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 = SQLITE_ASSOC
] )
public array SQLiteDatabase::fetchColumnTypes
( string $table_name
[, int $result_type = SQLITE_ASSOC
] )
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_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 #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\n";
}
?>
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\n";
}
?>
The above example will output:
Column: bar Type: VARCHAR
Column: arf Type: TEXT
