odbc_tables — Get the list of table names stored in a specific data source
$odbc
,$catalog
= null
,$schema
= null
,$table
= null
,$types
= null
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:
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.) 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.) 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.) 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.
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
The result set is ordered by TABLE_TYPE
, TABLE_CAT
, TABLE_SCHEM
and TABLE_NAME
.

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] => )
