extractColumnValue

protected Object extractColumnValue(ResultSet resultSet,
                        String columnName,
                        int columnIdx,
                        int jdbcType)
                             throws DatabaseOperationException,
                                    SQLException

This is the core method to retrieve a value for a column from a result set. Its primary purpose is to call the appropriate method on the result set, and to provide an extension point where database-specific implementations can change this behavior.

Overrides:

extractColumnValue in class PlatformImplBase

Parameters:

resultSet - The result set to extract the value from

columnName - The name of the column; can be null in which case the columnIdx will be used instead

columnIdx - The index of the column's value in the result set; is only used if columnName is null

jdbcType - The jdbc type to extract

Returns:

The value

Throws:

SQLException - If an error occurred while accessing the result set

DatabaseOperationException

setStatementParameterValue

protected void setStatementParameterValue(PreparedStatement statement,
                              int sqlIndex,
                              int typeCode,
                              Object value)
                                   throws SQLException

This is the core method to set the parameter of a prepared statement to a given value. The primary purpose of this method is to call the appropriate method on the statement, and to give database-specific implementations the ability to change this behavior.

Overrides:

setStatementParameterValue in class PlatformImplBase

Parameters:

statement - The statement

sqlIndex - The parameter index

typeCode - The JDBC type code

value - The value

Throws:

SQLException - If an error occurred while setting the parameter value

fetch

public List fetch(Database model,
         String sql,
         Collection parameters,
         Table[] queryHints,
         int start,
         int end)
           throws DatabaseOperationException

Queries for a list of dyna beans representing rows of the given query. In contrast to the Platform.query(Database, String, Collection, Table[]) method all beans will be materialized and the connection will be closed before returning the beans. Also, the two int parameters specify which rows of the result set to use. If there are more rows than desired, they will be ignored (and not read from the database).

Specified by:

fetch in interface Platform

Overrides:

fetch in class PlatformImplBase

Parameters:

model - The database model to use

sql - The parameterized sql query

parameters - The parameter values

queryHints - The tables that are queried (optional)

start - Row number to start from (0 for first row)

end - Row number to stop at (inclusively; -1 for last row)

Returns:

The dyna beans resulting from the query

Throws:

DatabaseOperationException
