Oracle database all table names and schema name are in upper case but when you run the same file in Greenplum , all table names and schema names are in lower case. For example I have a parameter files that contains schema in and table name for HR schema from oracle oraclehr.txt HR EMPLOYEES HR DEPARTMENTS HR LOCATIONS In Greenplum we want it to be hr employees hr departments hr locations. to do this, you need to open the oraclehr.txt in vi and run :%s/.*/\L&/ Conversely, :%s/.*/\U&/ will change all the characters to uppercase. also Open the file in vi press Esc then for uppercase: gggUG for lowercase: ggguG |
