SQLITE3_DATA_COUNT(3)      Library Functions Manual      SQLITE3_DATA_COUNT(3)

NAME
     sqlite3_data_count - number of columns in a result set

SYNOPSIS
     #include <sqlite3.h>

     int
     sqlite3_data_count(sqlite3_stmt *pStmt);

DESCRIPTION
     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() family 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 PRAGMA incremental_vacuum where it
     always returns zero since each step of that multi-step pragma returns 0
     columns of data.

IMPLEMENTATION NOTES
     These declarations were extracted from the interface documentation at
     line 4985.
