Running a user defined function in a SELECT statement - MySQL -

-

मेरे पास unzip नामक एक सरल तालिका है। इसके पास तीन कॉलम हैं- - आईडी INT अनिर्धारित नल एटऑन्ग्रेमेंट , share_src VARCHAR (30) नल , निर्माता INT अनसॉल्टेड नहीं नल । < / P>

मेरे पास checkSrc नामक फ़ंक्शन भी है, जो नहीं या हाँ देता है जब एक share_src इसे पैरामीटर के रूप में प्रदान किया जाता है

मैं उन सभी पंक्तियों को वापस करना चाहता हूं जहां निर्माता है 10 और ( share_src रिक्त है या फ़ंक्शन चेक से परिणामस्वरूप हाँ हाँ < / code>)।

वर्तमान में मैं यह कर रहा हूं 

  SELECT * से WHERE creator = 12 और (share_src IS NULL) checkSrc (share_src) = 'yes') खोलें;   
 लेकिन यह एक त्रुटि में परिणाम है क्वेरी में समस्या क्या है? मदद के लिए बहुत धन्यवाद ..   
 
 
 SELECT * से खोलें WHERE निर्माता = 12 और (share_src NULL या जांच करें SRC (share_src) = 'yes');  
 कोशिश करो और मुझे बताएं।  
 जांचें कि फ़ंक्शन सही डेटा प्रकार वापस कर रहा है या नहीं। इसकी वापसी की स्ट्रिंग प्रकार देखें।

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.
