odbc_tables
(PHP 4, PHP 5)
odbc_tables — Get the list of table names stored in a specific data source
Описание
$connection_id
[, string $qualifier
[, string $owner
[, string $name
[, string $types
]]]] )Lists all tables in the requested range.
To support enumeration of qualifiers, owners, and table types,
the following special semantics for the
qualifier, owner,
name, and
table_type are available:
-
If
qualifieris a single percent character (%) andownerandnameare 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
owneris a single percent character (%) andqualifierandnameare 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 (%) andqualifier,ownerandnameare 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.)

connection_id -

-
qualifier -
The qualifier.
-
owner -
The owner. Accepts search patterns ('%' to match zero or more characters and '_' to match a single character).
-
name -
The name. Accepts search patterns ('%' to match zero or more characters and '_' to match a single character).
-
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'" or "TABLE, VIEW". If the data source does not support a specified table type, odbc_tables() does not return any results for that type.
Возвращаемые значения
Returns an ODBC result identifier containing the information
или FALSE в случае возникновения ошибки.
The result set has the following columns:
- TABLE_QUALIFIER
- TABLE_OWNER
- TABLE_NAME
- TABLE_TYPE
- REMARKS
The result set is ordered by TABLE_TYPE, TABLE_QUALIFIER, TABLE_OWNER and TABLE_NAME.

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.

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.
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.
