sqlite_fetch_column_types

Return an array of column types from a particular table (PHP 5)
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.

Examples

Example 2333. 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 2334. Object-oriented example

copy to clipboard

<?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:

copy to clipboard

Column: bar  Type: VARCHAR

Column: arf  Type: TEXT

This function, and the OO version, is bugged in PHP <= 5.0.1, locking the database until you restart the webserver. http://bugs.php.net/bug.php?id=29476

10-jan-2005 11:01

The problem with the permanently locked database file when using this function still seems to exist in PHP 5.0.3 (tested on win32). However, you can get all the information you need about the fields of a table by using this query: PRAGMA table_info(name_of_your_table);

enthusiast

If I (OO version) try to add the contant SQLITE_ASSOC, (exactly as listed in the above example) it generates the following error: SQLiteDatabase::fetchColumnTypes() expects exactly 1 parameter, 2 given in C:\.... If I remove it completely, it returns the associative array I expected.
