Informatica数据类型转换

Question

wanted to have two columns separate in target table

• Column: CTDATE in YYYYMMDD Format
• Column: CTTIME in HHMMSS Format.

How can I populate in Expression Transformation? What is the expression used? Please guys, help me out.

I used

• TO_CHAR(in_column, 'YYYYMMDD') for CTDATE
• TO_CHAR(in_column, 'HHMISS') for CTTIME

Answer 1

If your in_column type is already date/time then what you are using right now is almost correct, except use HH24MISS instead of HHMISS . Or use HH12MISS AM .

• TO_CHAR(in_column, 'YYYYMMDD') for CTDATE
• TO_CHAR(in_column, 'HH24MISS') for CTTIME

If in_column is a string , the first convert it to a date/time . Suppose in_column is coming as 'Jan 24 2017 14:24:56' then

• first create a variable v_in_column as TO_DATE( in_column, 'MON DD YYYY HH24:MI:SS' )
• Then use this variable to derive CTDATE and CTTIME
  • TO_CHAR(v_in_column, 'YYYYMMDD') for CTDATE
  • TO_CHAR(v_in_column, 'HHMISS') for CTTIME
