Description

Class for connecting to PostgreSQL databases and performing common operations.

Properties

$_numericDataTypes
jump to class

array $_numericDataTypes = 'array'

Keys are UPPERCASE SQL datatypes or the constants Zend_Db::INT_TYPE, Zend_Db::BIGINT_TYPE, or Zend_Db::FLOAT_TYPE.

Values are: 0 = 32-bit integer 1 = 64-bit integer 2 = float or decimal

Details

$_numericDataTypes: array
Associative array of datatypes to values 0, 1, or 2.
visibility: protected
default: array
final: false
static: false

$_pdoType
jump to class

string $_pdoType = 'pgsql'

PDO type.

Details

$_pdoType: string
visibility: protected
default: pgsql
final: false
static: false

Methods

_connect
jump to class

_connect(
          
          )
        
        :
        void

describeTable
jump to class

describeTable(
          string $tableName, string $schemaName
              =
              null
          )
        
        :
        array

Returns the column descriptions for a table.

The return value is an associative array keyed by the column name, as returned by the RDBMS.

The value of each array element is an associative array with the following keys:

SCHEMA_NAME => string; name of database or schema TABLE_NAME => string; COLUMN_NAME => string; column name COLUMN_POSITION => number; ordinal position of column in table DATA_TYPE => string; SQL datatype name of column DEFAULT => string; default expression of column, null if none NULLABLE => boolean; true if column can have nulls LENGTH => number; length of CHAR/VARCHAR SCALE => number; scale of NUMERIC/DECIMAL PRECISION => number; precision of NUMERIC/DECIMAL UNSIGNED => boolean; unsigned property of an integer type PRIMARY => boolean; true if column is part of the primary key PRIMARY_POSITION => integer; position of column in primary key IDENTITY => integer; true if column is auto-generated with unique values

Arguments

$tableName: string
$schemaName: string
OPTIONAL

Output

array

final: false
static: false
todo: Discover integer unsigned property.

lastInsertId
jump to class

lastInsertId(
          string $tableName
              =
              null, string $primaryKey
              =
              null
          )
        
        :
        string

Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.

As a convention, on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2), this method forms the name of a sequence from the arguments and returns the last id generated by that sequence. On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method returns the last value generated for such a column, and the table name argument is disregarded.

Arguments

$tableName: string
OPTIONAL Name of table.
$primaryKey: string
OPTIONAL Name of primary key column.

Output

string

visibility: public
final: false
static: false

lastSequenceId
jump to class

lastSequenceId(
          string $sequenceName
          )
        
        :
        string

Return the most recent value from the specified sequence in the database.

This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.

Arguments

$sequenceName: string

Output

string

Details

visibility: public
final: false
static: false

limit
jump to class

limit(
          string $sql, integer $count, integer $offset
              =
              0
          )
        
        :
        string

Adds an adapter-specific LIMIT clause to the SELECT statement.

Arguments

$sql: string
$count: integer
$offset: integer
OPTIONAL

Output

string

listTables(
          
          )
        
        :
        array

Returns a list of the tables in the database.

Output

nextSequenceId(
          string $sequenceName
          )
        
        :
        string

Generate a new value from the specified sequence in the database, and return it.

This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.
