MySQL error 1102 (ER_WRONG_DB_NAME) occurs when the database name in a CREATE, USE, or ALTER statement contains illegal characters or exceeds length limits.
MySQL Error 1102: ER_WRONG_DB_NAME appears when a CREATE, USE, or ALTER statement references an invalid database name. Check the identifier for length, reserved words, or illegal characters, then rerun the statement with a valid name to resolve the issue.
Incorrect database name '%s'
Error 1102 fires when MySQL cannot parse the supplied database identifier.
The server returns “Incorrect database name '%s'” and aborts the statement.
The error mainly arises in CREATE DATABASE, USE, RENAME, or ALTER SCHEMA statements where the identifier violates naming rules such as length limits or character restrictions.
Illegal characters like spaces, hyphens, or symbols trigger Error 1102 because the parser treats them as delimiters or operators.
Names longer than 64 characters exceed MySQL’s identifier limit and result in the same error message.
Reserved words used as database names without back-ticks also cause the server to respond with ER_WRONG_DB_NAME.
Validate the identifier first: stay under 64 characters, use letters, numbers, or underscores, and avoid leading digits.
Enclose reserved words in back-ticks or choose a different, descriptive name.
Retry the CREATE DATABASE or USE statement once the identifier conforms to MySQL naming conventions.
CI/CD scripts that assemble names from branch names often inject characters like / or -.
Sanitize inputs before executing SQL.
GUI tools may allow copy-pasting names with trailing spaces.
Trim whitespace in the editor or use Galaxy’s linting warnings.
Adopt a strict naming convention: snake_case, max 30 characters, no reserved words.
Add validation in migration pipelines to reject illegal identifiers at build time.
Use Galaxy’s AI copilot to auto-generate compliant database names when refactoring schemas.
Error 1064 (ER_PARSE_ERROR) appears when syntax errors exist elsewhere in the statement.
Error 1007 (ER_DB_CREATE_EXISTS) occurs if the database already exists.
Use CREATE DATABASE IF NOT EXISTS to bypass it.
Error 1049 (ER_BAD_DB_ERROR) means the database does not exist when issuing USE or SELECT statements.
.
No. Hyphens are interpreted as subtraction operators. Replace them with underscores.
MySQL limits identifiers, including database names, to 64 characters.
MySQL has no direct RENAME DATABASE command. Create a new database, move tables, then drop the old one, or use tools like mysqldump.
Yes. Galaxy warns about illegal identifiers in real time and can auto-correct names via its AI copilot.
