ADODB_postgres64::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 124 of file adodb-postgres64.inc.php.

References ADOConnection::_findvers(), and ADOConnection::GetOne().

Referenced by _connect(), and MetaTables().

ADODB_postgres64::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 173 of file adodb-postgres64.inc.php.

Referenced by RowLock().

ADODB_postgres64::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 187 of file adodb-postgres64.inc.php.

References RollbackTrans().

ADODB_postgres64::RollbackTrans (  ) 

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

Returns:
true/false.

Reimplemented from ADOConnection.

Definition at line 197 of file adodb-postgres64.inc.php.

Referenced by _close(), and CommitTrans().

& ADODB_postgres64::MetaTables ( ttype = false,
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 204 of file adodb-postgres64.inc.php.

References ADOConnection::MetaTables(), qstr(), and ServerInfo().

ADODB_postgres64::qstr ( s,
magic_quotes = false 
)

Correctly quotes a string so that all strings are escaped. We prefix and append to the string single-quotes. An example is $db->qstr("Don't bother",magic_quotes_runtime());

Parameters:
s the string to quote
[magic_quotes] if $s is GET/POST var, set to get_magic_quotes_gpc(). This undoes the stupidity of magic quotes for GPC.
Returns:
quoted string to be sent back to database

Reimplemented from ADOConnection.

Definition at line 237 of file adodb-postgres64.inc.php.

Referenced by _query(), MetaTables(), and UpdateBlob().

ADODB_postgres64::UpdateBlobFile ( table,
column,
path,
where,
blobtype = 'BLOB' 
)

Usage: UpdateBlob('TABLE', 'COLUMN', '/path/to/file', 'ID=1');

$blobtype supports 'BLOB' and 'CLOB'

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

Reimplemented from ADOConnection.

Definition at line 347 of file adodb-postgres64.inc.php.

References ADOConnection::UpdateBlob().

ADODB_postgres64::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.

Definition at line 442 of file adodb-postgres64.inc.php.

References BlobEncode(), ADOConnection::Execute(), and qstr().

& ADODB_postgres64::MetaColumns ( table,
normalize = 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.

Reimplemented in ADODB_netezza.

ADODB_postgres64::ErrorMsg (  ) 

Returns:
the last error message

Reimplemented from ADOConnection.

ADODB_postgres64::ErrorNo (  ) 

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