Method Detail

wrapException

public static MetaModelException wrapException(SQLException e,
                                               String actionDescription)
                                        throws MetaModelException

Throws:

MetaModelException

setStatementValue

public static void setStatementValue(PreparedStatement st,
                                     int valueIndex,
                                     Column column,
                                     Object value)
                              throws SQLException

Method which handles the action of setting a parameterized value on a statement. Traditionally this is done using the PreparedStatement.setObject(int, Object) method but for some types we use more specific setter methods.

Parameters:

st -

valueIndex -

column -

value -

Throws:

SQLException

getValueAsSql

public static String getValueAsSql(Column column,
                                   Object value,
                                   IQueryRewriter queryRewriter)

createWhereClause

public static String createWhereClause(List<FilterItem> whereItems,
                                       IQueryRewriter queryRewriter,
                                       boolean inlineValues)

isPreparedParameterCandidate

public static boolean isPreparedParameterCandidate(FilterItem whereItem)

Determines if a particular FilterItem will have it's parameter (operand) replaced during SQL generation. Such filter items should succesively have their parameters set at execution time.

Parameters:

whereItem -

Returns:

getTableTypesAsStrings

public static String[] getTableTypesAsStrings(TableType[] tableTypes)
