Insert Data into Table Syntax Part two

This Insert data into table is in continuation with previous post .

Variant 2

INSERT dbtab. or
INSERT *dbtab. or
INSERT (dbtabname) ...

Additions

1. ... FROM wa
2. ... CLIENT SPECIFIED

Effect

These are the SAP -specific short forms for the statements explained under variant 1.

  1. · INSERT INTO dbtab VALUES dbtab. or
  2. · INSERT INTO dbtab VALUES *dbtab. or
  3. · INSERT INTO (dbtabname) VALUES wa.
When the command has been executed, the system field SYDBCNT contains the number of inserted lines (0 or 1).

The return code value is set as follows:

SY-SUBRC = 0 Line successfully inserted.
SY_SUBRC = 4 Line could not be inserted, since a line with the same key already exists.

Example

Add a line to a database table:

TABLES SAIRPORT.
SAIRPORT-ID = 'NEW'.
SAIRPORT-NAME = 'NEWPORT APT'.
INSERT SAIRPORT.

Addition 1

... FROM wa

Effect

The values for the line to be inserted are not taken from the table work area dbtab , but from the explicitly specified work area wa . The work area wa must also satisfy the conditions described in variant 1. As with this variant, the addition allows you to specify the name of the database table directly or indirectly.

If a work area is not explicitly specified, the values for the line to be inserted are taken from the table work area dbtab if the statement is in a FORM or FUNCTION where the table work area is stored in a formal parameter or local variable of the same name.

Addition 2

... CLIENT SPECIFIED

Effect

As for variant 1.

Variant 3

INSERT dbtab FROM TABLE itab. or
INSERT (dbtabname) FROM TABLE itab.

Additions

... CLIENT SPECIFIED
... ACCEPTING DUPLICATE KEYS

Effect

Mass insert: Inserzts all lines of the internal table itab in a single operation. The lines of itab must satisfy the same conditions as the work area wa in variant 1.

When the command has been executed, the system field SYDBCNT contains the number of inserted lines.

If the internal table itab is empty, SY-SUBRC and SY-DBCNT are set to 0 after the call.

Addition 1

... CLIENT SPECIFIED

Effect

As for variant 1.

Addition 2

... ACCEPTING DUPLICATE KEYS

Effect

If a line cannot be inserted, the processing does not terminate with a runtime error, but the return code value of SY-SUBRC is merely set to 4. All the remaining lines are inserted when the
command is executed.

The return code value is set as follows:

SY-SUBRC = 0 All lines successfully inserted. Any other result causes a runtime error .(82.6)
