我必须执行一个SQL文件（我不太了解SQL，我只需执行它）但是有一个我不明白的错误：

错误：检查编译器日志错误PACKAGE USER1.TST_MAI_FILTER：LINE / COL ERROR 29/1 PLS-00103：遇到符号“CREATE”

这是PACKAGE USER1.TST_MAI_FILTER：

CREATE OR REPLACE PACKAGE TST_MAI_FILTER IS

FUNCTION TRADE_TYPE
RETURN NUMBER;

FUNCTION ORDER_TYPE
RETURN NUMBER;

FUNCTION MRKT_EVT_TYPE
RETURN NUMBER;

FUNCTION DAILY_DATA_TYPE
RETURN NUMBER;

PROCEDURE log_mai_filter(p_run_id NUMBER, p_config_id NUMBER);

PROCEDURE is_valid_filter
(p_mai_class_id IN NUMBER,
 p_type_id IN NUMBER,
 v_where  CLOB);

END TST_MAI_FILTER;
/

我正在使用Oracle SQL Developer（Oracle Database 12c企业版12.2.0.1.0版 - 64位 生产环境 版） .

编辑：这是第29行：

CREATE SEQUENCE S_TRD START WITH 1 INCREMENT BY 1 MINVALUE 1 CACHE 20 NOORDER;

这是包的其余部分但是直到那里才开始，因为开发人员在此错误之后停止：
