Sas data merge7/7/2023 So the dataset ends up with only two records. ** Notice that at iteration 4, it's comparing records 4 to 4, not 3 to 4, as we humans would do. Here's what I think SAS does conceptually with your program and my attempt: Apparently, when you're merging by ID only, SAS ignores all other fields and merges one by one in sequence. reads the descriptor information of each data set named in the SET statement and then creates a program. Jymm, your solution seems to have the same problem as my first attempt. Sas merge datasets with same variable names. The bad news is that I tried jymm's solution and- no dice. SAS has been described as an icon of NorwegianSwedishDanish cooperation. The good news is that I tried teralearner's solution and it worked beautifully. In 1951, all the airlines were merged to create SAS. One attempt didn’t work- I tried to sort HOSP by “ID” and “start” and EVENT by “ID” and “date”, then merge by ID only (since the dates won’t necessarily be an exact match).Īny thoughts? Thanks! RE: Merge by date range, not exact date teralearner (TechnicalUser) 29 Apr 03 22:05 The optional arguments are the data set options. You can keep adding more arguments to join more tables. Common Errors with MergeAttributes (label, format, and informat) are different between data sets in variableswith the same nameIn a merge, SAS uses. So I want my output to have 5 records, merging (A) in HOSP with each (A) in EVENT, (B) with (B) and (C) with (C). MERGE SAS-data-set-1 < ( data-set-options )> SAS-data-set-2 < ( data-set-options) > < SAS-data-set-n < ( data-set-options )> The MERGE statement contains at least two obligatory arguments, namely the SAS tables you want to join.data barf create the dataset BARF infile s:mysasTable7.1 open the data file TABLE7.1. In this article, we will discuss both methods, provide examples, and discuss their advantages and disadvantages. SAS Programming:File Merging and Manipulation. Namely, you can either use the LEFT JOIN operation from the PROC SQL procedure or the MERGE statement in a SAS data step. How can I merge these two so that I get a match whenever a procedure was done during a matching hospitalization? The problem is that the data in EVENT may not exactly match any field in HOSP. In SAS, there are two ways to left join tables. I have one dataset (HOSP) with hospitalization data and another (EVENT) with procedure data.
