![]() (Keep track of which input data set contributes to an To merge two or more data sets in SAS, you must first sort both data sets by a shared variable upon which the merging will be based, and then use the MERGE statement in your DATA statement. It doesn't matter which input data set is unmatched. One to one merge without matching variable: Ex: Data one Input stno age Cards 100 45 101 56 103 45 Data two Input gender $ weight Cards Female 56 male 58 female 45 Data three Input color $ Cards White Black White Data demo Merge. SAS can only use one set of values and will arbitrarily choose the values from the last dataset. There is one common variable among these two datasets by name Account. 3 DATA STEP MERGE SAS Merge allows the programmer to combine data from multiple datasets. To resolve the issue, you need to ask your SAS admin to click the check box "Allow XCMD" within SAS Management Console -> Server Manager -> SAS App - Workspace Server -> properties -> Options ->Advanced Options -> Launch Properties tab. The following program creates the RESEARCH data set for the sixth department, Research. Merging a dataset creates a new variable called merge that takes on a value for each case depending on the results of the merge: Table 1: merge values merge De nition The vertical merge is based on the rbind function in which the two data frames have the same variables but different cases (rows), so the rows build vertically, stacked on top of each other. variable for each variable listed in the BY statement. For example, you could use DSNames = T(datasets("work")) instead of hard-coding the data set names in this example. PROC APPEND places the observations from one data set to the end of another data set. MERGE Data-Set 1 Data-Set 2 BY Common Variable.
