| 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 param: string $tabname table-name param: string $flds column-name and type for the changed column param: string $tableflds='' complete definition of the new table, eg. for postgres, default '' param: array|string $tableoptions='' options for the new table see createTableSQL, default '' return: array with SQL strings |
| renameColumnSQL($tabname,$oldcolumn,$newcolumn,$flds='') X-Ref |
