| Merging SAS Data Sets |
| Preparing Data for
Match-Merging |
| To prepare for match-merging, you first
reference all SAS libraries where input
data sets are stored, or where you will store the results of the match-merge.
Then you determine whether your input data sets are in the appropriate form
to be merged.
In DATA step match-merging, all data sets to be merged must be sorted or indexed by the values of a common variable (also known as a BY variable). The common variable must have the same type and length in all data sets to be merged. |
