+# DatabaseColumnsCount
+
+Gets the number of fields in a request.
+
+```
+int  DatabaseColumnsCount(
+   int  request      // request handle received in DatabasePrepare
+   );
+
+```
+
+Parameters
+
+request
+
+[in]  Request handle received in [DatabasePrepare()](/en/docs/database/databaseprepare).
+
+Return Value
+
+Number of fields or -1 in case of an error. To get the error code, use GetLastError(), the possible responses are:
+
+- ERR_DATABASE_INVALID_HANDLE (5121) - invalid request handle.
+
+Note
+
+There is no need to call the [DatabaseRead()](/en/docs/database/databaseread) function to get the number of fields of a request created in DatabasePrepare(). For the remaining DatabaseColumnXXX() functions, DatabaseRead() should be preliminarily called.
