Detailed Description

This macros determines number of partitions and assigns each patID to a partition.

Determine the number of partitions needed for the dataset based on filesize. Create one partition for every 2G of data.
If there is more than one partition required, then create a partition-id for each patid. Only keep the necessary split_vars for the partition.

Program inputs

&DATALIB..&DATAFILE. (Dataset to determine number of partitions.)

Program outputs

&OUTFILE. (Dataset containing each partition number.)

Usage

%ms_partition_patients(DATALIB=worktemp, 
                       DATAFILE=meds, 
                       SPLIT_VARS=patid,
                       OUTFILE=medspartition);

Parameters

[in]	DATALIB	Library for input dataset.
[in]	DATAFILE	Source data to be split.
[in]	SPLIT_VARS	Variables needed to identify unique records.
[out]	OUTFILE	File containing patient partitions.

SAS Macros Dependencies

None.
