odbc_tables — Get the list of table names stored in a specific data source
$odbc
, string|null $catalog = null
, string|null $schema = null
, string|null $table = null
, string|null $types = null
) : resource|falseLists 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.)
odbcODBC 连接标识符，详见 odbc_connect()。
catalogThe 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.
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_CATTABLE_SCHEMTABLE_NAMETABLE_TYPEREMARKS
The result set is ordered by TABLE_TYPE, TABLE_CAT,
TABLE_SCHEM and TABLE_NAME.
| 版本 | 说明 |
|---|---|
| 8.0.0 |
schema, table and types
are now nullable.

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] =>
)
