Description:
SHOW CREATE TABLE tablename SQL QUERY generates a statement with pairs of single quotes (“'”) surrounding whatever is quoted.

How to repeat:
execute a SHOW CREATE TABLE tablename query

Note that in the resulting CREATE TABLE query statement, values which are quoted are surrounded by PAIRS of single quotes.  i.e. (“''”) instead of (“'”).

e.g.

  `Col2` int(11) NOT NULL DEFAULT ''0'',

SQL Editor flags this line with a red X until the extra single quotes are deleted.

Suggested fix:
Enclose with single quotes, not a pair of single quotes.

Clarification: The 'Create Table' Column of the 'Results' tab correctly shows that values are enclosed with single quotes.  

Right clicking on the resulting 'Create Table' statement in the 'Results' tab, and selecting 'Copy field content' seems to be where the duplicate single quotes are added (i.e. pasting will show the duplicate single quotes)

Quotes are only required for strings and should be avoided totally with numbers.
