+* Type: {Object}
+
+An object for getting and setting SQLite database limits at runtime.
+Each property corresponds to an SQLite limit and can be read or written.
+
+```js
+const db = new DatabaseSync(':memory:');
+
+// Read current limit
+console.log(db.limits.length);
+
+// Set a new limit
+db.limits.sqlLength = 100000;
+
+// Reset a limit to its compile-time maximum
+db.limits.sqlLength = Infinity;
+```
+
+Available properties: `length`, `sqlLength`, `column`, `exprDepth`,
+`compoundSelect`, `vdbeOp`, `functionArg`, `attach`, `likePatternLength`,
+`variableNumber`, `triggerDepth`.
+
+Setting a property to `Infinity` resets the limit to its compile-time maximum value.
