odbc_tables — Get the list of table names stored in a specific data source
說明
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
catalogis a single percent character (%) andschemaandtableare 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
schemais a single percent character (%) andcatalogandtableare 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_typeis a single percent character (%) andcatalog,schemaandtableare 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.)
參數
-
odbc ODBC 連線識別符號，詳見 odbc_connect()。
-
catalog The catalog ('qualifier' in ODBC 2 parlance).
-
schema The schema ('owner' in ODBC 2 parlance). 此參數接受下列查詢模式：
%來匹配零到多個字元，_來匹配單個字元。-
table The name. 此參數接受下列查詢模式：
%來匹配零到多個字元，_來匹配單個字元。-
types If
table_typeis 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'orTABLE, VIEW. If the data source does not support a specified table type, odbc_tables() does not return any results for that type.
返回值
Returns an ODBC result identifier containing the information
或者在失敗時返回 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.
更新日誌

範例
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
}
?> 以上例程的輸出類似於：
Array
(
[TABLE_CAT] => SalesOrders
[TABLE_SCHEM] => dbo
[TABLE_NAME] => Orders
[TABLE_TYPE] => TABLE
[REMARKS] =>
)
