Comparing two tables in SSIS

Hi,

I am actually trying to achieve the following criteria hope someone could help me out.

I have two table as follows

I Want to compare Table 1 and Table 2. The relation between two tables is Record key. In Table 2 i want to compare date of codes which is "WC" and "OK" which has to be same dates if yes then update Table 1 column code as "TRUE" o/w "FALSE".

I am trying this one in SSIS and Table 1 and Table 2 are quite large tables. I know lookup make slow your process.So i am which way can i achieve this process.

Any ideas would be helpful.

Thanks in advance.
