update table in oracle using oledb command

i have a table dbo.tablesql in sql server and i am only interested in one column, lets say the column name is metername

i have a table tableoracle in oracle and i would have to do an update on that table using oledb command in ssis.

i.e.

update tableoracle set metervalue = 'xyzabc' where metername in (?);

all the values in dbo.tablesql should be that ?

lets say we have 10 values in dbo.tablesql
a, b, c, d......

so my update command should be

update tableoracle set metervalue = 'xyzabc' where metername in (a,b,c,d.....);

how do i make this work

thanks again

Thanks
