Member Function Documentation

actualType()

ADODB_DataDict::actualType ( $meta )

inherited

Returns the actual type given a character code.

C: varchar X: CLOB (character large object) or largest varchar size if CLOB is not supported C2: Multibyte varchar X2: Multibyte CLOB

B: BLOB (binary large object)

D: Date T: Date-time L: Integer field suitable for storing booleans (0 or 1) I: Integer F: Floating point number N: Numeric or decimal number

alterColumnSQL()

ADODB_DataDict::alterColumnSQL ( $tabname, $flds, $tableflds = '', $tableoptions = '' )

inherited

Change the definition of one column.

As some DBMs can't do that on their own, you need to supply the complete definition of the new table, to allow recreating the table and copying the content over to the new table

Parameters

string	$tabname	table-name
string	$flds	column-name and type for the changed column
string	$tableflds,=''	complete definition of the new table, eg. for postgres, default ''
array | string	$tableoptions,=''	options for the new table see createTableSQL, default ''

Return values

array

with SQL strings

Reimplemented in ADODB2_db2.

changeTableSQL()

ADODB_DataDict::changeTableSQL ( $tablename, $flds, $tableoptions = false, $dropOldFlds = false )

inherited

This function changes/adds new fields to your table.

You don't have to know if the col is new or not. It will check on its own.

Parameters

string	$tablename
string	$flds
string[]	$tableoptions
bool	$dropOldFlds

Return values

string[]

Array of SQL Commands

Reimplemented in ADODB2_db2.

createTableSQL()

ADODB_DataDict::createTableSQL ( $tabname, $flds, $tableoptions = array() )

inherited

Generate the SQL to create table.

Returns an array of sql strings.

dropColumnSQL()

ADODB_DataDict::dropColumnSQL ( $tabname, $flds, $tableflds = '', $tableoptions = '' )

inherited

Drop one column.

Some DBM's can't do that on their own, you need to supply the complete definition of the new table, to allow, recreating the table and copying the content over to the new table

Parameters

string	$tabname	table-name
string	$flds	column-name and type for the changed column
string	$tableflds,=''	complete definition of the new table, eg. for postgres, default ''
array | string	$tableoptions,=''	options for the new table see createTableSQL, default ''

Return values

array

with SQL strings

renameColumnSQL()

ADODB_DataDict::renameColumnSQL ( $tabname, $oldcolumn, $newcolumn, $flds = '' )

inherited

Rename one column.

Some DBMs can only do this together with changeing the type of the column (even if that stays the same, eg. mysql)

Parameters

string	$tabname	table-name
string	$oldcolumn	column-name to be renamed
string	$newcolumn	new column-name
string	$flds,=''	complete column-definition-string like for addColumnSQL, only used by mysql atm., default=''

Return values

array

with SQL strings

Member Data Documentation

$upperName

string ADODB_DataDict::$upperName

inherited

any varchar/char field this size or greater is treated as a blob in other words, we use a text area for editing.

Uppercase driver name
