Reference

Syntax

READ TABLE itab
           { {{FROM wa [USING KEY key_name|(name)]}
             |{WITH TABLE KEY [key_name|(name) COMPONENTS]
                              {comp_name1|(name1)} = dobj1
                              {comp_name2|(name2)} = dobj2
                              ...}
             | {WITH KEY comp1 = dobj1 comp2 = dobj2 ... [BINARY SEARCH]}
             | {WITH KEY key_name|(name)
                         COMPONENTS comp1 = dobj1 comp2 = dobj2 ... }
             | {INDEX idx [USING KEY key_name|(name)]} }
             | {WITH KEY dobj}
             | {WITH KEY = dobj [BINARY SEARCH]} }
           { {INTO wa
              [COMPARING { {comp1 comp2 ...}|{ALL FIELDS}|{NO FIELDS} }]
              [TRANSPORTING { {comp1 comp2 ...}|{ALL FIELDS} }]}
           | {ASSIGNING <fs> [CASTING]}
           | {REFERENCE INTO dref}
           | {TRANSPORTING NO FIELDS} }.

Effect

Reads a single line from an internal table itab.

Additions

• FROM wa
  Specifies the line to be read by matching it with the key values of a work area wa.

• WITH TABLE KEY
  ${comp_name1$|(name1)$} = dobj1 ${comp_name2$|(name2)$} = dobj2 ...
  Specifies the line to be read by specifying components of the primary table key statically or dynamically.

• WITH KEY comp1 = dobj1 comp2 = dobj2 ... $[BINARY SEARCH$]
  Specifies the line to be read by specifying components comp1, comp2, .... Appropriately sorted standard tables are searched using a binary search BINARY SEARCH.

• WITH KEY $[key_name$|(name) COMPONENTS$] comp1 = dobj1 comp2 = dobj2 ...
  Specifies the line to be read by specifying components comp1, comp2, ... for a table key.

• INDEX idx
  Specifies the line to be read by specifying the line number idx of a table index.

• KEY key_name$|(name)
  Specifies (statically or dynamically) a (secondary) table key used to find the line to be read.

• WITH KEY dobj $[BINARY SEARCH$]
  Obsolete: Reads the first line for which the left-aligned content matches the content of the data object dobj. The table line is cast to the type of dobj. Tables sorted accordingly are searched using the addition BINARY SEARCH.

• WITH KEY = dobj $[BINARY SEARCH$]
  Obsolete: Reads the first line whose entire content matches the content of the data object dobj. Appropriately sorted tables are sorted using a BINARY SEARCH.

• INTO wa
  Assigns the read line to a work area wa.

• COMPARING ${ ${comp1 comp2 ...$}$|${ALL FIELDS$}$|${NO FIELDS$} $}
  Compares the components comp1, comp2, ..., all components, or no components of a found line with the corresponding components of the work area and sets sy-subrc accordingly.

• TRANSPORTING ${ ${comp1 comp2 ...$}$|${ALL FIELDS$} $}
  Assigns the specified components comp1, comp2, ... or all components of the found line to the work area wa.

• ASSIGNING <fs> $[CASTING$]
  Assigns the line read to a field symbol <fs>; casting is an option.

• REFERENCE INTO dref
  Assigns the reference to the read line to a reference variable dref.

• TRANSPORTING NO FIELDS
  Does not assign the read line.
