SELECT SUBSTR( OP_SOURCE ,1 ,4 ) SOURCE
     , ONLINE_FLAG, 'TRD' AS SRC_SYS
     , CURRENT_TIMESTAMP AS ETL_LOAD_TIME
  FROM tb_keyword_source;

Netezza Syntax

Syntax After Migration

INSERT INTO tmp_tb_keyword_freeze
     ( BRANCH_CODE, FREEZE, UNFREEZE, BRAN_JYSDM )
SELECT BRANCH_CODE, FREEZE, UNFREEZE, BRAN_JYSDM
  FROM tb_keyword_freeze;
INSERT INTO tmp_tb_keyword_freeze
     ( BRANCH_CODE, "FREEZE", UNFREEZE, BRAN_JYSDM )
SELECT BRANCH_CODE, "FREEZE", UNFREEZE, BRAN_JYSDM
  FROM tb_keyword_freeze;

Note

A new configuration parameter "keywords_addressed_using_doublequote" should be introduced with the below value:

keywords_addressed_using_doublequote=freeze

keywords_addressed_using_as=owner,attribute,source,freeze

create table t12 (c1 int, FREEZE varchar(10)); ==> create table t12 (c1 int, "freeze" varchar(10));

select c1, Freeze from t12; ==> select c1, "freeze" from t12;

select c1 freeze from t12; ==> select c1 as freeze from t12;
