Simple clause

There are four main sentence structures in the English language.

Simple clause

If there is an ON clause then the ON expression is evaluated for each row of the cartesian product as a boolean expression. Only rows for which the expression evaluates to true are included from the dataset. If there is a USING clause then each of the column names specified must exist in the datasets to both the left and right of the join-operator.

For each pair of named columns, the expression "lhs. X" is evaluated for each row of the cartesian product as a boolean expression. Only rows for which all such expressions evaluates to true are included from the result set.

For each pair of columns identified by a USING clause, the column from the right-hand dataset is omitted from the joined dataset. The implicit USING Simple clause contains each of the column names that appear in both the left and right-hand input datasets.

If the left and right-hand input datasets feature no common column names, then the NATURAL keyword has no effect on the results of the join.

The added rows contain NULL values in the columns that would normally contain values copied from the right-hand input dataset. When more than two tables are joined together as part of a FROM clause, the join operations are processed in order from left to right. They are completely interchangeable in SQLite.

Only rows for which the WHERE clause expression evaluates to true are included from the dataset before continuing. A constraint of the form "left. Generation of the set of result rows. If the expression is the alias of a table or subquery in the FROM clause followed by ".

Each result row is calculated by evaluating the expressions in the result expression list with respect to a single row of input data or, for aggregate queries, with respect to a group of rows.

Each non-aggregate expression in the result-set is evaluated once for an arbitrarily selected row of the dataset. The same arbitrarily selected row is used for each non-aggregate expression. Or, if the dataset contains zero rows, then each non-aggregate expression is evaluated against a row consisting entirely of NULL values.

The single row of result-set data created by evaluating the aggregate and non-aggregate expressions in the result-set forms the result of an aggregate query without a GROUP BY clause. Each row is then assigned to a "group" based on the results; rows for which the results of evaluating the GROUP BY expressions are the same get assigned to the same group.

For the purposes of grouping rows, NULL values are considered equal. The usual rules for selecting a collation sequence with which to compare text values apply when evaluating expressions in a GROUP BY clause.A simple sentence has one independent clause.

That means it has one subject and one verb—although either or both can be compound. That means it has one subject and one verb—although either or both can be compound. where clause (C# Reference) 07/20/; 3 minutes to read { // Simple data source.

Arrays support IEnumerable. A where clause may appear either before or after a group clause depending on whether you have to filter the source elements before or after they are grouped. A simple sentence contains only one independent clause. An independent clause is a group of words that has a subject and a verb and can stand alone as a complete thought.

A simple gross-up clause for use in a variety of contracts, agreements and instruments. It provides for the payer of an amount to withhold tax only if required by law and, if so required, to make that amount up to (that is, gross up) the other party.
