-The optional parameter $dataTypes provides an array of [[dictionary:​metatype|metaTypes]] that match the columns in the table. This array forces a type onto each column. If the array is not provided, the driver probes each column in an attempt to discern the data types in the column. If results are ambiguous, the driver assigns a metaType of '​C'​. Better results are always obtained if the column types are defined, because the driver only recognize C,I and N types.+The optional parameter $dataTypes provides an array of [[v5:dictionary:​metatype|metaTypes]] that match the columns in the table.
