sql - Why is it showing trigger 'AICHAT.BI_USERDATA' is invalid and failed re-validation as an error? -

- 

  बनाएँ तालिका "USERDATA" ("USERDATAID" NUMBER, "FNAME" VARCHAR2 (4000), "USERNAME" VARCHAR2 (4000), "पासवर्ड" VARCHAR2 (4000), "संपर्क" VARCHAR2 (4000), कॉन्ट्रैक्ट "USERDATA_PK" प्राथमिक कुंजी ("USERDATAID" सक्षम) सक्षम करें या ट्रिगर बनाएं "BI_USERDATA" प्रत्येक पंक्ति के लिए "USERDATA" पर सम्मिलित होने से पहले "USERDATA_SEQ" का चयन करें। में निम्न: NEW.USERDATAID से दोहरी; समाप्त; / वैकल्पिक ट्रिगर "BI_USERDATA" सक्षम /

यह तालिका और ट्रिगर बनाने के लिए मेरा कोड है लेकिन यह दर्शाता है कि "AICHAT.BI_USERDATA 'अमान्य है और एक त्रुटि के रूप में फिर से सत्यापन विफल रहा है जब भी मैं एक नया मूल्य डालने का प्रयास करता हूं। इसके साथ क्या गलत है?
