/**
* 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.)
*
*
*
*
* @param resource $connection_id The ODBC connection identifier,
* see odbc_connect for details.
* @param string $catalog The catalog ('qualifier' in ODBC 2 parlance).
* @param string $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.
* @param string $name The name.
* This parameter accepts the following search patterns:
* % to match zero or more characters,
* and _ to match a single character.
* @param string $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 resource Returns an ODBC result identifier containing the information.
*
* The result set has the following columns:
*
* TABLE_CAT
* TABLE_SCHEM
* TABLE_NAME
* TABLE_TYPE
* REMARKS
*
* Drivers can report additional columns.
* @throws UodbcException
