Effect

Defines a data type dtype.

Additions

• (len)
  Determines the length when referring to generic ABAP types.
• TYPE
  Determines the type by referring to a data type.
• LIKE
  Determines the type by referring to a data object.
• [LENGTH len] [DECIMALS dec]
  Determines the length and the number of fractional portions when referring to generic ABAP types.
• LINE OF
  Reference to the row type of an internal table.
• REF TO
  Generates a reference type.
• {[STANDARD] TABLE}|{SORTED TABLE}|{HASHED TABLE}|{ANY TABLE}|{INDEX TABLE}
  Generates a table type for non-generic table types standard, sorted or hashed tables or for the generic table types ANY TABLE or INDEX TABLE.
• WITH {[UNIQUE|NON-UNIQUE] {KEY [primary_key [ALIAS key_name] COMPONENTS] comp1 comp2 ...}}|{DEFAULT KEY}
  Defines a unique or non-unique primary table key primary_key. The components of the key are either specified explicitly or are defined by a standard key. You can use ALIAS to define an alias name key_name.
• WITH {UNIQUE HASHED}|{{UNIQUE|NON-UNIQUE} SORTED} KEY key_name COMPONENTS comp1 comp2 ...
  Defines a secondary table key key_name. It is managed using either a unique hash algorithm, a unique sorted secondary index, or a non-unique sorted secondary index.
• {WITH|WITHOUT} FURTHER SECONDARY KEYS
  Defines the genericness of the table type with respect to the secondary table key.
• INITIAL SIZE n
  Defines the initial memory usage of an internal table.
• RANGE OF
  Derives a ranges table with the row type of a selection table.
• READER|WRITER|LOCATOR|{LOB HANDLE} FOR ... COLUMNS ...
  Derives an LOB handle structure from the structure of a database table.
