int sqlite3_data_count(sqlite3_stmt *pStmt);

The sqlite3_data_count(P) interface returns the number of columns in the current row of the result set of prepared statement P. If prepared statement P does not have results ready to return (via calls to the sqlite3_column_*() of interfaces) then sqlite3_data_count(P) returns 0- The sqlite3_data_count(P) routine also returns 0 if P is a NULL pointer- The sqlite3_data_count(P) routine returns 0 if the previous call to sqlite3_step(P) returned SQLITE_DONE. The sqlite3_data_count(P) will return non-zero if previous call to sqlite3_step(P) returned SQLITE_ROW, except in the case of the PRAG
