RE: Embedded SQL using IN and a host variable

Well, with your search value list being nicely formatted like that, couldn't you just use the LOCATE(Column3 , :path) > 0 in lieu of the IN(:path)... You might need to use trim(column3) if your :path string does not pad blanks in the search values list...

Subject: Embedded SQL using IN and a host variable

I have a need to accept a list of values that needs to be compared to a column in a table using an embedded SQL statement in RPGLE.

The list:

'data1'
'data2'

This list is assembled so that path looks like:

'data1','data2'

When used in the SQL statement...

Select stuff from table where column3 in (:path);

I end up with an SQLCod = 100.

Running the SQL outside of the program produces the needed data.

Select * from table where column3 in ('data1','data2');

Is there a solution short of repeating the condition over and over again? Using STRIP and TRIM with the host variable had no impact.

Stub of Code below:

dpath s 9999

dcolumn1 s 5
dcolumn2 s 3
dcolumn3 s 9999

/free
eval path = '''';
eval path = %trim(path) +
'data1' + '''';

eval path = %trim(path) + ',' + '''' +
'data2' + '''';

exec sql
declare get cursor with return to client for
SELECT distinct
Column1, Column2, Column3 FROM Table WHERE
Column3 in (:path);

exec sql open get;

exec sql fetch get into :Column1, :Column2, :Column3;

if sqlcod = sqlcod;
eval sqlcod = sqlcod;
endif;

/end-free
