Member Function Documentation

ADODB_db2::DBTimeStamp ( ts  ) 

Converts a timestamp "ts" to a string that the database can understand.

Parameters:
ts a timestamp in Unix date time format.
Returns:
timestamp string in database timestamp format

Reimplemented from ADOConnection.

Definition at line 124 of file adodb-db2.inc.php.

References ADORecordSet::UnixTimeStamp().

ADODB_db2::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 198 of file adodb-db2.inc.php.

References ADOConnection::ServerInfo().

ADODB_db2::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.

Definition at line 248 of file adodb-db2.inc.php.

References ADOConnection::GetOne().

ADODB_db2::ErrorMsg (  ) 

Returns:
the last error message

Reimplemented from ADOConnection.

Definition at line 257 of file adodb-db2.inc.php.

References ADOConnection::ErrorMsg().

ADODB_db2::ErrorNo (  ) 

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

Reimplemented from ADOConnection.

Definition at line 266 of file adodb-db2.inc.php.

References ADOConnection::ErrorNo().

ADODB_db2::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 287 of file adodb-db2.inc.php.

ADODB_db2::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 296 of file adodb-db2.inc.php.

References RollbackTrans().

ADODB_db2::RollbackTrans (  ) 

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

Returns:
true/false.

Reimplemented from ADOConnection.

Definition at line 307 of file adodb-db2.inc.php.

Referenced by CommitTrans().

ADODB_db2::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.

Reimplemented from ADOConnection.

Definition at line 594 of file adodb-db2.inc.php.

ADODB_db2::UpdateBlob ( table,
column,
val,
where,
blobtype = 'BLOB' 
)

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.
