ADODB_pdo_pgsql::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 ADODB_pdo.

Definition at line 65 of file adodb-pdo_pgsql.inc.php.

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

Referenced by MetaTables().

& ADODB_pdo_pgsql::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 ADODB_pdo.

References ADOConnection::CacheExecute(), and ADOConnection::Execute().

& ADODB_pdo_pgsql::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 ADODB_pdo.

Definition at line 84 of file adodb-pdo_pgsql.inc.php.

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

& ADODB_pdo_pgsql::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 ADODB_pdo.
