sqlite_unbuffered_query

(PHP 5)

(no version information, might be only in CVS)

SQLiteDatabase->unbufferedQuery -- Execute a query that does not prefetch and buffer all data

Description

resource sqlite_unbuffered_query ( resource dbhandle, string query [, int result_type] )

resource sqlite_unbuffered_query ( string query, resource dbhandle [, int result_type] )

Object oriented style (method):

class SQLiteDatabase {

SQLiteUnbuffered unbufferedQuery ( string query [, int result_type] )

}

sqlite_unbuffered_query() is identical to sqlite_query() except that the result that is returned is a sequential forward-only result set that can only be used to read each row, one after the other.

This function is ideal for generating things such as HTML tables where you only need to process one row at a time and don't need to randomly access the row data.

Note: Functions such as sqlite_seek(), sqlite_rewind(), sqlite_next(), sqlite_current(), and sqlite_num_rows() do not work on result handles returned from sqlite_unbuffered_query().

Parameters

query: The query to be executed.
dbhandle: The SQLite Database resource; returned from sqlite_open () when used procedurally. This parameter is not required when using the object-oriented method.
result_type: The optional result_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC will return only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers). SQLITE_BOTH will return both associative and numerical indices. SQLITE_BOTH is the default for this function.

Note: Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first, where the dbhandle parameter is the first parameter to the function.

Return Values

Returns a result handle or FALSE on failure.

sqlite_unbuffered_query() returns a sequential forward-only result set that can only be used to read each row, one after the other.
