Using SQLite

Name

sqlite3_data_count() — Get the number of valid result columns in a statement

Definition

int sqlite3_data_count( sqlite3_stmt* stmt );

stmt

A prepared statement.

Returns

The number of columns available in a prepared statement.

Description

This function returns the number of columns available in a row result. Column indexes start at zero (0), so if this function returns 5, value column indexes are 0 to 4. The value zero (0) will be returned if there is no current result row.

This function is almost identical to sqlite3_column_count(). The main difference is that this function will return zero (0) if no valid result row is currently available (for example, before sqlite3_step() is called), while sqlite3_column_count() will always return the number of expected columns, even if no row is currently available.
