sql panel failures (after #347)

[w-diesel]

Tried current trunk branch, with #347. I've got the HTTP/500 error, on some sql queries, when I wanted see the 'select'/'explain'.

Traceback:

I did not mentioned this before:
this occurs when using SQLite, with any SQL-query.

There is another problem with current trunk.
SQL queries with 'LIKE' statement will fail when you try see the "select"/"explain".
(tested with postgresql)
e.g. LIKE '445%'

ValueError at /__debug__/sql_select/
unsupported format character ''' (0x27) at index 284
