I suddenly started getting these error messages when I try to open the charts of some patients:

ERROR: query failed: SELECT * FROM `` WHERE `pid`=?

Error: Incorrect table name ''

There seems to be no pattern - about 10% of patients generate this error.

OpenEMR 4.1.1 patch 9.  on Debian Linux

What could be the cause and potential fix.

Any help appreciated,
