Hi,

I have 2 data sets (DataSet1 , DataSet2):

- The Data Set "DataSet1" has 2 variables (1_A , 1_B) with 3 observations

1_A | 1_B |

2 | 2 |

3 | 1 |

5 | 19 |

- The Data Set "DataSet2" has 3 variables (2_A , 2_B , 2_C) with 2 observations

2_A | 2_B | 2_C |

2 | -5 | 9 |

21 | 13 | 8 |

I want to join these 2 Data Sets, and SAVE as a new Data Set named "DataSet3" as show below:

1_A | 1_B | 2_A | 2_B | 2_C |

2 | 2 | 2 | -5 | 9 |

3 | 1 | 21 | 13 | 8 |

5 | 19 | . | . | . |

How shoud I proceed?

Thanks!

One-to-One merging from SAS documentation

One-to-one merging combines observations from two or more SAS data sets into a single observation in a new data set. To perform a one-to-one merge, use the MERGE statement without a BY statement. SAS combines the first observation from all data sets that are named in the MERGE statement into the first observation in the new data set, the second observation from all data sets into the second observation in the new data set, and so on. In a one-to-one merge, the number of observations in the new data set is equal to the number of observations in the largest data set named in the MERGE statement. See Example 1 for an example of a one-to-one merge. For more information, see Reading, Combining, and Modifying SAS Data Sets in SAS Language Reference: Concepts.

Syntax
