## Add regular expressions { #add-regular-expressions }

You can define a <abbr title="A regular expression, regex or regexp is a sequence of characters that define a search pattern for strings.">regular expression</abbr> `pattern` that the parameter should match:

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

This specific regular expression pattern checks that the received parameter value:

		queryDB      = tx
		rowsAffected int64
		batch        int
	)

	// user specified offset or limit
	var totalSize int
	if c, ok := tx.Statement.Clauses["LIMIT"]; ok {
		if limit, ok := c.Expression.(clause.Limit); ok {
			if limit.Limit != nil {
				totalSize = *limit.Limit
			}

			if totalSize > 0 && batchSize > totalSize {
				batchSize = totalSize
			}
