use of regex in mysql

I have query as shown below.

SELECT myWord, LEAST ( if (Locate('0',myWord) >0,Locate('0',myWord),999), if (Locate('1',myWord) >0,Locate('1',myWord),999), if (Locate('2',myWord) >0,Locate('2',myWord),999), if (Locate('3',myWord) >0,Locate('3',myWord),999), if (Locate('4',myWord) >0,Locate('4',myWord),999), if (Locate('5',myWord) >0,Locate('5',myWord),999), if (Locate('6',myWord) >0,Locate('6',myWord),999), if (Locate('7',myWord) >0,Locate('7',myWord),999), if (Locate('8',myWord) >0,Locate('8',myWord),999), if (Locate('9',myWord) >0,Locate('9',myWord),999) ) as myPos FROM myTable; 

Using this query, I am finding the position of first integer in a string.

My Question Is

Using regex how can I eliminate those 10 lines that I have as shown below.

 if (Locate('0',myWord) >0,Locate('0',myWord),999), if (Locate('1',myWord) >0,Locate('1',myWord),999), if (Locate('2',myWord) >0,Locate('2',myWord),999), if (Locate('3',myWord) >0,Locate('3',myWord),999), if (Locate('4',myWord) >0,Locate('4',myWord),999), if (Locate('5',myWord) >0,Locate('5',myWord),999), if (Locate('6',myWord) >0,Locate('6',myWord),999), if (Locate('7',myWord) >0,Locate('7',myWord),999), if (Locate('8',myWord) >0,Locate('8',myWord),999), if (Locate('9',myWord) >0,Locate('9',myWord),999) 

Any idea how to get this done?
