Member Function Documentation

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::ErrorMsg  ) 
 

Returns:
the last error message

Reimplemented from ADOConnection.

Definition at line 788 of file adodb-postgres64.inc.php.

ADODB_postgres64::ErrorNo  ) 
 

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

Reimplemented from ADOConnection.

Definition at line 807 of file adodb-postgres64.inc.php.

References ADOConnection::MetaError().

& 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.

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 CommitTrans().

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.

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.
