DB2 FOR LUW / DB2FORLUW / 970 - DB2

DB2 export command may incorrectly report a SQL27981W warning 
message. 
 
For example, any of the following will generate the warning 
SQL27981W message: 
db2 "export to abc.del of del values ('ABC ')" 
db2 "export to abc.del of del values ('ABC ' || ' ')" 
db2 "export to abc.del of del select tabname, 'ABC ' from 
syscat.tables" 
db2 "export to test.ixf of ixf select case when name='AAAA' then 
 '11' else '22' end from sysibm.systables" 
 
Example output: 
$ db2 "export to abc.del of del select tabname, 'ABC ' from 
syscat.tables" 
 
SQL3104N  The Export utility is beginning to export data to file 
"abc.del". 
 
SQL27981W  The utility could not verify presence of attached or 
detached data 
partitions in the target table or the source table. 
 
SQL3105N  The Export utility has finished exporting "360" rows. 
 
 
Number of rows exported: 360 
 
 
Explanation: DB2 scans and parses the select statement of an 
export command, and incorrectly determines that the first 
4-character token (from token 3 onwards) it finds as the FROM 
keyword, and the next token as the table name.  It then runs 
some internal SQL queries using the table name to determine 
table characteristics.  If it does not determine the correct 
FROM keyword (for example, a 4-character token precedes the real 
FROM keyword), then the internal SQL queries with the wrong 
table name may fail with syntax errors, and DB2 export will then 
return the SQL27891W warning message.

****************************************************************

The incorrect SQL27981W warning message can be ignored, or user 
can attempt to modify the export's select statement slightly so 
that it does not contain 4-character tokens preceding a valid 
FROM keyword, and still have the correct semantic meaning. 
 
For example, the following will not generate the warning: 
db2 "export to abc.del of del values ('ABC')" 
db2 "export to abc.del of del values ('ABC' || ' ')" 
db2 "export to abc.del of del values (cast ('ABC ' as char 
(4)))" 
db2 "export to abc.del of del select tabname, cast ('ABC ' as 
char (4)) from syscat.tables" 
db2 "export to test.ixf of ixf select case when DEPTNAME = 'AAA' 
then '11' else '22' end from org"
