pack-priv final Class FunctionTable<R extends org.jooq.Record>

Implements org.jooq.QueryPartInternal.accept.

Doc from org.jooq.QueryPartInternal.accept.

This QueryPart can accept a Context object in order to render a SQL string or to bind its variables.

Annotations

@Override

Overrides org.jooq.impl.AbstractTable.as.

Implements org.jooq.Table.as.

Doc from org.jooq.Table.as.

Create an alias for this table.

Note that the case-sensitivity of the returned table depends on Settings#getRenderQuotedNames() and the Name. By default, table aliases are quoted, and thus case-sensitive in many SQL dialects - use DSL#unquotedName(String...) for case-insensitive aliases.

If the argument Name#getName() is qualified, then the Name#last() part will be used.

This method works both to alias the table as well as alias the table in its SelectField form via the SelectField#as(String) override. In order to alias only the projected table expression, use DSL#field(SelectField) to wrap this table into a Field

Parameters

as:Name

The alias name

Returns:Table<R>

The table alias

Implements org.jooq.Table.as.

Doc from org.jooq.Table.as.

Create an alias for this table and its fields.

Note that the case-sensitivity of the returned table depends on Settings#getRenderQuotedNames() and the Name. By default, table aliases are quoted, and thus case-sensitive in many SQL dialects - use DSL#unquotedName(String...) for case-insensitive aliases.

If the argument Name#getName() is qualified, then the Name#last() part will be used.

Derived column lists for table references

Note, not all databases support derived column lists for their table aliases. On the other hand, some databases do support derived column lists, but only for derived tables. jOOQ will try to turn table references into derived tables to make this syntax work. In other words, the following statements are equivalent:

-- Using derived column lists to rename columns (e.g. Postgres)
SELECT t.a, t.b
FROM my_table t(a, b)

-- Nesting table references within derived tables (e.g. SQL Server)
SELECT t.a, t.b
FROM (
  SELECT * FROM my_table
) t(a, b)

Derived column lists for derived tables

Other databases may not support derived column lists at all, but they do support common table expressions. The following statements are equivalent:

-- Using derived column lists to rename columns (e.g. Postgres)
SELECT t.a, t.b
FROM (
  SELECT 1, 2
) AS t(a, b)

-- Using UNION ALL to produce column names (e.g. MySQL)
SELECT t.a, t.b
FROM (
  SELECT null a, null b FROM DUAL WHERE 1 = 0
  UNION ALL
  SELECT 1, 2 FROM DUAL
) t

Parameters

as:Name

The alias name

fieldAliases:Name[]

The field aliases. Excess aliases are ignored, missing aliases will be substituted by this table's field names.

Returns:Table<R>

The table alias
