DECLARE
CURSOR C
IS
SELECT cc_cd
FROM TEMP1 WHERE s_flg ='A' AND b_num IN('826114');--,'709537','715484');
CURSOR D
IS
SELECT * FROM cONSTRAINTS_test ORDER BY SRL_NUM;
STMT VARCHAR2(4000);
p_target_schema VARCHAR2(30):='schema1';
p_source_schema VARCHAR2(30):='schema2';
BEGIN
FOR REC IN C
LOOP
FOR REC1 IN D
LOOP
STMT := 'INSERT INTO '||p_target_schema||''||'.'||''||REC1.CHILD_TABLE||' SELECT * FROM '||p_source_schema||''||'.'||''||REC1.CHILD_TABLE||' where '||REC1.COLUMN_NAME||'='||REC.cntrct_cd||'';
Dbms_Output.Put_Line('THE VALUE STMT:'||STMT);
END LOOP;
END LOOP;
END;
cc_cd='434se22442ss3433';
cc_t_ms is parent table-----------------------pk_cc_cd is primary key
cc_cd is column name
CONSTRAINTS_test table
CHILD_TABLE NOT NULL VARCHAR2(30)
CONSTRAINT_NAME NOT NULL VARCHAR2(30)
COLUMN_NAME NOT NULL VARCHAR2(400)
R_CONSTRAINT_NAME VARCHAR2(30)
CONSTRAINT_TYPE VARCHAR2(1)
PARENT_TABLE NOT NULL VARCHAR2(30)
SRL_NUM NUMBER(4)
CHILD_TABLE     CONSTRAINT_NAME     COLUMN_NAME     R_CONSTRAINT_NAME     CONSTRAINT_TYPE     PARENT_TABLE     SRL_NUM
a aaa cc_CD     pk_cc_CD     R     cc_t_MS     1
bb     bbb      Cc_CD     PK_CC_CD     R     cc_t_MS     2
bb_v     bb_vsr     S_NUM     PK_S_NUM      R     bb_v      3
cC_HS_MS     cc_hs_CD     cc_CD     PK_CC_CD     R     cc_t_MS     4
