QUERY_SQL=select {COLUMN_NAME} from {from_schema_table} where region = ${REGION} and STOP_TIME>trunc(add_months(sysdate,-3),''MM'')#;
DELETE_SQL=delete from {TO_SCHEMA_TABLE} where region = ${REGION}#;#
INSERT_SQL=insert into {TO_SCHEMA_TABLE} ({COLUMN_NAME},oprtime) values (?,?,?,?,?,?,?,?,?,?,sysdate)#;#

q'[QUERY_SQL=select {COLUMN_NAME} from {from_schema_table} where region = ${REGION} and STOP_TIME>trunc(add_months(sysdate,-3),''MM'')#;];||chr(10)||
q'[DELETE_SQL=delete from {TO_SCHEMA_TABLE} where region = ${REGION}#;#]'||chr(10)||
q'[INSERT_SQL=insert into {TO_SCHEMA_TABLE} ({COLUMN_NAME},oprtime) values (?,?,?,?,?,?,?,?,?,?,sysdate)#;#]')
