A positive literal LIMIT should not, by itself, return more rows than its value. First check the exact SQL and database engine: common explanations include SQL Server’s TOP (n) WITH TIES, a negative SQLite LIMIT expression, or a difference between the database result and what an application displays. Missing or incomplete ordering can make the selected rows unpredictable, but it does not explain a positive literal LIMIT being exceeded.
Start by checking the query that actually ran
The title alone does not identify the database or the statement, so there is no single cause to assume. Check these details before changing the query:

- Identify the database engine. The relevant rules differ between SQL Server, SQLite, MySQL, and PostgreSQL.
- Inspect the exact SQL sent to the database. Look for syntax such as
TOP (...) WITH TIES, or aLIMITexpression whose value is calculated rather than written as a positive number. - Compare counts at each layer. Check how many rows the database driver received and how many the application displays. If those counts differ, investigate fetching or display behavior separately from SQL.
Check the engine-specific exceptions
SQL Server: TOP (n) WITH TIES
SQL Server’s TOP (n) WITH TIES can return more than n rows when additional rows match the last selected row on every ORDER BY value. The WITH TIES option requires an ORDER BY. Microsoft Learn’s documentation gives an illustrative example in which 31 requested rows produce 33 because three employees named Brown tie at the boundary; that example demonstrates the rule, not how often it occurs.

Keep an ORDER BY if you need the chosen rows to be predictable; without a meaningful order, the query may still return the requested number, but which rows qualify is not reliably defined.

SQLite: evaluate the LIMIT expression
SQLite treats a negative LIMIT as having no upper bound. If the limit comes from a parameter, calculation, or application value, inspect the value after it is evaluated—not just the placeholder in the SQL. A NULL or non-convertible limit value produces an error rather than an unbounded result. SQLite: SELECT
MySQL and PostgreSQL: distinguish row choice from row count
In MySQL, LIMIT can affect the optimizer’s plan, and rows tied on all specified ordering columns can appear in any order. In PostgreSQL, using LIMIT or OFFSET without a predictable ORDER BY can produce inconsistent subsets across executions. These ordering behaviors affect which rows you see; they do not establish that a positive literal limit returns more rows than its value. MySQL: LIMIT query optimization · PostgreSQL: SELECT

Make LIMIT/OFFSET results stable
Add an ORDER BY that specifies the intended sequence, then include a unique tie-breaker so rows with equal sort values have a defined order. For example, if id is unique in your table, ORDER BY created_at, id makes ordering by creation time deterministic. Adapt the column names and sort direction to your schema and desired order. This stabilizes page membership; it does not change the limit’s row-count meaning.
If the counts still do not match
Count rows at the database/driver boundary and compare that number with the application’s displayed count. If the driver has no more rows than the limit but the interface shows more, inspect client-side fetching, accumulation, or display behavior. The available details do not identify a particular client, so the cause must be traced in the application that ran the query.
No frequency statistic is established by the cited engine documentation. To diagnose a specific incident, the necessary details are the database engine, exact SQL, evaluated limit value, ordering, and the point at which the extra rows first appear.
