MySQL throws error 1084 when a LOAD DATA or SELECT ... INTO OUTFILE statement uses a fixed-length field format on a table that contains BLOB or TEXT columns.
MySQL Error 1084: ER_BLOBS_AND_NO_TERMINATED occurs when LOAD DATA or SELECT … INTO OUTFILE tries to use fixed-length rows (FIELDS TERMINATED BY '') with a BLOB/TEXT column. Switch to a delimited format, e.g., FIELDS TERMINATED BY ',' to resolve the issue.
You can't use fixed rowlength with BLOBs; please use
Exact message: "You can't use fixed rowlength with BLOBs; please use FIELDS TERMINATED BY". The error is raised by MySQL when an import or export operation attempts to handle BLOB or TEXT columns with a fixed-length field specification.
Fixed-length mode is triggered when you set FIELDS TERMINATED BY '' in a LOAD DATA INFILE or SELECT … INTO OUTFILE statement.
Because BLOB and TEXT columns are variable sized, MySQL cannot calculate row length and aborts with error 1084.
The error appears during bulk data loading, data export, or replication scripts that rely on LOAD DATA.
It is version-independent and affects MySQL 5.x, 8.x, MariaDB, and Percona builds.
Developers usually meet the error after migrating legacy scripts that were written for tables without LOB columns or when adding a BLOB/TEXT column to an existing data-import workflow.
The bulk load will fail, leaving the target table empty or partially populated.
For high-volume ETL jobs this can break nightly pipelines, delay reporting, and require costly reruns.
Automated CI/CD processes may also mark deployments as failed when error 1084 occurs, blocking production releases until the script is corrected.
.
Yes. Fixed-length mode is safe as long as no BLOB or TEXT columns remain in the table definition.
No. Both MySQL 5.x and 8.x refuse fixed-length handling of BLOB/TEXT columns.
No. Packet size is unrelated. You must change the FIELDS TERMINATED BY clause.
Galaxy’s AI copilot inspects your LOAD DATA statement, warns about empty FIELDS TERMINATED BY, and proposes a delimiter, stopping the error pre-execution.
