<p>MySQL raises ER_LIMITED_PART_RANGE (error 1523) when a partition handler receives a VALUES list containing numbers larger than 32-bit signed integers.</p>
<p>MySQL Error 1523: ER_LIMITED_PART_RANGE occurs when a partitioned table uses VALUES that exceed the 32-bit integer range. Convert the VALUES to signed 32-bit numbers or switch to RANGE COLUMNS or LIST COLUMNS partitions to solve the problem.</p>
The %s handler only supports 32 bit integers in VALUES
Error 1523 signals that the internal partition handler only supports 32-bit signed integers in the VALUES list. If a value lies outside the −2147483648 to 2147483647 range, MySQL blocks the statement.
The problem usually appears while creating or altering RANGE or LIST partitioned tables that rely on VALUES LESS THAN or VALUES IN clauses.
The error fires during CREATE TABLE, ALTER TABLE, or EXCHANGE PARTITION operations when the VALUES list includes an out-of-range literal or expression.
It can also occur while restoring dumps if legacy scripts define partitions with 64-bit identifiers.
Leaving the error unresolved blocks DDL operations, delays deployments, and prevents data ingestion. Production pipelines depending on new partitions will fail until the definition is corrected.
Using bigint literals in a VALUES list for RANGE or LIST partitions triggers the constraint because the original partition engine was hard-coded for 32-bit math.
Copy-pasting DDL from another database that supports 64-bit partitions also introduces oversized numbers.
Ensure every VALUES literal fits in a 32-bit signed integer. If data values exceed that range, migrate to RANGE COLUMNS or LIST COLUMNS partitioning, which supports larger numeric and date types.
For time-based partitions stored as epoch seconds, divide by 1000 to use seconds instead of milliseconds so the numbers stay below 2147483647.
For synthetic IDs, hash or modulo large keys into a smaller integer domain before listing them in VALUES.
Always validate partition literals against INT limits during code review. Prefer COLUMNS partitioning for bigint or date types to future-proof designs.
Use Galaxy’s SQL editor lint-rules to flag out-of-range literals before running DDL in production.
Similarly, ER_RANGE_NOT_IN_PARTITION triggers when an inserted value falls outside defined partitions. Ensure partition boundaries cover full data domain.
ER_PARTITION_FUNCTION_FAILURE appears when non-deterministic functions are used in partition keys. Replace with deterministic expressions.
Developers often paste 64-bit IDs directly into VALUES, breaching the 32-bit limit.
Using Unix timestamps in milliseconds quickly exceeds 32-bit storage, leading to the error during DDL.
DDL exported from PostgreSQL or Oracle may include large numeric ranges incompatible with MySQL partition handler.
Insert value does not match any partition boundary. Expand partition ranges.
Non-deterministic or unsupported function used in partition expression. Replace with deterministic function.
Partition encompasses entire data range, making other partitions unreachable. Adjust boundaries.
No. The classic partition handler is hard-coded for 32-bit INT. Use COLUMNS partitioning instead.
It only affects DDL. Inserts fail later with ER_NO_PARTITION_FOR_GIVEN_VALUE if the data value has no matching partition.
All MySQL 5.1 through 8.0 releases that rely on RANGE or LIST partitioning with VALUES lists enforce the 32-bit limit.
Galaxy’s AI copilot inspects VALUES lists and warns when literals exceed INT limits, preventing runtime DDL errors.
