sql server 2008 r2 - ssis swap some values in a data flow if they match a lookup table -

-

here's problem - midstream in data flow, have values in 1 column want swap other values based on lookup table.

for example, if had rowset this:

key   value 1     2     b 3     4     c 5     d 6     b ...   ...

if had lookup table in sql server db looked this:

value1    value2 c         y d         z

then want package swap values resulting data flow this:

key   value 1     2     b 3     4     y 5     z 6     b ...   ...

what components produce simplest solution?

you use lookup component , then:

  • set ignore failure
  • values not match return null lookup value

  • use derived column expression populate lookup succeeded

    isnull(value2) ? value : value2
