$query
[, int $result_type = SQLITE_BOTH
[, string &$error_msg
]] )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().
dbhandle
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
query
The query to be executed.
Data inside the query should be properly escaped.
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.
error_msg
The specified variable will be filled if an error occurs. This is specially important because SQL syntax errors can't be fetched using the sqlite_last_error() function.
Note: Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first, where the
dbhandleparameter is the first parameter to the function.
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.
