如何解决ORA-00001：违反了唯一约束（TICL_NBFC.IFSC_CODE_UNIQUE） [英] how to resolve ORA-00001: unique constraint (TICL_NBFC.IFSC_CODE_UNIQUE) violated

问题描述

谢谢所有

thanks all

ALTER TABLE bank_master
add CONSTRAINT Ifsc_Code_unique UNIQUE (IFSC_CODE);

我的代码有效。

my this code worked .

sb.Append(" INSERT INTO BANK_MASTER ");
sb.Append(" (ID, BANK_NAME,BRANCH_NAME,IFSC_CODE,MICR_CODE,ADDRESS_ID,MAKER_ID,MAKER_DATETIME,  COMPANY_ID) ");
sb.Append(" VALUES (Bank_Master_Id_Seq.NEXTVAL, :BANK_NAME,:BRANCH_NAME,:IFSC_CODE,:MICR_CODE,:ADDRESS_ID,:MAKER_ID,  TO_DATE(:MAKERDATETIME, 'DD-MM-YYYY'), :i_COMPANY_ID) ");

s_dsnstr = o_Cls_Utility.utl_fnGetDSNStr(SessionHandle.Current.SessionCompanyCode);
OracleConnect o_Cls_OracleConnect = new OracleConnect(s_dsnstr);
o_Cls_OracleConnect.OracleCommand_PreInit(sb.ToString());
o_Cls_OracleConnect.Parameter_String("BANK_NAME", BANK_NAME);
o_Cls_OracleConnect.Parameter_String("BRANCH_NAME", BRANCH_NAME);
o_Cls_OracleConnect.Parameter_String("IFSC_CODE", IFSC_CODE);
o_Cls_OracleConnect.Parameter_String("MICR_CODE", MICR_CODE);
o_Cls_OracleConnect.Parameter_String("ADDRESS_ID", ADDRESS_ID);
o_Cls_OracleConnect.Parameter_String("MAKER_ID", MAKER_ID);
o_Cls_OracleConnect.Parameter_String("MAKERDATETIME", MAKERDATETIME);
o_Cls_OracleConnect.Parameter_Int32("i_COMPANY_ID", Company_ID);


o_Cls_OracleConnect.ExecNonQuery();
sb.Remove(0, sb.Length);
