In the following example, the INTO clause in the second SELECT statement specifies that the table named ProductResults holds the final result set of the union of the selected columns of the ProductModel and Gloves tables. The Gloves table is created in the first SELECT statement.


Specifies the table used in the current query, replacing the current table name if one has already been specified. This is typically used in the sub-queries performed in the advanced where or union methods. Optional second argument for passing options:* only: if true, the ONLY keyword is used before the tableName to discard inheriting tables' data.

If you join on a column that has repeated values, you'll get many copies of the matching rows in the joined table. For example, there are two blue bricks. The toy Cuteasaurus is blue. So joining the tables on colour returns two copies of the row for Cuteasaurus:select * from toysjoin brickson toy_colour = brick_colour;Note that the keyword inner is optional.

This statement will allow the lookup to display a list of values with one row added to show 'No Subject' null value.(NOTE: We found that you cannot place the @[email protected] keyword in the second select statement for the union, the Lookup will not get registered if you attempt to do so.)

In the first statement, there are no duplicates in the union between TableB and TableC. Then, in the union between that set and TableA, the ALL keyword includes the duplicates. In the second statement, duplicates are included in the union between TableA and TableB but are eliminated in the subsequent union with TableC. The ALL keyword has no effect on the final result of this expression.

This conditional lets you compare an expression against another expression. You can use it to selectively retrieve only the relevant rows of a recordset. Like the comparison conditional, the BETWEEN conditional also compares; however, the BETWEEN conditional compares against a range of values. Therefore, its syntax requires two values, which are inclusive, a minimum and a maximum. Separate these values with the AND keyword.

Query of Queries supports the ORDER BY clause to sort. Make sure that it is the last clause in your SELECT statement. You can sort by multiple columns, by relative column position, by nonselected columns. You can specify a descending sort direction with the DESC keyword (by default, most RDBMS sorts are ascending, which makes the ASC keyword unnecessary).

Fragments allow for the reuse of common repeated selections of fields, reducing duplicated text in the document. Inline Fragments can be used directly within a selection to condition upon a type condition when querying against an interface or union.

Field selection is also determined by spreading fragments into one another. The selection set of the target fragment is unioned with the selection set at the level at which the target fragment is referenced. 041b061a72
