Row

trait Row extends AnyRef

A Row allows you to extract Value's from a MySQL row.

Column values can be accessed by the MySQL column name via the typed xyzOrNull and getXyz methods. For example, stringOrNull and getString. The get-prefixed methods return Options and use None to represent a SQL NULL. For SQL NULLs, the or-suffixed methods return null for Object-types and use a sentinel, like 0, for primitives.

Alternatively, Value's based on the column name can be accessed via the apply method.

For example, given the query, SELECT 'text' AS str_col, 123 AS int_col, you could extract the columns as such.

First, in Scala:

import com.twitter.finagle.mysql.Row
val row: Row = ???

// if the column is not null:
val strCol: String = row.stringOrNull("str_col")
val intCol: Int = row.intOrZero("int_col")

// if the column is nullable:
val strCol: Option[String] = row.getString("str_col")
val intCol: Option[java.lang.Integer] = row.getInteger("int_col")

Then, the same in Java:

import com.twitter.finagle.mysql.Row;
import scala.Option;
Row row = ...

// if the column is not null:
String strCol = row.stringOrNull("str_col");
int intCol = row.intOrZero("int_col");

// if the column is nullable:
Option<String> strCol = row.getString("str_col");
Option<Integer> intCol = row.getInteger("int_col");

Abstract Value Members

abstract val fields: IndexedSeq[Field]
Contains a Field object for each column in the Row.
Contains a Field object for each column in the Row. The data is 0-indexed so fields(0) contains the column metadata for the first column in the Row.
abstract def indexOf(columnName: String): Option[Int]
Retrieves the 0-indexed index of the column with the given name.
Retrieves the 0-indexed index of the column with the given name.
columnName
the case sensitive name of the column.
returns
Some(Int) if the column exists with the given name. Otherwise, None.
abstract val values: IndexedSeq[Value]
The values for this Row.
The values for this Row. The data is 0-indexed so values(0) contains the value for the first column in the Row.
