' has a condition with a constant which is too long.
When PowerExchange executed SQL with a WHERE clause against data for Adabas, Datacom, IDMS, IMS or KSDS, the NRDB optimized reading process discarded a condition .The condition is still used for post-read qualification. PowerExchange cannot produce limit low and high values when a positive numeric constant exceeds 31 digits, or when a negative numeric constant exceeds 30 digits.
Processing continues, but the skipped condition causes too many records to be read, which causes slower overall processing.
If possible, construct the SQL WHERE clause condition using comparisons on fields that are used in a database key. Non-relational database keys with numeric fields of types NUM64U, UPACKED, UZONED typically have values that contain fewer than 30 digits. This message can be suppressed using parameter REPORT_UNUSED_OPT_READING_CONDITIONS=N.
