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

Description

odbc_tables(
 Odbc\Connection $odbc,
 ?string $catalog = null,
 ?string $schema = null,
 ?string $table = null,
 ?string $types = null
): Odbc\Result|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 object, 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 object 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
8.4.0	`odbc` expects an Odbc\Connection instance now; previously, a resource was expected.
8.4.0	This function returns an Odbc\Result instance now; previously, a resource was returned.
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] =>
)
