odbc_tables

(PHP 4, PHP 5, PHP 7, PHP 8)

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

说明

odbc_tables(
    resource $odbc,
    ?string $catalog = null,
    ?string $schema = null,
    ?string $table = null,
    ?string $types = null
): 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, table, and table_type are available:

  • If catalog is a single percent character (%) and schema and table 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 table 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 table 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

odbc

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。

table

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.

更新日志

版本 说明
8.0.0 schema, table and types are now nullable.

范例

示例 #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] =>
)
