Method Detail

queryFieldValue

public java.lang.Object queryFieldValue(java.sql.ResultSet rs,
                                        int sqlIndex)
                                 throws java.lang.Exception

Specidalizes abstract method to actually query a column from a result set.

Specified by:

queryFieldValue in class SFieldMeta

Throws:

java.lang.Exception

convertToDataSetFieldType

protected java.lang.Object convertToDataSetFieldType(java.lang.Object raw)
                                              throws java.lang.Exception

Description copied from class: SFieldMeta

Converts the parameter from the raw type parameter to the correct internal Object type that is stored in the data set. Returns the object if no conversion necessary. Used by SRecordInstance.setObject etc., Not getObject.

Specified by:

convertToDataSetFieldType in class SFieldMeta

Throws:

java.lang.Exception

defaultSqlDataType

public java.lang.String defaultSqlDataType()

Description copied from class: SFieldScalar

The default data type if not overriden by overrideSqlDataType. This is only called when the data type is actually needed by CREATE TABLE, ie if no sqlDataTypeOverride is specified.

Specified by:

defaultSqlDataType in class SFieldScalar

isFKeyCompatible

public boolean isFKeyCompatible(SFieldScalar field)

Description copied from class: SFieldScalar

Check if two fields can be used on both sides of a foreign key relation (same type, length, ...)

javaSqlType

public int javaSqlType()

Specified by:

javaSqlType in class SFieldScalar

Returns:

int constant from java.sql.Types, used for setting sql datatype with null values
