説明

<title>Description</title>

<command>ALTER ROUTINE</command> changes the definition of a routine, which can be an aggregate function, a normal function, or a procedure. See under <xref linkend="sql-alteraggregate"/>, <xref linkend="sql-alterfunction"/>, and <xref linkend="sql-alterprocedure"/> for the description of the parameters, more examples, and further details. ALTER ROUTINEはルーチン、すなわち、集約関数や通常の関数、プロシージャの定義を変更します。パラメータ説明や更なる例、より詳細については、ALTER AGGREGATE、ALTER FUNCTION、ALTER PROCEDUREを参照してください。

例

<title>Examples</title>

To rename the routine <literal>foo</literal> for type <type>integer</type> to <literal>foobar</literal>: integer型に対するルーチンfooをfoobarに名前変更します。

ALTER ROUTINE foo(integer) RENAME TO foobar;

This command will work independent of whether <literal>foo</literal> is an aggregate, function, or procedure. このコマンドはfooが集約、関数、プロシージャの何れであるかによらず動作します。

互換性

<title>Compatibility</title>

This statement is partially compatible with the <command>ALTER ROUTINE</command> statement in the SQL standard. See under <xref linkend="sql-alterfunction"/> and <xref linkend="sql-alterprocedure"/> for more details. Allowing routine names to refer to aggregate functions is a <productname>PostgreSQL</productname> extension. この文はSQL標準のALTER ROUTINE文と部分的に互換性があります。より詳しくはALTER FUNCTIONとALTER PROCEDUREを参照してください。ルーチン名が集約関数を参照できるのはPostgreSQLの拡張です。
