Methods

public

• concatenate() — Concatenates an array of column names or values.
• processLimit() — Method to modify a query already in string format with the needed additions to make the query limited to a particular number of results, or start at a particular offset.
• setLimit() — Sets the offset and limit for the result set, if the database driver supports it.
