Column Names In A Result Set

+
+
+const char *sqlite3_column_name(sqlite3_stmt*, int N);
+const void *sqlite3_column_name16(sqlite3_stmt*, int N);
+
+

+These routines return the name assigned to a particular column +in the result set of a SELECT statement. The sqlite3_column_name() +interface returns a pointer to a zero-terminated UTF-8 string +and sqlite3_column_name16() returns a pointer to a zero-terminated +UTF-16 string. The first parameter is the prepared statement +that implements the SELECT statement. The second parameter is the +column number. The leftmost column is number 0.

+ +

The returned string pointer is valid until either the prepared statement +is destroyed by sqlite3_finalize() or until the statement is automatically +reprepared by the first call to sqlite3_step() for a particular run +or until the next call to +sqlite3_column_name() or sqlite3_column_name16() on the same column.

+ +

If sqlite3_malloc() fails during the processing of either routine +(for example during a conversion from UTF-8 to UTF-16) then a +NULL pointer is returned.

+ +

The name of a result column is the value of the "AS" clause for +that column, if there is an AS clause. If there is no AS clause +then the name of the column is unspecified and may change from +one release of SQLite to the next. +
