sqlite_fetch_column_types

(PHP 5)

sqlite_fetch_column_types

(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_ASSOC is the default for this function.

返回值

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

由 SQLITE_ASSOC 和 SQLITE_BOTH 返回的列名会根据 sqlite.assoc_case 配置选项的值来决定大小写。

范例

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
