Return an array of column types from a particular table

sqlite_fetch_column_types

SQLiteDatabase->fetchColumnTypes

(PHP 5)

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

Description

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.

Parameters

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.

Return Values

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.

ChangeLog

Version Description
5.1.0 Added result_type

Examples

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', $db, SQLITE_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";
}
?>

The above example will output:

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