Digg odbc_tables
Get the list of table names stored in a specific data source
(PHP 4, PHP 5)
Lists all tables in the requested range. Returns an ODBC result
identifier containing the information or The result set has the following columns:
The result set is ordered by TABLE_TYPE, TABLE_QUALIFIER, TABLE_OWNER and TABLE_NAME. The owner and name arguments accept search patterns ('%' to match zero or more characters and '_' to match a single character). To support enumeration of qualifiers, owners, and table types, the following special semantics for the qualifier, owner, name, and table_type are available:
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. See also odbc_tableprivileges() to retrieve associated privileges. Examples ( Source code ) » odbc_tables Code Examples / Notes » odbc_tablesiggvopvantoodlwin
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($db,"udb","", "%", "'TABLE'")) "udb" is the DNS - aka 'name of my ODBC database in the Windows ODBC thingamy'. In result_all the full path was shown but I just used the name I assigned; either should work. The second parameter "" is listed by result_all as "TABLE_SCHEM" and all items were "NULL", so I have put "". The third parameter is "%". According to result_all this col is "TABLE_NAME", so I could have put the name of one of my tables, i.e. "Address". In my case I have an Access database setup with several tables. In ODBC I have created a link. Running the all on everything result above shows a set of system tables which I do not need to know about at this point so I look at the result and then build my new table check using the "TABLE" string as the tables I am interested in are listed as "TABLE" under their "TABLE_TYPE" column. fmk
use odbc_tables($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. pmains
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"; } ?> liquidicee
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 $conn = odbc_connect("$database", "$username", "$password"); $tablelist = odbc_tables($conn); while (odbc_fetch_row($tablelist)) { if (odbc_result($tablelist, 4) == "TABLE") echo "" . odbc_result($tablelist, 3) ." "; } to understand what the above is doing, use odbc_result_all($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.

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($result,"TABLE_TYPE")=="TABLE") echo" ".odbc_result($result,"TABLE_NAME"); } ?> You don't have views or System tables with. Only simple tables in your database. kthejoker
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. |
