Datastage : Schema reconciliation detected a size mismatch in timestamp

by on Jul.31, 2017, under Error and Issues

Error Message: 

Schema reconciliation detected a size mismatch for column DT. When writing column DATETIME(fraction=6) into database column DATETIME(fraction=0), truncation, loss of precision, data corruption or padding can occur.


Resolution : 

This issue occurs when the source stream is read as times tamp with microseconds and when writing into target the time stamp field does not have microseconds scale.  There is no direct functions to truncate the microseconds scale, as a work-around below method can be used.

StringToTimestamp(TimestampToString(from_xfm.DT,"%yyyy-%mm-%dd %hh:%nn:%ss") ,"%yyyy-%mm-%dd %hh:%nn:%ss")

SQL0668N Operation not allowed for reason code “3” on table

by on Jul.24, 2017, under Error and Issues


SQLExecute reported: SQLSTATE = 57016: Native Error Code = -668: Msg = [IBM][CLI Driver][DB2/LINUXX8664] SQL0668N Operation not allowed for reason code “3” on table “XXX.XXXX”. SQLSTATE=57016



After doing several research the issue was the table was marked in check pending state due to bad bulk load without terminate in load statement.

Loading a null file to the table with the terminate command will clear the issue.

load from /dev/null of del terminate into XXX.XXXX

Sample :

SQL3110N The utility has completed processing. "0" rows were read from the
input file.

Number of rows read = 0
Number of rows skipped = 0
Number of rows loaded = 0
Number of rows rejected = 0
Number of rows deleted = 0
Number of rows committed = 0


Platform :

Datastage 11.5 on Linux &

DB2 10.5 on Linux
