Informix - Problem description

Problem IT42227 Status: Closed

UPDATE OF TABLE WITH TEXT COLUMN FAILS WITH ERROR -346/-124 WHENNUMBER OF
ROWS UPDATED IS LARGER THAN 32767

product:
INFORMIX SERVER / 5725A3900 / E10 - 
Problem description:
Running an update against a table with a referential constraint
sometimes fails with errors -346/-124 depending on number of
rows to update.

For example following two updates :

update tab1 set col8 = '1' where col1 = '92013144';
update tab1 set col8 = '1' where col1 = '11098572';

We can observe that first update runs fine for 8859 rows but
second fails with errors -346/-124 :

$ dbaccess cpctms query.sql

Database selected.
8859 row(s) updated.
  346: Could not update a row in the table.
  124: ISAM error: no begin work yet
Error in line 2
Near character position 66
Database closed.

But sometimes same update works fine and it updates 40162 rows :

$ dbaccess cpctms query.sql

Database selected.
8859 row(s) updated.
40162 row(s) updated.
Database closed.
