It means that you are violating the rules in some way.  SQLite is nice
and returned error 21 instead of segfaulting.

To get more information, run your application in a debugger and set a
breakpoint on the sqlite3MisuseError() function.  Then show us a stack
trace when that breakpoint is hit.

[W J]

Hello ,

I'm using sqlite3_get_table() to query some information from sqlite. but 
sometimes( not every time), I got error return value: 21.
#define SQLITE_MISUSE  21   /* Library used incorrectly */

the version information is follow:
#define SQLITE_VERSION"3.8.4.3"
#define SQLITE_VERSION_NUMBER 3008004
#define SQLITE_SOURCE_ID  "2014-04-03 16:53:12 
a611fa96c4a848614efe899130359c9f6fb889c3"

What is the real meaning of this error? How to correct it?
