我创建了一个表名emp_inforamtion,检查表是否存在于数据库中,如果没有,则创建表,然后将bank表中的数据插入emp_information表。
DECLARE
ncount NUMBER;
v_sql VARCHAR2(4000);
CURSOR c1
IS
SELECT bank_code,
center_code,
bank_name,
logo
FROM bank
WHERE bank_code ='607143';
BEGIN
SELECT COUNT(1) INTO ncount FROM tab WHERE tname LIKE '%EMP_INFORMATION%';
IF (ncount <= 0) THEN
DBMS_OUTPUT.PUT_LINE (ncount || 'count');
BEGIN
v_sql :=' CREATE TABLE EMP_INFORMATION
(
emp_id VARCHAR2(3),
emp_name VARCHAR2(20),
emp_salary VARCHAR2(3),
emp_department VARCHAR2(3)
)';
EXECUTE immediate v_sql;
COMMIT;
BEGIN
FOR i IN c1
LOOP
INSERT
INTO EMP_INFORMATION
(
emp_id,
emp_name,
emp_salary,
emp_department
)
VALUES
(
i.bank_code,
i.bank_name,
i.center_code,
i.logo
);
END LOOP;
END;
END;
END IF;
end;
/
执行上述光标后发现以下错误:
ORA-06550:第30行,第16列:PL / SQL:ORA-00942:表或视图不存在
ORA-06550:第29行,第11列:PL / SQL:忽略SQL语句

在匿名块中使用execute immediate创建表时,请使用execute immediate将数据插入其中。
DECLARE
ncount NUMBER;
v_sql VARCHAR2(4000);
CURSOR c1
IS
SELECT bank_code,
center_code,
bank_name,
logo
FROM bank
WHERE bank_code ='607143';
BEGIN
SELECT COUNT(1) INTO ncount FROM tab WHERE tname LIKE '%EMP_INFORMATION%';
IF (ncount <= 0) THEN
DBMS_OUTPUT.PUT_LINE (ncount || 'count');
BEGIN
v_sql :=' CREATE TABLE EMP_INFORMATION
(
emp_id VARCHAR2(3),
emp_name VARCHAR2(20),
emp_salary VARCHAR2(3),
emp_department VARCHAR2(3)
)';
EXECUTE IMMEDIATE v_sql;
BEGIN
FOR i IN c1
LOOP
EXECUTE IMMEDIATE 'INSERT
INTO EMP_INFORMATION
(
emp_id,
emp_name,
emp_salary,
emp_department
)
VALUES
(
:a,
:b,
:c,
:d
)' using i.bank_code, i.bank_name, i.center_code, i.logo;
END LOOP;
END;
END;
END IF;
end;
