Failure of odbc_num_rows sometimes

Posted by Bob Stearns on 11/28/05 01:07

When I have an Sql statement of the form:

SELECT LOC_ID,REPEAT('--',LEVELX)||NAMEX
FROM is3.locations
WHERE entity_id=2
AND (inactive='N' OR inactive IS NULL)
AND leftx BETWEEN 2 AND 983
ORDER BY LEFTX

odbc_num_rows returns -1. When I change the sql statement to:

SELECT LOC_ID,CHAR(LEVELX)||' '||NAMEX
FROM is3.locations
WHERE entity_id=2
AND (inactive='N' OR inactive IS NULL)
AND leftx BETWEEN 2 AND 983
ORDER BY LEFTX

odbc_num_rows returns the correct result.

Both statements work in the ADS development environment.

The rdms is db2 udb v8.1.9 linux

php is 4.4.0 with db2 compiled in
'./configure' '--prefix=/usr/local/php-4.4.0'
'--with-apxs2=/usr/local/apache2.0.54/bin/apxs'
'--with-ibm-db2=/db2home/db2inst1/sqllib'
'--with-openssl=/usr/local/ssl-0.9.8'
