Name
sqlite3_column_name() — Get the name of a result column
Definition
const char* sqlite3_column_name( sqlite3_stmt* stmt, int cidx ); const void* sqlite3_column_name16( sqlite3_stmt* stmt, int cidx );
-
stmt A prepared statement.
-
cidx A column index. The first column has an index of zero (
0).- Returns
The name of a result column.
Description
These functions return the name of a result column. This is the
name provided by the AS
clause of a select header. If no AS clause was provided, the name will be
derived from the expression used to define the SELECT header. The format of
derived names is not defined by the SQL standard and may change
from one release of SQLite to another. If an application depends
on explicit column names, it should always use AS clauses in the select
header.
Returned pointers will remain valid until sqlite3_finalize() is called on
the statement, or until one of these functions is called with
the same column index. SQLite will take care of all memory
management for the buffers returned by these functions.
