Error 1103 occurs when MySQL encounters an invalid or empty table identifier, returning “Incorrect table name”.
MySQL Error 1103: ER_WRONG_TABLE_NAME means the server found an illegal or empty table identifier in your statement. Remove quotes, illegal symbols, or reserved words, then retry the command to resolve the error.
Incorrect table name '%s'
MySQL raises error 1103 with condition ER_WRONG_TABLE_NAME when it finds an invalid or empty identifier in any statement that references a table. The server stops parsing and returns “Incorrect table name ‘name’”.
The issue belongs to the SQL-state class 42000 (syntax error or access rule violation).
It prevents the statement from executing and must be fixed before retrying.
The parser throws the error during CREATE TABLE, ALTER TABLE, RENAME TABLE, INSERT, SELECT or JOIN operations whenever the provided name breaks MySQL identifier rules.
Automation scripts, migrations and interactive sessions all fail immediately, so catching the problem early keeps pipelines green.
Blocked DDL leaves databases half-migrated, stalls CI/CD pipelines and may cause downtime in blue-green deployments.
Fixing the root cause restores release velocity and data integrity.
Most failures stem from disallowed characters, starting the name with a number, using reserved keywords, exceeding 64 characters, or passing an empty string after dynamic SQL expansion.
Corrupted metadata or incompatible dump files from other database systems can also introduce illegal identifiers.
Inspect the failing statement, validate the identifier against MySQL naming rules, and rename or quote appropriately.
For generated SQL, print the final query to verify substitutions.
Apply ALTER TABLE ... RENAME or DROP/CREATE with a compliant name, then rerun the script.
Importing a dump from PostgreSQL often fails because double quotes create case-sensitive identifiers. Replace quotes or switch to backticks.
Temporary table generators sometimes return blank names.
Add defensive checks that raise errors before sending SQL to the server.
Adopt a naming convention that uses lowercase letters, numbers and underscores only. Enforce it with linters in your CI pipeline.
In Galaxy’s SQL editor, enable lint-on-save so illegal names are flagged before execution, reducing production incidents.
ER_BAD_DB_ERROR signals an invalid database name, while ER_NO_SUCH_TABLE reports a missing table.
Both require checking identifiers but differ in whether the name is illegal or simply nonexistent.
ER_BAD_FIELD_ERROR targets column names. Validate each identifier separately to isolate the failing part of complex queries.
.
Using spaces, hyphens, slashes or Unicode symbols violates MySQL naming rules and triggers Error 1103.
Identifiers cannot begin with digits unless quoted. Unquoted numeric prefixes cause syntax failure.
Words such as order or group conflict with SQL syntax.
Quoting or renaming resolves the clash.
MySQL silently truncates long names but still flags them as wrong when referenced later.
String concatenation bugs can yield blank identifiers that immediately raise ER_WRONG_TABLE_NAME.
.
Hyphens are not allowed unless the name is quoted with backticks, but quotes complicate queries. Prefer underscores.
No. Error 1103 is limited to real table identifiers. Column alias issues raise ER_WRONG_COLUMN_NAME.
Run your schema diff through mysql --dry-run or use Galaxy’s lint-on-save to flag violations before merge.
Yes. MySQL truncates longer names to 64 bytes and may still report them as incorrect when referenced.
