odbc_tables

(PHP 4, PHP 5)

odbc_tables指定したデータソースに保存されたテーブルの名前のリストを取得する

説明

resource odbc_tables ( resource $connection_id [, string $qualifier [, string $owner [, string $name [, string $types ]]]] )

指定した範囲の全てのテーブルリストを得ます。

限定子、所有者、テーブル名を数えるために、 qualifierownernametable_type について以下のような特別な記号が使用可能です。

  • qualifier がパーセント記号 (%) のみで、 owner および name が空文字列であった場合、結果にはそのデータソースに関する 有効な限定子のリスト (NULL を有する TABLE_QUALIFIER カラム以外の 全てのカラム)が含まれます。
  • owner がパーセント記号 (%) のみで、 qualifier および name が空文字列の場合、結果にはその データソースに関する有効な所有者のリスト (NULL を有する TABLE_OWNER カラム以外の全てのカラム) が含まれます。
  • table_type がパーセント記号 (%) のみで、 qualifierownername が空文字列の場合、結果にはそのデータソースに 関する有効なテーブル型のリスト (NULL を有する TABLE_TYPE カラム以外の全てのカラム) が含まれます。

パラメータ

connection_id

ODBC 接続 ID。詳細は odbc_connect() を参照ください。

qualifier

修飾子。

owner

所有者。 検索パターン (ゼロ以上の文字にマッチする '%' や単一の文字にマッチする '_') を指定可能です。

name

名前。 検索パターン (ゼロ以上の文字にマッチする '%' や単一の文字にマッチする '_') を指定可能です。

types

table_type が空の文字列ではない場合、検索する型に ついてカンマで区切った値のリストを指定する必要があります。 各値は、シングルクオート(')で括るかまたは括らない形で指定可能です。 例えば、"'TABLE','VIEW'" または "TABLE, VIEW" となります。データソースが が指定したテーブル型をサポートしていない場合、 odbc_tables() はその型についていかなる結果も 返しません。

返り値

情報を含んでいる ODBC 結果 ID を返します。 失敗した場合に FALSE を返します。

結果セットのカラムは次のようになります。

  • TABLE_QUALIFIER
  • TABLE_OWNER
  • TABLE_NAME
  • TABLE_TYPE
  • REMARKS

結果セットは TABLE_TYPE、TABLE_QUALIFIER、TABLE_OWNER、TABLE_NAME の順番になります。

Here a Code for listing Table names
<?php
$dbh
= odbc_connect($dsn, $user, $pwd);

  
$result = odbc_tables($dbh);

  
$tables = array();
   while (
odbc_fetch_row($result)){
     if(
odbc_result($result,"TABLE_TYPE")=="TABLE")
       echo
"<br>".odbc_result($result,"TABLE_NAME");

   }
?>
You don't have views or System tables with.
Only simple tables in your database.

With regard to the note made on results not working.
Test the database with the easy:

odbc_result_all(odbc_tables($db));

$db is obviously a connected batadase. Then start to experiment:

if(!$odbcr=odbc_tables($db,"udb","", "%", "'TABLE'"))

"udb" is the DNS - aka 'name of my ODBC database in the Windows ODBC thingamy'. In result_all the full path was shown but I just used the name I assigned; either should work.

The second parameter "" is listed by result_all as "TABLE_SCHEM" and all items were "NULL", so I have put "".

The third parameter is "%". According to result_all this col is "TABLE_NAME", so I could have put the name of one of my tables, i.e. "Address".

In my case I have an Access database setup with several tables. In ODBC I have created a link. Running the all on everything result above shows a set of system tables which I do not need to know about at this point so I look at the result and then build my new table check using the "TABLE" string as the tables I am interested in are listed as "TABLE" under their "TABLE_TYPE" column.

A bit of an extension on the previous posts:

I had a whale of a time trying to make this command work .. the parameters were hard to decipher, and frequently my Apache module would just crash and burn when I tried to run it. I FINALLY figured out what was wrong ...

< -- assuming $conn is your odbc_connect --->

$tablelist=odbc_tables($conn);
$tablelist=odbc_result_all($tablelist);

simply doesn't work. I don't understand the exact logistics of it, but the only way I could get it to post the results was this:

$tablelist=odbc_result_all(odbc_tables($conn));

From there it was rather simple to add in parameters that fished out the results I wanted.

To repeat again: I do not understand why the 2nd method works and the 1st one does not. However, having struggled mightily with this function for almost 24 hours, posting this solution has proven to be greatly satisfying.

Here's how to get a list of all the tables in your database.. with an actual example of how its done and how to get the results.. and you don't need to put in schema and all that other crap

<?php
$conn
= odbc_connect("$database", "$username", "$password");
$tablelist = odbc_tables($conn);
while (
odbc_fetch_row($tablelist)) {
if (
odbc_result($tablelist, 4) == "TABLE")
echo
odbc_result($tablelist, 3) ."<br>";
}
?>

to understand what the above is doing,
use odbc_result_all($tablelist); this will show you EVERYTHING returned by odbc_tables() then you can look through it and see better how odbc_tables() works and what exactly it returns in the string to get a better idea on how to deal with it.
it would have saved me alot of time if i would have just taken a look at the full string returned by odbc_tables(), so i suggest you take the minute or two and look... here is an example of how to do it..which would have been helpful for me ;x.

<?php
$conn
= odbc_connect("$database", "$username", "$password");
$tablelist = odbc_tables($conn);
while (
odbc_fetch_row($tablelist)) {
echo
odbc_result_all($tablelist);
}
?>

hopefully this will help some people.. i have alot more to add about this but no time :(
so again hope this helps.

use odbc_tables($con, "%") to get a list of all available catalogs (databases).

use odbc_tables($con, "", "%") to get a list of all schemas available.

use odbc_tables($con, "", "", "", "%") to get a list of all table types available.

use odbc_tables($con, "my catalog", "my schema", "%", "'TABLE', 'VIEW'") to get a list of all tables available.

using odbc_tables($con, "%", "%", "%", "%") will return an empty array !

Before PHP 4.0.3 uou could use this function with 1 or 5 prarms. From 4.0.3 the function matches the documentation.

This probably works for a variety of formats, but if you want a list of *just* the table names from an SQL dsn source (I'm using MSSQL), here's the code.

<?php

# ... assign $dsn, $uid, & $pwd ...

$dbh = odbc_connect($dsn, $uid, $pwd);

   
$result = odbc_tables($dbh);
   
   
$tables = array();
    while (
odbc_fetch_row($result))
       
array_push($tables, odbc_result($result, "TABLE_NAME") );
   
    foreach(
$tables as $t ) {
        echo
"$t\n";   
    }

?>
