MySQL error 1065 (ER_EMPTY_QUERY) occurs when the server receives an empty SQL statement, usually due to malformed client code, missing semicolons, or accidental whitespace.
MySQL Error 1065: ER_EMPTY_QUERY happens when MySQL receives a blank statement instead of valid SQL. Trim whitespace, add the missing query text, or separate multiple statements with semicolons to resolve the issue quickly.
Query was empty
Error 1065 appears when the MySQL parser receives an empty command string.
The server cannot execute a blank query, so it returns the ER_EMPTY_QUERY error and SQLSTATE 42000.
The error frequently occurs in application code that programmatically builds SQL, interactive sessions where the user presses Enter on an empty line, or batch files with accidental blank statements.
Missing SQL text causes the parser to treat the statement length as zero, immediately triggering 1065.
Stripped comments or misplaced semicolons often leave nothing for MySQL to run.
Excessive whitespace, newline characters, or string-building logic that produces "" can deliver a null or empty string to the driver, leading to the same outcome.
First, confirm the client actually sends SQL by logging the final query string.
If it is empty, backtrack to the string-construction logic and ensure required clauses and semicolons exist.
In scripts or the MySQL CLI, verify each command ends with a semicolon and remove unintended blank lines. Use SET sql_notes = 1 to surface warnings that hint at missing statements.
ORMs sometimes strip all columns due to conditional logic, leaving SELECT without fields.
Add a default column list to avoid emptiness.
Stored procedures that concatenate user input can receive NULL. Use COALESCE or IFNULL to substitute a safe default before executing PREPARE.
Validate query strings before execution.
Assert LENGTH(query) > 0 in application code and fail fast.
Adopt linting or CI tools that scan migration files for consecutive semicolons (;;), which indicate an empty statement.
Error 1064 (syntax error) arises when partial statements remain after trimming an empty query. Fix by completing the SQL syntax.
Error 1172 occurs when SELECT returns more than one row into variables, often seen after resolving 1065 and adding a query; ensure LIMIT 1 is present.
.
No. The server is running but cannot execute an empty statement. Provide valid SQL to proceed.
Ignoring it hides logic bugs that remove query text. Always fix the root cause.
The segment between consecutive semicolons is an empty command that MySQL attempts to run.
