从db2到oracle的转换

Question

SELECT MESSAGE_ID, SHORTDESC 
FROM VERNACULAR_MASTER 
WHERE position(chr(10), SHORTDESC, CODEUNITS16)>0 
or  position(chr(13),SHORTDESC, CODEUNITS16)>0 

以上查询采用db2格式。如何将其转换为oracle格式？

Answer 1

的DB2的POSITION(search_string, source_string, encoding)功能是Oracle的INSTR(string, sub_string)功能：

SELECT MESSAGE_ID, SHORTDESC 
FROM VERNACULAR_MASTER 
WHERE INSTR(SHORTDESC, CHR(10))>0 
OR  INSTR(SHORTDESC, CHR(13))>0
