php - In mysql, how can I select the numeric portion of a field? -

-

मेरे पास एक मुक्त फॉर्म फोन नंबर युक्त तालिका है (जैसे '123-456-7890', '(987) 654- 3210 ', या' 123.456.7890 ') और मैं उन्हें एक संख्यात्मक स्ट्रिंग के साथ खोज रहा हूं- जैसे,' 123456 '।

अभी, मुझे प्रतिस्थापित करने का एक स्थान (प्रतिस्थापित करना है प्रतिस्थापन (गैर-संख्यात्मक वर्णों को बाहर निकालने के लिए विज्ञापन न्यसम फ़ंक्शंस बदलें। फिर खोज के लिए 'पसंद' का उपयोग करें।

किसी को भी किसी आधार पर फ़ील्ड से केवल कुछ वर्णों का चयन करने के लिए सरल तरीके से पता है प्रकार, स्थिति नहीं है?

आप Mygeq में regex का उपयोग कर सकते हैं - 

  SELECT * FROM `table` जहां WHERE` फोन` REGEXP '^ [12345]'

यहां एक काम है।

python - Strange behavior using PyQt4's 'pyqtSlot' decorator before another decorator -

-
I have a strange problem with using the QtCore.pyqtSlot decorator in front of the function decorated with a different decorator. The problem below shows this problem, it immediately provides a low QT program with a single button. When pressing a button, the following happens: (1) The signal 'signal_A' and 'signal_B' sequence are connected to method_A and method_B ​​respectively. (2) signal_A and signal_B signals are emitted. (3) The required behavior is that the method_A and method_B ​​are executed. However, it turns out that both signal_A and signal_B trigger method_A, or method_B ​​(oddly, this is nondeterministic, and different for each part of the program!). It appears to be a bug. This issue is present when PyQt4 binding is used in Qt. It is not present when using PySide (use the '-pyside' parameter to verify) I have seen both problems in Python 2 and 3, and both in Windows and Linux This issue is related to the insertion of a decorator be...

Message + environment. Newline); }} Maybe you search for the behavior provided by Applic...
