odbc_tables — Get the list of table names stored in a specific data source

说明

odbc_tables ( resource $connection_id [, string $catalog [, string $schema [, string $name [, string $types ]]]] ) : resource|false

Lists all tables in the requested range.

To support enumeration of qualifiers, owners, and table types, the following special semantics for the catalog, schema, name, and table_type are available:

• If catalog is a single percent character (%) and schema and name are empty strings, then the result set contains a list of valid qualifiers for the data source. (All columns except the TABLE_QUALIFIER column contain NULLs.)
• If schema is a single percent character (%) and catalog and name are empty strings, then the result set contains a list of valid owners for the data source. (All columns except the TABLE_OWNER column contain NULLs.)
• If table_type is a single percent character (%) and catalog, schema and name are empty strings, then the result set contains a list of valid table types for the data source. (All columns except the TABLE_TYPE column contain NULLs.)

参数

connection_id

ODBC 连接标识符，详见 odbc_connect()。

catalog

The catalog ('qualifier' in ODBC 2 parlance).

schema

The schema ('owner' in ODBC 2 parlance). 此参数接受下列查询模式： % 来匹配零到多个字符， _ 来匹配单个字符。

name

The name. 此参数接受下列查询模式： % 来匹配零到多个字符， _ 来匹配单个字符。

types

If table_type is not an empty string, it must contain a list of comma-separated values for the types of interest; each value may be enclosed in single quotes (') or unquoted. For example, 'TABLE','VIEW' or TABLE, VIEW. If the data source does not support a specified table type, odbc_tables() does not return any results for that type.

返回值

Returns an ODBC result identifier containing the information 或者在失败时返回 false.

The result set has the following columns:

• TABLE_CAT
• TABLE_SCHEM
• TABLE_NAME
• TABLE_TYPE
• REMARKS

Drivers can report additional columns. The result set is ordered by TABLE_TYPE, TABLE_CAT, TABLE_SCHEM and TABLE_NAME.

范例

Example #1 List Tables in a Catalog

<?php$conn = odbc_connect($dsn, $user, $pass);$tables = odbc_tables($conn, 'SalesOrders', 'dbo', '%', 'TABLE');while (($row = odbc_fetch_array($tables))) {    print_r($row);    break; // further rows omitted for brevity}?>

以上例程的输出类似于：

Array
(
    [TABLE_CAT] => SalesOrders
    [TABLE_SCHEM] => dbo
    [TABLE_NAME] => Orders
    [TABLE_TYPE] => TABLE
    [REMARKS] =>
)
