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.

SQLITE_ASSOCSQLITE_BOTH 返回的列名会依照 sqlite.assoc_case 配置选项的值决定大小写。

范例

Example #1 Procedural example

<?php
$db 
sqlite_open('mysqlitedb');
sqlite_query($db'CREATE TABLE foo (bar varchar(10), arf text)');
$cols sqlite_fetch_column_types('foo'$dbSQLITE_ASSOC);

foreach (
$cols as $column => $type) {
    echo 
"Column: $column  Type: $type ";
}
?>

Example #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 ";
}
?>

以上例程会输出:

Column: bar  Type: VARCHAR
Column: arf  Type: TEXT
