Problem Note 66466: Incorrect data might be inserted into a PostgreSQL table when you use the BULKLOAD option
 |  |  |  |  |
A SAS data set that contains character data with one or more backslash (\) characters and 8-bit characters might be inserted incorrectly into a PostgreSQL table when you use bulk-load functionality. This issue happens when you run SAS with single-byte encoding such as Latin1.
For example, when you run the following code, a character variable that contains ÅBCDE\F\G is incorrectly inserted into the PostgreSQL table as ÅBCDEFFGG:
data test_bulkload;
length str $256 ;
str='ÅBCDE\F\G';
run;
length str $256 ;
str='ÅBCDE\F\G';
run;
libname pglib postgres server="mypg.server.com" user=myuser password=mypasswd database=db port=5432;
proc append force
base=PGLIB.test_bulkload (BULKLOAD=YES BL_DELIMITER=',' BL_ESCAPE=ON BL_PSQL_PATH='/sashome/SASWebInfrastructurePlatformDataServer/9.4/bin/psql')
data=test_bulkload;
run;
base=PGLIB.test_bulkload (BULKLOAD=YES BL_DELIMITER=',' BL_ESCAPE=ON BL_PSQL_PATH='/sashome/SASWebInfrastructurePlatformDataServer/9.4/bin/psql')
data=test_bulkload;
run;
You can circumvent the problem by running SAS with UTF-8 encoding or setting BULKLOAD=NO.
