<p>Error 1470 appears when a string exceeds the maximum length permitted for an ENUM, SET, identifier, or comment field.</p>
<p>MySQL Error 1470: ER_WRONG_STRING_LENGTH means the submitted string is longer than the object allows, such as an ENUM value over 255 characters. Shorten the value or redesign the column to a larger data type to resolve the problem.</p>
String '%s' is too long for %s (should be no longer than
MySQL throws error code 1470 with message String '%s' is too long for %s (should be no longer than %d when a literal or identifier surpasses an internal upper limit. The limit varies by context: 255 characters for an ENUM element, 64 for a SET element, or 1024 for comments.
The error occurs during CREATE or ALTER commands, data loads, and routine definitions where MySQL validates metadata before committing the change. It is detected at parse time, so the statement fails immediately.
Leaving the schema change unresolved blocks migrations and can halt deployments. Failing inserts that rely on the oversized value also interrupt application workflows, leading to user-visible errors.
Oversized ENUM or SET elements, overly long column or table comments, authentication plugin parameters, and identifier names longer than 64 characters commonly trigger the problem.
Reduce the offending string to meet the documented limit, split large literals into multiple smaller ENUM or SET options, or switch the column type to VARCHAR or TEXT when you need more characters.
An ENUM value longer than 255 characters can be moved into a VARCHAR column plus a CHECK constraint. A SET element over 64 characters can be broken into separate options. Long comments can be shortened or stored in a documentation table.
Validate string lengths in migrations, keep ENUM values concise, store verbose text in TEXT columns, and review MySQL documented limits during design. Galaxy's editor highlights the impending 1470 error before execution, preventing failed migrations.
Data too long for column (1406) occurs when data exceeds column length at runtime. Out of range value (1264) appears for numeric overflows. Not null violation (1048) surfaces when a required column receives NULL.
Each ENUM item is limited to 255 characters. Longer text generates error 1470 at table creation or alteration.
SET members may not surpass 64 characters. Oversized strings in DDL statements trigger the error.
Table, column, and index names must stay within 64 characters. Longer names are rejected by MySQL.
Column or table comments have a 1024 character ceiling. Exceeding this limit raises error 1470.
Authentication plugin names or arguments beyond their limits can also provoke the error.
Occurs when inserted data exceeds column length at runtime.
Raised when numeric data exceeds the allowed range.
Triggered when a NOT NULL column receives NULL.
No. ENUM elements are capped at 255 characters. Use VARCHAR or TEXT if you need more.
Yes, overly long parameter names or routine comments can trigger it during procedure creation.
Galaxy highlights MySQL limits inline and warns before executing DDL that would fail, saving time in migrations.
Lookup speed may drop slightly, but proper indexing on the VARCHAR column keeps performance acceptable for most workloads.
