TQueryLinqExtensions.Join<TOuter,TInner,TKey,TResult>(DbEc<TOuter>, DbEc<TInner>, Expression<Func<TOuter,TKey>>, Expression<Func<TInner,TKey>>, Expression<Func<TOuter,TInner,TResult>>, JoinType) Method
Correlates the records of two TQuery recordsets based on matching keys.
public static DbEasyConnect.DbEc<TResult> Join<TOuter,TInner,TKey,TResult>(this DbEasyConnect.DbEc<TOuter> outer, DbEasyConnect.DbEc<TInner> inner, System.Linq.Expressions.Expression<System.Func<TOuter,TKey>> outerKeySelector, System.Linq.Expressions.Expression<System.Func<TInner,TKey>> innerKeySelector, System.Linq.Expressions.Expression<System.Func<TOuter,TInner,TResult>> resultSelector, DbEasyConnect.JoinType joinType=DbEasyConnect.JoinType.InnerJoin);
TOuter
The table type of the records of the first table.
TInner
The table type of the records of the second/joined table.
TKey
The type of the keys returned by the key selector functions.
TResult
The type of the result records.
outer DbEasyConnect.DbEc<TOuter>
The first DbEc<T> TQuery recordset to join.
inner DbEasyConnect.DbEc<TInner>
The second DbEc<T> TQuery recordset to join to the first TQuery recordset.
outerKeySelector System.Linq.Expressions.Expression<System.Func<TOuter,TKey>>
A function to extract the join key from each record of the first recordset.
innerKeySelector System.Linq.Expressions.Expression<System.Func<TInner,TKey>>
A function to extract the join key from each record of the second recordset.
resultSelector System.Linq.Expressions.Expression<System.Func<TOuter,TInner,TResult>>
A function to create a result record from two joined table records.
joinType JoinType
A join type selected by the DbEasyConnect.JoinType enum. Available options: InnerJoin, LeftJoin, RightJoin, FullJoin. If no option is selected, The default will be InnerJoin.
DbEasyConnect.DbEc<TResult>
An DbEc<T> that has records of type TResult obtained by performing
an inner join on two TQuery recordsets.
