ALTER TABLE HA_ST01.TABLE_PO_SALES_MOM_TZC DROP COLUMN C_MONTH; CREATE procedure HA_ST01.PRO_PO_SALES_MOM_TZC(IN S_YM NVARCHAR(6),IN E_YM NVARCHAR(6)) LANGUAGE SQLSCRIPT AS BEGIN DELETE FROM HA_ST01.TABLE_PO_SALES_MOM_TZC WHERE C_MONTH BETWEEN :S_YM AND :E_YM; INSERT INTO TABLE_PO_SALES_MOM_TZC(C_MONTH,GROSSAMOUNT,GROSSAMOUNT_1,RATE_MOM)(SELECT C_MONTH FROM "_SYS_BIC"."HA20_TZC.DAY1/CAL_PO_TZC_01" WHERE C_MONTH BETWEEN :S_YM AND :E_YM); END;怎么修改

根据提供的代码，您需要将INSERT INTO语句中的表名从TABLE_PO_SALES_MOM_TZC修改为HA_ST01.TABLE_PO_SALES_MOM_TZC，以便与DELETE语句中的表名匹配。修改后的代码如下：

ALTER TABLE HA_ST01.TABLE_PO_SALES_MOM_TZC DROP COLUMN C_MONTH; 
CREATE procedure HA_ST01.PRO_PO_SALES_MOM_TZC(IN S_YM NVARCHAR(6),IN E_YM NVARCHAR(6)) 
LANGUAGE SQLSCRIPT AS  
BEGIN 
    DELETE FROM HA_ST01.TABLE_PO_SALES_MOM_TZC WHERE C_MONTH BETWEEN :S_YM AND :E_YM; 
    INSERT INTO HA_ST01.TABLE_PO_SALES_MOM_TZC(C_MONTH,GROSSAMOUNT,GROSSAMOUNT_1,RATE_MOM) 
    (SELECT C_MONTH FROM "_SYS_BIC"."HA20_TZC.DAY1/CAL_PO_TZC_01" WHERE C_MONTH BETWEEN :S_YM AND :E_YM);  
END;

请注意，如果表名或字段名有误，仍会提示错误。建议在修改代码之前，仔细检查表名、字段名和语法，以确保代码正确无误。
