Modifier and Type	Method	Description
protected java.lang.Object	convertToDataSetFieldType(java.lang.Object raw)	Converts the parameter from the raw type parameter to the correct internal Object type that is stored in the data set.

SFieldBytes

public SFieldBytes(SRecordMeta meta,
                   java.lang.String columnName,
                   int maxSize,
                   SFieldFlags... pvals)

Method Detail

queryFieldValue

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

Description copied from class: SFieldMeta

Issues a JDBC get*() on the result set for the field and converts the database type to the appropriate internal type, eg, Double for a double field. The first column has sqlIndex==1.

Specified by:

queryFieldValue in class SFieldMeta

Throws:

java.lang.Exception

convertToDataSetFieldType

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

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

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)

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
