Public Methods

Method Description
Clone ( ) : SqlQuery

Creates a clone of the query.

Clones states like TrackAssignments, AssignedFields etc, creates a copy of Params dictionary

Dialect ( ) : ISqlDialect

Gets the dialect (SQL server type / version) for query.

Dialect ( ISqlDialect dialect ) : SqlQuery

Sets the dialect (SQL server type / version) for query.

TODO: SqlDialect system should be improved.

Distinct ( bool distinct ) : SqlQuery

Sets DISTINCT flag.

EnsureJoin ( Serenity.Data.Join join ) : SqlQuery
EnsureJoinsInExpression ( string expression ) : SqlQuery
ForXml ( string forXml ) : SqlQuery
From ( IAlias alias ) : SqlQuery

Adds a table to the FROM statement, with given short name.

This overload requires that alias has a table name.

From ( ISqlQuery subQuery, IAlias alias ) : SqlQuery

Adds a subquery to the FROM statement, with given short name.

This overload requires that alias has a table name.

From ( string table ) : SqlQuery

Adds a table to the FROM statement. When it is called more than once, puts a comma between table names (cross join)

From ( string table, IAlias alias ) : SqlQuery

Adds a table to the FROM statement with an alias. When it is called more than once, puts a comma between table names (cross join)

GroupBy ( IAlias alias, string fieldName ) : SqlQuery

Adds a field of a given table alias to the GROUP BY clause.

GroupBy ( string expression ) : SqlQuery

Adds a field name or an SQL expression to the GROUP BY clause.

Having ( string expression ) : SqlQuery

Adds an SQL expression to the GROUP BY clause.

InnerJoin ( IAlias alias, ICriteria onCriteria ) : SqlQuery
Join ( Serenity.Data.Join join ) : SqlQuery
LeftJoin ( IAlias alias, ICriteria onCriteria ) : SqlQuery
LeftJoin ( string toTable, IAlias alias, ICriteria onCriteria ) : SqlQuery
OrderBy ( IAlias alias, string fieldName, bool desc = false ) : SqlQuery

Adds a field of a given table alias to the ORDER BY clause.

OrderBy ( string expression, bool desc = false ) : SqlQuery

Adds a field name or an SQL expression to the ORDER BY clause.

OrderByFirst ( string expression, bool desc = false ) : SqlQuery

Inserts a field name or an SQL expression to the start of ORDER BY clause.

This method is designed to help apply user defined orders (for example by clicking headers on a grid) to a query with existing order. SQL server throws an error if a field is used more than once in ORDER BY expression, so this function first removes normal and DESC versions of the expression from the ORDER BY statement.

RightJoin ( IAlias alias, ICriteria onCriteria ) : SqlQuery
RightJoin ( string toTable, IAlias alias, ICriteria onCriteria ) : SqlQuery
Select ( IAlias alias, string fieldName ) : SqlQuery

Adds a field of a given table alias to the SELECT statement.

No column name is used for the field or expression.

Select ( IAlias alias, string fieldName, string columnName ) : SqlQuery

Adds a field of a given table alias to the SELECT statement with a column name.

Select ( ISqlQuery expression ) : SqlQuery

Adds a subquery to the SELECT statement.

Select ( ISqlQuery expression, string columnName ) : SqlQuery

Adds a subquery to the SELECT statement.

Select ( string expression ) : SqlQuery

Adds a field name or an SQL expression to the SELECT statement.

No column name is used for the field or expression.

Select ( string expression, string columnName ) : SqlQuery

Adds a field name or expression to the SELECT statement with a column name

SelectMany ( ) : SqlQuery

Adds field names or SQL expressions to the SELECT statement.

No aliases are used for the fields or expressions.

Skip ( int skipRows ) : SqlQuery

Sets SKIP value. Used for paging.

Skip ( ) : int

Gets current SKIP value.

SqlQuery ( ) : System

Creates a new SqlQuery instance.

SubQuery ( ) : SqlQuery

Creates a new query that shares parameter dictionary with this query.

Take ( int rowCount ) : SqlQuery

Sets TAKE/TOP value. Used for paging.

Take ( ) : int

Gets TAKE/TOP value.

ToString ( ) : string

SqlSelect sorgusunu formatlayıp bir SELECT sorgusuna çevirir. Sayfalama sözkonusuysa (atlanan kayıt varsa) birden fazla sorgu arka arkaya oluşturulur.

Where ( ) : SqlQuery

Adds expressions to WHERE clause, inserting AND between them.

Where ( string expression ) : SqlQuery

Adds an expression to WHERE clause. If query already has a WHERE clause, inserts AND between existing one and new one.

Private Methods

Method Description
AppendFromWhereOrderByGroupByHaving ( StringBuilder sb, string extraWhere, bool includeOrderBy ) : void

Verilen StringBuilder nesnesine SqlSelect'in FROM, WHERE, ORDER BY, GROUP BY, HAVING kısımlarını, belirtilirse bir ek filtre de gözönüne alınarak ekler.

Sayfalama için üretilen sorgularda SqlSelect'in bu kısımları iki ayrı yerde (birinde ek bir koşulla birlikte) kullanıldığından, bu şekilde yapılarak, kod tekrarının önüne geçilmiştir.

EnsureJoin ( string joinAlias ) : void
IFilterableQuery ( string expression ) : void

Implements IDBFilterable.Where, by calling original Where method.

IGetExpressionByName ( string columnName ) : string

Gets the source expression for a column name in the query.

This function uses a linear search in column list, so use with caution.

ISqlQueryExtensible ( IField field ) : int
ISqlQueryExtensible ( object row ) : void
JoinToString ( Serenity.Data.Join join, StringBuilder sb, bool modifySelf ) : void
