sqlite_fetch_column_types

(PHP 5)

(no version information, might be only in CVS)

SQLiteDatabase->fetchColumnTypes -- Return an array of column types from a particular table

说明

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

Object oriented style (method):

class 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.

参数

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_BOTH is the default for this function.

返回值

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.

例

例子 1. Procedural example

<?php $db = sqlite_open('mysqlitedb'); sqlite_query($db, 'CREATE TABLE foo (bar varchar(10), arf text)'); $cols = sqlite_fetch_column_types('foo', $db, SQLITE_ASSOC); foreach ($cols as $column => $type) { echo "Column: $column Type: $type"; } ?>

例子 2. Object-oriented example

<?php $db = new SQLiteDatabase('mysqlitedb'); $db->query('CREATE TABLE foo (bar varchar(10), arf text)'); $cols = $db->fetchColumnTypes('foo', SQLITE_ASSOC); foreach ($cols as $column => $type) { echo "Column: $column Type: $type"; } ?>
上例将输出：
Column: bar Type: VARCHAR Column: arf Type: TEXT
