Beskrivelse

array sqlite_fetch_column_types ( string $table_name , resource $dbhandle [, int $result_type ] )

Object oriented style (method):

SQLiteDatabase
array fetchColumnTypes ( string $table_name [, int $result_type ] )

sqlite_fetch_column_types() returns an array of column data types from the specified table_name table.

Parameterliste

table_name

The table name to query.

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_ASSOC is the default for this function.

Returneringsværdier

Returns an array of column data types; FALSE on error.

The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration option.
