SqlJdbcUtil

public SqlJdbcUtil()

Method Detail

isBoolean

public static boolean isBoolean(String fieldType)

Indicates whether the given field type represents a Boolean field. This convenience method is exactly equivalent to FieldType.BOOLEAN.matches(fieldType)

Parameters:

fieldType - the field type to check

Returns:

see above

makeFromClause

public static String makeFromClause(ModelEntity modelEntity,
                    DatasourceInfo datasourceInfo)
                             throws GenericEntityException

Makes the FROM clause and when necessary the JOIN clause(s) as well

Throws:

GenericEntityException

makeWhereStringFromFields

public static String makeWhereStringFromFields(List<ModelField> modelFields,
                               Map<String,?> fieldValues,
                               String operator)

Makes a WHERE clause String with "=?" if not null or " IS NULL" if null, all separated by the given operator.

Parameters:

modelFields - the fields to include in the WHERE string (can be null)

fieldValues - any field values to be checked against non-null values; keys are field (not column) names

operator - the operator to insert between each column condition in the returned WHERE string (typically "AND" or "OR")

Returns:

an empty string if the given list of fields is null or empty, otherwise a string like "first_name IS NULL OR last_name=?"

countWhereStringParametersFromFields

public static int countWhereStringParametersFromFields(List<ModelField> modelFields,
                                       Map<String,?> fieldValues)

makeWhereStringFromFields

public static String makeWhereStringFromFields(List<ModelField> modelFields,
                               Map<String,?> fieldValues,
                               String operator,
                               List<? super EntityConditionParam> entityConditionParams)

Makes a WHERE clause String with "=?" if not null or " IS NULL" if null, all separated by the given operator.

Parameters:

modelFields - the fields to include in the WHERE string (can be null)

fieldValues - any field values to be checked against non-null values; keys are field (not column) names

operator - the operator to insert between each column condition in the returned WHERE string (typically "AND" or "OR")

entityConditionParams - if not null, an element will be added to this list

Returns:

an empty string if the given list of fieldValues is null or empty, otherwise a string like "first_name IS NULL OR last_name=?"
