Provenance

CMS sent the claims files as comma separated value files (.csv) along with a SAS load script and a data dictionary. It was found that the data dictionary files were incorrect and could not be used to load the data into SQL. Instead, the process below was used.

For the code used for these processes, email datacore@osumc.edu.

  • The .csvfiles were loaded into SAS using the provided SAS load files.
  • SQL tables were created using the proc sql "create table like" command in SAS. 
  • SAS was then used to convert the .csv into Tab Separated Value files (.tsv)
  • A bulk copy program (BCP) was used in order to upload the .tsv into SQL. 
  • The provided data dictionary was used to generate metadata about the dataset fields and was used to generate the data dictionary.
