ADODB_odbtp::ServerInfo (  ) 

Get server version info...

Returns:
An array with 2 elements: $arr['string'] is the description string, and $arr[version] is the version (also a string).

Reimplemented from ADOConnection.

Definition at line 40 of file adodb-odbtp.inc.php.

ADODB_odbtp::ErrorMsg (  ) 

Returns:
the last error message

Reimplemented from ADOConnection.

Definition at line 46 of file adodb-odbtp.inc.php.

Referenced by _connect().

ADODB_odbtp::ErrorNo (  ) 

Returns:
the last error number. Normally 0 means no error.

Reimplemented from ADOConnection.

Definition at line 52 of file adodb-odbtp.inc.php.

ADODB_odbtp::GenID ( seq = 'adodbseq',
start = 1 
)

Generates a sequence id and stores it in $this->genID; GenID is only available if $this->hasGenID = true;

Parameters:
seqname name of sequence to use
startID if sequence does not exist, start at this ID
Returns:
0 if not supported, otherwise a sequence id

Reimplemented from ADOConnection.

ADODB_odbtp::SelectDB ( dbName  ) 

Choose a database to connect to. Many databases do not support this.

Parameters:
dbName is the name of the database to select
Returns:
true or false

Reimplemented from ADOConnection.

Definition at line 264 of file adodb-odbtp.inc.php.

& ADODB_odbtp::MetaTables ( ttype = '',
showSchema = false,
mask = false 
)

Parameters:
ttype can either be 'VIEW' or 'TABLE' or false. If false, both views and tables are returned. "VIEW" returns only views "TABLE" returns only tables
showSchema returns the schema/user with the table name, eg. USER.TABLE
mask is the input mask - only supported by oci8 and postgresql
Returns:
array of tables for current database.

Reimplemented from ADOConnection.

Definition at line 274 of file adodb-odbtp.inc.php.

References ADOConnection::GetArray(), and ADOConnection::SetFetchMode().

& ADODB_odbtp::MetaColumns ( table,
upper = true 
)

List columns in a database as an array of ADOFieldObjects. See top of file for definition of object.

Parameters:
$table table name to query
$normalize makes table name case-insensitive (required by some databases) is optional database schema to use - not supported by all databases.
Returns:
array of ADOFieldObjects for current table.

Reimplemented from ADOConnection.

& ADODB_odbtp::MetaPrimaryKeys ( table,
owner = '' 
)

Returns:
an array with the primary key columns in it.

Reimplemented from ADOConnection.

Definition at line 341 of file adodb-odbtp.inc.php.

References ADOConnection::GetArray().

& ADODB_odbtp::MetaForeignKeys ( table,
owner = '',
upper = false 
)

Returns:
assoc array where keys are tables, and values are foreign keys

Reimplemented from ADOConnection.

Definition at line 358 of file adodb-odbtp.inc.php.

References ADOConnection::$false, and ADOConnection::GetArray().

ADODB_odbtp::BeginTrans (  ) 

Begin a Transaction. Must be followed by CommitTrans() or RollbackTrans().

Returns:
true if succeeded or false if database does not support transactions

Reimplemented from ADOConnection.

Definition at line 388 of file adodb-odbtp.inc.php.

ADODB_odbtp::CommitTrans ( ok = true  ) 

If database does not support transactions, always return true as data always commited

Parameters:
$ok set to false to rollback transaction, true to commit
Returns:
true/false.

Reimplemented from ADOConnection.

Definition at line 403 of file adodb-odbtp.inc.php.

References RollbackTrans().

ADODB_odbtp::RollbackTrans (  ) 

If database does not support transactions, rollbacks always fail, so return false

Returns:
true/false.

Reimplemented from ADOConnection.

Definition at line 414 of file adodb-odbtp.inc.php.

Referenced by CommitTrans().

& ADODB_odbtp::SelectLimit ( sql,
nrows = -1,
offset = -1,
inputarr = false,
secs2cache = 0 
)

Will select, getting rows from $offset (1-based), for $nrows. This simulates the MySQL "select * from table limit $offset,$nrows" , and the PostgreSQL "select * from table limit $nrows offset $offset". Note that MySQL and PostgreSQL parameter ordering is the opposite of the other. eg. SelectLimit('select * from table',3); will return rows 1 to 3 (1-based) SelectLimit('select * from table',3,2); will return rows 3 to 5 (1-based)

Uses SELECT TOP for Microsoft databases (when $this->hasTop is set) BUG: Currently SelectLimit fails with $sql with LIMIT or TOP clause already set

Parameters:
sql 
[offset] is the row to start calculations from (1-based)
[nrows] is the number of rows to get
[inputarr] array of bind variables
[secs2cache] is a private parameter only used by jlim
Returns:
the recordset ($rs->databaseType == 'array')

Reimplemented from ADOConnection.

Definition at line 424 of file adodb-odbtp.inc.php.

References ADOConnection::SelectLimit().

ADODB_odbtp::Prepare ( sql  ) 

Should prepare the sql statement and return the stmt resource. For databases that do not support this, we return the $sql. To ensure compatibility with databases that do not support prepare:

$stmt = $db->Prepare("insert into table (id, name) values (?,?)"); $db->Execute($stmt,array(1,'Jill')) or die('insert failed'); $db->Execute($stmt,array(2,'Joe')) or die('insert failed');

Parameters:
sql SQL to send to database
Returns:
return FALSE, or the prepared statement, or the original sql if if the database does not support prepare.

ADODB_odbtp::UpdateBlob ( table,
column,
val,
where,
blobtype = 'image' 
)

Update a blob column, given a where clause. There are more sophisticated blob handling functions that we could have implemented, but all require a very complex API. Instead we have chosen something that is extremely simple to understand and use.

Note: $blobtype supports 'BLOB' and 'CLOB', default is BLOB of course.

Usage to update a $blobvalue which has a primary key blob_id=1 into a field blobtable.blobcolumn:

UpdateBlob('blobtable', 'blobcolumn', $blobvalue, 'blob_id=1');

Insert example:

$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)'); $conn->UpdateBlob('blobtable','blobcol',$blob,'id=1');

Reimplemented from ADOConnection.
