odbc_tables

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

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

Description

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.)

Parameters

odbc

The ODBC connection identifier, see odbc_connect() for details.

catalog

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

schema

The schema ('owner' in ODBC 2 parlance). This parameter accepts the following search patterns: % to match zero or more characters, and _ to match a single character.

table

The name. This parameter accepts the following search patterns: % to match zero or more characters, and _ to match a single character.

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.

Return Values

Returns an ODBC result identifier containing the information or false on failure.

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.

Changelog

Version Description
8.0.0 schema, table and types are now nullable.

Examples

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
}
?>

The above example will output something similar to:

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