Method Details

getObject

public BigDecimal getObject(ResultSet resultSet, int columnIndex, JdbcTypeMapper.Context context, BigDecimal 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).

Overrides:

getObject in class JdbcTypeMapper.DecimalDataTypeMapping

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

getObjectCodec

public String getObjectCodec()

Overrides:

getObjectCodec in class JdbcTypeMapper.DecimalDataTypeMapping

getObjectCodecArguments

public String getObjectCodecArguments(ResultSetMetaData resultSetMetaData, String columnName)

Description copied from class: JdbcTypeMapper.DataTypeMapping

Provide the proper object codec arguments for the given ResultSetMetaData column. This permits the codec to allocate the minimum space that will accommodate the SQL type details (i.e. precision and scale).

Overrides:

getObjectCodecArguments in class JdbcTypeMapper.DecimalDataTypeMapping

Parameters:

resultSetMetaData - ResultSetMetaData to query

columnName - the column to query

Returns:

codec arguments consistent with the codec class provided by JdbcTypeMapper.DataTypeMapping.getObjectCodec()

bindObject

public void bindObject(PreparedStatement stmt, int parameterIndex, JdbcTypeMapper.Context context, BigDecimal 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.

Overrides:

bindObject in class JdbcTypeMapper.DecimalDataTypeMapping

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
