| IWhereConditionTParent Methods |
The IWhereConditionTParent generic type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | And |
Changes the where operator to AND for subsequent where conditions. Use in combination of methods Where...
|
| And(IWhereCondition) |
Adds the given where condition with the AND operator
|
| And(ActionWhereCondition) |
Adds the given where condition with the AND operator. Creates a new where condition object and runs the setup actions on it.
|
| ApplyParametersTo |
Applies this where condition to the target object
(Inherited from IQueryParameters.) |
| Changed |
Marks the object as changed
(Inherited from IQueryObject.) |
| CloneObject |
Creates the clone of the object.
(Inherited from IQueryObject.) |
| CopyPropertiesTo |
Copies the properties to the target query.
(Inherited from IQueryParameters.) |
| EnsureParameters |
Ensures data parameters for the given query
(Inherited from IQueryParameters.) |
| Expand |
Expands the expression by replacing parameters with their values
(Inherited from IQueryParameters.) |
| GetTypedQuery |
Returns specifically typed instance of current Query object to allow user to compose Query in fluent syntax.
(Inherited from IQueryParametersTParent.) |
| IncludeDataParameters |
Adds the data parameters to the current query parameters
(Inherited from IQueryObject.) |
| NewWhere |
Clears the current where condition
|
| NoResults |
Sets the where condition to exclude all data from result
|
| Or |
Changes the where operator to OR for next where conditions. Use in combination of methods Where...
|
| Or(IWhereCondition) |
Adds the given where condition with the OR operator
|
| Or(ActionWhereCondition) |
Adds the given where condition with the OR operator. Creates a new where condition object and runs the setup actions on it.
|
| ReturnNoResults |
Sets the query to return no results. This action is irreversible, once the query is set to return no results it cannot be changed.
This method is used by data engine to forbid access to data that are not allowed to be accessed (e.g. license limitations), without notifying the process about the fact.
(Inherited from IWhereCondition.) |
| ToString |
Returns the string representation of the expression, with possibility of expanding parameters
(Inherited from IQueryParameters.) |
| Where(IWhereCondition) |
Adds the given where conditions to the query
|
| Where(ActionWhereCondition) |
Adds the given where condition to the query. Creates a new where condition object and runs the setup actions on it.
|
| Where(String, QueryDataParameters) |
Adds the given where condition to the query
|
| Where(String, QueryUnaryOperator) |
Adds the given where condition to the query. Matches the column value with an unary operator.
|
| Where(String, QueryOperator, Object) |
Adds the given where condition to the query. Matches the column to a given value.
|
| WhereContains |
Adds the condition for a string column to contain some substring
|
| WhereEmpty |
Adds the where condition for a null or empty column value
|
| WhereEquals |
Adds the given where condition to the query. Matches the column to a given value.
|
| WhereEqualsOrNull |
Adds the given where condition to the query. Matches the column to a given value or null value.
|
| WhereExists |
Adds where condition with EXISTS and the nested query "EXISTS (...)"
|
| WhereFalse |
Adds the where condition for a false column value (boolean column equals false).
|
| WhereID |
Adds the where condition to match the ID to the query. In case the column name is not provided or unknown, does not generate where condition. If given ID is invalid, adds the condition to match NULL.
|
| WhereIn(String, IDataQuery) |
Adds where condition to the nested query, e.g. "columnName IN (...)"
|
| WhereIn(String, ICollectionGuid) |
Adds where condition to the list of values, e.g. "columnName IN (...)"
|
| WhereIn(String, ICollectionInt32) |
Adds where condition to the list of values, e.g. "columnName IN (...)"
|
| WhereIn(String, ICollectionString) |
Adds where condition to the list of values, e.g. "columnName IN (...)"
|
| WhereLike |
Adds the given where condition to the query. Matches the column to a given value using LIKE operator.
|
| WhereNot |
Adds the negation of the given where condition
|
| WhereNotContains |
Adds the condition for a string column not to contain some substring
|
| WhereNotEmpty |
Adds the where condition for a non empty column value
|
| WhereNotExists |
Adds where condition with NOT EXISTS and the nested query "NOT EXISTS (...)"
|
| WhereNotIn(String, IDataQuery) |
Adds where condition to the nested query, e.g. "columnName NOT IN (...)"
|
| WhereNotIn(String, ICollectionGuid) |
Adds where condition to the list of values, e.g. "columnName NOT IN (...)"
|
| WhereNotIn(String, ICollectionInt32) |
