    public class QSqlIndex

extends QSqlRecord
implements java.lang.Cloneable

The `QSqlIndex` class provides functions to manipulate and describe database indexes. An index refers to a single table or view in a database. Information about the fields that comprise the index can be used to generate SQL statements.

Constructor Detail

### QSqlIndex

    public QSqlIndex(QSqlIndex other)

  Constructs a copy of `other`.

### QSqlIndex

    public QSqlIndex(java.lang.String cursorName)

  Constructs an empty index using the cursor name `cursorname` and index name `name`.

### QSqlIndex

    public QSqlIndex()

  Constructs an empty index using the cursor name `cursorname` and index name `name`.

### QSqlIndex

    public QSqlIndex(java.lang.String cursorName,
                     java.lang.String name)

  Constructs an empty index using the cursor name `cursorname` and index name `name`.

Method Detail

### append

    public final void append(QSqlField field,
                             boolean desc)

  Appends the field `field` to the list of indexed fields. The field is appended with an ascending sort order, unless `desc` is true.

### cursorName

    public final java.lang.String cursorName()

  Returns the name of the cursor which the index is associated with.

See also:
  `setCursorName()`.

### isDescending

    public final boolean isDescending(int i)

  Returns true if field `i` in the index is sorted in descending order; otherwise returns false.

### name

    public final java.lang.String name()

  Returns the name of the index.

See also:
  `setName()`.

### setCursorName

    public final void setCursorName(java.lang.String cursorName)

  Sets the name of the cursor that the index is associated with to `cursorName`.

See also:
  `cursorName()`.

### setDescending

    public final void setDescending(int i,
                                    boolean desc)

  If `desc` is true, field `i` is sorted in descending order. Otherwise, field `i` is sorted in ascending order (the default). If the field does not exist, nothing happens.

See also:
  `isDescending()`.

### setName

    public final void setName(java.lang.String name)

  Sets the name of the index to `name`.

See also:
  `name()`.

### clone

    public QSqlIndex clone()

  This method is reimplemented for internal reasons

  Overrides:
    `clone` in class `QSqlRecord`
