Detailed Description

These functions allow you to access rows in a result set. If the result is unbuffered, you can read and buffer rows one at a time. If the rows are buffered in the result, the drizzle_row_next() and related functions can be used.

Function Documentation

◆ drizzle_row_read()

uint64_t drizzle_row_read	(	drizzle_result_st *	result,
		drizzle_return_t *	ret_ptr )

Get next row number for unbuffered results. Use the drizzle_field* functions to read individual fields after this function succeeds.

Definition at line 22 of file row.c.

◆ drizzle_row_buffer()

drizzle_row_t drizzle_row_buffer	(	drizzle_result_st *	result,
		drizzle_return_t *	ret_ptr )

Read and buffer one row. The returned row must be freed by the caller with drizzle_row_free().

Parameters

[in,out]	result	pointer to the result structure to read from.
[out]	ret_pointer	Standard drizzle return value.

Returns: the row that was read, or NULL if there are no more rows.

Definition at line 35 of file row.c.

◆ drizzle_row_free()

void drizzle_row_free	(	drizzle_result_st *	result,
		drizzle_row_t	row )

Free a row that was buffered with drizzle_row_buffer().

Definition at line 88 of file row.c.

◆ drizzle_row_field_sizes()

size_t * drizzle_row_field_sizes ( drizzle_result_st * result )

Get an array of all field sizes for buffered rows.

Definition at line 98 of file row.c.

◆ drizzle_row_next()

drizzle_row_t drizzle_row_next ( drizzle_result_st * result )

Get next buffered row from a fully buffered result.

Definition at line 103 of file row.c.

◆ drizzle_row_prev()

drizzle_row_t drizzle_row_prev ( drizzle_result_st * result )

Get previous buffered row from a fully buffered result.

Definition at line 113 of file row.c.

◆ drizzle_row_seek()

void drizzle_row_seek	(	drizzle_result_st *	result,
		uint64_t	row )

Seek to the given buffered row in a fully buffered result.

Definition at line 123 of file row.c.

◆ drizzle_row_index()

drizzle_row_t drizzle_row_index	(	drizzle_result_st *	result,
		uint64_t	row )

Get the given buffered row from a fully buffered result.

Definition at line 129 of file row.c.

◆ drizzle_row_current()

uint64_t drizzle_row_current ( drizzle_result_st * result )

Get current row number.

Definition at line 137 of file row.c.
