column mylink.mytimestamp contains the string “one of two”, then the following function returns the value 0, because the converted string is not a valid timestamp. |
| StringToTime(mylink.mystring,”%(h,s):$(n,s):$(s,s)”) |
