Using SQLite

Name

sqlite3_column_database_name() — Get the source database name of a result column

Definition

const char* sqlite3_column_database_name(   sqlite3_stmt* stmt, int cidx );
const void* sqlite3_column_database_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 logical name of the source database for the given result column.

Description

These functions return the unaliased logical name of the source database that is associated with a SELECT result column. 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.

Data is only available for result columns that are derived directly from a column reference. If a result column is defined as an expression or subquery, a NULL will be returned.

These functions are only available if the SQLite library was compiled with the SQLITE_ENABLE_COLUMN_METADATA build option.
