SAP WHERE LOGEXP SELTAB documentation, setup help and example usage

ARTICLE
Short Reference

sql_cond - IN seltab

Syntax
... col [NOT] IN seltab ...

Effect
This expression is true if the value of the column col is (not) in the result set described in the rows of the selection table seltab . Any internal table with a row type that corresponds to that of a selection table can be specified as the selection table seltab . This includes, in particular, ranges tables .
The selection table is evaluated in the same way as in comparison expressions apart from the fact that in comparisons with the operators CP and NP the WHERE condition is case-sensitive, whereas in other comparison expressions it is not. The wildcard characters "*" and "+" of the selection options "CP" and "NP" are converted to the
OpenSQL wildcard characters "%" and "_", whereby the escape character "#" is also handled correctly. If "%" and "_" are contained in the te
mplate, an OpenSQL escape character is generated.

Notes

If the selection table contains invalid values, an exception that cannot be handled is raised.

If the selection table is initial, the expression is always true. If no conditions are specified apart from the expression above, all rows of the database table are selected if the selection table is initial.

The conditions specified in the selection table are passed by the database interface to the database as SQL statement input values. The maximum number of input values depends on the database system and is usually between 2000 and 10000. If

the maximum number is exceeded an exception of the class
CX_SY_OPEN_SQL_DB is raised.

Example
A selection table is filled as follows (the order of the rows is not important):
SIGN OPTION LOW HIGH
---------------------------------------
I EQ 01104711
I BT 10000000 19999999
I GE 90000000
E EQ 10000911
E BT 10000810 10000815
E CP 1%2##3#+4++5*
The following WHERE condition is generated from this:
... ( ID = '01104711' OR
ID BETWEEN '10000000' AND '19999999' OR
ID >= '90000000' ) AND
ID <(><<)>> '10000911' AND
ID NOT BETWEEN '10000810' AND '10000815' AND
ID NOT LIKE '1#%2##3+4__5%' ESCAPE '#' ...

Example
Reads flights with a primary key that corresponds to the user entries on the
selection screen .
DATA spfli_wa TYPE spfli.

SELECT-OPTIONS: s_carrid FOR spfli_wa-carrid NO INTERVALS
NO-EXTENSION,
s_connid FOR spfli_wa-connid NO INTERVALS
NO-EXTENSION.

SELECT SINGLE *
FROM spfli
INTO spfli_wa
WHERE carrid IN s_carrid AND
connid IN s_connid.
