Method Details

getChar

public char getChar(ResultSet resultSet,
 int columnIndex,
 JdbcTypeMapper.Context context,
 char defaultValue)
             throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Get a character value from the current row in the given ResultSet and column and convert to the target type. If the source value is null, return the given default value. A Context object is provided for additional context or "settings" regarding how to perform the conversion (for example, the source time zone). Only mappings that can logically be converted to a char need implement this method.

Overrides:

getChar in class JdbcTypeMapper.DataTypeMapping<Character>

Parameters:

resultSet - from which to extract the value.

columnIndex - ResultSet column from which to extract the value (1-based).

context - conversion context information.

defaultValue - value to return in case the source value is null.

Returns:

the converted value

Throws:

SQLException - if an error occurs

getObject

public Character getObject(ResultSet resultSet,
 int columnIndex,
 JdbcTypeMapper.Context context,
 Character defaultValue)
                    throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Get a value from the current row in the given ResultSet and column and convert to the target type. If the source value is null, return the given default value. A Context object is provided for additional context or "settings" regarding how to perform the conversion (for example, the source time zone).

Specified by:

getObject in class JdbcTypeMapper.DataTypeMapping<Character>

Parameters:

resultSet - from which to extract the value.

columnIndex - ResultSet column from which to extract the value (1-based).

context - conversion context information.

defaultValue - value to return in case the source value is null.

Returns:

the converted value

Throws:

SQLException - if an error occurs

bindChar

public void bindChar(PreparedStatement stmt,
 int parameterIndex,
 JdbcTypeMapper.Context context,
 char value)
              throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Bind the given character value to the given prepared statement. Implementations should avoid boxing and bind QueryConstants.NULL_CHAR values as SQL NULL.

Overrides:

bindChar in class JdbcTypeMapper.DataTypeMapping<Character>

Parameters:

stmt - statement to which to bind the given value

parameterIndex - parameter index to bind

context - context information for the binding

value - value to bind

Throws:

SQLException - if an error occurs

bindObject

public void bindObject(PreparedStatement stmt,
 int parameterIndex,
 JdbcTypeMapper.Context context,
 Character value)
                throws SQLException

Description copied from class: JdbcTypeMapper.DataTypeMapping

Bind the given value to the given prepared statement. All concrete implementations must provide this method. If the given value is null or matches the Deephaven null-equivalent, it should be bound as SQL NULL.

Specified by:

bindObject in class JdbcTypeMapper.DataTypeMapping<Character>

Parameters:

stmt - statement to which to bind the given value

parameterIndex - parameter index to bind

context - context information for the binding

value - value to bind

Throws:

SQLException - if an error occurs

columnSourceBinder

public JdbcTypeMapper.ColumnSourceBinder columnSourceBinder(ColumnSource columnSource,
 JdbcTypeMapper.Context context)

Description copied from class: JdbcTypeMapper.DataTypeMapping

Provides a function, via a lambda, that can be used to bind values from the given ColumnSource to a PreparedStatement.

Specified by:

columnSourceBinder in class JdbcTypeMapper.DataTypeMapping<Character>

Parameters:

columnSource - the column source from which values will be extracted

context - context information to use when binding

Returns:

a ColumnSourceBinder

columnSourcePrevBinder

public JdbcTypeMapper.ColumnSourceBinder columnSourcePrevBinder(ColumnSource columnSource,
 JdbcTypeMapper.Context context)

Description copied from class: JdbcTypeMapper.DataTypeMapping

Provides a function, via a lambda, that can be used to bind previous values from the given ColumnSource to a PreparedStatement.

Specified by:

columnSourcePrevBinder in class JdbcTypeMapper.DataTypeMapping<Character>

Parameters:

columnSource - the column source from which values will be extracted

context - context information to use when binding

Returns:

a ColumnSourceBinder
